Hi, > Per context, then you can remove the locking. It's fitting since the scratch page is per-context anyway. The scratch page is per context? This I did not know, I thought it was per PPGTT. If that is the case, then my proposed interface to get/set the scratch page contents is wrong because it does not pass the HW context id. -Kevin _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
