Re: [BUG] crystalhd git.linuxtv.org kernel driver: unable to handle kernel paging requests, improper (spin)locking(?) and paging

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

I actually am one of the few that has one of those decoders so should be able to test things when needed. Just let me know what to test and I will try to comply

Hello guys,
I'm working on supporting BCM 970012/15 crystalhd decoder in userspace video/tv apps and 

can't find where to report bugs of

http://git.linuxtv.org/jarod/crystalhd.git
<devinheitmueller> I think he just borrowed our git server.
So I borrow this list to get more developers, testers and sw- quality guys in.
Forgot to mention the attached Oopses under high load and "multithreading" in half automated stress/mass testing. 

Scenario e.g.:
Dec 29 15:58:29 vdr1 kernel: [ 5698.364950] crystalhd 0000:02:00.0: Opening new user[0] handle Dec 29 15:58:30 vdr1 kernel: [ 5698.557932] crystalhd 0000:02:00.0: Opening new user[0] handle Dec 29 15:58:30 vdr1 kernel: [ 5698.846312] crystalhd 0000:02:00.0: Close the handle first..
Looks like the driver is not "threadsave", rebuilding kernel with spinlock debugging, should show more up.
