[PATCH v1 0/6] Introduce Xe PCIe FLR

[Raag Jadav <raag.jadav@intel.com>]

Here's my humble attempt at introducing PCIe FLR support in xe driver.
This is ofcourse a half baked implementation and only limited to reloading
uC firmwares. This needs to be extended for a lot of different components
which I've skipped here for my lack of competence, so feel free to join
in and support them.

PS: This works enough to allow a single exec test run after FLR but it
follows with a GuC crash on subsequent runs which I'm still investigating.

Raag Jadav (6):
  drm/xe/uc_fw: Allow reloading firmware
  drm/xe/uc: Introduce FLR helpers
  drm/xe/irq: Introduce FLR helper
  drm/xe: Introduce xe_device_assert_lmem_ready()
  drm/xe/bo_evict: Introduce xe_bo_restore_map()
  drm/xe/pci: Introduce PCIe FLR
