[Linux-fbdev-users] Atyfb - Mach64 Rage Mobility linux 2.6 kernel support

[cga <cg...@gm...>]

The 2.4 version of the atyfb framebuffer driver works great at my old 
laptop's native 1400x1050 resolution.

I have experimented with linux kernels 2.6.8 and 2.6.12 with the 
"video=atyfb:1400x1050" boot param and this only gives me a black screen.

I assume that the Rage Mobility chip is not supported at this point by 
the 2.6 version of atyfb (?).

Will this be provided in the future or has support for this old chip 
been dropped altogether..?

Thanks.

There is an option CONFIG_FB_ATY_XL_INIT which is broken. For many
Mach64 cards it won't work if set to "y". Try stting
CONFIG_FB_ATY_XL_INIT=n in your kernel config, and recompile, it should
work. This option will be or already is removed in 2.6.16 kernel, so
when that one is released it should work 'out of the box'. Also in the
latest Debian sid/unstable kernel from package linux-image-2.6.15-1-686
version 2.6.15-7 it is already removed and ATI Mach64 works OK.

Great news..! I may need some time to confirm it works ok with my 
particular chip due to hardware problems.. I need to install a 
replacement keyboard on the laptop which hopefully should get here some 
time this week..

I'll keep you posted.
