Hi,
In a wave of projects, over the years, I've been working on trying to rescue the Pistachio GitHub repository from bitrot, and build it with modern tools (I have one project that builds, and runs on x86, with an ancient version of GRUB, and another, that's a complete basket case, since KickStart is broken, but that's another matter), and saw, with some interest, ports to various Open Firmware-enabled platforms, and wondered if anyone had any guides to building, and running a PowerPC 64-bit userland, and boot infrastructure?
There was an old guide to building with PSIM, and PPC32, on the KIT Website, but it seems incomplete, and it doesn't seem obvious, as to how one would build a bootable disk image, or how to prepare the compiled userland to run on hardware.
Since the site is pretty dated, and the code has changed, since then, is that information even relevant?
I've got access to a FreeBSD 12 PPC64 build environment, under QEMU's PSeries Xenial machine emulator, and I'm in the process of trying to set up a direct development environment, on a PlayStation 3 system, so access to PowerPC toolchains isn't a problem.
Eventually, I'm planning on seeing if I can use the existing code, and parts of FreeBSD's PlayStation 3 port, to implement a basic, first-draft port to run on Sony's CellOS/BEAT ABI-based hypervisor, or in GameOS mode, with PetitBoot.
Thanks in advance, for any assistance,
Tyson Key.
