Hi, I tested both OpenBIOS and Qemu from your branches in OSX, using mac model mac99p. Terminal says:
MACIO: Creating PMU qemu-system-ppc-wip: Unknown device 'via-pmu' for default sysbus
Check you updated the qemu config. I added a new device, you need CONFIG_MAC_PMU, the qemu build system won't pick that up automatically.
I don't remember how I did it, I think make defconfig or something like that..
Cheers, Ben.
Great to see Leopard running. Nice work!
I fixed the error by adding CONFIG_MAC_PMU=y to the default config for ppc-softmmu.mak Builds from your source fix the USB problem in OpenBIOS mainline needing the -device ich9-usb-uhci1,id=newusb -device usb-mouse,bus=newusb.0 to get mouse/kb going in 10.5. Leopard now has mouse/keyboard working without any specific USB parameters.
I notice the problem in Puma (10.1) It seems there is some timer error?, as e.g., the time remaining for installation fluctuates like crazy (1600 hrs to go), and the beachball spins like mad. At boot there is a too rapid succession of “still waiting for boot device” . Just guessing, but might a timing issue also explain the slowness of Leopard?
Best, Howard

Possible. I'm not really sure, I haven't had too much of a chance to investigate but it's quite possible that there's a problem with time base calibration.
Though the VIA part of the PMU is identical to the CUDA part (unless I missed something up ...)
Cheers, Ben.

Regarding Leopard, I think that it's just slow :-) I installed it on my old Mini G5 and it's definitely much slower than Tiger accross the board.
Chers, Ben.

What is a Mini G5?

A typo :-)
Mini G4, ie, PowerMac10,1

Ok.
Just curious, if you have noticed how poorly audio plays in Mac OS 9 and 10 guests, would you know why?
