From: Chris Wilson Date: Wed, 17 May 2017 12:10:07 +0000 (+0100) Subject: drm/i915: Don't force serialisation on marking up execlists irq posted X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=955a4b8979fb558e8897f5b358ac77d2d423821d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Don't force serialisation on marking up execlists irq posted Since we coordinate with the execlists tasklet using a locked schedule operation that ensures that after we set the engine->irq_posted we always have an invocation of the tasklet, we do not need to use a locked operation to set the engine->irq_posted itself.
