ata: Use named initializers for pci_device_id arrays

2026-06-12T09:44:30+00:00

While being less compact, using named initializers allows to more easily see which members of the structs are assigned which value without having to lookup the declaration of the struct. And it's also more robust against changes to the struct definition. The mentioned robustness is relevant for a planned change to struct pci_device_id that replaces .driver_data by an anonymous union. Also drop the comma after a few list terminators. This patch doesn't modify the compiled array, only their representation in source form benefits. The former was confirmed with x86 and arm64 builds.

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: libata-core: Rename ata_do_set_mode()

2025-07-04T08:36:00+00:00

With the renaming of libata-eh ata_set_mode() function to ata_eh_set_mode(), libata-core function ata_do_set_mode() can now be renamed to the simpler ata_set_mode(). All the call sites of the former ata_do_set_mode() are updated to use the new function name. No functional changes.

ata: make transfer mode masks unsigned int

2022-06-17T07:35:02+00:00

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
