Is this a regression? Was dpm working previously at some point, if so when?

Alex, I want to check this. What should I start from? You added si_dpm.c at 2013-06-27 (https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/drivers/...). Were there another system to change power management before? Is it enought to find first stable version available in ubuntu repo with si_dpm.c? Or should I use kernel from git and start bisect by history of si_dpm.c?

It worked fine in 3.11 and 3.12. The problem appeared somewhere during the development of 3.13. At those point vgaswitcheroo didn't work and I had to stick to older versions of the kernel.

There are no errors and no success in changing power_method. Where did I do mistake?

We don't support changing between dpm and the older methods dynamically. When you enable dpm, you can't switch to the older pm methods.

--- Comment #13 from Arek Ruśniak arek.rusi@gmail.com --- in my case it's error message in dmesg output only, performance is pretty the same.

--- Comment #15 from Arek Ruśniak arek.rusi@gmail.com --- yes it does. dmesg doesn't show "[drm:si_dpm_set_power_state] *ERROR* si_set_sw_state failed". i've tested it on mainline tree
