[PATCH v9 00/10] Introduce Xe PCIe FLR

[PATCH v9 00/10] Introduce Xe PCIe FLR

[Raag Jadav]

Here's my humble attempt at introducing PCIe Function Level Reset (FLR)
support in xe driver. This is ofcourse a half baked implementation and
only limited to re-initializing GT. This needs to be extended for a lot
of components which are expected to be added as a follow up.

Detailed description in commit message and documentation.

PS: All xe_exec_basic tests and clpeak run smoothly after FLR. Give it
a spin and let me know if any regressions.

Trigger it with:

[PATCH v9 01/10] drm/xe/uc_fw: Allow re-initializing firmware

[Raag Jadav]

In preparation of usecases which require re-initializing firmware without
reloading the driver, introduce xe_uc_fw_reinit(). The uC firmware bo
already exists but since it's contents are on VRAM, they are lost on PCIe
FLR. Copy the firmware back to it's bo and mark it as loadable as part of
re-initialization.

[PATCH v9 02/10] drm/xe/guc_submit: Introduce guc_exec_queue_reinit_kernel()

[Raag Jadav]

In preparation of usecases which require re-initializing GuC submission
after PCIe FLR, introduce guc_exec_queue_reinit_kernel() helper. This will
restore kernel queues which might have been killed before PCIe FLR.

[PATCH v9 04/10] drm/xe/bo_evict: Introduce xe_bo_restore_map()

[Raag Jadav]

PCIe FLR clears all hardware state along with GGTT mappings of all
existing bos. Iterate over early and late kernel bo list and restore
their GGTT mappings in hardware, so that driver can make use of them
during re-initialization after PCIe FLR.

[PATCH v9 07/10] drm/xe/pm: Introduce xe_device_suspend/resume()

[Raag Jadav]

PCIe FLR prepare/re-initialization flows pretty much reflect system
suspend/resume flows with a few notable exceptions. Repurpose existing
helpers for PCIe FLR with an explicit flag to distinguish between both
flows.

[PATCH v9 08/10] drm/xe: Improve wedged state management

[Raag Jadav]

Currently, wedged state is serving a single usecase where the device is
permanently declared wedged, but this doesn't allow any wedged state
management for runtime usecases. In preparation of usecases which require
to facilitate temporary device wedging, convert wedged.flag to wedged.ref
which serves as a driver internal refcount for wedged state and blocks
critical path execution during device lifetime. While at it, introduce
wedged.perm which signifies permanent device wedging and operates
independent of the refcount allowing relevant cleanup action on unwind
path.

[PATCH v9 09/10] drm/xe/pci: Introduce PCIe FLR

[Raag Jadav]

With bare minimum pieces in place, we can finally introduce PCIe Function
Level Reset (FLR) support which re-initializes hardware state without the
need for reloading the driver from userspace. All VRAM contents are lost
along with hardware state and driver takes care of recreating the required
kernel bos as part of re-initialization, but user still needs to recreate
user bos and reload context after PCIe FLR.

+/**
+ * DOC: Xe PCI Error Handling
+ *
+ * Xe driver registers PCI callbacks which are called by PCI core in case of
+ * bus errors or resets.
+ *
+ * Currently only Function Level Reset (FLR) callbacks are supported. PCIe FLR
+ * wipes the VRAM and resets the state of all the hardware units. Therefore, the
+ * contents of all exec queues and BOs in VRAM are lost and the hardware needs a
+ * full re-initialization. The way Xe driver handles it, is pretty much similar
+ * to system suspend/resume flow with a few notable exceptions.
+ *
+ * Prepare phase:
+ *
+ * - Temporarily wedge the device to prevent userspace access
+ * - Kill exec queues which signals all fences and frees in-flight jobs
+ * - Stop the scheduler and all submissions to GuC
+ * - The fact that FLR is needed is because hardware could be in corrupted state
+ *   and access unreliable, so skip memory eviction due to untrustworthy VRAM
+ *   contents
+ * - Remove all memory mappings since VRAM contents will be lost
+ *
+ * Re-initialization phase:
+ *
+ * - Recreate kernel BOs due to skipped memory eviction in prepare phase
+ * - Restore kernel queues which were killed in prepare phase
+ * - Reload all uC firmwares
+ * - Bring up all hardware units
+ * - Unwedge the device to allow userspace access
+ *
+ * Since VRAM contents are lost, the user is expected to recreate user memory
+ * and reload context.
+ *
+ * TODO: Add PCIe error handling callbacks using similar flow.
+ *
+ * Current implementation is only limited to re-initializing GT. This needs to
+ * be extended for a lot of components listed below.
+ *
+ * - Proper re-initialization of GSC and PXP for integrated platforms
+ * - SR-IOV cases which need PF and VF synchronization
+ * - Re-initialization of all child devices registered by Xe
+ * - MM corner cases
+ * - Display

Sashiko pointed out what is likely a pre existing issue:


Can this mutex_lock() trigger a scheduling while atomic panic?
Looking at the call chain, xe_device_declare_wedged() can be invoked from
a hardirq context when a hardware error occurs:
xe_irq_handler()
  xe_mert_irq_handler()
    mert_handle_cat_error()
      xe_device_declare_wedged()
Since the interrupt handler runs in atomic context, acquiring a sleeping
lock here causes a crash.
Could this synchronization be handled without introducing a mutex in the
interrupt path?

This is an issue and currently unsafe too as we take mutexes deeper in
xe_device_declare_wedged call stack too. Maybe declare wedged in an
async work item? We have other issues in xe_device_declare_wedged too
which stop / start scheduling which also isn't safe unless this is on
the GT ordered work queue too.

Yes, the event call performs memory allocation for environment buffer
so mert was broken to begin with. But I'm not sure if that in scope of
series? Perhaps fix it separately? Michal?

Yes, I have planned this as part of my wedging improvement series once we
land this. It'll be reusing some parts of patch 3 where we use GT ordered
wq for it.
