I have to try again, there was something else going wrong after I had exchanged these with decimals...

ok, had another go.
First I found that my "illegal instruction" crash I experienced last time was due to adding the wrong decimal value to one of the binaries.
But I'm not much further now 🙁
When I switch to dynamic core it just freezes. Eventually I just have to force kill it.
A non-debug build gives this information via gdb:

I have no debug build at hand because I don't have curses built. Another task for another day.

jmarsh, anything else you want me to do? add some printouts?

Things I changed so far in the code to make it compile:
- binaries to decimal in risc_ppc.h
- commented "#define USE_SDA_BASE" in risc_ppc.h (as per your instructions)
- changed config.h after ./configure with #define C_DYNREC 1

Good news from PowerMac G4 land; both the dynrec and drive sector-size patches are working well. The dynamic core lets DOSBox operate at roughly 4600 cycles before this machine's CPU maxes out and starts dropping audio chunks, where as the normal core only allows up to 2400 cycles.

Very nice work on this patch jmarsh!

This is on a PowerPC-7400 400Mhz machine running an up-to-date Ubuntu Linux. It was a pleasure to see DOS games running at fast 386 speeds, given this machine came out in 1999 when Microsoft still supported DOS 7.0! 🤣

Some notable system-configurations needed to get a usable and accelerated X display:

  • kernel boot arguments in /etc/yaboot.conf: video=aty128fb:800x600-15@60 offb=off (and optionally apparmor=off audit=off)
  • kernel module additions in /etc/modules: r128 and atyfb, which in turn pull in the northbridge (uninorth_agp) and direct rendering (drm) modules
  • The xorg stack needs to be switched to the more up-to-date hardware-enablement equivalents to detect the Rage128 AGP card (xserver-xorg-core-hwe-16.04, xserver-xorg-hwe-16.04, xserver-xorg-input-evdev-hwe-16.04, xserver-xorg-video-r128-hwe-16.04)

And the usual gang of linux details..

Were you able to build with "#define USE_SDA_BASE" left uncommented (active) in risc_ppc.h?

Yes, the only change I made was defining C_DYNREC 1 in config.h after ./configuring.
Left everything else as-is. Here's a copy and from risk_ppc.h:

// disable if your toolchain doesn't provide a _SDA_BASE_ symbol (r13 constant value)
#define USE_SDA_BASE

I need this patch for 10.3.9 PPC G4, but have no experiences on how to compile dosbox binary, but I have installed the development-tools.
Is there a simple howto for a newbee ?

Thx

https://www.dropbox.com/s/kvhujmw1crygmow/dos … vn.app.zip?dl=0 <- that's my build. Run it with output opengl. Remember to use the correct preference file. It might fail on a 10.3 system though. Some stuff needs 10.4 I think. Never tried below 10.4

Ich würde lieber nicht mit einem fremden Gerät rumhantieren und gerade bin ich ehrlich gesagt zu kaputt um eine Anleitung hervor zu zaubern. Aber 10.3 kann echt eine Hürde sein. Now back to English, please 😀

No problem for me, take that machine as a gift. A have several ones 😉
All I need is your adress and I will sent a ready to go package.
I don't think that I can do that by myself.

First I will test your app on my setup.

Is this build still available? This link 404s.

Failing that, I can reconstruct it on my G5, but I'm not sure which revision it was done against (though I guess the patch should still work against tip?).

Okay, I've reconstructed it against trunk. Nice work! I built it with gcc 4.0.1, the default with Xcode 2.5. It didn't like one of the inline asm blocks and using sys_icache_invalidate() in the commpage is probably better anyway (less likely to have side effects), so I tweaked risc_ppc.h with some __APPLE__ ifdefs. Otherwise it "just worked" without changes. Death Rally is now playable on the G5 without having to run the cores in Maximum Space Heater mode.

I think I'll see about porting this to ppc64le next. Much of it should work, though the ABI is a bit different.
