Add support for the Qlogic ISP SCSI && FC/AL Adapters
1998-04-22 18:12:29 +00:00
*
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

Some rearrangement of headers to minimize diffs with outside of FreeBSD repository and to clean up the license header so as to not pollute the license with file function. Zero all mailbox structures prior to use (just in case). Change the outgoing mailbox count for INIT_FIRMWARE to be correct.

Convert isp(4) and ispfw(4) to use firmware(9) to manage firmware loading for the QLogic cards. Because isp(4) exists before the root is mounted, it's not really possible for us to use the kernel's linker to load modules directly from disk- that's really too bad. However, the this is still a net win in in that the firmware has been split up on a per chip (and in some cases, functionality) basis, so the amount of stuff loaded *can* be substantially less than the 1.5MB of firmware images that ispfw now manages. That is, each specific f/w set is now also built as a module. For example, QLogic 2322 f/w is built as isp_2322.ko and Initiator/Target 1080 firmware is built as isp_1080_it.ko. For compatibility purposes (i.e., to perturb folks the least), we also still build all of the firmware as one ispfw.ko module. This allows us to let 'ispfw_LOAD' keep on working in existing loader.conf files. If you now want to strip this down to just the firmware for your h/w, you can then change loader.conf to load the f/w you specifically want. We also still allow for ispfw to be statically built (e.g., for PAE and sparc64). Future changes will look at f/w unloading and also role switching that then uses the kernel linker to load different ips f/w sets. MFC after: 2 months

Clean up firmware load issues and remove darn near all config options. Force alphas to prefer mem mapping as the default. Basically, we have a pointer to a function which we can call which will return us a pointer to firmware for the card we have. We call this function (if it's non-NULL) with the address of our mdvec f/w pointer. The way this works is that if ispfw (as a module or a static) is loaded, it initializes the pointer in isp_pci, so we can call into to it to fetch a pointer to a f/w set. If ispfw is MOD_UNLOADed, it's retained a pointer to our mdvec f/w pointers, which then get zeroed out so we don't have any references to data that's now gone from kernel memory. Removing the f/w saves ~360KBytes. Alas, there is no autounload mechanism that works for is here.

Do various fixes to support firmware loading for the 2322 (and by extension, the 2422). One peculiar thing I've found with the 2322 is that if you don't force it to do Hard LoopID acquisition, the firmware crashes. This took a while to figure out. While we're at it, fix various bugs having to do with NVRAM reading and option setting with respect to pieces of NVRAM.

Clean up firmware load issues and remove darn near all config options. Force alphas to prefer mem mapping as the default. Basically, we have a pointer to a function which we can call which will return us a pointer to firmware for the card we have. We call this function (if it's non-NULL) with the address of our mdvec f/w pointer. The way this works is that if ispfw (as a module or a static) is loaded, it initializes the pointer in isp_pci, so we can call into to it to fetch a pointer to a f/w set. If ispfw is MOD_UNLOADed, it's retained a pointer to our mdvec f/w pointers, which then get zeroed out so we don't have any references to data that's now gone from kernel memory. Removing the f/w saves ~360KBytes. Alas, there is no autounload mechanism that works for is here.

Clean up firmware load issues and remove darn near all config options. Force alphas to prefer mem mapping as the default. Basically, we have a pointer to a function which we can call which will return us a pointer to firmware for the card we have. We call this function (if it's non-NULL) with the address of our mdvec f/w pointer. The way this works is that if ispfw (as a module or a static) is loaded, it initializes the pointer in isp_pci, so we can call into to it to fetch a pointer to a f/w set. If ispfw is MOD_UNLOADed, it's retained a pointer to our mdvec f/w pointers, which then get zeroed out so we don't have any references to data that's now gone from kernel memory. Removing the f/w saves ~360KBytes. Alas, there is no autounload mechanism that works for is here.

