Pull SCSI updates from James Bottomley: "Updates to the usual drivers (qla2xxx, lpfc, ufs, hisi_sas, mpi3mr, mpt3sas, target). The biggest change (from my biased viewpoint) being that the mpi3mr now attached to the SAS transport class, making it the first fusion type device to do so. Beyond the usual bug fixing and security class reworks, there aren't a huge number of core changes" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (141 commits) scsi: iscsi: iscsi_tcp: Fix null-ptr-deref while calling getpeername() scsi: mpi3mr: Remove unnecessary cast scsi: stex: Properly zero out the passthrough command structure scsi: mpi3mr: Update driver version to 8.2.0.3.0 scsi: mpi3mr: Fix scheduling while atomic type bug scsi: mpi3mr: Scan the devices during resume time scsi: mpi3mr: Free enclosure objects during driver unload scsi: mpi3mr: Handle 0xF003 Fault Code scsi: mpi3mr: Graceful handling of surprise removal of PCIe HBA scsi: mpi3mr: Schedule IRQ kthreads only on non-RT kernels scsi: mpi3mr: Support new power management framework scsi: mpi3mr: Update mpi3 header files scsi: mpt3sas: Revert "scsi: mpt3sas: Fix ioc->base_readl() use" scsi: mpt3sas: Revert "scsi: mpt3sas: Fix writel() use" scsi: wd33c93: Remove dead code related to the long-gone config WD33C93_PIO scsi: core: Add I/O timeout count for SCSI device scsi: qedf: Populate sysfs attributes for vport scsi: pm8001: Replace one-element array with flexible-array member scsi: 3w-xxxx: Replace one-element array with flexible-array member scsi: hptiop: Replace one-element array with flexible-array member in struct hpt_iop_request_ioctl_command() ...

scsi: ufs: wb: Add explicit flush sysfs attribute

2022-08-23T03:15:11Z

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.

scsi: ufs: core: Allow host driver to disable wb toggling during clock scaling

2022-08-23T03:07:50Z

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.

scsi: ufs: core: Use local_clock() for debugging timestamps

2022-08-23T03:03:30Z

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).
