scsi: pmcraid: Don't use GFP_DMA in pmcraid_alloc_sglist()

2021-12-23T04:44:12+00:00

The driver doesn't express DMA addressing limitation under 32-bits anywhere
else, so remove the spurious GFP_DMA allocation.

scsi: core: Remove the 'done' argument from SCSI queuecommand_lck functions

2021-10-17T01:32:16+00:00

The DEF_SCSI_QCMD() macro passes the addresses of the SCSI host lock and
also that of the scsi_done function to the queuecommand_lck() function
implementations. Remove the 'scsi_done' argument since its address is
now a constant and instead call 'scsi_done' directly from inside the
queuecommand_lck() functions.

scsi: pmcraid: Call scsi_done() directly

2021-10-17T01:31:40+00:00

Conditional statements are faster than indirect calls. Hence call
scsi_done() directly.

scsi: pmcraid: Use generic power management

2020-11-26T04:23:22+00:00

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.

scsi: pmcraid: Drop PCI Wakeup calls from .resume

2020-11-26T04:23:22+00:00

The driver calls pci_enable_wake(...., false) in pmcraid_resume(), and
there is no corresponding pci_enable_wake(...., true) in pmcraid_suspend().
Either it should do enable-wake the device in .suspend() or should not
invoke pci_enable_wake() at all.

Concluding that this driver doesn't support enable-wake and PCI core calls
pci_enable_wake(pci_dev, PCI_D0, false) during resume, drop it from
pmcraid_resume().
