Radeon DPM Support Should Now Be In Good Shape

[edoantonioco]

Is this going to be enabled by default in kernel 3.12? I cant wait

Kernel 3.11 already has full dpm support, you have to add "radeon.dpm=1" to the kernel command line.

Then that wouldn't be enabled by default, now would it?

Thanks for the info , but seems to be than I have more FPS in games like team fortress 2 and portal having this feature disabled, so, now I have it disabled
(my GPU is Radeon HD 4200). Thats weird.

Did you download the appropiate firmware and put it in /lib/firmware/radeon ?
Run dmesg | grep dpm in terminal, if it failed to intialize then you need the right ucode...

I'm not sure which you should d/l... Seeing how you have a HD4000 series card you should download:
RV710_smc.bin
RV730_smc.bin
RV740_smc.bin
RV770_smc.bin

and put it all in /lib/firmware/radeon
Then reboot and run dmesg | grep dpm to verify if DPM intialized.

@agd5f or bridgman

Is the code that controls the fan speed of the card in the firmware or in mesa/kernel/somewhere open? I am just curious about something

Thanks in advance.

It depends on the card. The gpu has a built in fan controller. If the oem uses that, it's controlled by the fan controller hw. If the oem uses an external fan control chip, that controls the fan. The vbios loads a default fan profile when the asic is initialized. It raises the fan speed as the temperature increases and reduces it as the temperature decreases. There is no support for manual fan control at the moment.

Thanks for the answer. I was just curious about the control algorithm of the thing.

I would love to use this feature as my card (ASUS EAH6870 DirectCU/2DI2S/1GD5) is really noisy but it freezes my PC when enabled and the monitor goes to sleep mode.
If I have radeon compiled as module and firmware in /lib/firmware/radeon freez occurs when the module loads and if I have it with firmware in kernel freez is right at load of kernel.
I have enabled intel integrated card to see if there is any output but there is nothing on the screen.
Do I need more than radeon module and firmware from http://people.freedesktop.org/~agd5f/radeon_ucode/ ?

Screen blinks from time to time. But thats rare. Not sure if its driver related or something else.
