[PATCH 0/1] scsi: ufs: Add support for Auto-Hibernate Idle Timer

Hi Micha?? Potomski has previously sent a patch for this, but this patch is slightly different, based on the latest ufs-sysfs changes, it also takes care to restore auto-hibernate during resume, and otherwise avoids updating the register if the device is runtime suspended. Also a default value of

[PATCH 1/1] scsi: ufs: Add support for Auto-Hibernate Idle Timer

UFS host controllers may support an autonomous power management feature called the Auto-Hibernate Idle Timer. The timer is set to the number of microseconds of idle time before the UFS host controller will autonomously put the link into Hibernate state. That will save power at the expense of increa

[PATCH v4 01/13] lpfc: Rework lpfc to allow different sli4 cq and eq handlers

Up until now, an SLI-4 device had no variance in the way it handled its EQs and CQs. With newer hardware, there are now differences in doorbells and some differences in how entries are valid. Prepare the code for new hardware by creating a sli4-based callout table that can be set based on if_type.

[PATCH v4 02/13] lpfc: Rework sli4 doorbell infrastructure

Up until now, all SLI-4 devices had the same doorbells at the same bar locations. With newer hardware, there are now independent EQ and CQ doorbells and the bar locations differ. Prepare the code for new hardware by separating the eq/cq doorbell into separate components. The components can be set

[PATCH v4 03/13] lpfc: Add SLI-4 if_type=6 support to the code base

New hardware supports a SLI-4 interface, but with a new if_type variant of 6. If_type=6 has a different PCI BAR map, separate EQ/CQ doorbells, and some changes in doorbell formats. Add the changes for the if_type into headers, adapter initialization and control flows. Add new eq and cq handlers.

[PATCH v4 04/13] lpfc: Add push-to-adapter support to sli4

New if_type=6 adapters support an additional BAR that provides apertures to allow direct WQE to adapter push support - termed Direct Packet Push (DPP). WQ creation differs slightly to ask for a WQ to be DPP-ized. When submitting a WQE to a DPP WQ, it is submitted to the host memory for the WQ norma

[PATCH v4 08/13] lpfc: Enable fw download on if_type=6 devices

Current code is very explicit in what it allows to be downloaded. The driver checking prevented G7 firmware download. The driver checking is unnecessary as the device will validate what it receives. Revise the firmware download interface checking. Added a little debug support in case there is stil

[PATCH v4 07/13] lpfc: Add if_type=6 support for cycling valid bits

Traditional SLI4 required the driver to clear Valid bits on EQEs and CQEs after consuming them. The new if_type=6 hardware will cycle the value for what is valid on each queue itteration. The driver no longer has to touch the valid bits. This also means all the cpu cache dirtying and perhaps flush

[PATCH 2/2] scsi: mpt3sas: wait for and flush running commands on shutdown/unload

From: Sreekanth Reddy This patch finishes all outstanding SCSI IO commands (but not other commands, e.g., task management) in the shutdown and unload paths. It first waits for the commands to complete (this is done after setting 'ioc->remove_host = 1 ', which prevents new commands to be queued)

This patch adds checks for 'ioc->remove_host' in the SCSI error handlers, so not to access pointers/resources potentially freed in the PCI shutdown/module unload path. The error handlers may be invoked after shutdown/unload, depending on other components. This problem was observed with kexec on a

[PATCH v3 0/2] scsi: mpt3sas: prevent oops in the shutdown/unload path

The first patch prevents the SCSI error handlers to run once the shutdown/unload path starts. This avoids an oops at least in the host reset handler, on kernels with a recent patch, and also in the abort handler on kernels without that patch. The second patch goes a step further, and prevents th
