This patch adds a "pci_bus_reset" option to the board_mode sysfs attribute. This option uses the pci_reset_bus() api to reset the PCIe link the adapter is on, which will reset the chip/adapter. Prior to issuing this option, all functions on the same chip must be placed in the offline state by the admin. After the reset, all of the instances may be brought online again. The primary purpose of this functionality is to support cases where firmware update required a chip reset but the admin did not want to reboot the machine in order to instantiate the firmware update. Sanity checks take place prior to the reset to ensure the adapter is the sole entity on the PCIe bus and that all functions are in the offline state. Signed-off-by:

When a target's link dropped, an RSCN was received to communicate the change. The driver detected the loss of the target and issued and UNREG_RPI mailbox command. While that was being processed, another RSCN was received to communicate the port coming back. The driver deferred the PLOGI to the port until the mailbox command finishes. When the mailbox command completed it saw the pending port and called the routines to issue the PLOGI. However, it forgot to clear the UNREG_INP state flag, so the PLOGI xmt routine nooped the PLOGI request assuming it needed to wait for the mailbox command. At this point, login would never be re-attempted. Clear UNREG_INP before issuing the deferred PLOGI. Signed-off-by:

Currently, when a trunk link goes down due to some fault, the driver snapshots the fault code. If the link then comes back up, meaning there is no fault, the driver is not clearing the fault code so the sysfs link_state entry reports old/stale data. Revise the logic so that on successful link up the fault code is cleared. Signed-off-by:

The existing MDS loopback diagnostics support processing received frames in the slowpath work thread. It caps the number of frames it will process at 64, before waiting for another event to indicate additional frame reception. The net-net is this results in very slow frame processing during loopback tests and sometimes orphans an io, causing the loopback test to report failure by the switch. Move MDS loopback frame processing out of the slow path worker thread and into the normal RQ processing routines. Signed-off-by:

If the adapter is taken offline, the trunk link port attributes continue to report trunk links as up even though all links are down as the adapter is offline. Clear the trunk links state as part of taking the adapter offline. Signed-off-by:

Although MegaRAID controllers support 64-bit DMA addressing, as per hardware design, DMA address with all 64-bits set (0xFFFFFFFF-FFFFFFFF) results in a firmware fault. Driver will set 63-bit DMA mask to ensure the above address will not be used. Cc: stable@vger.kernel.org Signed-off-by:

Due to hardware errata in Aero controllers, reads to certain fusion registers could intermittently return zero. This behavior is transient in nature and subsequent reads will return valid value. For Aero controllers, any calls to readl to read from certain registers will be retried for maximum three times, if read returns zero. Signed-off-by:

With commit 09c2f95a ("scsi: mpt3sas: Swap I/O memory read value back to cpu endianness"), 64bit writes in _base_writeq() were rewritten to use __raw_writeq() instad of writeq(). This introduced a bug apparent on powerpc64 systems such as the Raptor Talos II that causes the HBA to drop from the PCIe bus under heavy load and being reinitialized after a couple of seconds. It can easily be triggered on affacted systems by using something like fio --name=random-write --iodepth=4 --rw=randwrite --bs=4k --direct=0 \ --size=128M --numjobs=64 --end_fsync=1 fio --name=random-write --iodepth=4 --rw=randwrite --bs=64k --direct=0 \ --size=128M --numjobs=64 --end_fsync=1 a couple of times. In my case I tested it on both a ZFS raidz2 and a btrfs raid6 using LSI 9300-8i and 9400-8i controllers. The fix consists in resembling the write ordering of writeq() by adding a mandatory write memory barrier before device access and a compiler barrier afterwards. The additional MMIO barrier is superfluous. Signed-off-by:

The intent of invoking configfs_depend_item in commit 7474f52a ("tcm_qla2xxx: Perform configfs depend/undepend for base_tpg") was to prevent a physical Fibre Channel port removal when virtual (NPIV) ports announced through that physical port are active. The change does not work as expected: it makes enabled physical port dependent on target configfs subsystem (the port's parent), something the configfs guarantees anyway. Besides, scheduling work in a worker thread and waiting for the work's completion is not really a valid workaround for the requirement not to call configfs_depend_item from a configfs callback: the call occasionally deadlocks. Thus, removing configfs_depend_item calls does not break anything and fixes the deadlock problem. Signed-off-by:

In this case, do not set queue->page_count to 0 in lpfc_sli4_queue_alloc() as this will prevent the driver from initializing.

The same effects can be achieved by setting the dma_boundary to PAGE_SIZE - 1 and the max_segment_size to PAGE_SIZE, so shift those settings into the drivers. Note that in many cases the setting might be bogus, but this keeps the status quo. [mkp: fix myrs and myrb] Signed-off-by:
