Power management isn't the next step on the roadmap: we have to handle
i915 and the device-independent part before upgrading the Radeon driver
again.
We also need to work on vt(4), the new console driver. This will help
with moving on with the "NEW_XORG" stack (which is getting old...).
If you're willing to help and are interested in kernel development, you
could look into either problems with the GPU drivers or missing features
in vt(4). Here are some ideas:
1. With Radeon cards, Piglit, the Mesa testsuite, freezes at some
point. This is 100% reproducible on my laptop and this is always
with the same tests. You would need to run Piglit (all
dependencies are in the ports tree, except piglit itself which
evolves too quickly to deserve a port).
2. With either Radeon or i915, when we vt-switch from the console
back to the X session, the screen is frozen for up-to 10". It
looks like we don't restart something and a timer implicitely
does it.
3. In vt(4), we are missing several features. Here are two which
were requested by testers (there are probably other requested
features of course):
o text cursor blinking
o vidcontrol -[hHpH]
Playing with vt(4) is probably easier to start with if you never did
kernel development, as the code is way simpler and shorter than the DRM
component.
Let me know if you want to work on this!
