I have a working direct rendering mechanism in my 64-bit userland. However, 32-bit software running in a 32-bit chroot environment cannot operate with the 64-bit drm. I get the following error when executing the 32-bit glxinfo inside the chroot:
# /usr/X11R6/bin/glxinfo name of display: :0.0 libGL error: failed to open DRM: Operation not permitted libGL error: reverting to (slow) indirect rendering display: :0 screen: 0 direct rendering: No
This generates the following entry in kernel messages:
Jul 20 21:18:46 gordon ioctl32(glxinfo:12562): Unknown cmd fd(4) cmd(c0086401){00} arg(bffff0f0) on /dev/dri/card0
Similarly for the 32-bit glxgears:
Jul 20 21:21:21 gordon ioctl32(glxgears:12567): Unknown cmd fd(4) cmd(c0086401){00} arg(bfffeff0) on /dev/dri/card0
