[PATCH 4/4] accel/ivpu: Use GEM shmem helper for all buffers
Stanislaw Gruszka
stanislaw.gruszka at linux.intel.com
Tue Oct 31 07:31:56 UTC 2023
From: Jacek Lawrynowicz <jacek.lawrynowicz at linux.intel.com>
Use struct drm_gem_shmem_object as a base for struct ivpu_bo.
This cuts by 50% the buffer management code.
