freebios1 sis-kernel_patch for 2.6

[Thomas Wehrspann]

Hi,

i'm still using the K7SEM Motherboard with DiskOnChip Milleniuim an LinuxBIOS.

Linux 2.6 has some features i need and want, so i ported parts of the latest 
2.4 sis-kernel_patch and the ide-spinup.patch to the 2.6 kernel some time 
ago.
I combined both patches into one.
I didn't port the SiSFB-Lite part of the SiS-Patch, because the SiS graphics 
driver  in the kernel changed a lot.

The SiS framebuffer seems to work better with kernel 2.6 and linuxbios than it 
was with kernel 2.4 and linuxbios. But i have to call the fbset utility first 
after booting with linuxbios.
I do not have the knowledge to fix that.

Greetings
Thomas Wehrspann

Ollie Lo would be the person to ask about that. He's on leave at the 
moment, visiting with relatives. Please wait patiently for his respnose if 
nobody else can help.

I can't help him with the 2.6 frame buffer neither. That driver is based
on the "official" framebuffer driver released by SiS long time ago. It 
uses register table from vga bios image so there is a lot of code doing
table parsing. It is totally beyond my knowledge.

Unfortunately, that driver is not maintained by SiS any more. You 
probably should ask the independent maintainer Thomas Winischhofer

But after setting the videomode with fbset (the same mode that should be set 
after booting) framebuffer works. So i hoped it can't be that difficult.

Are you sure about the "official" SiS driver? For me the 2.6 SiS driver seem 
to be nearly the same Thomas Winischhofer released on his site. And he stated 
that he had no help from SiS.

I got that problem for my SiSFB Lite too. On some version of the VGA 
core, it take two set modes to actually set the hardware to the correct
vide mode. Probably you can try the same trick.

He based his code on a very old "official" SiS release. SiS lost their 
interest in supporting that stuff after a few public releases and pretty
much abandoned it. I am really amazed that he could figure out their
code without any support from SiS (and persisted for such a long 
period).
