From: Chris Wilson Date: Wed, 5 Jul 2017 14:26:32 +0000 (+0100) Subject: drm/i915: Move stale context reaping to common i915_gem_context_create X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ddfc925851b4f0ae36b21a5b545e4002c4259c42;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Move stale context reaping to common i915_gem_context_create We need to reap the stale contexts for all new contexts, be they created by user in i915_gem_context_ioctl or from opening a new file in i915_gem_context_open. Both paths may be called very frequently accumulating many stale contexts before any worker has a chance to run and free their memory.
