a) clean up some declaration stuff (i.e., make more modern with respect to getting rid u_int for uint and so on). b) Turn back on 64 bit DAC support. Cheeze it a bit in that we have two DMA callback functions- one when we have bus_addr_t > 4 bits in width and the other which should be normal. Even Cheezier in that we turn off setting up DMA maps to be BUS_SPACE_MAXADDR if we're in ISP_TARGET_MODE. More work on this in a week or so. c) Tested under amd64 and 1MB DFLTPHYS, sparc64, i386 (PAE, but insufficient memory to really test > 4GB). LINT check under amd64. MFC after: 1 month

'Support' for ISP SBus cards. This code does not imply that SBus cards work yet. They hang for me. But I can't netboot the latest snapshot on my ultra1e, and things hang at bus_setup_intr time. Since I'm offline for a while, I thought I'd toss this in in case somebody else who has a bit better luck wants to fart around with it. Please try and wait until I get back to check things in.

----------- MISC CHANGES Add a new async event- ISP_TARGET_NOTIFY_ACK, that will guarantee eventual delivery of a NOTIFY ACK. This is tons better than just ignoring the return from isp_notify_ack and hoping for the best. Clean up the lower level lun enable code to be a bit more sensible. Fix a botch in isp_endcmd which was messing up the sense data. Fix notify ack for SRR to use a sensible error code in the case of a reject. Clean up and make clear what kind of firmware we've loaded and what capabilities it has. ----------- FULL (252 byte) SENSE DATA In CTIOs for the ISP, there's only a limimted amount of space to load SENSE DATA for associated CHECK CONDITIONS (24 or 26 bytes). This makes it difficult to send full SENSE DATA that can be up to 252 bytes. Implement MODE 2 responses which have us build the FCP Response in system memory which the ISP will put onto the wire directly. On the initiator side, the same problem occurs in that a command status response only has a limited amount of space for SENSE DATA. This data is supplemented by status continuation responses that the ISP pushes onto the response queue after the status response. We now pull them all together so that full sense data can be returned to the periph driver. This is supported on 23XX, 24XX and 25XX cards. This is also preparation for doing >16 byte CDBs. ----------- FC TAPE Implement full FC-TAPE on both initiator and target mode side. This capability is driven by firmware loaded, board type, board NVRAM settings, or hint configuration options to enable or disable. This is supported for 23XX, 24XX and 25XX cards. On the initiator side, we pretty much just have to generate a command reference number for each command we send out. This is FCP-4 compliant in that we do this per ITL nexus to generate the allowed 1 thru 255 CRN. In order to support the target side of FC-TAPE, we now pay attention to more of the PRLI word 3 parameters which will tell us whether an initiator wants confirmed responses. While we're at it, we'll pay attention to the initiator view too and report it. On sending back CTIOs, we will notice whether the initiator wants confirmed responses and we'll set up flags to do so. If a response or data frame is lost the initiator sends us an SRR (Sequence Retransmit Request) ELS which shows up as an SRR notify and all outstanding CTIOs are nuked with SRR Received status. The SRR notify contains the offset that the initiator wants us to restart the data transfer from or to retransmit the response frame. If the ISP driver still has the CCB around for which the data segment or response applies, it will retransmit. However, we typically don't know about a lost data frame until we send the FCP Response and the initiator totes up counters for data moved and notices missing segments. In this case we've already completed the data CCBs already and sent themn back up to the periph driver. Because there's no really clean mechanism yet in CAM to handle this, a hack has been put into place to complete the CTIO CCB with the CAM_MESSAGE_RECV status which will have a MODIFY DATA POINTER extended message in it. The internal ISP target groks this and ctl(8) will be modified to deal with this as well. At any rate, the data is retransmitted and an an FCP response is sent. The whole point here is to successfully complete a command so that you don't have to depend on ULP (SCSI) to have to recover, which in the case of tape is not really possible (hence the name FC-TAPE).

Save one more register read per command by not reading rqstoutrp register every time. The purpose of that register is unlikely output queue overflow detection, so read it only when its last known (and probably stale now) value signals overflow. This reduces CPU load and lock congestion and rises bottleneck in CTL while doing target mode via two 8Gbps ports from 100K to 120K IOPS.

Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer. Devote a single bit to mboxbsy- and set aside bits for output mbox registers that we need to pick up- we can have at least one command which does not have any defined output registers (MBOX_EXECUTE_FIRMWARE).

Push things closer to path failover by implementing loop down and gone device timers and zombie state entries. There are tunables that can be used to select a number of parameters. loop_down_limit - how long to wait for loop to come back up before declaring all devices dead (default 300 seconds) gone_device_time- how long to wait for a device that has appeared to leave the loop or fabric to reappear (default 30 seconds) Internal tunables include (which should be externalized): quick_boot_time- how long to wait when booting for loop to come up change_is_bad- whether or not to accept devices with the same WWNN/WWPN that reappear at a different PortID as being the 'same' device. Keen students of some of the subtle issues here will ask how one can keep devices from being re-accepted at all (the answer is to set a gone_device_time to zero- that effectively would be the same thing).

