[PATCH] tdfx ported to new fbdev api

[James Simmons]

As you can see I have ported the 3dfx fbdev driver to the new api. It has
been tested on my home system and it works. I like others to try it out.
The patch is against 2.5.5-dj2

Thank you.

 Is this one different to the one I saw last time?

Their are a few changes. I tested it last night and it worked for me. That
doesn't mean much so if you could give it a try. BTW the penguin will not
show up. I need to expand the imageblit function but it is not top
priority right now.

 Now that you mention the penguin, I was reminded of something.
 Normally with this box, when the fb starts, the top 3rd of the
 screen has a large white rectangle blitted onto it for reasons
 I never figured out. Its purely cosmetic (it disappears when scrolling
 begins), so it wasn't something I really bothered investigating.

 It could be that with your reworking, this bug has taken on
 a new form, and is now doing something more dramatic.

   Attila Kesmarki's v0.2.0 patch for tdfxfb fixed this problem for me
when I tested it about a year and a half ago, but I don't think his
updates were ever integrated -- I don't know if there were issues with
the changes or not.

   Anyway, the patches still seem to be up:

Actually no. I think the driver hasn't changed. I does work for me. Did
you try it out again.

 Ok. I didn't look too deeply last time, but it died immediately
 on switching the display, and was really dead, no keyboard leds,
 nada.

 I'll take another look later if I get chance

That was my experience also (Voodoo 4500 pci/Alpha architecture).
However, the VIDCFG_2X handling in his patch worked, and the kernel
(pre-2.4.18) didn't. Luckily, a small patch was accepted to change that.

I'm willing to test any patches for tdfxfb on Alpha.

Good luck,
Jurriaan
