After upgrading to 6.8.1, direct rendering stopped working. According to
the X logfile, direct rendering is enabled:

Note especially this last line.

Nevertheless, when I run glxinfo, it returns:

I did upgrade dri: pkg_info |grep dri-
dri-6.2,2           OpenGL hardware acceleration drivers for the DRI

Do I have to take some special steps to get direct rendering when
upgrading?

Note that the AGP and radeon_drm drivers are included in the
kernel. dmesg says:
