Details

After upgrading Mesa from 20.1.8 to 20.2.0, Zink is not available anymore. I've tried to query the driver information, but it seems it is not supported in the build anymore.


Additional info:
- Mesa 20.2.0

Steps to reproduce:
- MESA_LOADER_DRIVER_OVERRIDE=zink glxinfo
This task depends upon

Strange. My GPU is a AMD Radeon VII (VEGA20) with RADV and I get a memory access error.

It works with my RAVEN AMD APU. Except for glxgears32 where I see the message "libGL error: failed to load driver: zink" as well.
Comment by Magnus Boman (katt) - Wednesday, 07 October 2020, 12:09 GMT
It not working with glxgears32 is as expected, since lib32-mesa isn't built with zink.

Thanks for the explanation, I didn't expect that it is build only for the 64bit package.

I've done another test with my Intel HD5500 notebook and there it doesn't work either, just like with VEGA20.

why not to build mesa 32 bits with zink too?
I think many opengl games need them..
