Hi Dave, I've been running with lockdep with these changes for over a week now. Just ran another test with our daisy-chain displays and the 4k tiled display with no deadlocks or lockdep prints (other than "RCU lockdep checking is enabled."). Thanks, Harry ________________________________________ From: Dave Airlie <airlied@xxxxxxxxx> Sent: Sunday, January 24, 2016 11:53 PM To: Wentland, Harry Cc: dri-devel Subject: Re: [PATCH 0/5] Fixes for MST (daisy-chain and 4k tiles) On 23 January 2016 at 08:07, Harry Wentland <harry.wentland@xxxxxxx> wrote: > A couple of MST fixes to bugs in the framework that we encountered when > testing with > - three-display daisy-chain configurations > - 4k tiled displays Hi Harry, these all look pretty good to me, have you tested them with lockdep enabled? I had started to fix the CSN/GUID one here a little while back but it's sitting on a laptop I can't access at the moment. But if you can test with lockdep, and it doesn't deadlock, then I'm happy to accept these..
