UAE JIT BETA 2

@LiveForIt

Yeah I just noticed that too. Don't forget to remove the parentheses I mentioned.

I don't know if cpu_24bit_addressing=false will cause an issue either.

Edit: I assume you're choosing "Boot Workbench" in RunInUAE? You need to make sure .uaerc_RunInUAE doesn't override any settings either.

@MickJT

Changing to 68020 did not fix anything.

done it 3 times already

I did have problems whit this demos before, the fix.
but I will try to change it to true.

Quote:

No I have not, I have created a new directory, and copied the .uaerc file into it, and made some changes to the .uaerc file.

I do not use RunInUAE for testing.

I have been testing with same settings on all beta versions.

@LiveForIt

I tried using your settings here. Clock shows up fine. It's probably something specific to the PA6T CPU that needs fixing.

I just meant to remove the line completely. I don't know what the default is.

That's good.

Alignment issue ?

@thread
I get these:
unknown config entry: 'sound_max_buff=8192'
unknown config entry: 'floppy0sound=0'
unknown config entry: 'floppy1sound=0'
unknown config entry: 'floppy2sound=0'
unknown config entry: 'floppy3sound=0'

Are those not used by UAE or mistyped or something else ?

@TSK

The floppyXsound lines will only be recognized by my builds that have driveclick sound support.

sound_max_buff was replaced with sound_latency in 0.8.29.

@MickJT

Yup! PegasosII G4 1266mhz and Radeon 9800 pro :P

"Calibrating timebase..." and "Timebase frequency:" if use_tbc is true,

Yes it is true :)

"EClock frequency:" if false

I will test and report it tomorrow just return at home and I'm really tired :(

An example of performance difference with and without JIT

@logicalheart
Speed about the same imho. Maybe some heavy demo can show differences (like something from latest TBL done for 060)

@kas1e

You can't really judge the speed of the JIT that way. If interpretive is 90% of real time in a demo, and JIT is 100% real time, that doesn't mean the JIT is only 11% faster, because the demo isn't going to play faster than its real time speed.

Benchmarking ADoom or something with the proper benchmark parameter would be better. Although tlosm gets colour issues with ADoom when the JIT is on.

@MickJT

Nope there are not color issue , all the Amiga doom versions when jit is active gave me corrupted graphic during the game all texateure map are broken (c2p?) without jit averything is smoth.

Better explain:
Menu of the game , splash image and music are perfect
Only during play everything is broken, only the 2d parts enemy and player hand/weapon are ok..
This problem is present in aga and rtg mode.

With beta 1 everything was ok but the game was running in ecs mode 32 colors.

The performance without jit is like play adoom with a 040 at 40 MHz .



I tested quake68k too (jit) it is working but after run the demo or some ware during play I have a guru meditation in the euae.


I will make more tests and report

@MickJT

I'm whit Kas1e on this logicalheart demonstration was a bad example. But you can't test it on 68060 when JIT only currently work whit 68020.

The thing is that JIT should not make DEMOS finish faster, that's just indication that timing is not working, its not a good thing if what you see is not in sync whit the music anymore.

It reminded me about poorly timed games in 1980 and 1990 on MSDOS.
http://www.sierrahelp.com/Utilities/SlowdownUtilities.html

back then some games used delay loops instead of propper timed delays.

A good way to test how fast JIT is to check (FPS) Frames Per Second on (FPS) First Person Shooter like games like Quake1 TimeDemo for example, or you can benchmark Lightwave rendering, or some thing like that, also fractals can be CPU heavy,

@LiveForIt

The Quake 68k clickboom version Crash in jit mode at beginning if i use 68020/68881 and after some second if i use 68040


edit:
Pegasos2 1266mhz Euae B2 in not jit mode
Cpu emulated 68040
320x240x8 Rtg
time demo demo2 = 2,20 fps 448,6 seconds

with 1 frame skipped

2.41 fps 408.7 seconds

@tlosm

Did not Nova Coder create a version of Duke Nuke'em, should be some way do time demo there also.

or at lest you can on DOOM.

@LiveForIt

the result is different compared the example you show.
(note the graphic is glitched)
Jit 040 rtg 320x256x8

total frames 1787
Adoom : 10399522 us 5919us/frame


Not jit rtg 320x256x8

total frames 2176
Adoom: 13156855 us 6046us/frame
