[igt-dev] [PATCH i-g-t v3 4/4] lib/intel_batchbuffer: Move batch functions from media/render/gpgpu libs

Lukasz Kalamarz lukasz.kalamarz at intel.com
Tue Apr 17 09:11:00 UTC 2018


Batch functions were copy/pasted across several libs.
With moving it into intel_batchbuffer lib test can now be
easly maintained without worrying that we forgot to modify
older version of lib.

v2: Added documentation into lib and rebased patch
v3: Fixed typos and rebased patch
