Description Marcos Souza 2015-12-01 23:23:22 UTC

dmesg

The program app is here: https://github.com/marcosps/experimentations/blob/master/glsl/test_shader.cxx

I just load two shaders and the draw a triangle. The same program works without DRI_PRIME=1.

I already compiled the xf86-video-intel, but I don't know how to setup the new driver in Fedora 23... Can this be related to DRI2?

Please let me know if you you need any additional info.

When requesting the intel driver to use DRI3, I can't see the crashes:

[marcos@localhost glsl]$ cat /etc/X11/xorg.conf.d/30-dri3.conf 
Section "Device"
	Identifier "isrequired"
	Driver "intel"
	Option "AccelMethod" "sna"
	Option "DRI" "3"
#	Driver "modesetting"
#	Option "AccelMethod" "glamor"
#	Option "AccelMethod" "none"
#	Option "ShadowFB" "off"
EndSection


But instead, I get a black window, instead of my shaders...

I'm going to assume the DRICloseScreen in the middle of the stack is just the unwinder getting confused and so this looks like a nouveau bug and not a core DRI2 bug.

So, in this case, there is a start point to look at to solve this problem? I would like ot help fixing this issue...

Thanks,
