Start to migrate to loop stoppable from cpu side, where we can immediately stop long running job via simple memory write instead of waiting until loop will complete all iterations. v2: - adjust test number of children according to available ram - add compute-preempt-many-all-ram subtest Cc: Francois Dugast Cc: Priyanka Dandamudi Zbigniew Kempczyński (5): lib/intel_compute: add support for stoppable loop lib/intel_compute_square_kernels: use stoppable loop for LNL/BMG lib/intel_compute_square_kernel: add loop shader binary for PTL tests/xe_compute_preempt: adjust number of children according to ram size tests/xe_compute_preempt: consume all ram for wmtp lib/intel_compute.c | 39 ++++++++++++--- lib/intel_compute.h | 2 + lib/intel_compute_square_kernels.c | 77 ++++++++++++++++++++++++++++++ opencl/loop.cl | 9 ++++ tests/intel/xe_compute_preempt.c | 54 ++++++++++++++++++--- 5 files changed, 168 insertions(+), 13 deletions(-) create mode 100644 opencl/loop.cl -- 2.34.1
