Hey,
I've just committed the last part of the work I started during g2k12 and
I would really appreciate some more tests before enabling drm(4) on
macppc.
- First of all you need a machine with a G3 or G4 processor and a Radeon
graphic card.
- Then update your source tree to -current and make sure it is current
enough (you must have /sys/dev/agp.c rev 1.36).
- If you don't have them already, make sure to create /dev/agp0 and
/dev/drm0 using the appropriate MAKEDEV(8).
- Start by building a GENERIC kernel and make sure it works as expected.
- If everything went fine, you can now muild a custom kernel with:
#option DRMDEBUG
radeondrm* at vgafb? # ATI Radeon DRM driver
drm* at radeondrm?
After rebooting, start X and enjoy! If X starts correctly, please look
at your Xorg.0.log, if it says something like:
...
[ 908.296] (II) RADEON(0): AGP card detected
...
[ 908.499] (II) RADEON(0): [dri] Found DRI library version
1.3.0 and kernel module version 1.31.0
...
[ 909.542] (II) RADEON(0): Direct rendering enabled
you should be using accelerated video using the DRI ;) Now the usual
test program is:
$ glxgears -info
If it works for you, I would be pleased to hear it, otherwise try to
rebuild a custom kernel with the DRMDEBUG option and send me your
dmesg, Xorg.0.log and /var/log/messages with the drm vomit in it.
Some known issues:
- If you cannot see some fonts in your favorite gtk application, you
need to update to a more recent xenocara snapshot or at least update
and reinstall the xf86-video-ati driver.
- Sadly, OpenGL does not work with our UMS drivers see the links below
for more information:
https://bugs.freedesktop.org/show_bug.cgi?id=26496
https://bugs.freedesktop.org/show_bug.cgi?id=37166
- With some of my PowerBooks (with r300), the console is not restored
correctly when exiting X.
Finally if you test this stuff, I would like to know which AGP revision
and graphic card you are using, please include the output of the
following command in your report:
$ dmesg |grep -e "^vgafb" -e "uni-n rev"
