[PATCH 00/10] Enable FW assisted shadowing for GFX11

This patch set allows for FW assisted shadowing on supported
platforms.  A new enough CP FW is required.  This feature is
required for mid command buffer preemption and proper SR-IOV
support.  This also simplifies the UMDs by allowing persistent
hardware state when the command submission executes.  UMDs
that use this will have their state retained across command

The mesa MR to implement the user mode side of this is:

Alex Deucher (8):
  drm/amdgpu: add UAPI to query GFX shadow sizes
  drm/amdgpu/UAPI: add new CS chunk for GFX shadow buffers
  drm/amdgpu/gfx11: make job optional in emit_gfx_shadow
  drm/amdgpu: don't require a job for cond_exec and shadow
  drm/amdgpu: add gfx shadow callback
  drm/amdgpu: add get_gfx_shadow_info callback for gfx11
  drm/amdgpu: add support for new GFX shadow size query
  drm/amdgpu: bump driver version number for CP GFX shadow

Christian König (2):
  drm/amdgpu: add gfx shadow CS IOCTL support
  drm/amdgpu: add gfx11 emit shadow callback
