* scsi: aacraid: stop using deprated get_seconds()Arnd Bergmann2018-06-261-2/+4
| | | | | | | | | | | | | | | | get_seconds() can overflow on 32-bit architectures and is deprecated because of that. The use in the aacraid driver has the same problem due to a limited firmware interface, it also overflows in the year 2106. This changes all calls to get_seconds() to the non-deprecated ktime_get_real_seconds(), which unfortunately doesn't solve that problem but gets rid of one user of the deprecated interface.

* scsi: aacraid: Perform initialization reset only onceGuilherme G. Piccoli2017-11-211-6/+14
| | | | | | | | | | | | | | | | | | | | | Currently the driver accepts two ways of requesting an initialization reset on the adapter: by passing aac_reset_devices module parameter, or the generic kernel parameter reset_devices. It's working as intended...but if we end up reaching a scsi hang and the scsi EH mechanism takes place, aacraid performs resets as part of the scsi error recovery procedure. These EH routines might reinitialize the device, and if we have provided some of the reset parameters in the kernel command-line, we again perform an "initialization" reset. So, to avoid this duplication of resets in case of scsi EH path, this patch adds a field to aac_dev struct to keep per-adapter track of the init reset request - once it's done, we set it to false and don't proactively reset anymore in case of reinitializations.

* scsi: aacraid: Add a small delay after IOP resetGuilherme G. Piccoli2017-09-281-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 0e9973ed3382 ("scsi: aacraid: Add periodic checks to see IOP reset status") changed the way driver checks if a reset succeeded. Now, after an IOP reset, aacraid immediately start polling a register to verify the reset is complete. This behavior cause regressions on the reset path in PowerPC (at least). Since the delay after the IOP reset was removed by the aforementioned patch, the fact driver just starts to read a register instantly after the reset was issued (by writing in another register) "corrupts" the reset procedure, which ends up failing all the time. The issue highly impacted kdump on PowerPC, since on kdump path we proactively issue a reset in adapter (through the reset_devices kernel parameter). This patch (re-)adds a delay right after IOP reset is issued. Empirically we measured that 3 seconds is enough, but for safety reasons we delay for 5s (and since it was 30s before, 5s is still a small amount). For reference, without this patch we observe the following messages on kdump kernel boot process: [ 76.294] aacraid 0003:01:00.0: IOP reset failed [ 76.294] aacraid 0003:01:00.0: ARC Reset attempt failed [ 86.524] aacraid 0003:01:00.0: adapter kernel panic'd ff.

| | | | | | | | | | | | | | | | | | | | | | | The driver utilizes an array of atomic variables to keep track of IO submissions to each vector. To submit an IO multiple threads iterate through the array to find a vector which has empty slots to send an IO. The reading and updating of the variable is not atomic, causing race conditions when a thread uses a full vector to submit an IO. Fixed by mapping each FIB to a vector, the submission path then uses said vector to submit IO thereby removing the possibly of a race condition.The vector assignment is started from 1 since vector 0 is reserved for the use of AIF management FIBS.If the number of MSIx vectors is 1 (MSI or INTx mode) then all the fibs are allocated to vector 0.

* aacraid: IOP RESET command handling changesMahesh Rajashekhara2015-04-101-9/+27
| | | | | | | | | | | | This patch fixes the IOP_RESET issue. Sending IOP_RESET command need to wait for only 10 sec instead of 5 minutes in case of firmware does not response IOP_RESET command. Disable interrupt before setup interrupt routine to prevent spurious interrupts.

* [SCSI] aacraid: Fix for arrays are going offline in the system. System hangsMahesh Rajashekhara2013-06-271-0/+3
| | | | | | | | | | | | | | | | | One of the customer had reported that the set of raid logical arrays will become unavailable (I/O offline) after a long hours of IO stress test. The OS wouldn`t be accessible afterwards and require a hard reset. This driver patch has a fix for race condition between the doorbell and the circular buffer. The driver is modified to do an extra read after clearing the doorbell in case there had been a completion posted during the small timing window. With this fix, we ran IO stress for ~13 days. There were no IO failures. Signed-off-by: Mahesh Rajashekhara <Mahesh.Rajashekhara@pmcs.com> Cc: <stable@vger.kernel.org> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

* [SCSI] aacraid: add an iounmap call to aac_src_ioremapTomas Henzl2012-04-231-0/+2
| | | | | | | | | | | | | | | The patch 116046127d1a3bad2853d02781ad9fee33f05e5a "[SCSI] aacraid: Added Sync.mode to support series 7/8/9 controllers" removed an iounmap call from aac_src_ioremap. Before that, the iounmap has been called twice with the same value (dev->base and dev->regs.src.bar0) and the iounmap complained about it (iounmap: bad address ...). The proper solution is a change the paremeter from bar0 to bar1. Fix this by adding a an iounmap(dev->regs.src.bar1) call.
