How To Setup Radeon DPM On Ubuntu Linux

[brosis]

radeon.dpm=1

may not work with a Debian stock kernel--or any kernel that uses radeon built as a module, unless there's some special magic in your init version.

ghost@linux:~$ cat /boot/config-3.11-6.dmz.1-liquorix-amd64 |grep -i drm_radeon
CONFIG_DRM_RADEON=m
# CONFIG_DRM_RADEON_UMS is not set
ghost@linux:~$ dmesg|grep -i radeon|grep -i dpm
[drm] radeon: dpm initialized
ghost@linux:~$ cat /boot/grub/grub.cfg |grep radeon.dpm
	linux	/boot/vmlinuz-3.11-6.dmz.1-liquorix-amd64 root=UUID=9ae35c45-c420-43e0-bf40-1dbe3f6882e6 ro quiet radeon.dpm=1

This is standard Debian Testing.

radeon.dpm=1

may not work with a Debian stock kernel--or any kernel that uses radeon built as a module, unless there's some special magic in your init version.

module.parameter=value

is only for builtin modules, to the best of my knowledge.
So you would need to do something like:

echo "options radeon dpm=1">>/etc/modprobe.d/radeon.conf

If you want a lower clock, see if you can use the "battery" state.

Radeon is almost always built as a module and dpm works with the Debian stock kernels and it should work in any circumstances if radeon.dpm=1 is passed to the kernel boot options.

This is the relevant line in dmesg to see if dpm is actually activated:

[    7.075704] [drm] radeon: dpm initialized

You can see it with the following command:

dmesg | grep " dpm "

BTW there is the clock utility on the other thread here, you should try it.

Say,.. why do you have a habit of answering exactly the same post, at exactly the same time with almost identical answer D

effective power management with DPM?

I have a question concerning this DPM thing:
I think I managed to set everything up correctly on my 3.12.6 kernel (at least, so it seems).
I have a RV710 in my laptop (mobile radeon 4570)
DPM talks about 7 different profiles..
but when I switch from battery - balanced - performance using this command:

echo (profile) > /sys/class/drm/card0/device/power_dpm_state

and monitor the frequency information with this tool:

while(true) do sleep 5; cat /sys/kernel/debug/dri/64/radeon_pm_info; done

I see no difference at all; I tried:
- doing nothing in KDE
- doing nothing in XFCE
- running glxgears
- decoding a h264 movie using mplayer and vdpau

and for every profile, I came to the conclusion: the max performance is 680mhz core and 500mhz memory, and minimal is 220 mhz core and 250 mhz memory
test was done on AC power

[Gloomwing]

You don't need any new ucode for power management on that chip, but you still need the ucode for the CP, RLC, and UVD.

Well i do not get it. So what do i need, where to get it and how to install it? (or tell me where to read about, please)

I have AMD A4-4355M APU (hate it) on Samsung NP535U3C (do not like it too...).

I use quite recent version of kernel (3.14.7-031407-generic #201406111644 on Mint 16), Gallium 0.4 on AMD Aruba, Mesa 10.3.0-devel
Drivers are from Xorg-Edgers PPA.

I have installed linux-firmware so ARUBA*bin are present.

My dmesg is quite long so i had to cut it off... alot:

What else can i do?
Some people reports power ussage for about 0.5%/min, while i, forcing cpu to stay at lowwest speed can get usually 0.9-1% per minute.

Please help!

Sorry for splitting posts, but it was too long =/


----------

Jsollie, there is a diffrence, for example (from Your log):

[    2.667173] == power state 0 ==
[    2.667175]  ui class: none
[    2.667178]  internal class: boot 
[    2.667180]  caps: video 
[    2.667182]  uvd    vclk: 0 dclk: 0
[    2.667185]          power level 0    sclk: 68000 mclk: 50000 vddc: 1200
[    2.667186]          power level 1    sclk: 68000 mclk: 50000 vddc: 1200
[    2.667188]          power level 2    sclk: 68000 mclk: 50000 vddc: 1200
[    2.667189]  status: c r b 
[    2.667191] == power state 1 ==
[    2.667192]  ui class: performance
[    2.667194]  internal class: none
[    2.667195]  caps: single_disp video 
[    2.667198]  uvd    vclk: 0 dclk: 0
[    2.667199]          power level 0    sclk: 22000 mclk: 25000 vddc: 950
[    2.667201]          power level 1    sclk: 30000 mclk: 50000 vddc: 950
[    2.667202]          power level 2    sclk: 68000 mclk: 50000 vddc: 1200

at 0 (boot) Your gpu is forced to use maximum (or high) frequency at all level while on 1 (performance) it cat switch from high sclk(clock) to low (and change vddc too - voltage i suppose).
