2022-10-22scsi: core: Change the return type of .eh_timed_out()Bart Van Assche1-2/+5
Commit 6600593cbd93 ("block: rename BLK_EH_NOT_HANDLED to BLK_EH_DONE") made it impossible for .eh_timed_out() implementations to call scsi_done() without causing a crash. Restore support for SCSI timeout handlers to call scsi_done() as follows: * Change all .eh_timed_out() handlers as follows: - Change the return type into enum scsi_timeout_action. - Change BLK_EH_RESET_TIMER into SCSI_EH_RESET_TIMER. - Change BLK_EH_DONE into SCSI_EH_NOT_HANDLED. * In scsi_timeout(), convert the SCSI_EH_* values into BLK_EH_* values.

2022-07-18scsi: ufs: core: Read device property for ref clockDaniil Lunev1-0/+15
UFS storage devices require bRefClkFreq attribute to be set to operate correctly at high speed mode. The necessary value is determined by what the SoC / board supports. The standard doesn't specify a method to query the value, so the information needs to be fed in separately. DT information feeds into setting up the clock framework, so platforms using DT can get the UFS reference clock frequency from the clock framework. A special node "ref_clk" from the clock array for the UFS controller node is used as the source for the information. On the platforms that do not use DT (e.g. Intel), the alternative mechanism to feed the intended reference clock frequency is necessary. Specifying the necessary information in DSD of the UFS controller ACPI node is an alternative mechanism proposed in this patch. Those can be accessed via firmware property facility in the kernel and in many ways simillar to querying properties defined in DT. This patch introduces a small helper function to query a predetermined ACPI supplied property of the UFS controller, and uses it to attempt retrieving reference clock value, unless that was already done by the clock infrastructure.

2022-07-06scsi: core: Remove reserved request time-out handlingJohn Garry2-3/+2
The SCSI core code does not currently support reserved commands. As such, requests which time-out would never be reserved, and scsi_timeout() 'reserved' arg should never be set. Remove handling for reserved requests, drop the wrapper scsi_timeout() as it now just calls scsi_times_out() always, and finally rename scsi_times_out() -> scsi_timeout() to match the blk_mq_ops method name.

2021-01-22scsi: libsas: Introduce a _gfp() variant of event notifiersAhmed S. Darwish1-0/+2
sas_alloc_event() uses in_interrupt() to decide which allocation should be used. The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. The in_interrupt() check is also only partially correct, because it fails to choose the correct code path when just preemption or interrupts are disabled. For example, as in the following call chain: mvsas/mv_sas.c: mvs_work_queue() [process context] spin_lock_irqsave(mvs_info::lock, ) -> libsas/sas_event.c: sas_notify_phy_event() -> sas_alloc_event() -> in_interrupt() = false -> invalid GFP_KERNEL allocation -> libsas/sas_event.c: sas_notify_port_event() -> sas_alloc_event() -> in_interrupt() = false -> invalid GFP_KERNEL allocation Introduce sas_alloc_event_gfp(), sas_notify_port_event_gfp(), and sas_notify_phy_event_gfp(), which all behave like the non _gfp() variants but use a caller-passed GFP mask for allocations. For bisectability, all callers will be modified first to pass GFP context, then the non _gfp() libsas API variants will be modified to take a gfp_t by default.

2021-01-22scsi: libsas: Remove notifier indirectionJohn Garry1-6/+2
LLDDs report events to libsas with .notify_port_event and .notify_phy_event callbacks. These callbacks are fixed and so there is no reason why the functions cannot be called directly, so do that. This neatens the code slightly, makes it more obvious, and reduces function pointer usage, which is generally a good thing. Downside is that there are 2x more symbol exports.

Pull SCSI updates from James Bottomley: "This series has a huge amount of churn because it pulls in Mauro's doc update changing all our txt files to rst ones. Excluding that, we have the usual driver updates (qla2xxx, ufs, lpfc, zfcp, ibmvfc, pm80xx, aacraid), a treewide update for scnprintf and some other minor updates. The major core change is Hannes moving functions out of the aacraid driver and into the core" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (223 commits) scsi: aic7xxx: aic97xx: Remove FreeBSD-specific code scsi: ufs: Do not rely on prefetched data scsi: dc395x: remove dc395x_bios_param scsi: libiscsi: Fix error count for active session scsi: hpsa: correct race condition in offload enabled scsi: message: fusion: Replace zero-length array with flexible-array member scsi: qedi: Add PCI shutdown handler support scsi: qedi: Add MFW error recovery process scsi: ufs: Enable block layer runtime PM for well-known logical units scsi: ufs-qcom: Override devfreq parameters scsi: ufshcd: Let vendor override devfreq parameters scsi: ufshcd: Update the set frequency to devfreq scsi: ufs: Resume ufs host before accessing ufs device scsi: ufs-mediatek: customize the delay for enabling host scsi: ufs: make HCE polling more compact to improve initialization latency scsi: ufs: allow custom delay prior to host enabling scsi: ufs-mediatek: use common delay function scsi: ufs: introduce common and flexible delay function scsi: ufs: use an enum for host capabilities scsi: ufs: fix uninitialized tx_lanes in ufshcd_disable_tx_lcc() ...
2020-03-24scsi: simplify scsi_partsizeChristoph Hellwig1-21/+0
Call scsi_bios_ptable from scsi_partsize instead of requiring boilerplate code in the callers. Also switch the calling convention to match that of the ->bios_param instances calling this function, and use true/false for the return value instead of the weird -1 convention.

This file had its own peculiar style, not following any other files inside the Kernel (as far as I saw). Had to do a number of changes here, starting by removing the two leading asterisks from each line, adding table and literal block markups and changing whitespace and blank lines. The end result is that (IMHO), it is now a lot easier to read it as a text file, while producing a good html output.
