Quoting Chris Wilson (2020-05-09 12:52:17) > i915_gem_evict_something() is charged with finding a slot within the GTT > that we may reuse. Since our goal is not to stall, we first look for a > slot that only overlaps idle vma. To this end, on the first pass we move > any active vma to the end of the search list. However, we only stopped > moving active vma after we see the first active vma twice. If during the > search, that first active vma completed, we would not notice and keep on > extending the search list. > > Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/1746 Fixes: 2850748ef876 ("drm/i915: Pull i915_vma_pin under the vm->mutex") Fixes: b1e3177bd1d8 ("drm/i915: Coordinate i915_active with its own mutex") > Signed-off-by: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> > Cc: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx> > Cc: <stable@xxxxxxxxxxxxxxx> # v5.5+ _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
