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.

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: Add gfp_t flags parameter to event notificationsAhmed S. Darwish1-2/+2
All call-sites of below libsas APIs: - sas_alloc_event() - sas_notify_port_event() - sas_notify_phy_event() have been converted to use the _gfp()-suffixed version. Modify the original APIs above to take a gfp_t flags parameter by default. For bisectability, call-sites will be modified again to use the original libsas APIs (while passing gfp_t). The temporary _gfp()-suffixed versions can then be removed.

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.

The gdth driver refers to a SCSI parallel, PCI-only HBA RAID adapter which was manufactured by the now-defunct ICP Vortex company, later acquired by Adaptec and superseded by the aacraid series of controllers. The driver itself would require a major overhaul before any modifications can be attempted, but seeing that it's unlikely to have any users left it should rather be removed completely.
