I will do a port for the X1000 in a couple of hours.

Edit: Email sent to the usual people :)

Sadly my Amiga is boxed right now or else I would be stress testing this too.

Really awesome effort to get this out of the door! Even more impressive is the speed at which it is developing.

Did I read that the PA6T is not fully supported by it yet?

Almos and I don't really know. I'm just building it against a G5 target (-mcpu=970) and also with -mno-powerpc64 (otherwise the mouse movements are inverted). If the PA6T has other missing instructions (other than mcrxr) that get emulated by the OS, then it could be sped up further. Tobias Netzel wrote an mcrxr replacement function for G5 CPUs.

Thanks. Does the PA6T make use of the mcrxr replacement function for G5 CPUs?

That's not the right way of wording it. G5 and PA6T don't have an mcrxr function. From what I've read, the operating system traps and emulates that function.

http://tenfourfox.blogspot.com.au/201 ... s-your-javascript-no.html

Going by that last link, it's the trapping that slows it right down. Avoiding the use of that function altogether is much faster.

So for E-UAE, Tobias wrote a replacement function that does the work of what mcrxr would do, using other CPU instructions instead. That way, E-UAE never even tries using mcrxr when _ARCH_PWR4 is defined at build time (which gets included when you use -mcpu=970).

tommysammy notified me about some problems with the X1000 builds I did. Anyone who got an e-mail before will receive another one very soon.

Edit: Emails sent. It's related to the issue I had with ffmpeg. I think it's the binutils I have causing an issue at the linking stage if certain flags are used (altivec). Altivec flags aren't needed to build e-uae but I used them as an experiment.

Edit 2: Probably not binutils but libgcc.a?

There's an "official" X1000 build now: http://euaejit.blogspot.com.au/2014/0 ... dreds-and-xthousands.html

It lacks uaescsi.device, but I've let him know about that.

Thanks a lot all involved ! For example TBL Starstruck demo plays perfectly on X1000. So JIT really makes difference when UAE is compiled properly to different CPU's.

Got Starstruck and Rift from TBL working.
It is very fast

Just a quick test as I don't use UAE a lot.

I have 2 setup WB31 and WB39.
With standard UAE and X1000 one, I use the same UAE.rc config

With standard UAE
WB31 & WB39 are windowed and nice colors/resolution (UAEGFX 1024x768 32bits), full-screen works fine.

With standard UAE
WB31 & WB39 are full-screen with white big borders and bad colors/resolution (PAL Low resolution), no way to switch fullscreen/windowed with CTRL-ALT-S keys


Have the rc files have to be modified with this new version ?

Thank you

Forgot to say I PM'ed you yesterday (if you didn't notice already). How did you get Rift working ? It gets stuck when black dressed woman is displayed on my machine.

You have to add few settings which are needed to enable JIT. Check the readme. I haven't found a perfect config yet.

thank you, I had read the ReadMe, especially that :

"You can reuse the same configuration files, HD image files, prepared folders that were already working with the previous E-UAE version."

Now, I will try that :

However, for testing the JIT implementation please make sure you set up the configuration exactly as listed below:
cpu_speed=max
cpu_type=68020 (or 68EC020, 68040, see Known issues)
cpu_compatible=false
cpu_cycle_exact=false
blitter_cycle_exact=false
comp_optimize=true
cachesize=8192 (or higher)
comp_constjump=yes
comp_trustbyte=indirect (see Known issues)
comp_trustword=indirect
comp_trustlong=indirect

Are you using an SDL build at all? lalt+lctrl will change to F12 unless you add sdl.map_raw_keys=true into .uaerc