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

Convert isp(4) and ispfw(4) to use firmware(9) to manage firmware loading for the QLogic cards. Because isp(4) exists before the root is mounted, it's not really possible for us to use the kernel's linker to load modules directly from disk- that's really too bad. However, the this is still a net win in in that the firmware has been split up on a per chip (and in some cases, functionality) basis, so the amount of stuff loaded *can* be substantially less than the 1.5MB of firmware images that ispfw now manages. That is, each specific f/w set is now also built as a module. For example, QLogic 2322 f/w is built as isp_2322.ko and Initiator/Target 1080 firmware is built as isp_1080_it.ko. For compatibility purposes (i.e., to perturb folks the least), we also still build all of the firmware as one ispfw.ko module. This allows us to let 'ispfw_LOAD' keep on working in existing loader.conf files. If you now want to strip this down to just the firmware for your h/w, you can then change loader.conf to load the f/w you specifically want. We also still allow for ispfw to be statically built (e.g., for PAE and sparc64). Future changes will look at f/w unloading and also role switching that then uses the kernel linker to load different ips f/w sets. MFC after: 2 months

Eliminate the use of the getenv_int stuff we'd been using (with a bitmap for selecting unit). Instead, use the resource hints mechanism. One unfortunate situation here is that there is no resource_quad_value function- which is what I needed for WWN boot time replacement. Worse- you can't store the hint as just plain hint.isp.0.nodewwn="0x50000000aaaa0001" because this gets interpreted as an int- incorrectly because it can't be converted to an int. I can't even get this as a string. To work around this particular case for nodewwn && portwwn setting, this rather grotesque form will be used: hint.isp.0.nodewwn="w50000000aaaa0001" hint.isp.0.portwwn="w50000000aaaa0002" At the same time, if we have no hinted WWN, set the default WWN (which, btw, gets overridden if the card has valid NVRAM, which is usual) to 0x400000007F000009ull (which translates to NAA == IPv4, 127.0.0.9).

Eliminate the use of the getenv_int stuff we'd been using (with a bitmap for selecting unit). Instead, use the resource hints mechanism. One unfortunate situation here is that there is no resource_quad_value function- which is what I needed for WWN boot time replacement. Worse- you can't store the hint as just plain hint.isp.0.nodewwn="0x50000000aaaa0001" because this gets interpreted as an int- incorrectly because it can't be converted to an int. I can't even get this as a string. To work around this particular case for nodewwn && portwwn setting, this rather grotesque form will be used: hint.isp.0.nodewwn="w50000000aaaa0001" hint.isp.0.portwwn="w50000000aaaa0002" At the same time, if we have no hinted WWN, set the default WWN (which, btw, gets overridden if the card has valid NVRAM, which is usual) to 0x400000007F000009ull (which translates to NAA == IPv4, 127.0.0.9). Eliminate more printf's and replace them either with device_printf or isp_prt calls.

Clean up firmware load issues and remove darn near all config options. Force alphas to prefer mem mapping as the default. Basically, we have a pointer to a function which we can call which will return us a pointer to firmware for the card we have. We call this function (if it's non-NULL) with the address of our mdvec f/w pointer. The way this works is that if ispfw (as a module or a static) is loaded, it initializes the pointer in isp_pci, so we can call into to it to fetch a pointer to a f/w set. If ispfw is MOD_UNLOADed, it's retained a pointer to our mdvec f/w pointers, which then get zeroed out so we don't have any references to data that's now gone from kernel memory. Removing the f/w saves ~360KBytes. Alas, there is no autounload mechanism that works for is here.

