Linuxppc developers,
I am attempting to get pci vga working on the sandpoint platform
using dink32 to start linux. I have tried several S3 cards with no video
success. The kernel has vga driver support for SIS and ATI support, but
these are classified as experimental and will not compile, undefined
externals for __floatsidf, __divdf3, __adddf3, __fixunsdfsi, __muldf3, and
__vmalloc.
I have written dummy routies for these functions, compiled it
successfully, and I can get linux to recognize it has an SIS 300 card, the
one I'm using, but it still does not work and in fact crashes if I use
XFree86, via startx. My vmalloc code attempts to allocate space from an
array I have declared in the code space. I have also attempted to allocate
code from video space at 0xb0000000, but this also crashes.
Can anyone tell me what these functions do, and/or where I can get
the code for them?
Has anyone succesfully used vga on a sandpoint, and if so, can I get
the code and and the model of the pci video card used?
I'm also getting a timeout on the AT keyboard, however, it works
fine under dink32.
I am using 2.4.21-rc1 kernel.
these are the messages I get. The vmalloc and ivideo messages are
mine.
