Add a driver for the new LSI MegaRAID SAS controller family. The 'MFI' name is derived from the phrase 'MegaRAID Firmware Interface' used by LSI. This driver provides a block interface to logical disks on the card and a minimal management device. It is MPSAFE, INTR_FAST, and 64-bit capable. Thanks to Dell for providing hardware to test with and IronPort for sponsoring the work. Sponsored by: Dell, Ironport MFC After: 3 days

First cut at updating mfi(4) to support newer LSI MegaRAID SAS cards. Specifically, add support for "Drake Skinny" and "ThunderBolt" LSI cards. Initial code was supplied by LSI under BSD license. Several improvements were done by myself. Such things like making it work in a static kernel, be able to boot of the RAID, performance improvements. I removed some fairly complicated code that seemed to directly access the disks under the firmware. It doesn't seem to be needed and significantly slowed down the performance of the driver and caused tons of sense errors to be reported. This code is being checked in this area so others can help me get it into shape to commit into the FreeBSD tree. Assistance has been volunteered by iXsystems. We might want to re-work the JBOD attachment that creates /dev/mfisyspd? node for each disk. Performance is faster then prior cards. It works okay with WITNESS and INVARIANTS on amd64 and i386. I recall seeing a use after free time bug with FreeBSD 8 and a Drake Skinny card with WITNESS and INVARIANTS on. First task is get all of the new structures to be named in FreeBSD style format. Next is probably to deal with the 64bit addressing changes that are mostly around the #ifdef __amd64__ checks. Thanks to LSI for providing the initial code. Obtained from: LSI

Add in a couple of things: - In the ioctl path let command get queued up and return when complete _without_ blocking the driving waiting for the response. This way the driver doesn't "lock up" for ~30s during a flash command. Submitted by scottl. - Add a guard so that if a DCMD of 0 is sent down the ioctl path don't send it to the controller. Return with a status of OK. This is a little strange since MegaCli doesn't seem to like something and will issue some DCMD of 0. This doesn't happen under Linux. So the emulation needs to be improved but I'm not sure what. Another strange thing is that when a DCMD of 0 gets issued under i386 the controller returns OK but in amd64 the context is messed up. - Add a guard so the context has to be with-in the legal limit so we get a reasonable error assertion versus random panic. It's going to be a challenge to figure out why MegaCli is not totally happy and then sends some bogus commands. This means that flashing firmware via the Linux tool won't work since it generates a DCMD of 0 when it should be opening the firmware for a flash update. Without this problem flashing works fine. This means there is no publicly available tool to upgrade the RAID firmware under FreeBSD right now. I plan to MFC all of the mfi changes to 6.X shortly. This might not include the SCSI pass-through changes. Submitted by: scottl Reviewed by: scottl MFC after: 3 days

TAILQ_ENTRY(mfi_system_pd) pd_link;
First cut at updating mfi(4) to support newer LSI MegaRAID SAS cards. Specifically, add support for "Drake Skinny" and "ThunderBolt" LSI cards. Initial code was supplied by LSI under BSD license. Several improvements were done by myself. Such things like making it work in a static kernel, be able to boot of the RAID, performance improvements. I removed some fairly complicated code that seemed to directly access the disks under the firmware. It doesn't seem to be needed and significantly slowed down the performance of the driver and caused tons of sense errors to be reported. This code is being checked in this area so others can help me get it into shape to commit into the FreeBSD tree. Assistance has been volunteered by iXsystems. We might want to re-work the JBOD attachment that creates /dev/mfisyspd? node for each disk. Performance is faster then prior cards. It works okay with WITNESS and INVARIANTS on amd64 and i386. I recall seeing a use after free time bug with FreeBSD 8 and a Drake Skinny card with WITNESS and INVARIANTS on. First task is get all of the new structures to be named in FreeBSD style format. Next is probably to deal with the 64bit addressing changes that are mostly around the #ifdef __amd64__ checks. Thanks to LSI for providing the initial code. Obtained from: LSI

Add in a bunch of things to the mfi driver: - Linux ioctl support, with the other Linux changes MegaCli will run if you mount linprocfs & linsysfs then set sysctl compat.linux.osrelease=2.6.12 or similar. This works on i386. It should work on amd64 but not well tested yet. StoreLib may or may not work. Remember to kldload mfi_linux. - Add in AEN (Async Event Notification) support so we can get messages from the firmware when something happens. Not all messages are in defined in event detail. Use event_log to try to figure out what happened. - Try to implement something like SIGIO for StoreLib. Since mrmonitor doesn't work right I can't fully test it. StoreLib works best with the rh9 base. In theory mrmonitor isn't needed due to native driver support of AEN :-) Now we can configure and monitor the RAID better. Submitted by: IronPort Systems.

