Bug#512273: xorg: Macintosh BlueWhite G3 w/ ATI 3D Rage Pro - monitor complains out of range

2009-01-19 Thread Rick Thomas 

Package: xorg
Version: 1:7.3+18
Severity: important


I recently installed Lenny on a Mac BlueWhite with an ATI 3D Rage  
Pro video card.


When X starts up the monitor displays a message out of range  
indicating that the
computer is feeding it stuff it can't handle.  (This message is  
coming from the
monitor, itself -- not the X software).  The image on the monitor  
shimmers and

jumps and looks like snow in a high wind.

I've tried several tweeks to the xorg.conf that have worked on other  
machines
with similar problems.  None of them seem to help.  I'm attaching the  
most

recent non-working xorg.conf.  I'm also attaching the Xorg.0.log.

lspci -v says this about the video card:

01:02.0 VGA compatible controller: ATI Technologies Inc 3D Rage Pro  
(rev 5c) (prog-if 00 [VGA controller])

Subsystem: ATI Technologies Inc Device 
Flags: bus master, stepping, medium devsel, latency 16, IRQ 23
Memory at 8100 (32-bit, prefetchable) [size=16M]
I/O ports at 1400 [disabled] [size=256]
Memory at 80881000 (32-bit, non-prefetchable) [size=4K]
Expansion ROM at 8000 [disabled] [size=128K]


Any suggestoions?

Bug#512273: xorg: Macintosh BlueWhite G3 w/ ATI 3D Rage Pro - monitor complains out of range

2009-01-19 Thread Risto Suominen 
2009/1/19 Rick Thomas rbthoma...@pobox.com:

 When X starts up the monitor displays a message out of range indicating

 the
 monitor, itself -- not the X software).  The image on the monitor shimmers
 and

This sounds worse than my problem, but it may depend on the same
source, i.e. something probably programmed in by Open Firmware into
the chip's registers.

Looking at file atidsp.c, function ATIDSPPreInit, near its beginning,
you can see:

/* Retrieve XCLK settings */
IOValue = ATIMach64GetPLLReg(PLL_XCLK_CNTL);
pATI-XCLKPostDivider = GetBits(IOValue, PLL_XCLK_SRC_SEL);
pATI-XCLKReferenceDivider = 1;

What I did, I changed the line setting pATI-XCLKPostDivider to:

pATI-XCLKPostDivider = 1;

and the problem with my display image disappeared.

Now, I can't say that 1 will be the correct value in your case, or
even promise that it won't make things worse. And I must add that I
made my change in similar code in Linux kernel's
drivers/video/aty/mach64_ct.c on an Oldworld Mac.

The result from this change will be that some values calculated by the
code and later written into the chip's registers become different.

I found some useful tools for peeking and poking the chip, f.ex.
atydump, I will put a copy available here:
