The current only submission in the driver that doesn't use a vm is the WA setup. We still pass a vm structure (the migration one), but we don't actually use it at submission time and we instead have an hack to use GGTT for this particular engine. Instead of special-casing the WA engine, we can skip providing a VM and use that as selector for whether to use GGTT or PPGTT. As part of this change, we can drop the special engine flag for the WA engine and switch the WA submission to use the standard job functions instead of dedicated ones. v2: rebased on s/engine/exec_queue Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> Link: https://lore.kernel.org/r/20230822173334.1664332-4-daniele.ceraolospurio@intel.com Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
