From: Chris Wilson Date: Fri, 14 Aug 2015 11:59:19 +0000 (+0100) Subject: drm/i915: Flag the execlists context object as dirty after every use X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=903ecd0bb970438c3a60c2c33ec9032d6443bf67;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git drm/i915: Flag the execlists context object as dirty after every use Everytime we use the logical context with execlists it becomes dirty (as the hardware will write the new register values afterwards, as well as the GPU state that will be used). We need to then flag the context as dirty everytime since after a swap-out/swap-in cycle the dirty flag will be cleared, and a further swap-out cycle will then loose the most recent GPU state.
