[igt-dev] [PATCH i-g-t 1/1] i915/gem_blits: Add check for hardware based FENCE support

[Ayaz A Siddiqui <ayaz.siddiqui@intel.com>]

This test is verifying various tiled source and destination data
combination for blitter using FENCE based tiling. Since blitter don't use
FENCE after Gen4+ so this test can only be useful for Platform prior to Gen4.

A check has been added to skip this test if fences are not available in
platform.
