Radeon DRI docs?

[RealNC]

Is there some documentation on how to use the radeon DRI kernel driver? Info on what options are supported, how to read temps, how to switch current power state, etc?

On a related note, there's still no mention of "nomodeset" in linus' git kernel-parameters.txt. :P

I don't know about official docs, but the last few posts of this thread will give you examples for switching powerstates, profiles/dynpm, reading temperatures etc.

I can't read temps. In /sys/class, I only have hwmon0 and hwmon1, which are from the coretemp driver (for CPU core 0 and 1 respectively.)

Also, I can't figure out how to get the current clocks/voltages.

And what values other than "default" and "low" are there for power_method and power_profile?

[pingufunkybeat]

power_method is either "dynpm" or "profile"
power_profile is "low", "default", "high" or "auto". "Auto" only makes sense on laptops.

The temp monitoring is not in 2.6.35, you need either the radeon-next tree, or have to wait till the 2.6.36 kernel.

Don't know about clocks/voltages, though it would be interesting to know.

Note that "auto" is not "dynamic clock/voltage adjustment", it just switches to a lower power state when running on battery, and an even lower state when the displays are blanked.
