2022-12-30scsi: ufs: core: Allow UFS host drivers to override the sg entry sizeEric Biggers2-2/+37
Modify the UFSHCD core to allow 'struct ufshcd_sg_entry' to be variable-length. The default is the standard length, but variants can override ufs_hba::sg_entry_size with a larger value if there are vendor-specific fields following the standard ones. This is needed to support inline encryption with ufs-exynos (FMP).

2022-12-30scsi: ufs: core: bsg: Add advanced RPMB support in ufs_bsgBean Huo3-1/+11
Add advanced RPMB support in ufs_bsg: 1. According to the UFS specification, only one RPMB operation can be performed at any time. We can ensure this by using reserved slot and its dev_cmd sync operation protection mechanism. 2. For Advanced RPMB, RPMB metadata is packaged in an EHS (Extra Header Segment) of a command UPIU, and the corresponding reply EHS (from the device) should also be returned to the user space. bsg_job->request and bsg_job->reply allow us to pass and return EHS from/back to userspace. Compared to normal/legacy RPMB, the advantages of advanced RPMB are: 1. The data length in the Advanced RPMB data read/write command can be larger than 4KB. For the legacy RPMB, the data length in a single RPMB data transfer is 256 bytes. 2. All of the advanced RPMB operations will be a single command. For legacy RPMB, take the read write-counter value as an example, you need two commands (first SECURITY PROTOCOL OUT, then second SECURITY PROTOCOL IN).

2022-08-22scsi: ufs: wb: Add explicit flush sysfs attributeJinyoung Choi1-0/+1
There is the following quirk to bypass "WB Flush" in Write Booster. - UFSHCI_QUIRK_SKIP_MANUAL_WB_FLUSH_CTRL If this quirk is not set, there is no knob that can control "WB Flush". There are three flags that control Write Booster Feature: 1. WB ON/OFF 2. WB Hibern Flush ON/OFF (implicitly) 3. WB Flush ON/OFF (explicit) The sysfs attribute that controls the WB was implemented. (1) In the case of "Hibern Flush", it is always good to turn on. Control may not be required. (2) Finally, "Flush" may be necessary because the Auto-Hibern8 is not supported in a specific environment. So the sysfs attribute that controls this is necessary.

Mediatek UFS does not want to toggle write booster during clock scaling. Permit host driver to disable wb toggling during clock scaling. Introduce a flag UFSHCD_CAP_WB_WITH_CLK_SCALING to decouple WB and clock scaling. UFSHCD_CAP_WB_WITH_CLK_SCALING is only valid when UFSHCD_CAP_CLK_SCALING is set. Just like UFSHCD_CAP_HIBERN8_WITH_CLK_GATING is valid only when UFSHCD_CAP_CLK_GATING set. Set UFSHCD_CAP_WB_WITH_CLK_SCALING for qcom to compatible legacy design at the same time.

2022-08-22scsi: ufs: core: Use local_clock() for debugging timestampsDaniil Lunev1-5/+9
CLOCK_MONOTONIC is not advanced when the system is in suspend. This becomes problematic when debugging issues related to suspend-resume: the timestamps printed by ufshcd_print_trs can not be correlated with dmesg entries, which are timestamped with local_clock(). Change the used clock to local_clock() for the informational timestamp variables and adds mirroring *_local_clock instances for variables used in subsequent derevations (to not change the semantics of those derevations).
