[PATCH 0/3] Multi-CCS support in IGT

[nishit.sharma at intel.com]

From: Nishit Sharma <nishit.sharma at intel.com>

Revision 1:
Added loop_kernel_duration in available pipelines. loop_kernel_duration
holds sleep duration and during sleep GPU will be workng.
Patch-1/3: loop_kernel_duration addition in available pipelines in
lib/intel_compute.c. igt_skip is called in pipeline which doesn't support
loop_kernel shader.
Patch-2/3: Added loop-duration-2s subtest in tests/intel/xe_compute to
test if GPU is executing shader when sleep is called. This is verfied
using gputop in another terminal. This also tests whether the test
executed successfully in >= 2seconds of duration set
Patch-3/3: Added eu-busy-10s test which creates multi threads depending
on num_slices available and schedules workload on all ccs instances
available. This also prints engine utlization in percentage while
workload is executing.

v2:
- Addressed review comments from Zbyshek on description in Patch-1.
- Added execution time check in Patch-2 regarding single iteration of
  scheduling and executing workload on single instance of CCS engine.

v3:
- Added missing code section in Patch-1.
- Modified LOOP_DURATIOn macro to LOOP_DURATION_2s to avoid confusion.
- Used LOOP_DURATION_2s in place of LOOP_DURATION and adjusted sleep
  durations.
