I've had limited time to tinker, but it seems G5 support is not readly for primetime. My G5 is currently 2.0Ghz.

In Sysinfo:
E-UAE - 1.93 MIPS
E-UAE JIT - 2.65 MIPS
E-UAE.G5 - 17.27 MIPS
E-UAE.G5 SDL - 18.34 MIPS

E-UAE.G5 SDL is about 600% faster than current JIT on G5? Could that be right?

It's crashy as hell on my PowerBook but that is to be expected at this stage.

edit: Scratch that, I set cachesize=32768 and my regular OS3.9 installation booted straight to Workbench without falling over despite the docs saying OS3.9 doesn't work.

No Picasso96 UAEGFX screenmodes available though sadly so it's not quite as useful standard E-UAE.

On my PowerBook G4 1.67GHz

Sysinfo 4 with E-UAE_JITPPC gives 33 MIPS
Sysinfo 4 with Fab's E-UAE gives 15 MIPS

Running e-uae.g5 on this G4 gives 19 MIPS.

I checked again this UAE-JIT and discovered that the only way to load floppy images for me is to set "amiga.floppy_path=MyFloppyImagesPath". In fact, if I use the Ctrl+Alt+F1 nothing happens. I inserted SysInfo adf hen just to benchmark and.. wow...

Cook that RAM?!? I gues I can't cook an egg with this :P
Obviously, no way to load workbench from hard disk...
That black line in the bottom of the screen is garbage and I didn't managed to start UAE in window mode (tried "gfx_fullscreen_amiga=no | false | please | nope | f..k! XD!). Sometimes UAE stop running with an "JIT: Unexplained cache miss 0x2d10746c 0x2d10746c" error, sometimes it crashes.
And it still prompt this unknown config entry: 'enable_jit=true' message, though led is green/active.
@Intuition:
If I set "cachesize=32768" jit led stays black (=not active). ..???..

Will it be possible to emulate vanilla A1200 on G3 1GHz system *I count SAM460ex to be about that performance

For G5 there has to be a fix applied so the JIT will be working. Looks like it will be done soon:

Quote:

You're welcome. But I have more in the pocket: The next MorphOS release will come with Video Overlay possibility, to gain more speed on CybergraphX (Further MorphOS versions had this feature and I want it back!). Even we think about a patched version for G5 computers, which gains some more clocks on certain commands. You will get my sources when I'm done with merging the code (Fab's code).

I think the JIT is already working on G5, just that some instructions might not suit the G5 too well and are thus executed rather slowly. http://tenfourfox.blogspot.com/search/label/ppc970 has more information on general instructional differences between G5 and G3/G4.

Edit:

"“Mcrxr” is toxic on G5 cpu's, so I looked for it in EUAE, and there are few references too it, maybe this what causing slow down?"
http://www.amigans.net/modules/xforum/viewtopic.php?post_id=85905#forumpost85905

From Fab:
"sysinfo indicates about 85mips on a 2.3 GHz G5, which is rather ok (it's a private build that doesn't try to use the slow mcrxr instruction). [...] The released OS4 build is not "optimal" for G5 or PA6. It performs horribly when the mcrxr instruction is used."
http://amigaworld.net/modules/newbb/viewtopic.php?topic_id=29062&forum=27&start=160#726602

From Rachy (the JIT author):
"G5 needs a special version, which was compiled using a define. One of the PPC instructions is not availavle on G5, so it triggers an exception and it is handled by the OS."

Yes, the G5 patch is not only for JIT.
This Beta 1 doesn't have this G5 support at the moment. But we will include this in later releases (most likely Beta 2), so you can profit from more speed.
Also in Beta 2 there will be video overlay for MorphOS E-UAE.

For your Config problems:
The cachsize must be between 0 and 16384. Note that JIT only will be active, if set. 0 and not supported values will turn the JIT off, resulting in a black JIT LED field.
The switch "enable_jit" is not neccessary afaik as JIT will be activated when setting cachesize and a CPU which can use caches.
amiga.use_overlay will be used in the next Beta.

Funny thing is that the G5 problems were already mentioned: http://euaejit.blogspot.com/2012/10/jinxed-it-more-apples.html :)

Indeed, and the solution has already been worked out back then:

"Tobias Netzel [...] managed to fix up E-UAE for the G5 (PowerPC 970) processors. He got rid of the mcrxr emulated unsupported instruction [...] for this processor type. He also done some optimizations regarding the microcoded instruction usage [...]. [...] almost half of the emulated instructions make use of the mcrxr instruction for emulating some arithmetic flags. With the recent changes this PPC instruction is not used for anything if the emulator was compiled for G5 and the fix helps a lot on the interpretive emulation too."

To me as a non-developer, this sounds like it just has to be compiled for PPC970 target and the alternative G5-optimized code should be used automatically for the resulting binary.

Edit:

"Performance of UAE used to be bad on G5 CPUs. The reason for this is the use of the "mcrxr" instruction which CPUs of POWER4 and later POWER architecture versions don't implement at all. For that reason OSes like GNU/Linux or Mac OS X/Darwin catch the illegal instruction exception that is thrown when that instruction is being executed and emulate it in software. That results in a huge performance penalty. That "mcrxr" instruction is used explicitely in the optimized flags code. Turning off flags optimization when executing gencpu will restore performance on those CPUs. Additionally I contributed code to FS-UAE and E-UAE PowerPC JIT that works around that problem."

Yes, Andreas, this is what it should do. For this, there is a "define" to enable it. Unfortunately I don't have a G5 computer to test it, but now I found some ppl who will. So the Beta1 is strongly focused on the JIT implementation.
But don't worry, there will be a G5 version with JIT.

Now there:

"thanks to Fab the G5 executable is also available in the release package. [...] there were some murmur about the speed of the MorphOS version on G5 on some forums. No wonder: it needs a special version, which can be compiled from the sources for some time now. (Thanks to Tobias Netzel and to Fab for the special build.) Probably the same applies to the PA Semi processor"

I have tried, the 2nd beta on my 1.33ghz mac mini, but i have many sound interrupts when i want to play a game or a demo,
The first version from fab, whitout jit has not this problemes especially on games. For demos like from elude the jit version seems to be twice faster in framerate but the sound is desapointing

Update:

>> there will be a G5 version with JIT.

> Now there: [...]

The new beta doesn't come with a G5 built for MorphOS, unfortunately:

"as it seems there is no official compiler with G5 support yet in the MorphOS SDK and it is rather complicated and unreliable to compile any source for that processor. Until this situation is improved the G5 version for MorphOS won't be available from the beta binaries."
http://euaejit.blogspot.com/2014/05/ppcjitbeta03-switch-to-ludicrous-speed.html

"The compiling for G5 is still not resolved for MorphOS, no G5-optimized binary again, sorry guys. If you could tell me how can I (easily) compile the files for G5 on my iBook then I give it a go, I promise."
http://euaejit.blogspot.com/2014/07/ppcjitbeta04-fourfourfourfour.html

Fab?

Edit1: Fab did it
Edit2: added beta 4 quote
Edit3: Fab did it again
Edit4: And once more
