[gentoo-kernel] Kernel configuration and DRI.

Hi. you might know me from the forums, but unfortunately I've appeared to
have stumbled over a difficult problem -

http://forums.gentoo.org/viewtopic-p-6487475.html

I'm having a bad time configuring the kernel. I've enabled KMS (like what's
with Debian), used the latest xserver, mesa from the overlays and eselected
mesa to galium (r300 and sw). On this setup, glxgears is blank... the's just
a blank windows with no reading of the fps drawn.

On the other hand on Debian I get a sustainable FPS, if I copy over the
Debian kernel (and modules) to my Gentoo install, I get good FPS, so there
must been something wrong with my kernel configuration. The Debian guys have
enabled KMS.

RS690m chipset which hosts x1270.

You can copy the ".config" from the debian kernel into the
gentoo-kernel, run "make oldconfig" and see if that takes you in the
right direction.

Good luck,
Daniel

:D
Apparently it will be easier to just enable/disable options that I just
'feel' might be causing the issue.

I've a very minimal config of the kernel (very much trimmed out), that means
the kernel + module size is around a fraction to that of Debian.

Better to copy ".config" and to use diff with your gentoo .config

The difference is too large.

One more set of success. Better performance with the classic mesa BUT with
KMS enabled using the Debian kernel and it's config.

Still not reproducible with my custom config.

Is there a way to just see which things the radeon KMS driver expects... and
certain messages if they are not found?

Have you checked dmesg, and "/var/log/Xorg.0.log"?

Nope.

The Debian kernel produces this extra -

[   481.338] (WW) RADEON(0): You need a newer kernel for sync extension

Otherwise both complain about vesa and fbdev not present.
