$ cat /sys/module/radeon/parameters/dpm
-1
I verified with
$ dmesg | grep -i "command line" && cat /sys/module/radeon/parameters/dpm
[ 0.000000] Command line:
BOOT_IMAGE=/vmlinuz-3.16.0-rc6-citadel+fdo-att-104101
root=/dev/mapper/citadel--vg-vol--root ro quiet
[ 0.000000] Kernel command line:
BOOT_IMAGE=/vmlinuz-3.16.0-rc6-citadel+fdo-att-104101
root=/dev/mapper/citadel--vg-vol--root ro quiet
that I removed the radeon.dpm=1 from the kernel command line before booting.
Kernel version is Git:~agdf5/linux:drm-next-3.17-rebased-on-fixes:fa78380797 +
