[PATCH 6.6 002/122] ata: libata-core: Allow command duration limits detection for ACS-4 drives

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Igor Pylypiv <ipylypiv@xxxxxxxxxx>

commit c0297e7dd50795d559f3534887a6de1756b35d0f upstream.

Even though the command duration limits (CDL) feature was first added
in ACS-5 (major version 12), there are some ACS-4 (major version 11)
drives that implement CDL as well.

IDENTIFY_DEVICE, SUPPORTED_CAPABILITIES, and CURRENT_SETTINGS log pages
are mandatory in the ACS-4 standard so it should be safe to read these
log pages on older drives implementing the ACS-4 standard.

Fixes: 62e4a60e0cdb ("scsi: ata: libata: Detect support for command duration limits")
