On future hardware with missing GGTT BAR we won't be able to exercise
dma-buf access via that path. An alternative to basic-gtt subtest for
testing dma-buf access is required, as well as basic-fence-mmap and
coherency-gtt subtest alternatives for testing WC coherency.
Access to the dma sg list feature exposed by dma-buf can be tested
through blitter. Unfortunately we don't have any equivalently simple
tests that use blitter. Provide them.
Blitter XY_SRC_COPY method implemented by igt_blitter_src_copy__raw()
IGT library function has been chosen.
v2: As fast copy is not supported on platforms older than Gen 9,
use XY_SRC_COPY instead (Chris),
- bundle with a patch providing XY_SRC_COPY implementation,
- add subtest descriptions.