First cut at updating mfi(4) to support newer LSI MegaRAID SAS cards. Specifically, add support for "Drake Skinny" and "ThunderBolt" LSI cards. Initial code was supplied by LSI under BSD license. Several improvements were done by myself. Such things like making it work in a static kernel, be able to boot of the RAID, performance improvements. I removed some fairly complicated code that seemed to directly access the disks under the firmware. It doesn't seem to be needed and significantly slowed down the performance of the driver and caused tons of sense errors to be reported. This code is being checked in this area so others can help me get it into shape to commit into the FreeBSD tree. Assistance has been volunteered by iXsystems. We might want to re-work the JBOD attachment that creates /dev/mfisyspd? node for each disk. Performance is faster then prior cards. It works okay with WITNESS and INVARIANTS on amd64 and i386. I recall seeing a use after free time bug with FreeBSD 8 and a Drake Skinny card with WITNESS and INVARIANTS on. First task is get all of the new structures to be named in FreeBSD style format. Next is probably to deal with the 64bit addressing changes that are mostly around the #ifdef __amd64__ checks. Thanks to LSI for providing the initial code. Obtained from: LSI

First fix pr 167226: ThunderBolt cannot read sector >= 2^32 or 2^21 with supplied patch. Second the bigger change, fix RAID operation on ThunderBolt base card such as physically removing a disk from a RAID and replacing it. The current situation is the RAID firmware effectively hangs waiting for an acknowledgement from the driver. This is due to the firmware support of the driver actually accessing the RAID from under the firmware. This is an interesting feature that the FreeBSD driver does not use. However, when the firmare detects the driver has attached it then expects the driver will synchronize LD's with the firmware. If the driver does not sync. then the management part of the firmware will hang waiting for it so a pulled driver will listed as still there. The fix for this problem isn't extremely difficult. However, figuring out why some of the code was the way it was and then redoing it was involved. Not have a spec. made it harder to try to figure out. The existing driver would send a MFI_DCMD_LD_MAP_GET_INFO command in write mode to acknowledge a LD state change. In read mode it gets the RAID map from the firmware. The FreeBSD driver doesn't do that currently. It could be added in the future with the appropriate structures. To simplify things, get the current LD state and then build the MFI_DCMD_LD_MAP_GET_INFO/write command so that it sends an acknowledgement for each LD. The map would probably state which LD's changed so then the driver could probably just acknowledge the LD's that changed versus all. This doesn't seem to be a problem. When a MFI_DCMD_LD_MAP_GET_INFO/write command is sent to the firmware, it will complete later when a change to the LD's happen. So it is very much like an AEN command returning when something happened. When the MFI_DCMD_LD_MAP_GET_INFO/write command completes, we refire the sync'ing of the LD state. This needs to be done in as an event so that MFI_DCMD_LD_GET_LIST can wait for that command to complete before issuing the MFI_DCMD_LD_MAP_GET_INFO/write. The prior code didn't use the call-back function and tried to intercept the MFI_DCMD_LD_MAP_GET_INFO/write command when processing an interrupt. This added a bunch of code complexity to the interrupt handler. Using the call-back that is done for other commands got rid of this need. So the interrupt handler is greatly simplified. It seems that even commands that shouldn't be acknowledged end up in the interrupt handler. To deal with this, code was added to check to see if a command is in the busy queue or not. This might have contributed to the interrupt storm happening without MSI enabled on these cards. Note that MFI_DCMD_LD_MAP_GET_INFO/read returns right away. It would be interesting to see what other complexity could be removed from the ThunderBolt driver that really isn't needed in our mode of operation. Letting the RAID firmware do all of the I/O to disks is a lot faster since it can use its caches. It greatly simplifies what the driver has to do and potential bugs if the driver and firmware are not in sync. Simplify the aen_abort/cm_map_abort and put it in the softc versus in the command structure. This should get merged to 9 before the driver is merged to 8.

