I am working with a SBC (mediaGX+CS5530). I am looking for the
framebuffer driver that can running successfully. I am using kernel
I had tried some ways:
1) using the native driver on the website of National-Semi, but I
found in its code:
/* If we are in hires mode, get that mode */
if (screen_info.orig_video_isVGA != VIDEO_TYPE_VLFB)
When booting on my SBC, the value of orig_video_isVGA is 1, not
VIDEO_TYPE_VLFB(0x23), so the initialization can not go on.
2) I found that someone had said that the vesafb could work using
"vga=0x303, video=vesafb", but I also found that in the code for
vesafb, the orig_video_isVGA also would be checked.
3) I found that Alan Cox had written a drive for mediagx in 1998, but
after I looked through the code, I guess it was written for kernel 2.2
or even older, because the pci structure used there is not for kernel
There are so many kind of SBC using Nation-Semi GX processors on the
market, but I have not found a working framebuffer driver for almost
one week, can someone here help me?
