2016-04-30aacraid: Fix for KDUMP driver hangRaghava Aditya Renukunta1-0/+24
When KDUMP is triggered the driver first talks to the firmware in INTX mode, but the adapter firmware is still in MSIX mode. Therefore the first driver command hangs since the driver is waiting for an INTX response and firmware gives a MSIX response. If when the OS is installed on a RAID drive created by the adapter KDUMP will hang since the driver does not receive a response in sync mode. Fixed by: Change the firmware to INTX mode if it is in MSIX mode before sending the first sync command.

2010-01-17[SCSI] aacraid: fix File System going into read-only modePenchala Narasimha Reddy Chilakala, ERS-HCLTech1-1/+5
These particular problems were reported by Cisco and SAP and customers as well. Cisco reported on RHEL4 U6 and SAP reported on SLES9 SP4 and SLES10 SP2. We added these fixes on RHEL4 U6 and gave a private build to IBM and Cisco. Cisco and IBM tested it for more than 15 days and they reported that they did not see the issue so far. Before the fix, Cisco used to see the issue within 5 days. We generated a patch for SLES9 SP4 and SLES10 SP2 and submitted to Novell. Novell applied the patch and gave a test build to SAP. SAP tested and reported that the build is working properly. We also tested in our lab using the tools "dishogsync", which is IO stress tool and the tool was provided by Cisco. Issue1: File System going into read-only mode Root cause: The driver tends to not free the memory (FIB) when the management request exits prematurely. The accumulation of such un-freed memory causes the driver to fail to allocate anymore memory (FIB) and hence return 0x70000 value to the upper layer, which puts the file system into read only mode. Fix details: The fix makes sure to free the memory (FIB) even if the request exits prematurely hence ensuring the driver wouldn't run out of memory (FIBs). Issue2: False Raid Alert occurs When the Physical Drives and Logical drives are reported as deleted or added, even though there is no change done on the system Root cause: Driver IOCTLs is signaled with EINTR while waiting on response from the lower layers. Returning "EINTR" will never initiate internal retry. Fix details: The issue was fixed by replacing "EINTR" with "ERESTARTSYS" for mid-layer retries.

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.

For another, it confuses the fsck out of sparse. Use unsigned long or uintptr_t instead. There are several places misusing ptrdiff_t; fixed.

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau1-1/+0
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

Received from Mark Salyzyn from Adaptec. In the rare instances where the adapter, or the motherboard, is misbehaving; driver initialization or shutdown becomes problematic. By introducing a 3 minute timeout on the first interrupt driven command during initialization, or the issuance of the adapter shutdown command during driver unload, we can resolve the lockup problems induced by common (but rare) hardware misbehaviors. The timeout during initialization, should it occur, is accompanied by a message presented to the console and the logs indicating that the user should inspect and resolve problems with interrupt routing.

Received from Mark Salyzyn from Adaptec: If more than two commands are outstanding to the controller, there is no need to notify the adapter via a PCI bus transaction of additional commands added into the queue; it will get to them when it works through the produce/consumer indexes. This reduced the PCI traffic in the driver to submit a command to the queue to near zero allowing a significant number of commands to be turned around with no need to block for the PCI bridge to flush the notify request to the adapter. Interrupt mitigation has always been present in the driver; it was turned off because of a bug that prevented one from realizing the usefulness of the feature. This bug is fixed in this patch.

I believe that other than the few small cleanups mentioned, that the changes are all related. - Added Variable FIB size negotiation for new adapters. - Added support to maximize scatter gather tables and thus permit requests larger than 64KB/each. - Limit Scatter Gather to 34 elements for ROMB platforms. - aac_printf is only enabled with AAC_QUIRK_34SG - Large FIB ioctl support - some minor cleanup Passes sparse check. I have tested it on x86 and ppc64 machines. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-05-20[SCSI] aacraid: remove sparse warningsMark Haverkamp1-2/+2
This patch addresses the sparse -Wbitwise warnings that Christoph wanted me to eliminate. This mostly consisted of making data structure elements of hardware associated structures the __le* equivalent. Although there were a couple places where there was mixing of cpu and le variable math. These changes have been tested on both an x86 and ppc machine running bonnie++. The usage of the LE32_ALL_ONES macro has been eliminated.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
