WinUAE 3.0.0 beta series (was 2.8.2/2.9.0)

Separate thread for PPC stuff would be nice but it should be started by someone who actually knows about PPC and wants to help

Install CGX update from Aminet. Older version seems to assume some specific interrupt state after VGA chip has been reset/woken up. Can't fix it because I only have PicassoII which does not support interrupts.

I'd say this is non-problem. PPC CPU emulation will try to stay idle (thread sleeping) longer than real CPU to not cause extra host CPU activity because PPC CPU code (when idle) has habit of sleeping a bit, then checking something, sleeping again and that is practically same as staying mostly active all the time in emulation.

It is really amazing how quickly you were able to do this.

It was much simpler than I thought it is. Board is quite simple, only few registers, most of the time was needed to find out how registers actually worked (it was only partially documented in netbsd and linux but it was great help), PPC CPU was quite easy part, only needed to check PPC specs that PPC CPU initial PC is 0xfff00100 (or 0x0100) and the rest was simple glue code.

I have strange black screen after my workbench loads. Happens after I installed the WarpUp libraries off the OS3.9 CD. Before that it booted ok. After I had installed the WarpUp libraries I got a major crash on WinUAE. I have attached the crash dump file and config. I've read the whole thread so thought I was following things correctly. I've renamed my rom to cyberstormppc, JIT is turned off etc. I have a quad core Intel i7 3770k at 3.5Ghz so my hardware isn't the problem.

What is today goal in WinUAE ? A perfect Amiga PPC emulation ? Or is still a perfect Amiga 500 emulation ? (hopefully both)

p.s. In a case of A500, FYI, there are some new issues reported in the "Problematic Demos" thread waiting confirmation!


EDIT: Also, what happened with better A1200 CE emulation ?

(It was either better 68020 CE emulation or CD32 FMV. FMV win because it is totally different and I got bored with all the recent CPU stuff)

Seems everything gets priority over better 68020 CE emulation! (even so unwanted PPC and never mentioned accelerators)
(p.s. Got bored with the recent CPU stuff !? ... but didnt PPC emulation is also a CPU stuff ?)

A500+ 4MB quickstart with low compatibility freezes immediately.

After start it opens a log window with this contents:

  D0 00000000   D1 00000000   D2 00000000   D3 00000000
  D4 00000000   D5 00000000   D6 00000000   D7 00000000
  A0 00000000   A1 00000000   A2 00000000   A3 00000000
  A4 00000000   A5 00000000   A6 00000000   A7 00000000
USP  00000000 ISP  00000000
T=00 S=1 M=0 X=0 N=0 Z=0 V=0 C=0 IMASK=7 STP=0
01000FFE 204a                     MOVEA.L A2,A0

Then it just sits there with the Windows busy pointer.

Stop asking this all the time. I do what I want to do. Plans will always change.

Current is PPC and when it is finished (it already works good enough for me), then it is back to normal stuff. It should have been obvious. (PPC also got higher priority than normal because of donations! Thanks again.)

Crash is in NCR53C770 SCSI code but you don't even have anything mounted to CSPPC SCSI. EDIT: Is this repeatable?

Log needed to analyze black screen.

Fixed. (Not related to Fast RAM, 68000 without CE and more compatible used wrong memory access functions)

Maybe it was a one off. I only had a short time testing this out this morning. It only crashed like this once. I tried enabling logging but haven't seen any files created. Is it saved in documents and settings as I was expecting it to appear my WinUAE folder. I have a feeling it could be Picasso IV/Zorro III related as the Workbench loads but quickly turns the screen black.

Enable it in Paths panel (before starting emulation) and when you want to open the log, click "Save all" button. It opens text file that contains everything (config, logs).

It can, sometimes, but note that it still won't make me to learn PPC assembly and everything. Only the basics.

Or to disassemble and debug any closed-source PPC operating systems. That is Someone Else's Problem.

PPC emulation work like a charm.
The only thing that is missing is JIT.
You did a wonderful job Toni.

This is in contradiction ... if it already works like a charm how then JIT is missing !? (And also, how a wonderful job is done if JIT is missing ?)

Note: This always works in arcade games: "Please Insert Coin(s) To Continue"


EDIT: Welcome to EAB! (and sorry for being a smart ass on your 1st post, didnt noticed, just cant agree that a wonderful job is done yet, thats all)

Be not a smart ass, it was his first posting.

Because with JIT it will work faster, as simple is that.

Tony: Thanks for all your effort. I don't use WinUAE at all but will do with PPC emulation, few euros already sent via PayPal

Yeah, seems there are lot of smart asses here today ?

Note: Miss. AnnAWu, I didnt want to smart ass to nobody! (but if this bother you, your problem)

p.s. I just cant agree that a wonderful job is done if JIT is missing! (thats all)

It crashed again. The logs seem to be saying I am getting SCSI errors??

[fitzsteve]

The backup I took of my old A4000T (CSPPC/PicassoIV) works a treat with PPC emulation, WarpOS 5.1 & WarpDT is installed IIRC.

The nearest I get to anything WOS running is Grey screen on ADoomWOD but no crash!

Other Games just Crash out, great work so far - waiting for the next update's

You need to use -bus 40000000 for AdoomWOS or AdoomPPC, otherwise software just detects a bus speed of 0 at the present time.

It went wrong earlier:

May not have anything to do with emulation. Can't really help unless it can be duplicate easily. But if there are any unofficial patches: unsupported unless it is confirmed they really do work with PPC boards.

Great but few posts ago I said nothing will change unless there are proper reports and also some easy way to duplicate it. (=zip I can unpack somewhere)
