[Intel-gfx] [PATCH i-g-t 02/12] lib/i915/intel_memory_region: Add memory regions stubs
Matthew Auld
matthew.auld at intel.com
Tue May 11 16:51:07 UTC 2021
From: Andrzej Turko <andrzej.turko at linux.intel.com>
Added stubs for memory regions to make upstreaming of tests which are
using this interface possible.
The memory region uapi implementation in the driver is not stable yet.
Thus, the full memory region interface cannot be used in lib. This
commit adds stubs for this uapi to be used in tests. This way future
introduction of the full memory regions uapi will trigger
much smaller changes in tests.