----------- MISC CHANGES Add a new async event- ISP_TARGET_NOTIFY_ACK, that will guarantee eventual delivery of a NOTIFY ACK. This is tons better than just ignoring the return from isp_notify_ack and hoping for the best. Clean up the lower level lun enable code to be a bit more sensible. Fix a botch in isp_endcmd which was messing up the sense data. Fix notify ack for SRR to use a sensible error code in the case of a reject. Clean up and make clear what kind of firmware we've loaded and what capabilities it has. ----------- FULL (252 byte) SENSE DATA In CTIOs for the ISP, there's only a limimted amount of space to load SENSE DATA for associated CHECK CONDITIONS (24 or 26 bytes). This makes it difficult to send full SENSE DATA that can be up to 252 bytes. Implement MODE 2 responses which have us build the FCP Response in system memory which the ISP will put onto the wire directly. On the initiator side, the same problem occurs in that a command status response only has a limited amount of space for SENSE DATA. This data is supplemented by status continuation responses that the ISP pushes onto the response queue after the status response. We now pull them all together so that full sense data can be returned to the periph driver. This is supported on 23XX, 24XX and 25XX cards. This is also preparation for doing >16 byte CDBs. ----------- FC TAPE Implement full FC-TAPE on both initiator and target mode side. This capability is driven by firmware loaded, board type, board NVRAM settings, or hint configuration options to enable or disable. This is supported for 23XX, 24XX and 25XX cards. On the initiator side, we pretty much just have to generate a command reference number for each command we send out. This is FCP-4 compliant in that we do this per ITL nexus to generate the allowed 1 thru 255 CRN. In order to support the target side of FC-TAPE, we now pay attention to more of the PRLI word 3 parameters which will tell us whether an initiator wants confirmed responses. While we're at it, we'll pay attention to the initiator view too and report it. On sending back CTIOs, we will notice whether the initiator wants confirmed responses and we'll set up flags to do so. If a response or data frame is lost the initiator sends us an SRR (Sequence Retransmit Request) ELS which shows up as an SRR notify and all outstanding CTIOs are nuked with SRR Received status. The SRR notify contains the offset that the initiator wants us to restart the data transfer from or to retransmit the response frame. If the ISP driver still has the CCB around for which the data segment or response applies, it will retransmit. However, we typically don't know about a lost data frame until we send the FCP Response and the initiator totes up counters for data moved and notices missing segments. In this case we've already completed the data CCBs already and sent themn back up to the periph driver. Because there's no really clean mechanism yet in CAM to handle this, a hack has been put into place to complete the CTIO CCB with the CAM_MESSAGE_RECV status which will have a MODIFY DATA POINTER extended message in it. The internal ISP target groks this and ctl(8) will be modified to deal with this as well. At any rate, the data is retransmitted and an an FCP response is sent. The whole point here is to successfully complete a command so that you don't have to depend on ULP (SCSI) to have to recover, which in the case of tape is not really possible (hence the name FC-TAPE).

Make virtual ports control asynchronous. Before this change virtual ports control IOCBs were executed synchronously via Execute IOCB mailbox command. It required exclusive use of scratch space of driver and mailbox registers of the hardware. Because of that shared resources use this code could not really sleep, having to spin for completion, blocking any other operation. This change introduces new asynchronous design, sending the IOCBs directly on request queue and gracefully waiting for their return on response queue. Returned IOCBs are identified with unified handle space from r292725.

Make virtual ports control asynchronous. Before this change virtual ports control IOCBs were executed synchronously via Execute IOCB mailbox command. It required exclusive use of scratch space of driver and mailbox registers of the hardware. Because of that shared resources use this code could not really sleep, having to spin for completion, blocking any other operation. This change introduces new asynchronous design, sending the IOCBs directly on request queue and gracefully waiting for their return on response queue. Returned IOCBs are identified with unified handle space from r292725.

Push things closer to path failover by implementing loop down and gone device timers and zombie state entries. There are tunables that can be used to select a number of parameters. loop_down_limit - how long to wait for loop to come back up before declaring all devices dead (default 300 seconds) gone_device_time- how long to wait for a device that has appeared to leave the loop or fabric to reappear (default 30 seconds) Internal tunables include (which should be externalized): quick_boot_time- how long to wait when booting for loop to come up change_is_bad- whether or not to accept devices with the same WWNN/WWPN that reappear at a different PortID as being the 'same' device. Keen students of some of the subtle issues here will ask how one can keep devices from being re-accepted at all (the answer is to set a gone_device_time to zero- that effectively would be the same thing).

Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer. Devote a single bit to mboxbsy- and set aside bits for output mbox registers that we need to pick up- we can have at least one command which does not have any defined output registers (MBOX_EXECUTE_FIRMWARE).

isp_get_hdr(ispsoftc_t *isp, isphdr_t *hpsrc, isphdr_t *hpdst)
Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating.

With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh.

----------- MISC CHANGES Add a new async event- ISP_TARGET_NOTIFY_ACK, that will guarantee eventual delivery of a NOTIFY ACK. This is tons better than just ignoring the return from isp_notify_ack and hoping for the best. Clean up the lower level lun enable code to be a bit more sensible. Fix a botch in isp_endcmd which was messing up the sense data. Fix notify ack for SRR to use a sensible error code in the case of a reject. Clean up and make clear what kind of firmware we've loaded and what capabilities it has. ----------- FULL (252 byte) SENSE DATA In CTIOs for the ISP, there's only a limimted amount of space to load SENSE DATA for associated CHECK CONDITIONS (24 or 26 bytes). This makes it difficult to send full SENSE DATA that can be up to 252 bytes. Implement MODE 2 responses which have us build the FCP Response in system memory which the ISP will put onto the wire directly. On the initiator side, the same problem occurs in that a command status response only has a limited amount of space for SENSE DATA. This data is supplemented by status continuation responses that the ISP pushes onto the response queue after the status response. We now pull them all together so that full sense data can be returned to the periph driver. This is supported on 23XX, 24XX and 25XX cards. This is also preparation for doing >16 byte CDBs. ----------- FC TAPE Implement full FC-TAPE on both initiator and target mode side. This capability is driven by firmware loaded, board type, board NVRAM settings, or hint configuration options to enable or disable. This is supported for 23XX, 24XX and 25XX cards. On the initiator side, we pretty much just have to generate a command reference number for each command we send out. This is FCP-4 compliant in that we do this per ITL nexus to generate the allowed 1 thru 255 CRN. In order to support the target side of FC-TAPE, we now pay attention to more of the PRLI word 3 parameters which will tell us whether an initiator wants confirmed responses. While we're at it, we'll pay attention to the initiator view too and report it. On sending back CTIOs, we will notice whether the initiator wants confirmed responses and we'll set up flags to do so. If a response or data frame is lost the initiator sends us an SRR (Sequence Retransmit Request) ELS which shows up as an SRR notify and all outstanding CTIOs are nuked with SRR Received status. The SRR notify contains the offset that the initiator wants us to restart the data transfer from or to retransmit the response frame. If the ISP driver still has the CCB around for which the data segment or response applies, it will retransmit. However, we typically don't know about a lost data frame until we send the FCP Response and the initiator totes up counters for data moved and notices missing segments. In this case we've already completed the data CCBs already and sent themn back up to the periph driver. Because there's no really clean mechanism yet in CAM to handle this, a hack has been put into place to complete the CTIO CCB with the CAM_MESSAGE_RECV status which will have a MODIFY DATA POINTER extended message in it. The internal ISP target groks this and ctl(8) will be modified to deal with this as well. At any rate, the data is retransmitted and an an FCP response is sent. The whole point here is to successfully complete a command so that you don't have to depend on ULP (SCSI) to have to recover, which in the case of tape is not really possible (hence the name FC-TAPE).

Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it.

It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer.

Recover from some major omissions/problems with the 24XX port. First, we were never correctly checking for a 24XX Status Type 0 response- that cased us to fall through to evaluate status for commands as if this were a 2100/2200/2300 Status Type 0 response. This is *close*, but not quite the same. This has been reported to be apparent with some wierd lun configuration problems with some arrays. It became glaringly apparent on sparc64 where none of the correct byte swap things were done. Fixing this omission then caused a whole universe shifting debug cycle of endian issues for the 2400. The manual for 24XX f/w turns out to be wrong about the endianness of a couple of entities. The lun and cdb fields for the type 7 request are *not* unconditionally big endian- they happen to be opposite of whatever the endian of the current machine type is. Same with the sense data for the 24XX type 0 response. While we're at it investigate and resolve some NVRAM endian issues. Approved by: re (ken) MFC after: 3 days

Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer. Devote a single bit to mboxbsy- and set aside bits for output mbox registers that we need to pick up- we can have at least one command which does not have any defined output registers (MBOX_EXECUTE_FIRMWARE).

----------- MISC CHANGES Add a new async event- ISP_TARGET_NOTIFY_ACK, that will guarantee eventual delivery of a NOTIFY ACK. This is tons better than just ignoring the return from isp_notify_ack and hoping for the best. Clean up the lower level lun enable code to be a bit more sensible. Fix a botch in isp_endcmd which was messing up the sense data. Fix notify ack for SRR to use a sensible error code in the case of a reject. Clean up and make clear what kind of firmware we've loaded and what capabilities it has. ----------- FULL (252 byte) SENSE DATA In CTIOs for the ISP, there's only a limimted amount of space to load SENSE DATA for associated CHECK CONDITIONS (24 or 26 bytes). This makes it difficult to send full SENSE DATA that can be up to 252 bytes. Implement MODE 2 responses which have us build the FCP Response in system memory which the ISP will put onto the wire directly. On the initiator side, the same problem occurs in that a command status response only has a limited amount of space for SENSE DATA. This data is supplemented by status continuation responses that the ISP pushes onto the response queue after the status response. We now pull them all together so that full sense data can be returned to the periph driver. This is supported on 23XX, 24XX and 25XX cards. This is also preparation for doing >16 byte CDBs. ----------- FC TAPE Implement full FC-TAPE on both initiator and target mode side. This capability is driven by firmware loaded, board type, board NVRAM settings, or hint configuration options to enable or disable. This is supported for 23XX, 24XX and 25XX cards. On the initiator side, we pretty much just have to generate a command reference number for each command we send out. This is FCP-4 compliant in that we do this per ITL nexus to generate the allowed 1 thru 255 CRN. In order to support the target side of FC-TAPE, we now pay attention to more of the PRLI word 3 parameters which will tell us whether an initiator wants confirmed responses. While we're at it, we'll pay attention to the initiator view too and report it. On sending back CTIOs, we will notice whether the initiator wants confirmed responses and we'll set up flags to do so. If a response or data frame is lost the initiator sends us an SRR (Sequence Retransmit Request) ELS which shows up as an SRR notify and all outstanding CTIOs are nuked with SRR Received status. The SRR notify contains the offset that the initiator wants us to restart the data transfer from or to retransmit the response frame. If the ISP driver still has the CCB around for which the data segment or response applies, it will retransmit. However, we typically don't know about a lost data frame until we send the FCP Response and the initiator totes up counters for data moved and notices missing segments. In this case we've already completed the data CCBs already and sent themn back up to the periph driver. Because there's no really clean mechanism yet in CAM to handle this, a hack has been put into place to complete the CTIO CCB with the CAM_MESSAGE_RECV status which will have a MODIFY DATA POINTER extended message in it. The internal ISP target groks this and ctl(8) will be modified to deal with this as well. At any rate, the data is retransmitted and an an FCP response is sent. The whole point here is to successfully complete a command so that you don't have to depend on ULP (SCSI) to have to recover, which in the case of tape is not really possible (hence the name FC-TAPE).

Recover from some major omissions/problems with the 24XX port. First, we were never correctly checking for a 24XX Status Type 0 response- that cased us to fall through to evaluate status for commands as if this were a 2100/2200/2300 Status Type 0 response. This is *close*, but not quite the same. This has been reported to be apparent with some wierd lun configuration problems with some arrays. It became glaringly apparent on sparc64 where none of the correct byte swap things were done. Fixing this omission then caused a whole universe shifting debug cycle of endian issues for the 2400. The manual for 24XX f/w turns out to be wrong about the endianness of a couple of entities. The lun and cdb fields for the type 7 request are *not* unconditionally big endian- they happen to be opposite of whatever the endian of the current machine type is. Same with the sense data for the 24XX type 0 response. While we're at it investigate and resolve some NVRAM endian issues. Approved by: re (ken) MFC after: 3 days

Recover from some major omissions/problems with the 24XX port. First, we were never correctly checking for a 24XX Status Type 0 response- that cased us to fall through to evaluate status for commands as if this were a 2100/2200/2300 Status Type 0 response. This is *close*, but not quite the same. This has been reported to be apparent with some wierd lun configuration problems with some arrays. It became glaringly apparent on sparc64 where none of the correct byte swap things were done. Fixing this omission then caused a whole universe shifting debug cycle of endian issues for the 2400. The manual for 24XX f/w turns out to be wrong about the endianness of a couple of entities. The lun and cdb fields for the type 7 request are *not* unconditionally big endian- they happen to be opposite of whatever the endian of the current machine type is. Same with the sense data for the 24XX type 0 response. While we're at it investigate and resolve some NVRAM endian issues. Approved by: re (ken) MFC after: 3 days

Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer. Devote a single bit to mboxbsy- and set aside bits for output mbox registers that we need to pick up- we can have at least one command which does not have any defined output registers (MBOX_EXECUTE_FIRMWARE).

