[Intel-gfx] [PATCH v9 0/3] Apply Wa_16018031267 / Wa_16018063123

[Jonathan Cavitt]

Apply Wa_16018031267 / Wa_16018063123.  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.

v8:
- Revert v7.
- Add some reserved kernel space per vm to run the
  workaround on.

v9:
- Hide reserved kernel space per vm from userspace.

[Intel-gfx] [PATCH v9 2/3] drm/i915: Add WABB blit for Wa_16018031267 / Wa_16018063123

[Jonathan Cavitt]

Apply WABB blit for Wa_16018031267 / Wa_16018063123.
Additionally, update the lrc selftest to exercise the new
WABB changes.
