[SCSI] aacraid: Add new code for PMC-Sierra's SRC based controller family

2011-03-23T16:36:58Z

Added new hardware device 0x28b interface for PMC-Sierra's SRC based controller family. - new src.c file for 0x28b specific functions - new XPORT header required - sync. command interface: doorbell bits shifted (SRC_ODR_SHIFT, SRC_IDR_SHIFT) - async. Interface: different inbound queue handling, no outbound I2O queue available, using doorbell ("PmDoorBellResponseSent") and response buffer on the host ("host_rrq") for status - changed AIF (adapter initiated FIBs) interface: "DoorBellAifPending" bit to inform about pending AIF, "AifRequest" command to read AIF, "NoMoreAifDataAvailable" to mark the end of the AIFs Signed-off-by: Mahesh Rajashekhara Signed-off-by: James Bottomley

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h

2010-03-30T13:02:32Z

percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

drivers: Remove unnecessary inclusions of asm/semaphore.h

2008-04-19T02:16:32Z

None of these files use any of the functionality promised by asm/semaphore.h. It's possible that they rely on it dragging in some unrelated header file, but I can't build all these files, so we'll have fix any build failures as they come up. Signed-off-by: Matthew Wilcox

[SCSI] aacraid: add optional MSI support

2008-02-11T16:20:54Z

Added support for MSI utilizing the aacraid.msi=1 parameter. This patch adds some localized or like-minded janitor fixes. Since the default is disabled, there is no impact on the code paths unless the customer wishes to experiment with the MSI performance. Signed-off-by: Mark Salyzyn Signed-off-by: James Bottomley

[SCSI] aacraid: fix big endian issues

2008-01-23T17:29:19Z

Big endian systems issues discovered in the aacraid driver. Somewhat reverses a patch from November 7th of last year that removed swap operations because they formerly were being assigned to an u8 array when they should have been assigned to an le32 array. This patch is largely inert for any little endian processor architecture. It resolves a bug in delivering the BlinkLED AIF event to registered applications when the adapter or associated hardware was reset due to ill health. A rare corner case occurrence, also largely unnoticed by any as it was a new (untested!) feature. Signed-off-by: Mark Salyzyn Signed-off-by: James Bottomley

[SCSI] aacraid: forced reset override

2008-01-12T00:22:39Z

Some of our vendors have requested that our adapters ignore the hardware reset attempts during recovery and have enforced this with changes in Adapter Firmware. Some of our customers have requested the option to be able to reset the adapter under adverse adapter failure, we even had a few defects reported here considering it a regression that the Adapter could not be reset. This patch addresses this dichotomy. The user can force the adapter to be reset if it supports the IOP_RESET_ALWAYS command, in cases where the adapter has been programmed to ignore the reset, by setting the aacraid.check_reset parameter to a value of -1. The driver will not reset an Adapter that does not support the reset command(s). This patch also fixes and cleans up some of the logic associated with resetting the adapter.

[SCSI] aacraid: fix Sunrise Lake reset handling

2007-07-28T14:11:32Z

The patch is *much* smaller than the description. I am attempting to answer to those that want to understand an issue that was reported in May this year. If a Sunrise Lake based card that requires an alternate reset mechanism is set up to ignore the commanded IOP_RESET it reports 0x00000010 (IOP_RESET ignored) instead of 0x3803000F (use alternate reset mechanism to reset all cores), and thus the reset platform function decides to switch to IOP_RESET_ALWAYS because the reset platform function parameters indicate that we *need* to reset the card. IOP_RESET_ALWAYS then responds with the 0x3803000F return code, but alas we treat this as an error instead of using the alternate reset mechanism (put a 0x03 into the register offset 0x38). The reset fails, but the fact that the IOP_RESET_ALWAYS command was issued has put the card in a purposeful shutdown state in preparation for the alternate hardware reset to be applied. Yuck. IOP_RESET is ignored in internal production cards, typically to ensure that we catch all adapter lockup issues without the driver progressing further, so this would not appear to be a field issue and thus this patch was destined to be only in the internal Adaptec source tree. IOP_RESET_ALWAYS is reserved for kexec/kdump/FirmwareUpdate/AutomatedTestFrames so we did not function as expected in any case. Also in the past we have had OEMs specifically request that cards not be resetable after a BlinkLED/FirmwareAssert for one reason or another and To head off the possibility that the Sunrise Lake based cards would suffer a similar fate, we propose the enclosed fix. Yinghai Lu of SUN had a pre-production card with IOP_RESET disabled when he reported an issue to the linux kernel list back in May regarding a kexec problem resulting from this reset being ignore. His fix was to update the Firmware to one that did not ignore the IOP_RESET. Previous kernels did not attempt to reset the adapter and that is why it surfaced as a regression in his hands. The current list of aacraid based cards that use Sunrise Lake: 9005:0285:9005:02b5 Adaptec 5445 9005:0285:9005:02b6 Adaptec 5805 9005:0285:9005:02b7 Adaptec 5085 9005:0285:9005:02c3 Adaptec 51205 9005:0285:9005:02c4 Adaptec 51605 9005:0285:9005:02ce Adaptec 51245 9005:0285:9005:02cf Adaptec 51645 9005:0285:9005:02d0 Adaptec 52445 9005:0285:9005:02d1 Adaptec 5405 9005:0285:9005:02b8 ICP ICP5445SL 9005:0285:9005:02b9 ICP ICP5085SL 9005:0285:9005:02ba ICP ICP5805SL 9005:0285:9005:02c5 ICP ICP5125SL 9005:0285:9005:02c6 ICP ICP5165SL 9005:0285:108e:7aac SUN STK RAID REM 9005:0285:108e:0286 SUN STK RAID INT 9005:0285:108e:0287 SUN STK RAID EXT 9005:0285:108e:7aae SUN STK RAID EM All of these are publicly released with IOP_RESET enabled.
