[igt-dev] [PATCH i-g-t v7 0/9] Introduce blt_cmd_info struct

[Karolina Stolarek]

This patch series introduces a new way of checking if a specific
tiling format and/or blitter copy command is supported on
the current platform. Instead of using functions with hardcoded
devices, now we store information about available features in
blt_cmd_info struct, each of the instances connected to the
intel_device_info definitions.

Two patches that follow the introduction of blt_cmd_info and 
intel_device_info modification are a prep work for the fast
copy test -- extracting needed functions and updating
fill_data() to support TileYF (available only for Pre-gen12).

In addition to this, the patchset adds two fast copy tests: basic
fast-copy where two blit copies are done in separate batches, and
fast-copy-emit which uses emit_blt_fast_copy() and manually
crafts two copies in one batch.

v7:
  - Break down the first patch in the series into three separate
    changes (Zbigniew)
  - Add requirement for "gem_uses_full_ppgtt(i915)" to
    gem_exercise_blt (Zbigniew)
  - Rename supported_tiling field in blt_cmd_info to supported_cmds
    (Zbigniew)
  - Add GET_BLT_INFO in i915_blt.c to wrap calls to
    intel_get_blt_info

v6:
  - Rename the library to intel_tiling_info, and keep only struct
    definitions there
  - Move predicates to i915_blt.c, as this is going to be the main
    user of the library
  - Regenerate patch "lib/i915_blt: Add common functions for
    blt_copy_object", as i915_blt.(ch) significantly changed after
    rewriting the first patch

v5:
  - Rebase, fix conflict in gem_ccs.c

v4:
  - Move the inclusion of igt_core.h to intel_blt_info.c
    (Kamil/Petri)
  - Rename __MAX_TILING and __MAX_CMD so they are blitter-specific 
    (Kamil)
  - Use BIT() macro from intel_chipset.h (Zbigniew)
  - Check for empty blt_tiling_info in tiling_info(), and warn
    about it
  - Change blt_cmd_info declarations in intel_blt_info. Add a
    separate file for their definitions (intel_tiling_info.c).
    Update lib/mason.build to reflect that change (Zbigniew)
  - Remove definitions for ATS-M, as we can reuse dg2's (Zbigniew)
  - Add EXEC_OBJECT_WRITE flag for dest in fast-copy-emit subtest
    (Zbigniew)
