drm/i915/execlists: Use vfunc to check engine submission mode
While processing CSB there is no need to look at GuC submission settings, just check if engine is configured for execlists mode. While today GuC submission is disabled it's settings are still based on modparam values that might not correctly reflect actual submission status in case of any fallback. Until that is fully fixed, use alternate method to confirm that engine really runs in execlists mode by comparing set_default_submission vfunc. v2: add other immediate use of new helper Signed-off-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Janusz Krzysztofik <janusz.krzysztofik@linux.intel.com> Reviewed-by: Janusz Krzysztofik <janusz.krzysztofik@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20191028164520.31772-1-michal.wajdeczko@intel.com