/* OCR flags */
First cut at updating mfi(4) to support newer LSI MegaRAID SAS cards. Specifically, add support for "Drake Skinny" and "ThunderBolt" LSI cards. Initial code was supplied by LSI under BSD license. Several improvements were done by myself. Such things like making it work in a static kernel, be able to boot of the RAID, performance improvements. I removed some fairly complicated code that seemed to directly access the disks under the firmware. It doesn't seem to be needed and significantly slowed down the performance of the driver and caused tons of sense errors to be reported. This code is being checked in this area so others can help me get it into shape to commit into the FreeBSD tree. Assistance has been volunteered by iXsystems. We might want to re-work the JBOD attachment that creates /dev/mfisyspd? node for each disk. Performance is faster then prior cards. It works okay with WITNESS and INVARIANTS on amd64 and i386. I recall seeing a use after free time bug with FreeBSD 8 and a Drake Skinny card with WITNESS and INVARIANTS on. First task is get all of the new structures to be named in FreeBSD style format. Next is probably to deal with the 64bit addressing changes that are mostly around the #ifdef __amd64__ checks. Thanks to LSI for providing the initial code. Obtained from: LSI

First cut at updating mfi(4) to support newer LSI MegaRAID SAS cards. Specifically, add support for "Drake Skinny" and "ThunderBolt" LSI cards. Initial code was supplied by LSI under BSD license. Several improvements were done by myself. Such things like making it work in a static kernel, be able to boot of the RAID, performance improvements. I removed some fairly complicated code that seemed to directly access the disks under the firmware. It doesn't seem to be needed and significantly slowed down the performance of the driver and caused tons of sense errors to be reported. This code is being checked in this area so others can help me get it into shape to commit into the FreeBSD tree. Assistance has been volunteered by iXsystems. We might want to re-work the JBOD attachment that creates /dev/mfisyspd? node for each disk. Performance is faster then prior cards. It works okay with WITNESS and INVARIANTS on amd64 and i386. I recall seeing a use after free time bug with FreeBSD 8 and a Drake Skinny card with WITNESS and INVARIANTS on. First task is get all of the new structures to be named in FreeBSD style format. Next is probably to deal with the 64bit addressing changes that are mostly around the #ifdef __amd64__ checks. Thanks to LSI for providing the initial code. Obtained from: LSI

MFhead_mfi r227068 First cut of new HW support from LSI and merge into FreeBSD. Supports Drake Skinny and ThunderBolt cards. MFhead_mfi r227574 Style MFhead_mfi r227579 Use bus_addr_t instead of uintXX_t. MFhead_mfi r227580 MSI support MFhead_mfi r227612 More bus_addr_t and remove "#ifdef __amd64__". MFhead_mfi r227905 Improved timeout support from Scott. MFhead_mfi r228108 Make file. MFhead_mfi r228208 Fixed botched merge of Skinny support and enhanced handling in call back routine. MFhead_mfi r228279 Remove superfluous !TAILQ_EMPTY() checks before TAILQ_FOREACH(). MFhead_mfi r228310 Move mfi_decode_evt() to taskqueue. MFhead_mfi r228320 Implement MFI_DEBUG for 64bit S/G lists. MFhead_mfi r231988 Restore structure layout by reverting the array header to use [0] instead of [1]. MFhead_mfi r232412 Put wildcard pattern later in the match table. MFhead_mfi r232413 Use lower case for hexadecimal numbers to match surrounding style. MFhead_mfi r232414 Add more Thunderbolt variants. MFhead_mfi r232888 Don't act on events prior to boot or when shutting down. Add hw.mfi.detect_jbod_change to enable or disable acting on JBOD type of disks being added on insert and removed on removing. Switch hw.mfi.msi to 1 by default since it works better on newer cards. MFhead_mfi r233016 Release driver lock before taking Giant when deleting children. Use TAILQ_FOREACH_SAFE when items can be deleted. Make code a little simplier to follow. Fix a couple more style issues. MFhead_mfi r233620 Update mfi_spare/mfi_array with the actual number of elements for array_ref and pd. Change these max. #define names to avoid name space collisions. This will require an update to mfiutil It avoids mfiutil having to do a magic calculation. Add a note and #define to state that a "SYSTEM" disk is really what the firmware calls a "JBOD" drive.

