Re: [radeonhd] Initial RandR 1.2 support (for the brave of heart ;)

I'm using a ThinkPad T60p (FireGL V5200, 0x71C4), and so far RandR 1.2 support
seems to be working well. I've noticed a few glitches though.

Video Modes:
VGA_CRT1/DAC_A: 1600x1200 @ 75 Hz
PANEL_LCD1/LVDS/TMDS: 1600x1200 @ 60 Hz

- The VGA output seems to have some issues. The right side of the screen isn't
fully displayed (it's around 32 pixels off). Also, there's some ~8px-wide
columns on the screen that appear to be flickering. These columns don't
appear in <1600x1200, though.

- I can't seem to get it so that the VGA monitor is at e.g.
coordinates -1600x0, so it doesn't affect the contents of the LCD. My CRT is
on the left side of my desk where the laptop is on the right, so it would be
useful if I could somehow get the CRT to simply use negative coordinates
instead of having everything move over to the CRT when switching to multiple
monitor mode.

[Actually, somehow I managed to get the LCD indicated as monitor 1 even though
its coordinates are not 0,0, but I'm not sure how I managed this!]

- LVDS doesn't work at resolutions other than native, but I believe that's a
known bug.

I have just pushed initial RandR 1.2 support into the branch
'initial-randr' in the git repository. It's no way sure it will stay
this way (might be completely rewritten), but at the moment everything
looks good.

With the fixes to randr/rrcrtc.c and xrandr.c I just published on the
xorg mailing list this implementation gets through the xrandr testcase
I also published there today just fine.

Still, I would like to have it tested before we even think about moving
this into the master branch, so if you want to try (assuming git 1.5 or
higher, and *hopefully* correct...):

git-fetch origin initial-randr:initial-randr
git-checkout origin/initial-randr
... configure & compile

If you want to work on the branch yourself, better do a
git-checkout -b initial-randr origin/initial-randr

And then please tell me what is working what isn't.

Thanks & Happy Weekend
