<chewitt> something in mesa master completely broke Kodi support, could be in the last week, I didn't find time to bisect it yet
<chewitt> it throws major GPU faults and the screen remains dark, no GUI
<icecream95> chewitt: Could you upload an apitrace of it?
<chewitt> if you explain how to make one
<icecream95> chewitt: Are you running it in a windowing system or from a VT?
<chewitt> Kodi runs on the framebuffer, so VT
<icecream95> An apitrace won't be that useful, then...
<icecream95> Maybe if you compile Mesa with --buildtype=debug it will fail an assertion, which will make it easy to see what went wrong

<chewitt> probably easiest if I bisect and find the problem commit
<chewitt> but this takes time

<icecream95> chewitt: Running it with 'PAN_MESA_DEBUG=sync 2>/tmp/trace.txt' will give you a file with a dump of the jobs that cause faults
