Testers with Rage 128 needed

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello,

I just committed a preliminary console driver for ATI Rage
128  
graphics controllers - many G4 PowerMacs shipped with those.
The  
driver uses the blitter for scrolling and rectangle fills
which  
already gives a nice speedup over genfb or ofb.
There's one problem though - the driver matches exactly one
card but  
there are about 30 variants in the wild. So, if you have a
Mac with a  
Rage 128 graphics board please:
- - build a kernel with r128fb at pci ( tomorrow's GENERIC
should have  
it )
- - see if it attaches to your board. If it does please
report success  
or failure. Otherwise either change r128fb's match function 

( r128fb_match() in sys/dev/pci/r128fb.c ) to your card's
PCI ID or  
mail me your card's pcictl dump output and I'll build a
kernel.
I don't have any real documentation, what I know about these
chips I  
got from reading xfree86's driver source so I don't know
which cards  
will work and which may need what kind of special handling.
The  
driver also makes no attempt to program any flat panel
registers - we  
may need that on at least a few powerbooks and some G3
iBooks.
The blitter should be the same on all variants so the driver
as it is  
now should work once it matches the right PCI IDs.

have fun
Michael

This is really nice, thank you!
We have a PowerMac G4 "AGP graphics" with Rage 128
Pro graphics. I
can't have access to it until this weekend, though :-( .
So this weekend I'll test the driver and report any success
or failure.

Accelerated console is a great improvement over the slow
ofb(4) (even
with the cache hack). Although the new genfb(4) supporting
shadow
framebuffers is much faster than any ofb with or without
hack.

Cheers
Marco

would a PCI or AGP Rage 128 card help you?

Anything other than this:
r128fb0 at pci0 dev 16 function 0: ATI Technologies Rage
Fury MAXX  
AGP 4x (TMDS)
r128fb0: 64 MB aperture at 0x94000000
wsdisplay0 at r128fb0 kbdmux 1: console (default, vt100
emulation)

with Apple or Sun firmware would be useful. PCI or AGP
doesn't make a  
difference - the above card is in fact AGP.

have fun
Michael

Do you have a kernel image with the driver to test?  I tried
to get
the latest releng snapshots from yesterday but they don't
seem to be
available in the FTP server (although they are mentioned in
releng.netbsd.org); perhaps due to the server relocation
that was
announced yesterday.

(I'm running the 4.0 branch right now...)
