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

2023-06-15T01:13:40+00:00

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"

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.

scsi: aacraid: Drop redundant pci_enable_pcie_error_reporting()

2023-03-10T03:00:38+00:00

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().

scsi: aacraid: Allocate cmd_priv with scsicmd

2023-02-08T23:49:48+00:00

The aac_priv() helper assumes that the private cmd area immediately follows struct scsi_cmnd. Allocate this space as part of scsicmd, else there is a risk of heap overflow.
