Greetings!
I've been having major problems using the atyfb driver with my 8500, and
finally have a clue or two to report.
If I try booting the 2.2.6 kernel from the new beta R5 with an unchecked
"No video driver" and "video=atyfb:vmode:19,cmode:16", I get a frozen
machine and a colored static rectangle on my display. If I use the same
command line, but specify a lower mclk value (most all lower ones work),
the system will boot, but I will get the same types of colored static rectangles.
Recently, I came across a post my Hugy Caley about a "hacked" atyfb
driver from Abe White. I thought I'd give it a try. Using the
parameter line, "video=atyfb:vmode:19,cmode:16", I actually get a
somewhat reasonable display, although the text of the console lines are
repeated several times on each line; every ~25 characters, the line
starts over. Also, the kernel Hugh sent me didn't boot all the way, not
finding my boot device - probably unrelated to the video issue. The
atyfb driver prints out (a close reconstruction from the garbled video):
/bandit, ATY,XCLAIMVRPro atyfb: 3D RagePro(BGA, PCI) 0x479 rev 0x7c 12M
SGRAM 230 MhzPLL, 100 Mhz MCLK
Anyway, I'm not sure where to go from here. I'm a programmer and
willing to jump in, but not knowledgable about device driver debugging.
Any help or advice would be greatly appreciated!
Thanks,
mike.
