* [igt-dev] [PATCH i-g-t] tests/gem_render_copy: Add software tiling / detiling support

  To: igt-dev

Older GENs have mmapable GGTT which does buffer tiling / detaling
automatically. Newer GENs have looses this possibility so software
tiling / detiling is required.

Heavy code refactoring was done to allow configure specific tile buffer
operations regarding to GENx generation.
