Author: Chris Wilson <ch...@chris-wilson.co.uk> Date: Tue Apr 11 16:17:36 2017 +0100 i965: Report supported context priorities to EGL/DRI Hook up the RendererQuery for __DRI2_RENDERER_HAS_CONTEXT_PRIORITY to report the available DRM_I915_GEM_CONTEXT_SETPARAM options based on the per-client default context. The kernel will validate the request to change the property, so we get an accurate reflection of available support (based on kernel version and privilege) and we should only have to do it once during screen setup -- although the SETPARAM should be fast, they are still an ioctl each.
