ata: libata-eh: Simplify reset operation management

2025-07-16T07:31:43Z

Introduce struct ata_reset_operations to aggregate in a single structure the definitions of the 4 reset methods (prereset, softreset, hardreset and postreset) for a port. This new structure is used in struct ata_port to define the reset methods for a regular port (reset field) and for a port-multiplier port (pmp_reset field). A pointer to either of these fields replaces the 4 reset method arguments passed to ata_eh_recover() and ata_eh_reset(). The definition of the reset methods for all drivers is changed to use the reset and pmp_reset fields in struct ata_port_operations. A large number of files is modifed, but no functional changes are introduced. Suggested-by: Niklas Cassel Signed-off-by: Damien Le Moal Reviewed-by: Niklas Cassel Reviewed-by: Martin K.

ata: make transfer mode masks unsigned int

2022-06-17T07:35:02Z

The packed transfer mode masks and also the {pio|mwdma|udma}_mask fields of *struct*s ata_device and ata_port_info are declared as *unsigned long* (which is a 64-bit type on 64-bit architectures) but actually the packed masks occupy only 20 bits (7 PIO modes, 5 MWDMA modes, and 8 UDMA modes) and the PIO/MWDMA/UDMA masks easily fit into just 8 bits each, so we can safely use (always 32-bit) *unsigned int* variables instead. This saves 745 bytes of object code in libata-core.o alone, not to mention LLDDs... Signed-off-by: Sergey Shtylyov Signed-off-by: Damien Le Moal

pata_amd: fix checking of DMA state

2021-10-12T08:46:55Z

Checking if DMA is enabled should be done via the ata_dma_enabled helper function, since the init state 0xff indicates disabled. Change based on code review, not tested due to lack of hardware. Signed-off-by: Reimar Döffinger Signed-off-by: Damien Le Moal

cs5536: add support for IDE controller variant

2017-08-11T17:35:07Z

Several legacy devices such as Geode-based Cisco ASA appliances and DB800 development board do possess CS5536 IDE controller with different PCI id than existing one. Using pata_generic is not always feasible as at least DB800 requires MSR quirk from pata_cs5536 to be used with vendor firmware.

ata: use CONFIG_PM_SLEEP instead of CONFIG_PM where applicable in host drivers

2014-05-10T02:37:49Z

This patch fixes host drivers to use CONFIG_PM_SLEEP instead of CONFIG_PM where applicable. Benefits of this change: * unused code is not being compiled in for CONFIG_PM=y, CONFIG_PM_SLEEP=n and CONFIG_PM_RUNTIME=y configurations * easier transition to use struct dev_pm_ops and SIMPLE_DEV_PM_OPS() in the future * more consistent code (there are host drivers which are using the correct CONFIG_PM_SLEEP checks already) The patch leaves the core libata code and ->port_[suspend,resume] support in sata_[inic162x,nv,sil24].c alone for now.

ata: delete non-required instances of include

2014-02-13T21:40:56Z

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.
