Subject: drm/amdgpu: add gfx11 emit shadow callback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Add ring callback for gfx to update the CP firmware
with the new shadow information before we process the
IB.
v2: add implementation for new packet (Alex)
v3: add current FW version checks (Alex)
v4: only initialize shadow on first use
Only set IB_VMID when a valid shadow buffer is present
(Alex)
v5: Pass parameters rather than job to new ring callback (Alex)