Cheeze it a bit in that we have two DMA callback functions- one when we have bus_addr_t > 4 bits in width and the other which should be normal. Even Cheezier in that we turn off setting up DMA maps to be BUS_SPACE_MAXADDR if we're in ISP_TARGET_MODE.

Remove use of inlines and use the functions as a library. Larger code space, possibly performance hit, but more portable. Certainly less questionable use of inlining. Suggested by: des

isp_put_icb(ispsoftc_t *isp, isp_icb_t *src, isp_icb_t *dst)
Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer. Devote a single bit to mboxbsy- and set aside bits for output mbox registers that we need to pick up- we can have at least one command which does not have any defined output registers (MBOX_EXECUTE_FIRMWARE).

Reimplement enable and implement disable of virtual ports. Now on 24xx and above chips it is really possible to simulate several virtual FC ports with single physical one. For example, it allows to configure several targets in ctl.conf, assign each of them to separate virtual port, and let user to control access to them with switch zoning. I still doubt that all problems are solved there, but at now it passes at least basic tests.

Fix some incorrectly swapped fields in an ICB. Access a PCI register with correct width. Obtained from: Dmitry Valeryevich Trikoz
2005-05-11 03:00:50 +00:00
}
Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer. Devote a single bit to mboxbsy- and set aside bits for output mbox registers that we need to pick up- we can have at least one command which does not have any defined output registers (MBOX_EXECUTE_FIRMWARE).

It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer.

Fix bus dma segment count to be based off of MAXPHYS, not BUS_SPACE_MAXSIZE. Grumble. I've seen better documented architectures out of Redmond. Redo fabric evaluation to not use GET ALL NEXT (GA_NXT). Switches seem to be trying to wriggle out of supporting this well. Instead, use GID_FT to get a list of Port IDs and then use GPN_ID/GNN_ID to find the port and node wwn. This should make working on fabrics a bit cleaner and more stable. This also caused some cleanup of SNS subcommand canonicalization so that we can actually check for FS_ACC and FS_RJT, and if we get an FS_RJT, print out the reason and explanation codes. We'll keep the old GA_NXT method around if people want to uncomment a controlling definition in ispvar.h. This also had us clean up ISPASYNC_FABRICDEV to use a local lportdb argument and to have the caller explicitly say that a device is at the end of the fabric list. MFC after: 1 week

Improve/fix loop scanning routine. For the most of chips (except anscient ones) port handlers have no relation to port IDs. In such situation old code scanning first 125 handlers was quite naive. Instead of doing that, send to chip single request to get full list of port handlers available on specific virtual port and scan only them. Old code had problems with case of several virtual ports enabled, when port handlers allocated from global address space could easily go above 125. This change was successfully tested on 23xx, 24xx and 25xx chips in loop mode with 4 virtual initiator ports, each seing 50 virtual target ports.

a) clean up some declaration stuff (i.e., make more modern with respect to getting rid u_int for uint and so on). b) Turn back on 64 bit DAC support. Cheeze it a bit in that we have two DMA callback functions- one when we have bus_addr_t > 4 bits in width and the other which should be normal. Even Cheezier in that we turn off setting up DMA maps to be BUS_SPACE_MAXADDR if we're in ISP_TARGET_MODE. More work on this in a week or so. c) Tested under amd64 and 1MB DFLTPHYS, sparc64, i386 (PAE, but insufficient memory to really test > 4GB). LINT check under amd64. MFC after: 1 month

isp_put_sns_request(ispsoftc_t *isp, sns_screq_t *src, sns_screq_t *dst)
Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer. Devote a single bit to mboxbsy- and set aside bits for output mbox registers that we need to pick up- we can have at least one command which does not have any defined output registers (MBOX_EXECUTE_FIRMWARE).

isp_get_sns_response(ispsoftc_t *isp, sns_scrsp_t *src, sns_scrsp_t *dst, int nwords)
Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer. Devote a single bit to mboxbsy- and set aside bits for output mbox registers that we need to pick up- we can have at least one command which does not have any defined output registers (MBOX_EXECUTE_FIRMWARE).

----------- MISC CHANGES Add a new async event- ISP_TARGET_NOTIFY_ACK, that will guarantee eventual delivery of a NOTIFY ACK. This is tons better than just ignoring the return from isp_notify_ack and hoping for the best. Clean up the lower level lun enable code to be a bit more sensible. Fix a botch in isp_endcmd which was messing up the sense data. Fix notify ack for SRR to use a sensible error code in the case of a reject. Clean up and make clear what kind of firmware we've loaded and what capabilities it has. ----------- FULL (252 byte) SENSE DATA In CTIOs for the ISP, there's only a limimted amount of space to load SENSE DATA for associated CHECK CONDITIONS (24 or 26 bytes). This makes it difficult to send full SENSE DATA that can be up to 252 bytes. Implement MODE 2 responses which have us build the FCP Response in system memory which the ISP will put onto the wire directly. On the initiator side, the same problem occurs in that a command status response only has a limited amount of space for SENSE DATA. This data is supplemented by status continuation responses that the ISP pushes onto the response queue after the status response. We now pull them all together so that full sense data can be returned to the periph driver. This is supported on 23XX, 24XX and 25XX cards. This is also preparation for doing >16 byte CDBs. ----------- FC TAPE Implement full FC-TAPE on both initiator and target mode side. This capability is driven by firmware loaded, board type, board NVRAM settings, or hint configuration options to enable or disable. This is supported for 23XX, 24XX and 25XX cards. On the initiator side, we pretty much just have to generate a command reference number for each command we send out. This is FCP-4 compliant in that we do this per ITL nexus to generate the allowed 1 thru 255 CRN. In order to support the target side of FC-TAPE, we now pay attention to more of the PRLI word 3 parameters which will tell us whether an initiator wants confirmed responses. While we're at it, we'll pay attention to the initiator view too and report it. On sending back CTIOs, we will notice whether the initiator wants confirmed responses and we'll set up flags to do so. If a response or data frame is lost the initiator sends us an SRR (Sequence Retransmit Request) ELS which shows up as an SRR notify and all outstanding CTIOs are nuked with SRR Received status. The SRR notify contains the offset that the initiator wants us to restart the data transfer from or to retransmit the response frame. If the ISP driver still has the CCB around for which the data segment or response applies, it will retransmit. However, we typically don't know about a lost data frame until we send the FCP Response and the initiator totes up counters for data moved and notices missing segments. In this case we've already completed the data CCBs already and sent themn back up to the periph driver. Because there's no really clean mechanism yet in CAM to handle this, a hack has been put into place to complete the CTIO CCB with the CAM_MESSAGE_RECV status which will have a MODIFY DATA POINTER extended message in it. The internal ISP target groks this and ctl(8) will be modified to deal with this as well. At any rate, the data is retransmitted and an an FCP response is sent.

