Browse source

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)
