From: Lionel Landwerlin Date: Sun, 26 Aug 2018 13:35:30 +0000 (+0100) Subject: intel/aub_write: switch to use i915_drm engine classes X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6ef46972d953a3821ea083f36f930407f0663af8;p=mesa.git intel/aub_write: switch to use i915_drm engine classes Prepare aub write to deal with multiple engine instances. We don't pass the instance number yet this could be done in the future by having a 2 dimensional array of struct engine.
