[igt-dev] [PATCH i-g-t v2 1/4] compute_square_kernel.cl: add CL file used at xe_compute.c

[Mauro Carvalho Chehab <mauro.chehab@linux.intel.com>]

From: Mauro Carvalho Chehab <mchehab@kernel.org>

Provide the cl file that it was used to produce the OpenCL
Kernel used by xe_compute, and document how the binary at
xe_compute.h was produced.
