I noticed that there was some brief talk about I740 drivers about a year ago
on the mailing list, but there appears to be no mention of I740 in the
source, so I'm guessing that nothing has come of this.
I'm trying to get my I740-based machine working in a sensible fashion. I
can't handle slow vertical refresh, nor white screens full of windows, so I
need a good fast text-mode. I'm using vesafb right now, but the best mode I
can get out of my BIOS is 640x480 @ 70Hz. Unfortunately this doesn't work
with the X I740 server, and anyway, I'd like more than 80x28.
I can see two ways forward - either write a fbdev driver, or a kgicon
driver. The kgicon approach seems to open up more possibilities, but I
don't know if this way is going to be easier or harder. I intend to copy
all the code that I can out of the X I740 server, which also includes
acceleration code, incidentally. I've looked over all this, and I'm
beginning to get a handle on it.
Given that I'm new to all these arenas (fbdev, kgicon, x-servers *and*
VGA-hacking), but that I'm willing to put some time in to get through these
obstacles, does anyone have any helpful advice or comments they could add.
Particularly, I reckon it would be easier for me to understand an existing
driver that is somehow similar to the I740, and pull everything together
that way. Any pointers to other sources of information would also be
appreciated.
Thanks in advance -
Jim
