ata: libata-eh: Simplify reset operation management

2025-07-16T07:31:43+00:00

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: pata_marvell: Check the 'bmdma_addr' beforing reading

2022-04-21T23:45:06+00:00

Before detecting the cable type on the dma bar, the driver should check whether the 'bmdma_addr' is zero, which means the adapter does not support DMA, otherwise we will get the following error: [ 5.146634] Bad IO access at port 0x1 (return inb(port)) [ 5.147206] WARNING: CPU: 2 PID: 303 at lib/iomap.c:44 ioread8+0x4a/0x60 [ 5.150856] RIP: 0010:ioread8+0x4a/0x60 [ 5.160238] Call Trace: [ 5.160470] [ 5.160674] marvell_cable_detect+0x6e/0xc0 [pata_marvell] [ 5.161728] ata_eh_recover+0x3520/0x6cc0 [ 5.168075] ata_do_eh+0x49/0x3c0 Signed-off-by: Zheyu Ma Signed-off-by: Damien Le Moal

ata: Use IS_ENABLED() instead of checking for built-in or module

2016-05-27T15:27:23+00:00

The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either built-in or as a module, use that macro instead of open coding the same. Signed-off-by: Javier Martinez Canillas Signed-off-by: Tejun Heo

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

2014-05-10T02:37:49+00:00

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

2014-02-13T21:40:56+00:00

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.
