[B2-devel] SS MacOSX on PPC problem (precise timer patch issue?)

[Ronald P. R. <ron...@xs...>]

There is a problem with recent builds of SheepShaver MacOSX on PPC Macs.

SheepShaver launches normally and the virtual machine begins to  
startup normally. But then SheepShaver freezes at the MacOS welcome  
screen before extensions start loading. The same when trying to  
startup with extensions disabled. The message that extension are  
disabled appears in the welcome screen, but that is as far as it gets.  
SheepShaver does not react to anything anymore, it uses more than 90%  
of CPU time and the OSX side shows the spinning beachball. There are  
no unusual messages in Console.

The problem must have started with a change in August.

A 2009-07-14 build does not have the problem.

The 2009-07-26 build that Michael Schmitt posted here:
<http://www.emaculation.com/forum/viewtopic.php?p=30434#30434>
also does not have the problem. That build already contains the memory  
allocation error fix, although that fix was not yet committed to CVS  
then. If the fix was applied as it was used for this build, that  
excludes this fix as the cause of the problem.

A 2009-08-23 build and all later builds have the problem on PPC Macs.
Could the "precise timer" patch be the cause of the problem?

If I know which files are involved with that patch, I can try to build  
with earlier versions of those files.

Ronald.

Just wanted to drop you a line to thank you for the upgraded Sheepshaver. It
solved my previous problems -- and then some!

One other small glitch that I wanted to bring to your attention. I am unable
to paste directly between Internet Explorer and Clarisworks' spreadsheet. I
must first paste to Tex-Edit Pro, then copy again and then paste to
Clarisworks. It's a very small nuisance since I don't have to do this on a
regular basis, but you might want to look into the matter.

Those are the builds I compared. Your 2009-07-26 build does not have  
the problem, your 2009-08-23 build does have the problem.

There are now a couple of different reports from this (or at least a  
very similar) problem on PPC and one on Intel. SheepShaver either  
quits or freezes, always just after the MacOS welcome screen appears  
and before one can see extensions loading. Disabling extensions at  
startup does not help.

On my PowerBook G4 it is a freeze. The PB has a fresh and updated  
Leopard installation with no additional software but the Developer  
Tools.

You have seen the report of this (or a similar) problem an Intel  
machine in Emaculation.com forum.

Re: [B2-devel] SS MacOSX on PPC problem (precise timer patch issue?)

[Ronald P. R. <ron...@xs...>]

I compiled a new SheepShaver build that solves the problem on my  
PowerBook G4.
I posted it for others to try:
<http://www.emaculation.com/forum/viewtopic.php?p=31574#31574>

I built from CVS as it was today, with the exception of 5 files:

To undo the "precise timer" patch (added 17-10-2009 and modified  
21-10-2009) I used these files as they were in CVS on 16-08-2009:
BasiliskII/src/Unix/sysdeps.h
BasiliskII/src/Unix/timer_unix.cpp
SheepShaver/src/timer.cpp
SheepShaver/src/Unix/sysdeps.h

To undo the "sdl-audio" patch (added 19-02-2009) I used this file as  
it was in CVS on 18-02-2009:
BasiliskII/src/SDL/audio_sdl.cpp

I think the precise timer patch caused the crash or freeze at startup  
on some (mainly PPC) machines.

The sdl-audio patch appeared to cause degradation rather than  
improvement of audio performance. I already left it out of previous  
build.
