[PATCH 0/8] Add MSIX functionality to XE

[Dani Liberman]

This patch set enables MSIX workflow. The main changes are:

1. The code supports both msi and msix, some refactoring had
   to be done.
2. Since multiple interrupts are now available there is no need for
   interrupt aggregation in HW, hence there are new interrupt
   handlers.
3. MSIX interrupts are system resources so an interrupt allocator was
   implemented.
4. Adding MSIX infra to exec queues.
5. MSIX in GT also uses memirq, some refactoring had to be done to
   enable it.

Dani Liberman (3):
  drm/xe/irq: refactor irq flows to support also msix
  drm/xe/irq: add msix allocator
  drm/xe/exec: adding msix infra to exec queue

Ilia Levi (5):
  drm/xe/irq: add hw engine irq handler
  drm/xe: move the kernel lrc from hwe to execlist port
  drm/xe: move memirq out of vf
  drm/xe: msix support preparations - enable memirq
  drm/xe: msix support for hw engines
