I've dropped that patch.

Thanks!

ATI Rage XL

[cp]

hi
in the PA wiki (1) the ATI Rage XL (mach64) is reported to have
worked. In combination with the fbdev X-server from XFree86/X.org

I think the news was related to kernel 2.6 or something very old.

Can anyone confirm it's still working with kernel 5.*?

I don't happen to have a card to test myself. Not yet.

Re: ATI Rage XL

[cp]

Apple PowerBook-G3 use these cards

Name       , Model , GPU             , driver , vram ;
wallstreet , M4753 , ATI Rage LT     , mach64 ,  2MB ;
lombard    , M5343 , ATI Rage Pro LT , mach64 ,  8MB ;
pismo      , M5343 , ATI Rage 128    , ati128 ,  8MB ;

So maybe there is still some interest in supporting their kernel drivers.
Sooner or later I will try to grab some of these PCI cards and try
them with HPPA on modern 5 kernels. *

I know there is also a miniPCI version of the ATI RageXL and it's used
with some IBM servers, so again, maybe there is still some interest
even from those guys ...
