The Linux 2.6.36 Kernel Will Have Some Fun DRM

Originally posted by bridgman View PostFor the next generation GPUs I think the approach will be roughly :

- build a sufficiently detailed list of EG->next gen changes so we can have a good idea how long adding support will take
- go bug the internal PMs to make sure we know when new parts will launch
- make sure we/community can port Evergreen support to 600g quickly enough to keep a reasonable schedule
- make sure that distros will be able to ship the Gallium3D driver even if it's still a bit rough and they're still shipping classic for earlier HW
- if all of the above seem OK, go with the Gallium3D driver from day 1
- if any of the above seem like a problem, do initial support on the classic Mesa HW driver then jump across to Gallium3D after
Thanks very much!

I'm using an Radeon 5850(R800/Evergreen) on Maverick Alpha 3+updates.
I've tried to get last drivers/DRM using http://kernel.ubuntu.com/~kernel-ppa/mainline/ 2.6.36-RC1 kernel and https://edge.launchpad.net/~xorg-edgers/+archive/ppa drivers... But seem works like before... very basic support, tearing, no 2D acceleration.
I need to modify something on xorg.conf?
This is an Ubuntu-test-box, no problem if go wrong :P

The desktop parts can still enable clock gating (turning off parts of the chip dynamically) with the poorly named dynclks parameter. I should really move that to sysfs as well.
Yet, /sys/class/drm/card0/device/power_method is missing.

Are you running KMS, and do you have 2.6.35 or higher kernel ?

I think that's because, as agd5f already stated, your Radeon x1600XT vbios lacks any information about other power states, due to the management of the card's power states by means of other external components, like the two programmable PWM controllers you have on the back of the PCB.
