[igt-dev] [PATCH] [PATCH i-g-t][V3]tests/i915/gem_sync.c :Added __for_each_physical_engine to utilize all available
Arjun Melkaveri
arjun.melkaveri at intel.com
Mon Apr 6 18:05:32 UTC 2020
Replaced the legacy for_each_engine* defines with the ones
implemented in the gem_engine_topology library.
Used gem_context_clone_with_engines
to make sure that engine index was potentially created
based on a default context with engine map configured.
Added gem_reopen_driver and gem_context_copy_engines
to transfer the engine map from parent fd default
context.
V2:
Added Legacy engine coverage for sync_ring and sync_all.
V3:
Added back ALL_ENGINES. Corrected Test cases that used
gem_reopen_driver in fork. Which was not recommended.