Remove use of inlines and use the functions as a library. Larger code space, possibly performance hit, but more portable. Certainly less questionable use of inlining. Suggested by: des

----------- MISC CHANGES Add a new async event- ISP_TARGET_NOTIFY_ACK, that will guarantee eventual delivery of a NOTIFY ACK. This is tons better than just ignoring the return from isp_notify_ack and hoping for the best. Clean up the lower level lun enable code to be a bit more sensible. Fix a botch in isp_endcmd which was messing up the sense data. Fix notify ack for SRR to use a sensible error code in the case of a reject. Clean up and make clear what kind of firmware we've loaded and what capabilities it has. ----------- FULL (252 byte) SENSE DATA In CTIOs for the ISP, there's only a limimted amount of space to load SENSE DATA for associated CHECK CONDITIONS (24 or 26 bytes). This makes it difficult to send full SENSE DATA that can be up to 252 bytes. Implement MODE 2 responses which have us build the FCP Response in system memory which the ISP will put onto the wire directly. On the initiator side, the same problem occurs in that a command status response only has a limited amount of space for SENSE DATA. This data is supplemented by status continuation responses that the ISP pushes onto the response queue after the status response. We now pull them all together so that full sense data can be returned to the periph driver. This is supported on 23XX, 24XX and 25XX cards. This is also preparation for doing >16 byte CDBs. ----------- FC TAPE Implement full FC-TAPE on both initiator and target mode side. This capability is driven by firmware loaded, board type, board NVRAM settings, or hint configuration options to enable or disable. This is supported for 23XX, 24XX and 25XX cards. On the initiator side, we pretty much just have to generate a command reference number for each command we send out. This is FCP-4 compliant in that we do this per ITL nexus to generate the allowed 1 thru 255 CRN. In order to support the target side of FC-TAPE, we now pay attention to more of the PRLI word 3 parameters which will tell us whether an initiator wants confirmed responses. While we're at it, we'll pay attention to the initiator view too and report it. On sending back CTIOs, we will notice whether the initiator wants confirmed responses and we'll set up flags to do so. If a response or data frame is lost the initiator sends us an SRR (Sequence Retransmit Request) ELS which shows up as an SRR notify and all outstanding CTIOs are nuked with SRR Received status. The SRR notify contains the offset that the initiator wants us to restart the data transfer from or to retransmit the response frame. If the ISP driver still has the CCB around for which the data segment or response applies, it will retransmit. However, we typically don't know about a lost data frame until we send the FCP Response and the initiator totes up counters for data moved and notices missing segments. In this case we've already completed the data CCBs already and sent themn back up to the periph driver. Because there's no really clean mechanism yet in CAM to handle this, a hack has been put into place to complete the CTIO CCB with the CAM_MESSAGE_RECV status which will have a MODIFY DATA POINTER extended message in it. The internal ISP target groks this and ctl(8) will be modified to deal with this as well. At any rate, the data is retransmitted and an an FCP response is sent. The whole point here is to successfully complete a command so that you don't have to depend on ULP (SCSI) to have to recover, which in the case of tape is not really possible (hence the name FC-TAPE).

In order to support the target side of FC-TAPE, we now pay attention to more of the PRLI word 3 parameters which will tell us whether an initiator wants confirmed responses. While we're at it, we'll pay attention to the initiator view too and report it. On sending back CTIOs, we will notice whether the initiator wants confirmed responses and we'll set up flags to do so. If a response or data frame is lost the initiator sends us an SRR (Sequence Retransmit Request) ELS which shows up as an SRR notify and all outstanding CTIOs are nuked with SRR Received status. The SRR notify contains the offset that the initiator wants us to restart the data transfer from or to retransmit the response frame. If the ISP driver still has the CCB around for which the data segment or response applies, it will retransmit. However, we typically don't know about a lost data frame until we send the FCP Response and the initiator totes up counters for data moved and notices missing segments. In this case we've already completed the data CCBs already and sent themn back up to the periph driver. Because there's no really clean mechanism yet in CAM to handle this, a hack has been put into place to complete the CTIO CCB with the CAM_MESSAGE_RECV status which will have a MODIFY DATA POINTER extended message in it. The internal ISP target groks this and ctl(8) will be modified to deal with this as well. At any rate, the data is retransmitted and an an FCP response is sent. The whole point here is to successfully complete a command so that you don't have to depend on ULP (SCSI) to have to recover, which in the case of tape is not really possible (hence the name FC-TAPE).

----------- MISC CHANGES Add a new async event- ISP_TARGET_NOTIFY_ACK, that will guarantee eventual delivery of a NOTIFY ACK. This is tons better than just ignoring the return from isp_notify_ack and hoping for the best. Clean up the lower level lun enable code to be a bit more sensible. Fix a botch in isp_endcmd which was messing up the sense data. Fix notify ack for SRR to use a sensible error code in the case of a reject. Clean up and make clear what kind of firmware we've loaded and what capabilities it has. ----------- FULL (252 byte) SENSE DATA In CTIOs for the ISP, there's only a limimted amount of space to load SENSE DATA for associated CHECK CONDITIONS (24 or 26 bytes). This makes it difficult to send full SENSE DATA that can be up to 252 bytes. Implement MODE 2 responses which have us build the FCP Response in system memory which the ISP will put onto the wire directly. On the initiator side, the same problem occurs in that a command status response only has a limited amount of space for SENSE DATA. This data is supplemented by status continuation responses that the ISP pushes onto the response queue after the status response. We now pull them all together so that full sense data can be returned to the periph driver. This is supported on 23XX, 24XX and 25XX cards. This is also preparation for doing >16 byte CDBs. ----------- FC TAPE Implement full FC-TAPE on both initiator and target mode side.

