This necessitates submitting a fastcolor blit as WABB and setting the copy engine arbitration to round-robin mode. v2: - Rename old platform check in second patch to match declaration in first patch. - Refactor second patch name to match first patch. v3: - Move NEEDS_FASTCOLOR_BLT_WABB to intel_gt.h. - Refactor NEEDS_FASTCOLOR_BLT_WABB to make it more streamlined to use. - Stop dividing PAGE_SIZE by sizeof(u32) when computing ctx_bb_ggtt_addr for lrc_setup_bb_per_ctx. - Reduce comment complexity. - Fix several checkpatch warnings. v4: - Actually stop dividing PAGE_SIZE by sizeof(u32) when computing ctx_bb_ggtt_addr for lrc_setup_bb_per_ctx. v5: - Stop dividing PAGE_SIZE by sizeof(u32) in check_ring_start during lrc live selftest. v6: - Append MI_BATCH_BUFFER_END to end of all PER_CTX_BB command streams. - No longer skip on empty, as command stream will never be empty (always contains at least MI_BATCH_BUFFER_END). - No longer append MI_NOOP until cachline aligned (was a fragment from INDIRECT_CTX setup). v7: - Use 0x6b instead of 0 for color to maintain functionality.
