RV630 KMS PM info on tables requested

Tue Apr 27 02:35:09 PDT 2010

I sent this to Alex a few days ago but felt I should post it on this
list as well:

I've been testing radeon KMS PM with 2.6.34-rc* for a few days now and
I wanted to send you my testcase. Even though PM is enabled, the
defaults of my card are somewhat insane so no real powermanagement
takes place - i.e. the card doesn't get clocked down. is there any way
to force the card to use a different setting where less power is being
consumed?
Thanks!

Klaus

Below you'll find the output of dmesg | grep drm which should provide
you with the needed information:
