Now we process user lookups using the rbtree, and we only use obj->vma_list itself for maintaining state (e.g. ensuring that all vma are flushed or rebound). As such maintenance needs to go on beyond the user's awareness of the vma, defer removal of the vma from the obj->vma_list from i915_vma_close() to i915_vma_destroy() Fixes: 5888fc9eac3c ("drm/i915: Flush pending GTT writes before unbinding") Bugzilla: <a class="bz_bug_link bz_status_CLOSED bz_closed" title="CLOSED FIXED - [CI] igt@gem_userptr_blits@sync-unmap-after-close - dmesg-warn - Failed to release pages: bind_count=1, pages_pin_count=1, pin_global=0" href="show_bug.cgi?id=104155">https://bugs.freedesktop.org/show_bug.cgi?id=104155</a> Signed-off-by: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>> Cc: Joonas Lahtinen <<a href="mailto:joonas.lahtinen@linux.intel.com">joonas.lahtinen@linux.intel.com</a>> Cc: Tvrtko Ursulin <<a href="mailto:tvrtko.ursulin@intel.com">tvrtko.ursulin@intel.com</a>> Link: <a href="https://patchwork.freedesktop.org/patch/msgid/20171206124914.19960-1-chris@chris-wilson.co.uk">https://patchwork.freedesktop.org/patch/msgid/20171206124914.19960-1-chris@chris-wilson.co.uk</a> Reviewed-by: Joonas Lahtinen <<a href="mailto:joonas.lahtinen@linux.intel.com">joonas.lahtinen@linux.intel.com</a>> this issue's reproducer: 1) Build this stack: <a href="https://software.intel.com/en-us/articles/build-and-debug-open-source-media-stack">https://software.intel.com/en-us/articles/build-and-debug-open-source-media-stack</a> 2) Run: ./repr.sh and i attached the backported fix patch, so Could you help to tell how to do the next? we need to backport to 4.14 LTS kernel. thanks.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
