[igt-dev] [PATCH i-g-t v27 20/36] tests/api_intel_bb: Modify test to verify intel_bb with allocator
Zbigniew Kempczyński
zbigniew.kempczynski at intel.com
Thu Mar 18 11:23:51 UTC 2021
intel_bb was adopted to use allocator. Change the test to verify
addresses in different scenarios - with relocations and with softpin.
v2: adding intel-buf to intel-bb inserts addresses so they should
be same even if intel-bb cache purge was called
