----------- 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).

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).

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).

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.

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.

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).

isp_put_extended_request(ispsoftc_t *isp, ispextreq_t *src, ispextreq_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.

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).

isp_get_24xx_abrt(ispsoftc_t *isp, isp24xx_abrt_t *src, isp24xx_abrt_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).

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_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).

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).

----------- 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.

----------- 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.

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.

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).

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.

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).

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).

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).

----------- 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).

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.

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. 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).

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.
