I have a feeling the screamer will also go into main code sometime in the near future ;-)

Re: GSOC qemu Boot Mac OS >= 8.5 on PowerPC system

Also, it's possible that this has to do with the PMU (lack of) emulation -- if you disable all energy saver settings and screen savers, does it still freeze? Haven't thought about that. I will try this and report back. It worked! Going into the energy saver pane in System Preferences and sliding bo...

Re: GSOC qemu Boot Mac OS >= 8.5 on PowerPC system

I have to admit I haven't run the latest builds for more than about 5 minutes... do you have a dumpfile from your host OS? Or is the freeze only in the guest OS and qemu's still happily running? QEMU was still running. I went into the monitor and used the 'info registers' command to see if the CPU ...

Re: GSOC qemu Boot Mac OS >= 8.5 on PowerPC system

Lately I have been noticing my Mac OS 10.4 VM freezing after only 10 minutes of use. Has anyone else noticed any freezing issues?

Re: GSOC qemu Boot Mac OS >= 8.5 on PowerPC system

I'm going to guess when you push the run button QEMU might appear for a second then disappear. I would go to File->Display Full Command-Line and paste this text into a terminal window. Then try to run it. If QEMU outputs an error message you will be able to see what is wrong. Usually it is trying t...

Re: GSOC qemu Boot Mac OS >= 8.5 on PowerPC system

Hi, It seems the beta 2 runs in Sierra, where I had problems before. Can you add a build that supports resolution switching? It is available in the default source. Or add an option to select a resolution that goes into the -g argument? Version 2.10 is what will be bundled and it supports resolution...

Re: GSOC qemu Boot Mac OS >= 8.5 on PowerPC system

Thank you very much everyone for the help. I plan on making guest sharing a lot easier with my front-end application. Hopefully it will be as easy as simply selecting a folder to share. For those who are not familiar with my front-end, the link is here: http://www.mediafire.com/file/7parvyzvdabpe74/...

Re: GSOC qemu Boot Mac OS >= 8.5 on PowerPC system

Has anyone been able to make sharing work on Mac OS X? I wanted to open up an Appleworks file on my host system in the guest. Working with one set of files would make things easier than having to copy between guest and host. I have tried AFP, FTP, and SMB. All of them failed with my Mac OS 10.4 guest.

Re: GSOC qemu Boot Mac OS >= 8.5 on PowerPC system

Just wanted to report my research. Since Rosetta fails more floating point tests than QEMU I thought it would be interesting to see what happens when the PowerPC version of Quicktime is ran in Rosetta. I was actually hoping for poor audio playback. What actually happened was MP3 audio played back pe...

Re: GSOC qemu Boot Mac OS >= 8.5 on PowerPC system

Floating-point math is probably the most tricky part of CPU/FPU emulation. I have spent lots of time improving 68k FPU emulation to a point where one expect to get "99% correct results" recently. I don't know how QEMU emulates floats (native or software floating point library?). Using any...

I made a program that tests various floating point instructions. Just double clicking on the "fpscr test" program is all it takes to make it work. The program indicated that most of the floating point instructions in qemu-system-ppc are not correctly implemented. If you want to try testing...

Re: GSOC qemu Boot Mac OS >= 8.5 on PowerPC system

Good work, Qemu's PPC emulation is about 1/2 to 1/3 of SS on my system and Altivec is about 1/10 of SS, and SS is nowhere near the performance of Apple's Rosetta. Sheepshaver sound like the superior technology. I think it has a two stage translation system: PPC -> x86. QEMU has a three stage system...

Alternatively, if you have access to Ida, it will happily detect PPC assembly and output it in readable form. I believe there are demo versions of Ida for Mac available as well from the Ida website. I couldn't find a free demo of IDA that would disassemble PowerPC code. If you find it, please share...

I was talking to the Openbios maintainer about VGA resolutions. His idea is to only supply a couple of built-in resolutions and one resolution the user specifies with the -g option. I think he wants these built-in resolutions only: 640x480, 800x600, 1024x768 1280x800 1440x900 1920×1080. My idea was ...

Ah; I moved from Tk to WxWidgets in the late '90s.

As soon as OS X came out, WxWidgets was ported, which *should* have spelled the ...

Works nicely now. Here are my first impressions. I think it is a bit slow in showing the Qemu window. I sometimes think it has not started. There seems no feedback when things do go wrong in e.g., the additional arguments. And there is no way of knowing you best use e.g., -M mac99 to boot the curre...
