ata: libata-scsi: refactor ata_scsi_translate()

2026-03-04T12:19:55+00:00

commit bb3a8154b1a1dc2c86d037482c0a2cf9186829ed upstream. Factor out of ata_scsi_translate() the code handling queued command deferral using the port qc_defer callback and issuing the queued command with ata_qc_issue() into the new function ata_scsi_qc_issue(), and simplify the goto used in ata_scsi_translate(). While at it, also add a lockdep annotation to check that the port lock is held when ata_scsi_translate() is called. No functional changes.

commit ff4a46c278ac6a4b3f39be1492a4568b6dcc6105 upstream. The FTIDE010 has been missing some timing settings since its inception, since the upstream OpenWrt patch was missing these. The community has since come up with the appropriate timings.

ata: libata: Print features also for ATAPI devices

[ Upstream commit c8c6fb886f57d5bf71fb6de6334a143608d35707 ] Commit d633b8a702ab ("libata: print feature list on device scan") added a print of the features supported by the device for ATA_DEV_ATA and ATA_DEV_ZAC devices, but not for ATA_DEV_ATAPI devices. Fix this by printing the features also for ATAPI devices.

ata: libata: Call ata_dev_config_lpm() for ATAPI devices

However, it only called this function for ATA_DEV_ATA and ATA_DEV_ZAC devices, not for ATA_DEV_ATAPI devices. Additionally, commit d99a9142e782 ("ata: libata-core: Move device LPM quirk settings to ata_dev_config_lpm()") moved the LPM quirk application from ata_dev_configure() to ata_dev_config_lpm(), causing LPM quirks for ATAPI devices to no longer be applied. Call ata_dev_config_lpm() also for ATAPI devices, such that LPM quirks are applied for ATAPI devices with an entry in __ata_dev_quirks once again.

ata: libata-core: Introduce ata_dev_config_lpm()

2026-02-06T15:44:04+00:00

[ Upstream commit d360121832d8a36871249271df5b9ff05f835f62 ] If the port of a device does not support Device Initiated Power Management (DIPM), that is, the port is flagged with ATA_FLAG_NO_DIPM, the DIPM feature of a device should not be used. Though DIPM is disabled by default on a device, the "Software Settings Preservation feature" may keep DIPM enabled or DIPM may have been enabled by the system firmware. Introduce the function ata_dev_config_lpm() to always disable DIPM on a device that supports this feature if the port of the device is flagged with ATA_FLAG_NO_DIPM. ata_dev_config_lpm() is called from ata_dev_configure(), ensuring that a device DIPM feature is disabled when it cannot be used.

ata: libata: cleanup fua support detection

2026-02-06T15:44:04+00:00

[ Upstream commit 4d2e4980a5289ae31a1cff40d258b68573182a37 ] Move the detection of a device FUA support from ata_scsiop_mode_sense()/ata_dev_supports_fua() to device scan time in ata_dev_configure(). The function ata_dev_config_fua() is introduced to detect if a device supports FUA and this support is indicated using the new device flag ATA_DFLAG_FUA. In order to blacklist known buggy devices, the horkage flag ATA_HORKAGE_NO_FUA is introduced. Similarly to other horkage flags, the libata.force= arguments "fua" and "nofua" are also introduced to allow a user to control this horkage flag through the "force" libata module parameter. The ATA_DFLAG_FUA device flag is set only and only if all the following conditions are met: * libata.fua module parameter is set to 1 * The device supports the WRITE DMA FUA EXT command, * The device is not marked with the ATA_HORKAGE_NO_FUA flag, either from the blacklist or set by the user with libata.force=nofua * The device supports NCQ (while this is not mandated by the standards, this restriction is introduced to avoid problems with older non-NCQ devices). Enabling or diabling libata FUA support for all devices can now also be done using the "force=[no]fua" module parameter when libata.fua is set to 1.

ata: libata-scsi: Fix system suspend for a security locked drive

2025-12-06T21:12:40+00:00

[ Upstream commit b11890683380a36b8488229f818d5e76e8204587 ] Commit cf3fc037623c ("ata: libata-scsi: Fix ata_to_sense_error() status handling") fixed ata_to_sense_error() to properly generate sense key ABORTED COMMAND (without any additional sense code), instead of the previous bogus sense key ILLEGAL REQUEST with the additional sense code UNALIGNED WRITE COMMAND, for a failed command. However, this broke suspend for Security locked drives (drives that have Security enabled, and have not been Security unlocked by boot firmware). The reason for this is that the SCSI disk driver, for the Synchronize Cache command only, treats any sense data with sense key ILLEGAL REQUEST as a successful command (regardless of ASC / ASCQ). After commit cf3fc037623c ("ata: libata-scsi: Fix ata_to_sense_error() status handling") the code that treats any sense data with sense key ILLEGAL REQUEST as a successful command is no longer applicable, so the command fails, which causes the system suspend to be aborted: sd 1:0:0:0: PM: dpm_run_callback(): scsi_bus_suspend returns -5 sd 1:0:0:0: PM: failed to suspend async: error -5 PM: Some devices failed to suspend, or early wake event detected To make suspend work once again, for a Security locked device only, return sense data LOGICAL UNIT ACCESS NOT AUTHORIZED, the actual sense data which a real SCSI device would have returned if locked. The SCSI disk driver treats this sense data as a successful command.