The whole point here is to successfully complete a command so that you don't have to depend on ULP (SCSI) to have to recover, which in the case of tape is not really possible (hence the name FC-TAPE).

----------- MISC CHANGES Add a new async event- ISP_TARGET_NOTIFY_ACK, that will guarantee eventual delivery of a NOTIFY ACK. This is tons better than just ignoring the return from isp_notify_ack and hoping for the best. Clean up the lower level lun enable code to be a bit more sensible. Fix a botch in isp_endcmd which was messing up the sense data. Fix notify ack for SRR to use a sensible error code in the case of a reject. Clean up and make clear what kind of firmware we've loaded and what capabilities it has. ----------- FULL (252 byte) SENSE DATA In CTIOs for the ISP, there's only a limimted amount of space to load SENSE DATA for associated CHECK CONDITIONS (24 or 26 bytes). This makes it difficult to send full SENSE DATA that can be up to 252 bytes. Implement MODE 2 responses which have us build the FCP Response in system memory which the ISP will put onto the wire directly. On the initiator side, the same problem occurs in that a command status response only has a limited amount of space for SENSE DATA. This data is supplemented by status continuation responses that the ISP pushes onto the response queue after the status response. We now pull them all together so that full sense data can be returned to the periph driver. This is supported on 23XX, 24XX and 25XX cards. This is also preparation for doing >16 byte CDBs. ----------- FC TAPE Implement full FC-TAPE on both initiator and target mode side. This capability is driven by firmware loaded, board type, board NVRAM settings, or hint configuration options to enable or disable. This is supported for 23XX, 24XX and 25XX cards. On the initiator side, we pretty much just have to generate a command reference number for each command we send out. This is FCP-4 compliant in that we do this per ITL nexus to generate the allowed 1 thru 255 CRN. In order to support the target side of FC-TAPE, we now pay attention to more of the PRLI word 3 parameters which will tell us whether an initiator wants confirmed responses. While we're at it, we'll pay attention to the initiator view too and report it. On sending back CTIOs, we will notice whether the initiator wants confirmed responses and we'll set up flags to do so. If a response or data frame is lost the initiator sends us an SRR (Sequence Retransmit Request) ELS which shows up as an SRR notify and all outstanding CTIOs are nuked with SRR Received status. The SRR notify contains the offset that the initiator wants us to restart the data transfer from or to retransmit the response frame. If the ISP driver still has the CCB around for which the data segment or response applies, it will retransmit. However, we typically don't know about a lost data frame until we send the FCP Response and the initiator totes up counters for data moved and notices missing segments. In this case we've already completed the data CCBs already and sent themn back up to the periph driver.

In order to support the target side of FC-TAPE, we now pay attention to more of the PRLI word 3 parameters which will tell us whether an initiator wants confirmed responses. While we're at it, we'll pay attention to the initiator view too and report it. On sending back CTIOs, we will notice whether the initiator wants confirmed responses and we'll set up flags to do so. If a response or data frame is lost the initiator sends us an SRR (Sequence Retransmit Request) ELS which shows up as an SRR notify and all outstanding CTIOs are nuked with SRR Received status. The SRR notify contains the offset that the initiator wants us to restart the data transfer from or to retransmit the response frame. If the ISP driver still has the CCB around for which the data segment or response applies, it will retransmit. However, we typically don't know about a lost data frame until we send the FCP Response and the initiator totes up counters for data moved and notices missing segments. In this case we've already completed the data CCBs already and sent themn back up to the periph driver. Because there's no really clean mechanism yet in CAM to handle this, a hack has been put into place to complete the CTIO CCB with the CAM_MESSAGE_RECV status which will have a MODIFY DATA POINTER extended message in it. The internal ISP target groks this and ctl(8) will be modified to deal with this as well. At any rate, the data is retransmitted and an an FCP response is sent.

isp_put_atio2(ispsoftc_t *isp, at2_entry_t *src, at2_entry_t *dst)
Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh.

Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer.

Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating.

Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer.

Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating.

----------- MISC CHANGES Add a new async event- ISP_TARGET_NOTIFY_ACK, that will guarantee eventual delivery of a NOTIFY ACK. This is tons better than just ignoring the return from isp_notify_ack and hoping for the best. Clean up the lower level lun enable code to be a bit more sensible. Fix a botch in isp_endcmd which was messing up the sense data. Fix notify ack for SRR to use a sensible error code in the case of a reject. Clean up and make clear what kind of firmware we've loaded and what capabilities it has. ----------- FULL (252 byte) SENSE DATA In CTIOs for the ISP, there's only a limimted amount of space to load SENSE DATA for associated CHECK CONDITIONS (24 or 26 bytes). This makes it difficult to send full SENSE DATA that can be up to 252 bytes. Implement MODE 2 responses which have us build the FCP Response in system memory which the ISP will put onto the wire directly. On the initiator side, the same problem occurs in that a command status response only has a limited amount of space for SENSE DATA. This data is supplemented by status continuation responses that the ISP pushes onto the response queue after the status response. We now pull them all together so that full sense data can be returned to the periph driver. This is supported on 23XX, 24XX and 25XX cards. This is also preparation for doing >16 byte CDBs. ----------- FC TAPE Implement full FC-TAPE on both initiator and target mode side. This capability is driven by firmware loaded, board type, board NVRAM settings, or hint configuration options to enable or disable. This is supported for 23XX, 24XX and 25XX cards. On the initiator side, we pretty much just have to generate a command reference number for each command we send out. This is FCP-4 compliant in that we do this per ITL nexus to generate the allowed 1 thru 255 CRN. In order to support the target side of FC-TAPE, we now pay attention to more of the PRLI word 3 parameters which will tell us whether an initiator wants confirmed responses. While we're at it, we'll pay attention to the initiator view too and report it. On sending back CTIOs, we will notice whether the initiator wants confirmed responses and we'll set up flags to do so. If a response or data frame is lost the initiator sends us an SRR (Sequence Retransmit Request) ELS which shows up as an SRR notify and all outstanding CTIOs are nuked with SRR Received status. The SRR notify contains the offset that the initiator wants us to restart the data transfer from or to retransmit the response frame. If the ISP driver still has the CCB around for which the data segment or response applies, it will retransmit. However, we typically don't know about a lost data frame until we send the FCP Response and the initiator totes up counters for data moved and notices missing segments. In this case we've already completed the data CCBs already and sent themn back up to the periph driver. Because there's no really clean mechanism yet in CAM to handle this, a hack has been put into place to complete the CTIO CCB with the CAM_MESSAGE_RECV status which will have a MODIFY DATA POINTER extended message in it. The internal ISP target groks this and ctl(8) will be modified to deal with this as well. At any rate, the data is retransmitted and an an FCP response is sent. The whole point here is to successfully complete a command so that you don't have to depend on ULP (SCSI) to have to recover, which in the case of tape is not really possible (hence the name FC-TAPE).

