commit 0a393229479d61829a2f8671c1a46f533c76b385 (HEAD, upstream/master) Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Mar 27 14:44:30 2018 +0100 igt/gem_ctx_isolation: Reset a scratch context If we inject a reset into the target context, there is a risk that the register state is never saved back to memory. The exact interaction between reset, the context image and the precise timing of our execution are not well defined. Since we cannot ensure that the context image remains valid, force a context switch prior to the reset.
