@AmigaBlitter

Thanks for posting the link. I wonder what improvements could be made regarding the reference to an executable compiled specifically for PA-Semi / X1000

@logicalheart

Its almost as slow as interpreted emulation on X1000.
The opcodes in the Just In Time compiler are not compatible whit Pa-Semi.

AmigaOS4 emulates missing opcodes, and result is slow run time speed.

This are Dystone numbers I have from SysInfo:

EUAE Beta 1: 4880
EUAE Beta 2: 4918
Old EUAE before JIT: 3540.

Yes there are some improvement but not major like you see on G4.

The EUAE-JIT G5 version is only availabile on MorphOS/MacOS, so I can't test that one.

On my SAM460ex if I don't set 'ppc.use_tbc=false' in .uaerc timebase is wrong calculated:
..
E-UAE 0.8.29-PPCJITBETA02

Opening cfgfile '.uaerc'...okay.

Setting such option I get:

"executable compiled specifically for PA-Semi / X1000"

Do we have gcc that supports compiler optimizations for PA6T?
Then... we need gcc that is aware of e5500 & e6500.

Am I right in thinking that the GCC we have pre-dates the PA6t? I'm not sure anyone is maintaining GCC are they? We really need support for our flagship.... is the current GCC version in thr official GCC repisitory?

Well done on the JIT progress though!

E-UAE JIT beta 2 detects sam440ep and skips calculating the timebase. MACHINETYPE_SAM460 isn't included in the SDK that Rachy built it with, but I think that can be worked around without updating the SDK, seeing as it's just a numerical value. I'll let him know.

Here is the result:

Removed comment... strange I did not notice that, guess I copied the .uaerc file from some where.

Removing the comment made no difference.

Setting the CPU to 68020 and I get 4674

Setting ppc.uae_tbc=true.

Enabled the calibration.
and now SysInfo says I have 700 Mhz, before it was 7Mhz.

Dystones goes up to 4765.

Changing the CPU back to what it was 68EC020/68881.

Gave me 4857 Dystones.

The EClock frequency stays the same 66.666666 Mhz.

Yes is strange thing about TimeBase frequence I don't know if this is calculated or if this what it reads from Timer.Device :-/

As for slow JIT preperformance, I think thats because of what I wrote before, but maybe there is some thing strange going on, whit Timer.device.

I'm not so shore anymore, should it not be 1800 Mhz on X1000? Or what is the correct value?

Yes the Picasso96 video modes will be faster then AGA modes, 1 to 1 emulation, instead of having to do planar to chunky concertion + cooper emulation on the palette while converting it into native videomode, or what ever it does.

I'm shore the AGA emulation is efficient, but not as efficient as native video modes.

@LiveForIt

Do you get the same frequency issue (66mhz) with beta 1, or with any other version of e-uae, when ppc.use_tbc is false? Is the frequency calculated correctly if you use the non-JIT versions of e-uae and ppc.use_tbc=true ? Try with the version that comes with RunInUAE.

I know that on my sam440ep-flex, in versions of e-uae PPC JIT prior to beta 2 (beta 2 specifically detects a sam440 or amigaone, but not 460/x1000), if I didn't have ppc.use_tbc=false, the frequency would be calculated wrong and the JIT would be much slower. In my experience it definitely affects the JIT speed.

Looks like a define will need to be made for X1000, but someone else will have to figure out what to do for that. You could probably hardcode a figure that assumes all X1000 CPUs are the same speed (which afaik is true for now).

I have sent you a couple of private messages.