----------- MISC CHANGES Add a new async event- ISP_TARGET_NOTIFY_ACK, that will guarantee eventual delivery of a NOTIFY ACK. This is tons better than just ignoring the return from isp_notify_ack and hoping for the best. Clean up the lower level lun enable code to be a bit more sensible. Fix a botch in isp_endcmd which was messing up the sense data. Fix notify ack for SRR to use a sensible error code in the case of a reject. Clean up and make clear what kind of firmware we've loaded and what capabilities it has. ----------- FULL (252 byte) SENSE DATA In CTIOs for the ISP, there's only a limimted amount of space to load SENSE DATA for associated CHECK CONDITIONS (24 or 26 bytes). This makes it difficult to send full SENSE DATA that can be up to 252 bytes. Implement MODE 2 responses which have us build the FCP Response in system memory which the ISP will put onto the wire directly. On the initiator side, the same problem occurs in that a command status response only has a limited amount of space for SENSE DATA. This data is supplemented by status continuation responses that the ISP pushes onto the response queue after the status response. We now pull them all together so that full sense data can be returned to the periph driver. This is supported on 23XX, 24XX and 25XX cards. This is also preparation for doing >16 byte CDBs. ----------- FC TAPE Implement full FC-TAPE on both initiator and target mode side. This capability is driven by firmware loaded, board type, board NVRAM settings, or hint configuration options to enable or disable. This is supported for 23XX, 24XX and 25XX cards. On the initiator side, we pretty much just have to generate a command reference number for each command we send out. This is FCP-4 compliant in that we do this per ITL nexus to generate the allowed 1 thru 255 CRN. In order to support the target side of FC-TAPE, we now pay attention to more of the PRLI word 3 parameters which will tell us whether an initiator wants confirmed responses. While we're at it, we'll pay attention to the initiator view too and report it. On sending back CTIOs, we will notice whether the initiator wants confirmed responses and we'll set up flags to do so. If a response or data frame is lost the initiator sends us an SRR (Sequence Retransmit Request) ELS which shows up as an SRR notify and all outstanding CTIOs are nuked with SRR Received status. The SRR notify contains the offset that the initiator wants us to restart the data transfer from or to retransmit the response frame. If the ISP driver still has the CCB around for which the data segment or response applies, it will retransmit. However, we typically don't know about a lost data frame until we send the FCP Response and the initiator totes up counters for data moved and notices missing segments. In this case we've already completed the data CCBs already and sent themn back up to the periph driver. Because there's no really clean mechanism yet in CAM to handle this, a hack has been put into place to complete the CTIO CCB with the CAM_MESSAGE_RECV status which will have a MODIFY DATA POINTER extended message in it.

The whole point here is to successfully complete a command so that you don't have to depend on ULP (SCSI) to have to recover, which in the case of tape is not really possible (hence the name FC-TAPE).

In order to support the target side of FC-TAPE, we now pay attention to more of the PRLI word 3 parameters which will tell us whether an initiator wants confirmed responses. While we're at it, we'll pay attention to the initiator view too and report it. On sending back CTIOs, we will notice whether the initiator wants confirmed responses and we'll set up flags to do so. If a response or data frame is lost the initiator sends us an SRR (Sequence Retransmit Request) ELS which shows up as an SRR notify and all outstanding CTIOs are nuked with SRR Received status. The SRR notify contains the offset that the initiator wants us to restart the data transfer from or to retransmit the response frame. If the ISP driver still has the CCB around for which the data segment or response applies, it will retransmit. However, we typically don't know about a lost data frame until we send the FCP Response and the initiator totes up counters for data moved and notices missing segments. In this case we've already completed the data CCBs already and sent themn back up to the periph driver. Because there's no really clean mechanism yet in CAM to handle this, a hack has been put into place to complete the CTIO CCB with the CAM_MESSAGE_RECV status which will have a MODIFY DATA POINTER extended message in it. The internal ISP target groks this and ctl(8) will be modified to deal with this as well. At any rate, the data is retransmitted and an an FCP response is sent. The whole point here is to successfully complete a command so that you don't have to depend on ULP (SCSI) to have to recover, which in the case of tape is not really possible (hence the name FC-TAPE).

----------- MISC CHANGES Add a new async event- ISP_TARGET_NOTIFY_ACK, that will guarantee eventual delivery of a NOTIFY ACK. This is tons better than just ignoring the return from isp_notify_ack and hoping for the best. Clean up the lower level lun enable code to be a bit more sensible. Fix a botch in isp_endcmd which was messing up the sense data. Fix notify ack for SRR to use a sensible error code in the case of a reject. Clean up and make clear what kind of firmware we've loaded and what capabilities it has. ----------- FULL (252 byte) SENSE DATA In CTIOs for the ISP, there's only a limimted amount of space to load SENSE DATA for associated CHECK CONDITIONS (24 or 26 bytes). This makes it difficult to send full SENSE DATA that can be up to 252 bytes. Implement MODE 2 responses which have us build the FCP Response in system memory which the ISP will put onto the wire directly. On the initiator side, the same problem occurs in that a command status response only has a limited amount of space for SENSE DATA. This data is supplemented by status continuation responses that the ISP pushes onto the response queue after the status response. We now pull them all together so that full sense data can be returned to the periph driver. This is supported on 23XX, 24XX and 25XX cards. This is also preparation for doing >16 byte CDBs. ----------- FC TAPE Implement full FC-TAPE on both initiator and target mode side. This capability is driven by firmware loaded, board type, board NVRAM settings, or hint configuration options to enable or disable. This is supported for 23XX, 24XX and 25XX cards. On the initiator side, we pretty much just have to generate a command reference number for each command we send out. This is FCP-4 compliant in that we do this per ITL nexus to generate the allowed 1 thru 255 CRN. In order to support the target side of FC-TAPE, we now pay attention to more of the PRLI word 3 parameters which will tell us whether an initiator wants confirmed responses.

isp_get_ctio2e(ispsoftc_t *isp, ct2e_entry_t *src, ct2e_entry_t *dst)
Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer. Devote a single bit to mboxbsy- and set aside bits for output mbox registers that we need to pick up- we can have at least one command which does not have any defined output registers (MBOX_EXECUTE_FIRMWARE).

