Author: José Roberto de Souza <jose.so...@intel.com> Date: Sun Dec 3 15:15:54 2023 -0800 intel/isl: Set mocs.blitter_dst/src for MTL This fields are required to be set because those are used by XY_FAST_COLOR_BLT instruction. Right now it is not set causing applications to abort because DestinationMOCS is required to be non-zero. This fixes at least piglit@ext_external_objects-vk-image-display on MTL.
