From b5bb37eddb63b16b7ab959598d108b1c444be77d Mon Sep 17 00:00:00 2001 From: Bas Nieuwenhuizen Date: Wed, 30 Jan 2019 02:53:22 +0100 Subject: drm/amdgpu: Add command to override the context priority. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Given a master fd we can then override the priority of the context in another fd. Using these overrides was recommended by Christian instead of trying to submit from a master fd, and I am adding a way to override a single context instead of the entire process so we can only upgrade a single Vulkan queue and not effectively the entire process. Reused the flags field as it was checked to be 0 anyways, so nothing used it. This is source-incompatible (due to the name change), but ABI compatible.
