ata: libata-scsi: scale DSM TRIM payload by MAX PAGES PER DSM COMMAND

2026-07-06T01:19:16+00:00

DSM TRIM currently always emits a single 512-byte page of LBA Range Entries (ATA_MAX_TRIM_RNUM == 64 ranges), regardless of how many pages the device can accept in one DATA SET MANAGEMENT command. The maximum is reported by MAX PAGES PER DSM COMMAND (IDENTIFY DEVICE word 105). Honour it: size the TRIM descriptor as a whole number of 512-byte pages, bounded by that limit and by the logical sector size (the WRITE SAME data-out buffer is a single logical block). Build and transfer only as many pages as the request needs, and set the DSM COUNT field, qc->nbytes and the maximum WRITE SAME length in the Block Limits VPD page accordingly. Build the descriptor straight into the WRITE SAME data-out buffer using an atomic sg_miter mapping, instead of staging it in the shared ata_scsi_rbuf and copying it out. This removes the global ata_scsi_rbuf_lock and a memcpy from the TRIM path. While commit 9379e6b8e0f9 ("libata: Safely overwrite attached page in WRITE SAME xlat") replaced direct access to the data-out buffer with an intermediate step that writes the entries in the ata_scsi_rbuf buffer, this solution writes to the data-out buffer using sg_miter, which maps each segment with kmap_atomic (SG_MITER_ATOMIC), so it's highmem- and multi-segment-safe, and it's usable from the non-sleeping command-submission path (unlike the page_address() access that ata_scsi_rbuf originally replaced). A 512-byte-sector device still uses a single page, so its behaviour is unchanged. Add ata_id_dsm_max_pages() to read IDENTIFY DEVICE word 105.

ata: libata: Change libata.force to use the generic ATA_QUIRK_MAX_SEC quirk

2025-12-15T07:32:05+00:00

Modify the existing libata.force parameters "max_sec_128" and "max_sec_1024" to use the generic ATA_QUIRK_MAX_SEC quirk rather than individual quirks. This also allows us to remove the individual quirks ATA_QUIRK_MAX_SEC_128 and ATA_QUIRK_MAX_SEC_1024. Signed-off-by: Niklas Cassel Reviewed-by: Martin K.

ata: libata: Add ATA_QUIRK_MAX_SEC and convert all device quirks

2025-12-15T07:32:05+00:00

Add a new quirk ATA_QUIRK_MAX_SEC, which has a separate table with device specific values. Convert all existing ATA_QUIRK_MAX_SEC_XXX device quirks in __ata_dev_quirks to the new format. Quirks ATA_QUIRK_MAX_SEC_128 and ATA_QUIRK_MAX_SEC_1024 cannot be removed yet, since they are also used by libata.force, which functionally, is a separate user of the quirks. The quirks will be removed once all users have been converted to use the new format. The quirk ATA_QUIRK_MAX_SEC_8191 can be removed since it has no equivalent libata.force parameter.
