Re: C&T acceleration support, needs testers.

Hi, 
Thank you for responses.

From: Don Lunder <redacted>
Subject: Re: C&T acceleration support, needs testers.

I'll keep playing with it, and tell you what I find, if you have any 
specific requests, please do ask!

I'd like to further know,

- Difference between 8bp and 16bpp. 8bpp doesn't cause endiannes problem but
 may be more unstable.

- Vertical band problem, more precisely(ex. both 8 and 16bpp? happens
 at what X command? appearing location and size?, etc.)

- Difference between chipsfb and offb(BootX' "no video driver").
  When kernel booted with "no video driver", Xpmac with -ct6555 option
  does BitBLT origin offset calculation, color palette handling and aperture
  setting. I have report that reading color palette immediately causes
  machine check exception resulting in kernel panic(why??). And if aperture
  setting is failed, Xpmac goes into infinite loop.

PS After Spell checking the email, I see that register has a typo in the 
Xpmac out put. <shrug>

Oops! :-)

Anyway, I'll soon upload the source code(at the same place, please check)
so that anyone can try and fix it, before I'm on a vacation.

In the mean time, I had a advice that I should end it and spend time
for new XFree(4.0). I'd be glad if someone continued to work on this,
though I haven't decided anything yet.

Yes, working on XFree86 4.0 (3.9.15 these days) will benefit all platforms.
