Re: [PATCH 2/7] drm/i915/guc: Kill USES_GUC_SUBMISSION macro

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



-    if (USES_GUC_SUBMISSION(dev_priv)) {
+    if (intel_uc_uses_guc_submission(&dev_priv->gt.uc)) {
 nit: that old macro was helpful exactly in cases where only dev_priv
is known and component might have no idea where to find uc
 maybe we should have helper like:
      #define to_intel_uc(i915) (&(i915)->gt.uc)
 (but likely Jani will complain)


IMO the problem here is that we shouldn't really be going down to the uc from the dev_priv level, as intel_uc is now a subfeature of the GT. We've already removed a lot of the existing checks at the dev_priv level and this series gets rid of a few more; I guess once they're reduced enough in number we can consider replacing them with a check at the GT level.

so maybe we should introduce right now:

static inline bool intel_gt_uses_guc_submission(struct intel_gt *gt)
{
	return intel_uc_uses_guc_submission(&gt->uc);
}

and use it where we operate at gt level
