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)
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +53.0°C (high = +90.0°C, crit = +90.0°C)
coretemp-isa-0001
Adapter: ISA adapter
Core 1: +55.0°C (high = +90.0°C, crit = +90.0°C)
radeon-pci-0100
Adapter: PCI adapter
temp1: +69.0°C
# cat /sys/kernel/debug/dri/0/radeon_pm_info
default engine clock: 500000 kHz
current engine clock: 219370 kHz
default memory clock: 800000 kHz
current memory clock: 299250 kHz
voltage: 900 mV
PCIE lanes: 16
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.