First fix pr 167226: ThunderBolt cannot read sector >= 2^32 or 2^21 with supplied patch. Second the bigger change, fix RAID operation on ThunderBolt base card such as physically removing a disk from a RAID and replacing it. The current situation is the RAID firmware effectively hangs waiting for an acknowledgement from the driver. This is due to the firmware support of the driver actually accessing the RAID from under the firmware. This is an interesting feature that the FreeBSD driver does not use. However, when the firmare detects the driver has attached it then expects the driver will synchronize LD's with the firmware. If the driver does not sync. then the management part of the firmware will hang waiting for it so a pulled driver will listed as still there. The fix for this problem isn't extremely difficult. However, figuring out why some of the code was the way it was and then redoing it was involved. Not have a spec. made it harder to try to figure out. The existing driver would send a MFI_DCMD_LD_MAP_GET_INFO command in write mode to acknowledge a LD state change. In read mode it gets the RAID map from the firmware. The FreeBSD driver doesn't do that currently. It could be added in the future with the appropriate structures. To simplify things, get the current LD state and then build the MFI_DCMD_LD_MAP_GET_INFO/write command so that it sends an acknowledgement for each LD. The map would probably state which LD's changed so then the driver could probably just acknowledge the LD's that changed versus all. This doesn't seem to be a problem. When a MFI_DCMD_LD_MAP_GET_INFO/write command is sent to the firmware, it will complete later when a change to the LD's happen. So it is very much like an AEN command returning when something happened. When the MFI_DCMD_LD_MAP_GET_INFO/write command completes, we refire the sync'ing of the LD state. This needs to be done in as an event so that MFI_DCMD_LD_GET_LIST can wait for that command to complete before issuing the MFI_DCMD_LD_MAP_GET_INFO/write. The prior code didn't use the call-back function and tried to intercept the MFI_DCMD_LD_MAP_GET_INFO/write command when processing an interrupt. This added a bunch of code complexity to the interrupt handler. Using the call-back that is done for other commands got rid of this need. So the interrupt handler is greatly simplified. It seems that even commands that shouldn't be acknowledged end up in the interrupt handler. To deal with this, code was added to check to see if a command is in the busy queue or not. This might have contributed to the interrupt storm happening without MSI enabled on these cards. Note that MFI_DCMD_LD_MAP_GET_INFO/read returns right away. It would be interesting to see what other complexity could be removed from the ThunderBolt driver that really isn't needed in our mode of operation. Letting the RAID firmware do all of the I/O to disks is a lot faster since it can use its caches. It greatly simplifies what the driver has to do and potential bugs if the driver and firmware are not in sync. Simplify the aen_abort/cm_map_abort and put it in the softc versus in the command structure. This should get merged to 9 before the driver is merged to 8.

First cut at updating mfi(4) to support newer LSI MegaRAID SAS cards. Specifically, add support for "Drake Skinny" and "ThunderBolt" LSI cards. Initial code was supplied by LSI under BSD license. Several improvements were done by myself. Such things like making it work in a static kernel, be able to boot of the RAID, performance improvements. I removed some fairly complicated code that seemed to directly access the disks under the firmware. It doesn't seem to be needed and significantly slowed down the performance of the driver and caused tons of sense errors to be reported. This code is being checked in this area so others can help me get it into shape to commit into the FreeBSD tree. Assistance has been volunteered by iXsystems. We might want to re-work the JBOD attachment that creates /dev/mfisyspd? node for each disk. Performance is faster then prior cards. It works okay with WITNESS and INVARIANTS on amd64 and i386. I recall seeing a use after free time bug with FreeBSD 8 and a Drake Skinny card with WITNESS and INVARIANTS on. First task is get all of the new structures to be named in FreeBSD style format.

Separate the parallel scsi knowledge out of the core of the XPT, and modularize it so that new transports can be created. Add a transport for SATA Add a periph+protocol layer for ATA Add a driver for AHCI-compliant hardware. Add a maxio field to CAM so that drivers can advertise their max I/O capability. Modify various drivers so that they are insulated from the value of MAXPHYS. The new ATA/SATA code supports AHCI-compliant hardware, and will override the classic ATA driver if it is loaded as a module at boot time or compiled into the kernel. The stack now support NCQ (tagged queueing) for increased performance on modern SATA drives. It also supports port multipliers. ATA drives are accessed via 'ada' device nodes. ATAPI drives are accessed via 'cd' device nodes. They can all be enumerated and manipulated via camcontrol, just like SCSI drives. SCSI commands are not translated to their ATA equivalents; ATA native commands are used throughout the entire stack, including camcontrol. See the camcontrol manpage for further details. Testing this code may require that you update your fstab, and possibly modify your BIOS to enable AHCI functionality, if available. This code is very experimental at the moment. The userland ABI/API has changed, so applications will need to be recompiled. It may change further in the near future. The 'ada' device name may also change as more infrastructure is completed in this project. The goal is to eventually put all CAM busses and devices until newbus, allowing for interesting topology and management options. Few functional changes will be seen with existing SCSI/SAS/FC drivers, though the userland ABI has still changed. In the future, transports specific modules for SAS and FC may appear in order to better support the topologies and capabilities of these technologies. The modularization of CAM and the addition of the ATA/SATA modules is meant to break CAM out of the mold of being specific to SCSI, letting it grow to be a framework for arbitrary transports and protocols. It also allows drivers to be written to support discrete hardware without jeopardizing the stability of non-related hardware. While only an AHCI driver is provided now, a Silicon Image driver is also in the works. Drivers for ICH1-4, ICH5-6, PIIX, classic IDE, and any other hardware is possible and encouraged. Help with new transports is also encouraged. Submitted by: scottl, mav Approved by: re
