[igt-dev] [PATCH i-g-t 0/3] Try to have one less blitter path.

[Juha-Pekka Heikkila]

Here switch blitcopy in igt_fb.c to use lib/i915/i915_blt functions. This allow
start to use blitter path for doing rc ccs comression with new hardware, here
limit is set at having flat ccs since i915_blt functions didn't have aux ccs
support.

For compressing mc ccs still need to use Vebox copy as it seems copy engine
doesn't support destination compression with mc ccs.

  lib/i915/i915_blt: Add offset to block and fast copy
  lib/igt_fb: switch blitcopy to use lib/i915/i915_blt functions
  lib/igt_fb: use blitter for rendercompression on Intel hw with flat
    ccs
