Newbie question…
I’ve been investigating a regression in Fedora 25 between mesa-dri-drivers versions 12.0.3 and 13.0.3 (https://bugzilla.redhat.com/show_bug.cgi?id=1426549).
The output with the Fedora version of Mesa is:
GL_RENDERER = Gallium 0.4 on virgl
So virgl is enabled and working in this VM.
When I build Mesa from sources, and configure it with “—with-galium-drivers=virtgl”, I get this from glxgears -info:
GL_RENDERER = Gallium 0.4 on llvmpipe (LLVM 3.5, 128 bits)
GL_VERSION = 3.0 Mesa 17.1.0-devel (git-ccb70d6)
GL_VENDOR = VMware, Inc.
I also built 13.0.3, I had to add —with-egl-platforms=“drm”, but the renderer is still wrong.
Where can I get information about why Mesa selects this or that renderer? I tried enabling LIBGL_DEBUG, but I don’t get much more information. I’m in the process of adding a few log entries in loader.c to understand what’s going on, but if there is a better way, I’d be happy to use that instead.
Thanks
