Merge patch series "Eight small UFS patches"

2025-10-24T02:20:44Z

Bart Van Assche says: Hi Martin, This patch series includes two bug fixes for this development cycle and six small patches that are intended for the next merge window. If applying the first two patches only during the current development cycle would be inconvenient, postponing all patches until the next merge window is fine with me. Please consider including these patches in the upstream kernel. Thanks, Bart.

scsi: ufs: core: Update CQ Entry to UFS 4.1 format

2025-10-22T01:16:04Z

Update the completion queue (CQ) entry format according to the UFS 4.1 specification. UFS 4.1 introduces new members in reserved record DW5. Also refine DW4 with detailed members defined in UFS 4.0. Modify the code to incorporate these changes by updating the overall_status in the CQ entry structure.

scsi: ufs: core: Include UTP error in INT_FATAL_ERRORS

2025-09-30T20:10:29Z

When a UTP error occurs in isolation, UFS is not currently recoverable. This is because the UTP error is not considered fatal in the error handling code, leading to either an I/O timeout or an OCS error. Add the UTP error flag to INT_FATAL_ERRORS so the controller will be reset in this situation. sd 0:0:0:0: [sda] tag#38 UNKNOWN(0x2003) Result: hostbyte=0x07 driverbyte=DRIVER_OK cmd_age=0s sd 0:0:0:0: [sda] tag#38 CDB: opcode=0x28 28 00 00 51 24 e2 00 00 08 00 I/O error, dev sda, sector 42542864 op 0x0:(READ) flags 0x80700 phys_seg 8 prio class 2 OCS error from controller = 9 for tag 39 pa_err[1] = 0x80000010 at 2667224756 us pa_err: total cnt=2 dl_err[0] = 0x80000002 at 2667148060 us dl_err[1] = 0x80002000 at 2667282844 us No record of nl_err No record of tl_err No record of dme_err No record of auto_hibern8_err fatal_err[0] = 0x804 at 2667282836 us --------------------------------------------------- REGISTER --------------------------------------------------- NAME OFFSET VALUE STD HCI SFR 0xfffffff0 0x0 AHIT 0x18 0x814 INTERRUPT STATUS 0x20 0x1000 INTERRUPT ENABLE 0x24 0x70ef5 [mkp: commit desc] Signed-off-by: Hoyoung Seo Reviewed-by: Bart Van Assche Message-Id: <20250930061428.617955-1-hy50.seo@samsung.com> Signed-off-by: Martin K.

scsi: Revert "scsi: ufs: core: Probe for EXT_IID support"

2025-01-10T21:38:21Z

This reverts commit 6e1d850acff9477ae4c18a73c19ef52841ac2010. Although added a while ago, to date no one make use of ext_iid, specifically incorporates it in the upiu header. Therefore, remove it as it is currently unused and not serving any purpose.

scsi: ufs: Prepare to add HCI capabilities sysfs

2024-08-13T02:11:23Z

Prepare so we'll be able to read various other HCI registers. While at it, fix the HCPID & HCMID register names to stand for what they really are. Also replace the pm_runtime_{get/put}_sync() calls in auto_hibern8_show to ufshcd_rpm_{get/put}_sync() as any host controller register reads should.

scsi: ufs: core: Check LSDBS cap when !mcq

2024-07-16T02:51:06Z

If the user sets use_mcq_mode to 0, the host will try to activate the LSDB mode unconditionally even when the LSDBS of device HCI cap is 1. This makes commands time out and causes device probing to fail. To prevent that problem, check the LSDBS cap when MCQ is not supported.
