some segfaults
This is an initial report no bisects as I have no clue when it started yet.
It seems there is an unlucky timing situation with kodi that may segfault
radeonsi or lock gpu playing videos with vdpau h/w decode + temporal vdpau
deint which is default kodi settings.
I can't reproduce with mplayer or mpv.
It seems to need HD interlaced + deint, but that may be just because it changes
timing.
Running with VDPAU_TRACE=1 so far avoids the crash/lock, as does setting cpus
to perf.
Running kodi git, but it's reproducable with 11 month old git as well.
It's easiest to provoke starting kodi with a file on command line, but is
possible starting from running kodi menu - possible improved chance of
crash/lock by moving mouse after clicking file to make overlay instantly render
over video.
Attaching some segfaults and locks.
I am running git mesa/llvm/kernel and the crash is rare enough that I may have
missed it for ages given the amount I test kodi. Additionally the best way to
provoke = repeated command line start, only started being possible again
ecently due to a kodi bug.
The segfaults are a bit random.
