How do I turn on the debugging information and output the printed message to the log?
-os:ubuntu20.04 -GPU: amd vega 64 -kernel version: 5.11.0-13.14 -Mesa version:21.0.1
I got the source code of 21.0.1 from the launchpad of ubuntu and compiled it into a deb package for installation.
We have a problem in the test that requires mesa debugging information.
I have set the following environment variables, but unfortunately, it does not take effect
export MESA_DEBUG="1,context"
export MESA_LOG_FILE=/home/xxx/mesa.log
export LIBGL_DEBUG=verbose
