PlayStation 3 Support Is Still Being Worked On Within The Linux Kernel
While Sony long ago removed the "Other OS" functionality from the PlayStation 3, it seems some open-source developers are still working on the PS3 support for Linux.
Geoff Levand landed a few PS3 kernel patches for mainline Linux kernel integration via the 3.20 POWER pull request.
In terms of what these new PS3 patches allow, Geoff explained recently, "It will allow a kexec based bootloader (petitboot for example) to pre-allocate a highmem region and store things like an initrd or other large data needed to boot an OS. With some PS3 configurations the boot memory region is not large enough to fit all the boot data."
