[PATCH v5 0/5] memirq infra changes

[Ilia Levi]

From: Ilia Levi <ilia.levi at intel.com>


This patch set contains Memory Based Interrupts (memirq) infrastructure
changes to make it reusable for use cases other than VF 
(specifically MSI-X). 

The main changes are separation from VF and a new mode where hardware
engines report interrupt source and status to the offset of instance 0
(for MSI-X support).

v2: Rebase
v3: Rebase, refactor according to review comments (Michal)
v4: Rebase, address review comments (Michal)
v5: Rebase, fix more review comments (Michal)

  drm/xe: Introduce xe_device_uses_memirq()
  drm/xe: move memirq out of VF
