In this case just install the firmware and reboot, DRMDEBUG isn't going to help and is overly verbose unless a few things are turned off. There is no 2d or 3d acceleration with radeonsi parts like pitcairn however because it requires a version of EGL with the drm/gbm platform instead of the x11 platform, the glamor library and a version of mesa compiled with llvm as the mesa radeonsi driver has a hard dep on llvm. I attempted to provide alternative paths to the linux only udev code in libgbm and co but didn't end up with a useable X session when testing glamor on a northern islands card. AMD don't support the usual xorg type acceleration for radeonsi, only glamor. And sadly it seems the mesa/3d driver is unuseable without glamor as well...
