[igt-dev] [PATCH 1/2] lib: Copy intel_gpu_commands.h from the kernel
Vikas Srivastava

Tue Mar 7 16:17:12 UTC 2023
From: Chris Wilson <chris.p.wilson at linux.intel.com>
Cherry picking this patch to fix conflicts while merging
patch to resolve gem_exec_await timeout issue.
The current version of intel_gpu_commands lacks a few definitions and
has a couple of mistakes. This patch should be pushed to the kernel,
along with any other cleanups, and then copied back here.
