Thanks. OGR-NG score is comparable to G3 1.5 GHz.

My cheap laptop gives G3 266 MHz performance in WinUAE/OS4.

dnet on g5 is near 35.000.000 keys


Don´t compare AltiVec value, only scalar is (more or less) comparable.

Don´t trust blindly such info. That is why I use simple CPU benchmark like dnetc.

yes but ... kvm usually gave the true speed in virtualizzation. I hope they will fix this timebase error for have the true cpu power like i have on MOL.

Don´t hold your breath too high. Only CLGD5446 4 MB is supported by OS4 (but driver is not included on SAM460 CD) and QEMU branch of this graphics chip is uncomplete (as far as I know they refused improvements Toni Willen did for WinUAE).

It's a bug in the ub2lb code. It does indeed send a NULL which clealry violates that API function. Took me a month to find it! When I was porting the code to AmigaOne. Wish I had that QEMU back then with sources when I was debugging it. All I had was a UBoot crashlog over serial and laying printf()'s in the code till it turned up.


I wouldn't like to be mean, but since ub2lb is GPL-v3 I assume that we (Giuseppe who was continuing my work on that code and myself, who initially started the u2blb project further renamed to parthenope) can hope for a commit some day?

The project is still on GitHub: https://github.com/cjg/ub2lb/

Neat.
Why not?
At least its not on X64.

Single thread virtualization could allow us to run multiple NG OS' copies on one system.
I like it.

Or, better yet, give me one process dedicated to that and another dedicated to SMP.

Are you building these binaries yourself or using prebuilt binaries? I'd like to try this on a mac mini g4 with KVM.

@themamboman

you need to clone the git from the github of qemu and apply all the patch one by one. i dont try the patched because for now for sure it not boot amigaos and morphos ... but Zoltan is working for made the two run.

Guess Zoltan is easy to remember. But do you mean I need YAFA? Yet Another Forum Account.

BTW. Have you tried TenFourFox? Don't know if Leopard-Webkit work on Tiger. Doesn't sound like it.

Apparently this line of code was added on purpose, svn revision 60, quoting the author:


Thanks for the info.

I'm more than sure that Giuseppe, who did that commit, knew exactly what he was doing.


The source I have up to 2010 has it. Putting in a kludge to break it on XE machines.

Quote:
Maybe new UBoot just silently ignores DSI... Dunno...


That would be a strange thing to do. And risky. I thought my XE UBoot accept writes to zero when it said it diskboot an image to zero. So I tried specifying zero as load location and it crash instantly. LOL.

Sure. It's wasn't my intention to be mean but I looked up the start_unit_scan() API function and I saw nothing about NULL being accepted for a scan_list. So I marked that as a bug. And was reminded of it this thread. I just disabled the NULL line in the code, a simple fix, that took me ages to find.

Perhaps Giuseppe can explains how he got that to work.
