[Intel-gfx] [PATCH v2 0/4] mmio save restore refine in vgpu switch

[Weinan Li]

Merge switch_mmio_to_vgpu and switch_mmio_to_host, use delta update for
mocs save restore, deal host mocs value as fixed, it won't be changed after
initialization. These can save vgpu switch time to reduce CPU utilization
and improve GPU performance in GVT-g with multi-VMs.

v2: code rebase

Weinan Li (4):
  drm/i915/gvt: refine trace_render_mmio
  drm/i915/gvt: optimize for vGPU mmio switch
  drm/i915/gvt: refine mocs save restore policy
  drm/i915/gvt: load host render mocs once in mocs switch
