[PATCH i-g-t,v4 0/5] Stress copy engines during render

[Francois Dugast]

This series adds new tests to stress the copy engines with multiple jobs
in parallel, while measuring the impact on the execution duration of a
rendering job.

v3: Rename to xe_blt_mem_copy() and promote to xe_util instead of
    lib/intel_blt as this is xe-specific

v4: Follow Zbigniew's recommendation and adopt a new approach: the spinner
    is extended to optionnally perform copies. In the test, rndering only
    starts when copies are running. It runs for a defined time thanks to
    igt_until_timeout().

Francois Dugast (5):
  lib/intel_blt: Promote MEM_COPY_MOCS_SHIFT
  lib/xe/xe_spin: Add mem copy capability to spinner
  tests/intel/xe_spin_batch: Add basic test for mem copy from spinner
  tests/intel/xe_render_copy: Expose render duration
  tests/intel/xe_render_copy: Add new test for render under copy stress
