[PATCH 0/2] Expose wmtp status as engine capability

[Nirmoy Das]

Xe2 supports mid thread preemption which is currently by default 
enabled. It is possible that the some HWs/platforms/engines disabled 
that feature. To expose that status, this series adds an engine capability 
which UMD can probe to determine if WMTP is supported for an engine.


Test-with: 20240809103922.12964-1-nirmoy.das at intel.com
Testcase: igt at xe_query@query-gt-list at query-engines-capabilities
UMD use-case:  https://github.com/intel/compute-runtime/pull/746