Convert isp(4) and ispfw(4) to use firmware(9) to manage firmware loading for the QLogic cards. Because isp(4) exists before the root is mounted, it's not really possible for us to use the kernel's linker to load modules directly from disk- that's really too bad. However, the this is still a net win in in that the firmware has been split up on a per chip (and in some cases, functionality) basis, so the amount of stuff loaded *can* be substantially less than the 1.5MB of firmware images that ispfw now manages. That is, each specific f/w set is now also built as a module. For example, QLogic 2322 f/w is built as isp_2322.ko and Initiator/Target 1080 firmware is built as isp_1080_it.ko. For compatibility purposes (i.e., to perturb folks the least), we also still build all of the firmware as one ispfw.ko module. This allows us to let 'ispfw_LOAD' keep on working in existing loader.conf files. If you now want to strip this down to just the firmware for your h/w, you can then change loader.conf to load the f/w you specifically want. We also still allow for ispfw to be statically built (e.g., for PAE and sparc64). Future changes will look at f/w unloading and also role switching that then uses the kernel linker to load different ips f/w sets. MFC after: 2 months

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.

Eliminate the use of the getenv_int stuff we'd been using (with a bitmap for selecting unit). Instead, use the resource hints mechanism. One unfortunate situation here is that there is no resource_quad_value function- which is what I needed for WWN boot time replacement. Worse- you can't store the hint as just plain hint.isp.0.nodewwn="0x50000000aaaa0001" because this gets interpreted as an int- incorrectly because it can't be converted to an int. I can't even get this as a string. To work around this particular case for nodewwn && portwwn setting, this rather grotesque form will be used: hint.isp.0.nodewwn="w50000000aaaa0001" hint.isp.0.portwwn="w50000000aaaa0002" At the same time, if we have no hinted WWN, set the default WWN (which, btw, gets overridden if the card has valid NVRAM, which is usual) to 0x400000007F000009ull (which translates to NAA == IPv4, 127.0.0.9). Eliminate more printf's and replace them either with device_printf or isp_prt calls.

Clean up firmware load issues and remove darn near all config options. Force alphas to prefer mem mapping as the default. Basically, we have a pointer to a function which we can call which will return us a pointer to firmware for the card we have. We call this function (if it's non-NULL) with the address of our mdvec f/w pointer. The way this works is that if ispfw (as a module or a static) is loaded, it initializes the pointer in isp_pci, so we can call into to it to fetch a pointer to a f/w set. If ispfw is MOD_UNLOADed, it's retained a pointer to our mdvec f/w pointers, which then get zeroed out so we don't have any references to data that's now gone from kernel memory. Removing the f/w saves ~360KBytes. Alas, there is no autounload mechanism that works for is here.

Do various fixes to support firmware loading for the 2322 (and by extension, the 2422). One peculiar thing I've found with the 2322 is that if you don't force it to do Hard LoopID acquisition, the firmware crashes. This took a while to figure out. While we're at it, fix various bugs having to do with NVRAM reading and option setting with respect to pieces of NVRAM.

For compatibility purposes (i.e., to perturb folks the least), we also still build all of the firmware as one ispfw.ko module. This allows us to let 'ispfw_LOAD' keep on working in existing loader.conf files. If you now want to strip this down to just the firmware for your h/w, you can then change loader.conf to load the f/w you specifically want. We also still allow for ispfw to be statically built (e.g., for PAE and sparc64). Future changes will look at f/w unloading and also role switching that then uses the kernel linker to load different ips f/w sets. MFC after: 2 months

Clean up firmware load issues and remove darn near all config options. Force alphas to prefer mem mapping as the default. Basically, we have a pointer to a function which we can call which will return us a pointer to firmware for the card we have. We call this function (if it's non-NULL) with the address of our mdvec f/w pointer. The way this works is that if ispfw (as a module or a static) is loaded, it initializes the pointer in isp_pci, so we can call into to it to fetch a pointer to a f/w set. If ispfw is MOD_UNLOADed, it's retained a pointer to our mdvec f/w pointers, which then get zeroed out so we don't have any references to data that's now gone from kernel memory. Removing the f/w saves ~360KBytes. Alas, there is no autounload mechanism that works for is here.

Do various fixes to support firmware loading for the 2322 (and by extension, the 2422). One peculiar thing I've found with the 2322 is that if you don't force it to do Hard LoopID acquisition, the firmware crashes. This took a while to figure out. While we're at it, fix various bugs having to do with NVRAM reading and option setting with respect to pieces of NVRAM.

