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
("reports to engine instance 0") for MSI-X support.


Ilia Levi (5):
  drm/xe: move memirq out of vf
  drm/xe: memirq infra changes for msix
  drm/xe: add memirq offsets for engine instance 0 to hw engine
    properties
  drm/xe: memirq handler changes
  drm/xe: separate memirq reset/postinstall from vf
