Summary: Power management not working on ATI M92 LP [Mobility Radeon HD 4300] Product: DRI Version: unspecified Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: s.j.turner@uqconnect.net
A launchpad user reports "If I deactivate the ATI restricted driver, and then restart my computer, GPU temp is between 70-80 degrees Celsius instead of the usual 40-50, without doing anything, no application running, no effects."
lspci -nn | grep VGA 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc M92 LP [Mobility Radeon HD 4300 Series] [1002:9552]
MachineType: Hewlett-Packard HP ProBook 4710s
This was originally reported on Ubuntu 9.10 "Karmic Koala" with a 2.6.31-based kernel (which of course does not have power management support), but persists on an Ubuntu 11.04 "Natty Narwhal" pre-release with a 2.6.38-based kernel.
The problem is that this user reports "I've tried setting the power (management) profile settings and dynpm, but nothing has changed, still running above 70 degrees Celsius."

--- Comment #2 from Xavier Bestel xavier.bestel@free.fr 2011-04-05 06:38:42 PDT --- FWIW, I'm using this card: 01:00.0 VGA compatible controller: ATI Technologies Inc RV630 [Radeon HD 2600 Series] Under Debian's 2.6.38-2-amd64, and the temperature is currently 74°C according to the "sensors" command, and the card is nearly too hot to touch. I've never tried the proprietary driver.

--- Comment #3 from madbiologist s.j.turner@uqconnect.net 2011-04-05 06:49:16 PDT --- Xavier - do the dynamic or profile-based power management settings work for you? This bug is about those settings not working.
If I understand things correctly, a hot GPU is to be expected when using the open-source driver without these settings.

--- Comment #5 from Xavier Bestel xavier.bestel@free.fr 2011-04-05 07:02:31 PDT --- Alex,
I read that page (didn't know it had something more useful than the progress table, thanks), and did a subsequent: echo low >/sys/class/drm/card0/device/power_profile
Now it looks like my pc has deadlocked. I didn't get a prompt after that command, and all network connexions are stuck. I'll reboot it when I'm back home (the pc is at home, I'm at work), but in the meantime it means no more mails for me (it's also my mail server). I'll try to follow the bugzilla in the remaining time.

This is an HP 4720s notebook. I have tried both "dynpm" and "low" settings, and while it does not lock up, it still runs hot - 60+ degrees, fan constantly on high.

--- Comment #9 from leonardo generic@bsod.eu 2011-07-13 13:09:19 PDT --- I have the same card on DELL Studio 15". I wouldn't say that power management does not work. I'm using "profile" method with "low" setting. After about ~20 mins of uptime this is the "sensors" output:
acpitz-virtual-0 Adapter: Virtual device temp1: +57.0°C (crit = +100.0°C) temp2: +58.0°C (crit = +100.0°C) temp3: +65.0°C (crit = +100.0°C)

With "mid" setting temp goes beyond 70° C, and sometimes I experience GPU lockup when playing with heavy graphics (e.g. Flightgear simulator):
[ 4357.360138] radeon 0000:01:00.0: GPU lockup CP stall for more than 10000msec [ 4357.360189] GPU lockup (waiting for 0x0007476B last fence id 0x0007476A)
Radeon pm feature are just not enough aggressive. With fglrx driver radeon-pci-0100 temp stays well below 60° C and fan doesn't run all the time.
Unfortunately Radeon driver isn't really usable for me on my laptop, but thank you for improving it. Fglrx driver isn't really an alternative for me.

--- Comment #10 from sashker sashker@inbox.ru 2012-05-14 18:59:05 PDT --- I have same problem with my Acer 4810TG notebook. The average temperature - is 70 degrees C. With proprietary driver - the temperature is 35-40 degrees C.
#lspci -nn| grep VGA 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc M92 LP [Mobility Radeon HD 4300 Series] [1002:9552]
#uname -a Linux 3.3.4-4.fc17.x86_64
#cat /sys/kernel/debug/dri/0/radeon_pm_info default engine clock: 450000 kHz current engine clock: 299530 kHz default memory clock: 600000 kHz current memory clock: 299250 kHz voltage: 900 mV PCIE lanes: 16
I'd tried to use dynpm and profile (low) options, but it doesn't help me.
I am willing to help with testing of the solution. A lot of people complain about the heat when using the open driver that causes them to use the proprietary driver.
