Add support for PS3

Has a Patch: no Platform: PowerPC

Description (last modified by wkornewald)

PowerPC support should arrive after R1, the PS3 could be an ideal target for Haiku due to its multi-threaded architecture, ie. translators and libraries could be optimized to use the Cell, giving the whole OS and applications that use the optimized components a performance boost.

Areas that need looking into are:

  • How does the boot process work
  • What devices are presented to an OS
  • What components of Haiku can be optimized to use the Cell BBE's SPU's
  • Is the memory layout to restrictive to make a port whorthwile

Note to anyone reading this - don't get excited - this isn't someone working on a PS3 port. Its not news. Nothing may come out of this.

Boot process:

There are two components OtherOS.self and OtherOS.bld. OtherOS.self is the component that adds itself to the XMB and can be downloaded from Sony #1. 1.60 and later revisions of the PS3 firmware include the option on the XMB by default.

The OtherOS menu option boots otheros.bld that can be stored on a CDROM, DVD, or a compatible memory card. The device has to have the following directory structure on it and uses a FAT32 file system:

<device>/PS3/ <device>/PS3/otheros/ <device>/PS3/otheros/otheros.bld

The OtherOS.bld for Linux is a gzipped image containing a kernel and an initrd. Is we were booting Haiku on the PS3 in the "supported" way, we can ignore the OtherOS.self, and just (Ha! *just*) build a Haiku OtherOS.bld.

The ps2dev.org team look like they are documenting the hypervisor system calls:

Given that the ps3 slim will no longer have "other OS" support... is this still a want?

comment:5 Changed 10 years ago by jackburton

Yeah, I'm tempted to close this as "invalid".

given the PS3 fat also no longer has an "other OS" option... this should definitely be closed.
