Any guess? May be vbios doesn`t have correct states information? Or may be its my fault and i don`t set some kernel options?
The vbios has the same clocks for every power mode.
It`s sad :( I hope you have any plans to advanced power management system to avoid exceptions like this. May be someone can edit this page http://www.x.org/wiki/RadeonFeature about wrong bios information to help another people with same issue. Anyway, thanks for the help.
Hello, how about making some handler to exceptions of the rules? I know there many wrong state info in video cards vbios. As i know we will not see kosher power management for a long time, so this may be not so bad solution for users at the moment. What developers think about this? Sorry for my English, i hope you understand what i mean.
radeon has got some new power management infrastructure: http://www.botchco.com/agd5f/?p=57 Does that change anything wrt this bug? Btw. here: # uname -a Linux hier 3.11.0-rc1 #2 SMP Sun Jul 21 12:29:18 CEST 2013 x86_64 GNU/Linux (booted with radeon.dpm=1) # lspci | grep Radeon 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
