We know that it loads the radeonsi driver, but.. it doesn't use the driver to render anything by itself, as far as I can understand it... Starting dolphin (or konsole) makes the screen a mess, but I don't know if libGL is to blame for it yet... but what do I know... I got a trace of some sorts from running apitrace, and I've attached it to this posting, but replaying it does not trigger the corruption, and the trace does not contain any frames either. It seems dolphin just loads the radeonsi driver, but what it does with it that triggers the corruption beats me. I have not had time to look into it more today, but I'll try to trace it later like Nicolai suggested on tomorrow (or monday). - Mads On 2016-06-18 21:58, StDenis, Tom wrote: > Hey all, > > Wouldn't "any" apitrace from that version of Dolphin work? Can you get it at all to work with your version of mesa? Once you capture a valid trace once you can replay it in the circumstances you're seeing the VM fault in right? > > tom > > ------------------------- > > FROM: amd-gfx <amd-gfx-bounces at lists.freedesktop.org> on behalf of Mads <mads at ab3.no> > SENT: Saturday, June 18, 2016 09:46 > TO: Nicolai Hähnle > CC: amd-gfx at lists.freedesktop.org > SUBJECT: Re: [amd-gfx] AMD Carrizo - GPU fault detected: 146 0x0842b714 > > On 2016-06-18 14:30, Nicolai Hähnle wrote: > >> Okay, so since dolphin uses OpenGL for rendering as well, the problem >> now is to figure out whether the VM fault comes from dolphin or from >> the compositor. >> >> There are two approaches.
