[igt-dev] [PATCH i-g-t v7 0/8] Make gpgpu fill tests libdrm independent

[Zbigniew Kempczyński]

I've introduced intel_bb which is very simplified version of libdrm
powered intel_batchbuffer. Currently it supports simple relocation
but it is enough to cover all gpgpu fill needs. Other (fenced) 
relocation will be added when I will have to face with such pipelines /
batchbuffers.

As commands created in gpu_cmds.c are coupled more than I thought on 
the beginning (media fill also use them) "_v2" suffix was introduced.
When all tests will be rewritten to "_v2" old functions can be removed
and "_v2" can be deleted.

v2: changes according to the review:
    - make intel_bb api more consistent and universal
    - add intel_bb api documentation
    - add alignment field in buf_ops buffer initalization for linear
      buffers
v3: changes:
    - add all gens pipelines
    - fix compiling issues on non-x86 archs
    - add ctx (suggested by knr)

v4: changes:
    - add indexing tree and render target write flag

v5: changes:
    - randomizing addresses to avoid relocations
    - fixing bug in gen8+ pipeline setup (Chris)

v6: changes:
    - fixing invalid realloc size
    - change invalid WB mapping to WC

v7: changes:
    - IS_BROADWELL() to IS_GEN8(), this is likely historical issue
      so lets CI verify

Zbigniew Kempczyński (8):
  lib/intel_bufops: Add bufops reference and adapt stride requirement
  lib/rendercopy_bufmgr: Pass alignment during buffer initialization
  lib/intel_batchbuffer: Introduce intel_bb
  lib/gpu_cmds: Add gpgpu pipeline functions based on intel_bb
  lib/gpgpu_fill: libdrm-free gpgpu pipeline creation
  lib/intel_batchbuffer: Introduce temporary igt_fillfunc_v2_t
  tests/gem_gpgpu_fill: Remove libdrm dependency
  HAX: run gpgpu_fill in BAT only