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

Clean up firmware load issues and remove darn near all config options. Force alphas to prefer mem mapping as the default. Basically, we have a pointer to a function which we can call which will return us a pointer to firmware for the card we have. We call this function (if it's non-NULL) with the address of our mdvec f/w pointer. The way this works is that if ispfw (as a module or a static) is loaded, it initializes the pointer in isp_pci, so we can call into to it to fetch a pointer to a f/w set. If ispfw is MOD_UNLOADed, it's retained a pointer to our mdvec f/w pointers, which then get zeroed out so we don't have any references to data that's now gone from kernel memory. Removing the f/w saves ~360KBytes. Alas, there is no autounload mechanism that works for is here.

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

add a newbus method for obtaining the bus's bus_dma_tag_t... This is required by arches like sparc64 (not yet implemented) and sun4v where there are seperate IOMMU's for each PCI bus... For all other arches, it will end up returning NULL, which makes it a no-op... Convert a few drivers (the ones we've been working w/ on sun4v) to the new convection... Eventually all drivers will need to replace the parent tag of NULL, w/ bus_get_dma_tag(dev), though dev is usually different for each driver, and will require hand inspection...

A major amount of cleaning up: + Change some messages about CCB memory allocation + Turn a failure to DMA map all of a transaction due to lack of ISP queue entries into a requeue operation (instead of the case where it had been treated the same as a DMA too big operation). + put back splsoftvm around bus_dmamap_load calls. + cleanup (and fix a glaring bug) in the and of the dma setup routine. Also, the dma setup routines either return CMD_QUEUED (for success) or CMD_COMPLETE (for failure) or CMD_EAGAIN (for requeuing for resource shortage reasons).

Complete some Ansification. Check to make sure, in tdma_mk, that we won't overflow the request queue. The reason we want to do this is that we now push out completed CTIOs as we complete them- this gets the QLogic working on them quicker. So we need to know whether we can put the entire burrito out before we start. We now support conjoint status with data for the last CTIO for both Fibre Channel and SCSI. Leave the old code in place in case we need to go back (minor 3 line ifdef). Ultra-ultra important- *don't* set rq->req_seg_count for non-data target mode requests in isp_pci_dmasetup. D'oh- this is actually the tag value area for a CTIO. What *was* I thinking? Boy howdy does both aic7xxx and sym get awfully unhappy when on reconnect you give them a constant '1' for a tag value.

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.

For parallel SCSI, let us now do status with the final CTIO. For the 1080, I was hanging after sending a xfer CTIO and a status CTIO for a non-discon INQUIRY- the xfer CTIO was returned as completed OK, but the status CTIO was dropped on the floor. All the fields looked good. I don't know why it got dropped. But allowing status to go back with data xfer seemed to work. I also noticed that with a non-disconnecting command that the firmware handle in the ATIO is zero- this leads me to believe that the f/w really can only handle one CTIO at a time in the discon case, and it had no idea what to do with the second (status) CTIO.

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.

Switch to using 16 bit handles instead of 32 bit handles. This is a pretty invasive change, but there are three good reasons to do this: 1. We'll never have > 16 bits of handle. 2. We can (eventually) enable the RIO (Reduced Interrupt Operation) bits which return multiple completing 16 bit handles in mailbox registers. 3. The !)$*)$*~)@$*~)$* Qlogic target mode for parallel SCSI spec changed such that at_reserved (which was 32 bits) was split into two pieces- and one of which was a 16 bit handle id that functions like the at_rxid for Fibre Channel (a tag for the f/w to correlate CTIOs with a particular command). Since we had to muck with that and this changed the whole handler architecture, we might as well... Propagate new at_handle on through int ct_fwhandle. Follow implications of changing to 16 bit handles. These above changes at least get Qlogic 1040 cards working in target mode again. 1080/12160 cards don't work yet.

