cries /half-joking
The main reason for supporting PPC would be that it might be fun. And I do see the point about arm32 being pretty weak as a desktop platform. However I do remember that the arm32 port at some point managed to boot to app_server (where it then crashed). I might try to look at what
caused that regression when I find time.
The latest build on download.haiku-os.org works (hrev59669)! For me, running it with
qemu-system-arm64 -m 512M -bios /path/to/the/arm64/QEMU_EFI.fd -device ramfb -M virt --cpu cortex-a76 -device usb-ehci -device usb-kbd -device usb-tablet -device usb-storage,drive=dska -drive id=dska,file=haiku-arm64-mmc.image,if=none
worked (for whatever reason, qemu uses some cpu that is incompatible with the efi implementation they ship, at least on debian. I just used usb for everything, as it’s used for keyboard and tablet (you could use a mouse aswell, but a tablet device saves you from requireing a mouse capture). ramfb is rather failsafe on arm64. On debian the path of the tianocore binary is /usr/share/qemu-efi-aarch64/QEMU_EFI.fd if you install the necessary package. On other systems it should be quite easy to find an efi image online or you could extract it from the debian package.
Everyone who got this ported, this is some awesome work! (And perhaps a reason why I should finally get myself a raspberry pi 3 or newer (or some other arm64 sbc) xD)
