scsi: aacraid: Reply queue mapping to CPUs based on IRQ affinity

2023-06-15T01:13:40Z

Fix the I/O hang that arises because of the MSIx vector not having a mapped online CPU upon receiving completion. SCSI cmds take the blk_mq route, which is setup during init. Reserved cmds fetch the vector_no from mq_map after init is complete. Before init, they have to use 0 - as per the norm.

Merge patch series "Constify most SCSI host templates"

2023-03-25T00:13:03Z

Bart Van Assche says: It helps humans and the compiler if it is made explicit that SCSI host templates are not modified. Hence this patch series that constifies most SCSI host templates. Please consider this patch series for the next merge window. Link: https://lore.kernel.org/r/20230322195515.1267197-1-bvanassche@acm.org Signed-off-by: Martin K. Petersen

scsi: aacraid: Drop redundant pci_enable_pcie_error_reporting()

2023-03-10T03:00:38Z

pci_enable_pcie_error_reporting() enables the device to send ERR_* Messages. Since commit f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is native"), the PCI core does this for all devices during enumeration, so the driver doesn't need to do it itself. Remove the redundant pci_enable_pcie_error_reporting() call from the driver. Note that this only controls ERR_* Messages from the device. An ERR_* Message may cause the Root Port to generate an interrupt, depending on the AER Root Error Command register managed by the AER service driver. Also remove pci_disable_pcie_error_reporting() from the .error_detected() path, which was added by commit 5c63f7f710bd ("aacraid: Added EEH support") but looks unnecessary. Error reporting will be disabled by the device reset and will be re-enabled by the pci_restore_state() in aac_pci_slot_reset().

blk-mq: Drop 'reserved' arg of busy_tag_iter_fn

2022-07-06T12:33:53Z

We no longer use the 'reserved' arg in busy_tag_iter_fn for any iter function so it may be dropped.

scsi: aacraid: Use generic power management

2020-11-26T04:14:30Z

Drivers should do only device-specific jobs. But in general, drivers using legacy PCI PM framework for .suspend()/.resume() have to manage many PCI PM-related tasks themselves which can be done by PCI Core itself. This brings extra load on the driver and it directly calls PCI helper functions to handle them. Switch to the new generic framework by updating function signatures and define a "struct dev_pm_ops" variable to bind PM callbacks. Also, remove unnecessary calls to the PCI Helper functions along with the legacy .suspend & .resume bindings.
