i915_gem_shrink_all — Shrink buffer object caches completely
unsigned long i915_gem_shrink_all ( | struct drm_i915_private * dev_priv); |
This is a simple wraper around i915_gem_shrink to aggressively shrink all
caches completely. It also first waits for and retires all outstanding
requests to also be able to release backing storage for active objects.
This should only be used in code to intentionally quiescent the gpu or as a last-ditch effort when memory seems to have run out.
