Yes. Now I deleted Cache/Kickstarts to let it rebuild.
This is what happens:

found file "cyberstormppc.rom"

Do I have the wrong one?

[FrodeSolheim]

That's normal. The CyberStorm "ROM" isn't registered in the ROM database (because it isn't really a ROM, it's a flash-able image which can change, and thus the checksum will change too).

Instead, FS-UAE will try to find cyberstormppc.rom (by exact name) in the Kickstarts directory when it want to load the ROM. Please attach the entire fs-uae.log.txt when failing to find cyberstormppc.rom without explicitly specifying the ROM file. Perhaps I can see something interesting in the log.

log attached

[FrodeSolheim]

OK, I found the problem (Not directly from your log, but since the log was perfectly fine, I started to look for a bug and found it ) -Will be fixed in the next dev version.

i succeed in compiling qemu-uae.so 64 bits, but now where to put it and how to declare it in fs-uae ?

Create this structure (copy or symlink qemu-uae.so):

FS-UAE/Plugins/qemu-uae-linux-x86-64
FS-UAE/Plugins/qemu-uae-linux-x86-64/plugin.ini
FS-UAE/Plugins/qemu-uae-linux-x86-64/1.0.0
FS-UAE/Plugins/qemu-uae-linux-x86-64/1.0.0/qemu-uae.so

Plugin.ini:

[plugin]
version = 1.0.0

[linux-x86-64]
libqemu-uae = qemu-uae.so

yeah perfect !!thx

Over 18000 MIPS ???? Possible ???

I would take any (synthetic) benchmark with a pinch of salt I imagine very good results will be achieved with CPU-heavy benchmarks (especially integer-based ones).

Real world performance when taking graphics, I/O (and floating point numbers) into account is probably less impressive than (some) benchmarks

People's subjective feel for the speed compared to real PPC boards is probably just as good a test - plus some timed tests can be useful (how long does it take to do X)

is there any "Good" PPC Benchmark Prog to use ?

Perhaps a better real-world-benchmark:
Get the PowerUP version of bzip2 http://pup.aminet.net/package/util/arc/bzip2 and compress/decompress a specific (big) file under emulated OS and host OS and measure the time it takes. A comparison against the PearPC implementation could be interesting as well.

So, if anyone is in the mood to do this, I'd love to see some numbers.

hard to measure time except with a stopwatch, which is not very accurate...

The Best would be to compress a file with a method/tool who give the real time compressed/uncompressed.

No, there are tools available for exact time measurement, even the "original" GNU time command is available for m68k.

cool thx

Well done, Frode. Since we can install OS4.1 in FS-UAE as well, perhaps you can provide a tutorial on "Installing AmigaOS 4.1 in FS-UAE", to complement the AmigaKit/ClassicWB tutorials.

[amigafreak68k]

I could do this if wanted

Done.

Apologies if this has been asked before, but I see on the FS-UAE homepage that it can be built for PowerPC Macs.

Is there any chance that the CyberStorm PPC functionality could use native code instead of being emulated to make maximum use of the host PowerPC cpu?

Thanks!

It is theoretically possible the QEMU plugin could use KVM on a PPC Linux host to run the PPC code on the real CPU (i.e. the plugin could be compiled with --enable-kvm).

There are probably be several potential complications. For example, there could be problems with bus and decrementer speed. And I'm not sure if QEMU can use KVM and still emulate CPU behavior Amiga expects (hide CPU differences, etc).

Finally, it's not something *I* will attempt anyway (lack of motivation plus lack of PPC hardware )).

So unless some PPC expert shows up and says it is possible, ... *and* volunteers to do the work and testing, the chances are slim...

[billt]

Now that there is Qemu plugin for PPC CPU, is there any chance we can also benefit from Qemu's VFIO pci-passthrough and coming platform-passthrough so that AmigaOS inside emulation can directly access actual hardware? I think this would make driver work a little more interesting for those interested in that, and gain some better capabilities from the host.

Or is there already soe way of this? (I could not find anything about this with a quick search yet)
