[igt-dev] [PATCH i-g-t v4 0/3] xe: Validate fixed CCS mode setting

[Niranjana Vishwanathapura]

Validate static assignment of compute slices to a user selected
number of compute engines. Select number of compute engines by
writing it to the per-gt 'ccs_mode' sysfs interface. Validate
that compute kernels can be run on enabled CCS engines and
submitting jobs on disabled compute engines is not permitted.

NOTE: Corresponding driver changes is,