----------- MISC CHANGES Add a new async event- ISP_TARGET_NOTIFY_ACK, that will guarantee eventual delivery of a NOTIFY ACK. This is tons better than just ignoring the return from isp_notify_ack and hoping for the best. Clean up the lower level lun enable code to be a bit more sensible. Fix a botch in isp_endcmd which was messing up the sense data. Fix notify ack for SRR to use a sensible error code in the case of a reject. Clean up and make clear what kind of firmware we've loaded and what capabilities it has. ----------- FULL (252 byte) SENSE DATA In CTIOs for the ISP, there's only a limimted amount of space to load SENSE DATA for associated CHECK CONDITIONS (24 or 26 bytes). This makes it difficult to send full SENSE DATA that can be up to 252 bytes. Implement MODE 2 responses which have us build the FCP Response in system memory which the ISP will put onto the wire directly. On the initiator side, the same problem occurs in that a command status response only has a limited amount of space for SENSE DATA. This data is supplemented by status continuation responses that the ISP pushes onto the response queue after the status response. We now pull them all together so that full sense data can be returned to the periph driver. This is supported on 23XX, 24XX and 25XX cards. This is also preparation for doing >16 byte CDBs. ----------- FC TAPE Implement full FC-TAPE on both initiator and target mode side. This capability is driven by firmware loaded, board type, board NVRAM settings, or hint configuration options to enable or disable. This is supported for 23XX, 24XX and 25XX cards. On the initiator side, we pretty much just have to generate a command reference number for each command we send out. This is FCP-4 compliant in that we do this per ITL nexus to generate the allowed 1 thru 255 CRN. In order to support the target side of FC-TAPE, we now pay attention to more of the PRLI word 3 parameters which will tell us whether an initiator wants confirmed responses. While we're at it, we'll pay attention to the initiator view too and report it. On sending back CTIOs, we will notice whether the initiator wants confirmed responses and we'll set up flags to do so. If a response or data frame is lost the initiator sends us an SRR (Sequence Retransmit Request) ELS which shows up as an SRR notify and all outstanding CTIOs are nuked with SRR Received status. The SRR notify contains the offset that the initiator wants us to restart the data transfer from or to retransmit the response frame. If the ISP driver still has the CCB around for which the data segment or response applies, it will retransmit. However, we typically don't know about a lost data frame until we send the FCP Response and the initiator totes up counters for data moved and notices missing segments. In this case we've already completed the data CCBs already and sent themn back up to the periph driver. Because there's no really clean mechanism yet in CAM to handle this, a hack has been put into place to complete the CTIO CCB with the CAM_MESSAGE_RECV status which will have a MODIFY DATA POINTER extended message in it. The internal ISP target groks this and ctl(8) will be modified to deal with this as well. At any rate, the data is retransmitted and an an FCP response is sent. The whole point here is to successfully complete a command so that you don't have to depend on ULP (SCSI) to have to recover, which in the case of tape is not really possible (hence the name FC-TAPE).

Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer. Devote a single bit to mboxbsy- and set aside bits for output mbox registers that we need to pick up- we can have at least one command which does not have any defined output registers (MBOX_EXECUTE_FIRMWARE).

Cheeze it a bit in that we have two DMA callback functions- one when we have bus_addr_t > 4 bits in width and the other which should be normal. Even Cheezier in that we turn off setting up DMA maps to be BUS_SPACE_MAXADDR if we're in ISP_TARGET_MODE.

Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer. Devote a single bit to mboxbsy- and set aside bits for output mbox registers that we need to pick up- we can have at least one command which does not have any defined output registers (MBOX_EXECUTE_FIRMWARE).

a) clean up some declaration stuff (i.e., make more modern with respect to getting rid u_int for uint and so on). b) Turn back on 64 bit DAC support. Cheeze it a bit in that we have two DMA callback functions- one when we have bus_addr_t > 4 bits in width and the other which should be normal. Even Cheezier in that we turn off setting up DMA maps to be BUS_SPACE_MAXADDR if we're in ISP_TARGET_MODE. More work on this in a week or so. c) Tested under amd64 and 1MB DFLTPHYS, sparc64, i386 (PAE, but insufficient memory to really test > 4GB). LINT check under amd64. MFC after: 1 month

ISP_IOXPUT_16(isp, src->in_oxid, &dst->in_oxid);
Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh.

This allows us to support the 2322 (and 2422 4Gb) cards which only come with the 2K Port Login firmware. The 2322 should now work- but we don't have firmware sets for it in ispfw (as the change to load 2K Port Login f/w hasn't been made- that f/w is so big it has to be loaded in more than one chunk). Other changes are the beginnings of cleaning up some long standing target mode issues. The next changes here will incorporate a lot of bug fixes from others.

Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer.

First of several commits as this driver is dusted off and maybe brought up to date. Principle changes for this reelase is to support 2K Port Login firmware. This allows us to support the 2322 (and 2422 4Gb) cards which only come with the 2K Port Login firmware. The 2322 should now work- but we don't have firmware sets for it in ispfw (as the change to load 2K Port Login f/w hasn't been made- that f/w is so big it has to be loaded in more than one chunk). Other changes are the beginnings of cleaning up some long standing target mode issues. The next changes here will incorporate a lot of bug fixes from others. Finally, some copyright cleanup and attempts to make the parts of the driver that are FreeBSD specific start conforming more to FreeBSD style. MFC after: 1 month
