Re: Implementation question

 | I just read an article (http://www.execpc.com/~halkun/PS2) that tells that
 | the PS2 Linux uses some proprietary software interface to access the
 | hardware, and that this software interface (Runtime Environment, RTE) is
 | not available in source - sort of like OpenFirmware.
 | Does the NetBSD/playstation2 port use that same software interface
 | (RTE) as well?

NetBSD/playstation2 use RTE to access IOP devices. ohci driver use
it for DMA.
sys/arch/playstation2/playstation2/sifbios.c is interface of it.