For parallel SCSI, let us now do status with the final CTIO. For the 1080, I was hanging after sending a xfer CTIO and a status CTIO for a non-discon INQUIRY- the xfer CTIO was returned as completed OK, but the status CTIO was dropped on the floor. All the fields looked good. I don't know why it got dropped. But allowing status to go back with data xfer seemed to work. I also noticed that with a non-disconnecting command that the firmware handle in the ATIO is zero- this leads me to believe that the f/w really can only handle one CTIO at a time in the discon case, and it had no idea what to do with the second (status) CTIO.

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

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.

Switch to using 16 bit handles instead of 32 bit handles. This is a pretty invasive change, but there are three good reasons to do this: 1. We'll never have > 16 bits of handle. 2. We can (eventually) enable the RIO (Reduced Interrupt Operation) bits which return multiple completing 16 bit handles in mailbox registers. 3. The !)$*)$*~)@$*~)$* Qlogic target mode for parallel SCSI spec changed such that at_reserved (which was 32 bits) was split into two pieces- and one of which was a 16 bit handle id that functions like the at_rxid for Fibre Channel (a tag for the f/w to correlate CTIOs with a particular command). Since we had to muck with that and this changed the whole handler architecture, we might as well... Propagate new at_handle on through int ct_fwhandle. Follow implications of changing to 16 bit handles. These above changes at least get Qlogic 1040 cards working in target mode again. 1080/12160 cards don't work yet.

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. 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).

uint16_t onxti;
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.

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

Eliminate the use of the getenv_int stuff we'd been using (with a bitmap for selecting unit). Instead, use the resource hints mechanism. One unfortunate situation here is that there is no resource_quad_value function- which is what I needed for WWN boot time replacement. Worse- you can't store the hint as just plain hint.isp.0.nodewwn="0x50000000aaaa0001" because this gets interpreted as an int- incorrectly because it can't be converted to an int. I can't even get this as a string. To work around this particular case for nodewwn && portwwn setting, this rather grotesque form will be used: hint.isp.0.nodewwn="w50000000aaaa0001" hint.isp.0.portwwn="w50000000aaaa0002" At the same time, if we have no hinted WWN, set the default WWN (which, btw, gets overridden if the card has valid NVRAM, which is usual) to 0x400000007F000009ull (which translates to NAA == IPv4, 127.0.0.9).

A major amount of cleaning up: + Change some messages about CCB memory allocation + Turn a failure to DMA map all of a transaction due to lack of ISP queue entries into a requeue operation (instead of the case where it had been treated the same as a DMA too big operation). + put back splsoftvm around bus_dmamap_load calls. + cleanup (and fix a glaring bug) in the and of the dma setup routine. Also, the dma setup routines either return CMD_QUEUED (for success) or CMD_COMPLETE (for failure) or CMD_EAGAIN (for requeuing for resource shortage reasons).

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).

Do the small amount of tweaking to support PAE for at least initiator mode. I was unable to test this as the PAE kernel crashed with a "cannot copy LDT" before coming up. When this gets a bit more testing, I'll fix the PAE conf file to allow isp devices. PR: 59728

if (msg)
Eliminate the use of the getenv_int stuff we'd been using (with a bitmap for selecting unit). Instead, use the resource hints mechanism. One unfortunate situation here is that there is no resource_quad_value function- which is what I needed for WWN boot time replacement. Worse- you can't store the hint as just plain hint.isp.0.nodewwn="0x50000000aaaa0001" because this gets interpreted as an int- incorrectly because it can't be converted to an int. I can't even get this as a string. To work around this particular case for nodewwn && portwwn setting, this rather grotesque form will be used: hint.isp.0.nodewwn="w50000000aaaa0001" hint.isp.0.portwwn="w50000000aaaa0002" At the same time, if we have no hinted WWN, set the default WWN (which, btw, gets overridden if the card has valid NVRAM, which is usual) to 0x400000007F000009ull (which translates to NAA == IPv4, 127.0.0.9). Eliminate more printf's and replace them either with device_printf or isp_prt calls.
