Description ddfs 2012-05-11 05:31:25 UTC
cat /sys/kernel/debug/dri/0/radeon_pm_info is reporting default clocks at 400/900 mhz.
Changing power profile to high (which is actually 725/1000 according to bios) only increases the voltage, but clocks are still limited at 400/900.
Also, these values 400/900 match only UVD mode in the graphics card bios.
I suspect the driver uses incorrect bios readings, because the default "boot" value is 725/1000 for my HD5850.

Please attach a copy of your vbios.

(as root)
(use lspci to get the bus id)
cd /sys/bus/pci/devices/<pci bus id>
echo 1 > rom
cat rom > /tmp/vbios.rom
echo 0 > rom

Any updates on this? Did the attached bios help?

Overclocked Radeon HD 5850 BIOS

Same problem here. The only difference is in vendor of videocard and frequencies(I have HIS Radeon HD 5850 with 850/1200, BIOS attached). System uses only limited 400/900(399990 kHz/900000 kHz to be correct).

kernel: 3.3.6
xf86-video-ati: 6.14.4
