lib/interval_tree: fast overlap detection

2017-09-09T01:26:49Z

Allow interval trees to quickly check for overlaps to avoid unnecesary tree lookups in interval_tree_iter_first(). As of this patch, all interval tree flavors will require using a 'rb_root_cached' such that we can have the leftmost node easily available. While most users will make use of this feature, those with special functions (in addition to the generic insert, delete, search calls) will avoid using the cached option as they can do funky things with insertions -- for example, vma_interval_tree_insert_after().

drm/radeon: make radeon_mn_get wait for mmap_sem killable

2016-05-24T00:04:14Z

radeon_mn_get which is called during ioct path relies on mmap_sem for write. If the waiting task gets killed by the oom killer it would block oom_reaper from asynchronous address space reclaim and reduce the chances of timely OOM resolving. Wait for the lock in the killable mode and return with EINTR if the task got killed while waiting.

drm/radeon: fix userptr lockup

2015-05-07T15:00:15Z

We shouldn't try to reserve and wait for a BO that isn't bound. Otherwise we can run into a deadlock if we have a fault during binding the BO. Signed-off-by: Christian König Signed-off-by: Alex Deucher

drm/radeon: allow creating overlapping userptrs

2015-04-13T15:17:59Z

Similar to the Intel implementation, but instead of just falling back to a global linear list when we have an overlapping userptr request we accumulate all overlapping userptrs in a local list. Signed-off-by: Christian König Signed-off-by: Alex Deucher
