X.org 7.0 + direct rendering

[hookdonspeed]

this is my first time attemting Xorg on a sparc system, and i cant seem to get direct rendering to work
ive done everything "I" can think of, i havent realy touched linux too much lately, so i was hoping someone could help me

i have a sun ultra 2 2x300mhz, 256ram, creator3d video.

im using X.org version 7.0 and kernel version 2.4.32-sparc-r2
dri is enabled in the kernel.

glxgears is running at about 120fps

glxinfo (choped down a bit)

name of display: :0.0
display: :0 screen: 0
direct rendering: No
server glx vendor string: SGI
server glx version string: 1.2
client glx vendor string: SGI
client glx version string: 1.4
GLX version: 1.2
OpenGL vendor string: Mesa project: www.mesa3d.org
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 (1.5 Mesa 6.4.1)
glu version: 1.3


here is my xorg.conf

Direct rendering for the Creator is disabled in all current versions of xorg-x11 (6.8.2-r7, 7.<anything>). The code in the sunffb driver to support it is not compiled (it's disabled with {#if 0 ... #endif} blocks). According to David Miller (davem), one of the authors of the driver, it is not possible to do both direct rendering and correct font rendering, and correct font rendering seems the better choice.

That said: As you noticed, openGL works fine with Creator, but it always goes through Mesa indirect, no matter what you do. As a consolation, xaa (2D acceleration) is now supported.

We do not know any way around this, especially because in 2.6 kernels, DRM for the ffb will not build anyway (errors at compile time). I hope this helps answer your question, however.

Ferris
