libata: Add ATA_HORKAGE_NO_NCQ_ON_ATI for Samsung 860 and 870 SSD.

2021-10-09T13:02:42+00:00

commit 7a8526a5cd51cf5f070310c6c37dd7293334ac49 upstream. Many users are reporting that the Samsung 860 and 870 SSD are having various issues when combined with AMD/ATI (vendor ID 0x1002) SATA controllers and only completely disabling NCQ helps to avoid these issues. Always disabling NCQ for Samsung 860/870 SSDs regardless of the host SATA adapter vendor will cause I/O performance degradation with well behaved adapters. To limit the performance impact to ATI adapters, introduce the ATA_HORKAGE_NO_NCQ_ON_ATI flag to force disable NCQ only for these adapters. Also, two libata.force parameters (noncqati and ncqati) are introduced to disable and enable the NCQ for the system which equipped with ATI SATA adapter and Samsung 860 and 870 SSDs. The user can determine NCQ function to be enabled or disabled according to the demand. After verifying the chipset from the user reports, the issue appears on AMD/ATI SB7x0/SB8x0/SB9x0 SATA Controllers and does not appear on recent AMD SATA adapters. The vendor ID of ATI should be 0x1002. Therefore, ATA_HORKAGE_NO_NCQ_ON_AMD was modified to ATA_HORKAGE_NO_NCQ_ON_ATI.

ata: sata_dwc_460ex: No need to call phy_exit() befre phy_init()

2021-09-18T11:43:44+00:00

[ Upstream commit 3ad4a31620355358316fa08fcfab37b9d6c33347 ] Last change to device managed APIs cleaned up error path to simple phy_exit() call, which in some cases has been executed with NULL parameter. This per se is not a problem, but rather logical misconception: no need to free resource when it's for sure has not been allocated yet. Fix the driver accordingly.

libata: add ATA_HORKAGE_NO_NCQ_TRIM for Samsung 860 and 870 SSDs

2021-09-18T11:43:24+00:00

commit 8a6430ab9c9c87cb64c512e505e8690bbaee190b upstream. Commit ca6bfcb2f6d9 ("libata: Enable queued TRIM for Samsung SSD 860") limited the existing ATA_HORKAGE_NO_NCQ_TRIM quirk from "Samsung SSD 8*", covering all Samsung 800 series SSDs, to only apply to "Samsung SSD 840*" and "Samsung SSD 850*" series based on information from Samsung. But there is a large number of users which is still reporting issues with the Samsung 860 and 870 SSDs combined with Intel, ASmedia or Marvell SATA controllers and all reporters also report these problems going away when disabling queued trims. Note that with AMD SATA controllers users are reporting even worse issues and only completely disabling NCQ helps there, this will be addressed in a separate patch.

The test on the host_stop field of host->ops must then be preceded by a check that host->ops is not NULL.

libata: fix ata_pio_sector for CONFIG_HIGHMEM

2021-07-09T14:28:20+00:00

Data transfers are not required to be block aligned in memory, so they span two pages. Fix this by splitting the call to >sff_data_xfer into two for that case. This has been broken since the initial libata import before the damn of git, but was uncovered by the legacy ide driver removal.
