[Cin] qemu-system-ppc (was: Re: cinelerra-gg on ppc64el )

[Andrew Randrianasulu]

I know emulator can have their own set of bugs, yet for those without ppc 
hardware qemu can emulate something:

http://forum.hyperion-entertainment.com:80/viewtopic.php?f=58&t=4007&start=60

from this forum:
qemu-system-ppc64 -M ppce500 -cpu e5500 -m 
2048 -kernel /home/christian/Downloads/uImage-4.17-without_corenet -drive 
file=/home/christian/Dokumente/ubuntu_MATE_16.04.3_LTS_PowerPC_QEMU/ubuntu_MATE_16.04_PowerPC.img,index=0,if=virtio -net 
nic,vlan=0,model=e1000 -net user,vlan=0 -append "rw root=/dev/vda3" -device 
virtio-vga -device virtio-mouse-pci -device virtio-keyboard-pci

my comment - mttcg (smp acceleration) require host bitness == guest bitness, so, 
use 64-bit build of qemu.

I presonally only tried qemu-system-ppc on 32-bit host.

with http://www.xenosoft.de/vmlinux-4.17-AmigaOne_X1000_X5000.tar.gz

I tried 

 qemu-system-ppc64 -M ppce500 -cpu e5500 -m 2040 -smp 
8  -kernel /dev/shm/vmlinux-4.17-AmigaOne_X1000_X5000/QEMU_e5500/uImage-4.17 -display 
sdl,gl=on - and with sdl video output it showed qemu's internal monitor and 
serial output from virtual board - try to ctrl-alt-1 / ctrl-alt-2 for switching 
between outputs .... Note , sdl windows can be stacked one over another, so try 
to move them via window title.

this specific kernel apparently configured for 4 cpu machine, but you can try to 
compile it differently.... (for bigger numbers of cpus).

qemu-system-ppc64 -M ppce500 -cpu e5500 -m 2040 -smp 
4  -kernel /dev/shm/vmlinux-4.17-AmigaOne_X1000_X5000/QEMU_e5500/uImage-4.17 -nographic 

started to output directly to X console, and I again forgot how to quite it 
properly from this mode :/ [*]

Ctrl-A , C ... it seems

Note, this is BE (big endian) machine, and e5500  doesn't support altivec. -cpu 
g4 will give you altivec, yet emulated Mac machines (-M mac99, -M g3beige for 
qemu-system-ppc) are single-processor only, so compiling stuff (esp. like 
Cinelerra) will take a lot of time ..
