He is not wrong. The initial RAM has LPAR address 0-0x7ffffff. Note that the dmesg printout relating to the initial RAM gives the _top_ address of RAM (0x7ffffff+1), not the start of it.

Well, what Linux does with it is a question which might be better asked in the Linux forum. With a 2.6.28.10 kernel at least, the 112M gets added to the regular memory pool so that you can malloc() from them: miu:~% uname -a Linux miu 2.6.28.10 #1 SMP Sun Jul 5 12:11:51 CEST ...

The first 128M can be accessed either in real mode (using effective address 0 - 0x7ffffff), or by using the MMU to map LPAR address 0 - 0x7ffffff to some virtual address range of your choice (see lv1_write_htab_entry et al). The remaining 112M can be allocated using the lv1_allocate_memory HV call. ...

@rapso: If you don't want to use the MMU driver, that's fine. Just don't call ps3MmuInit () and ps3MmuOn(), and you'll get your flat memory model. Note however that due to the way hardware virtualization works in the Cell, the flat memory model contains 128MB of RAM _only_. No video memory, no USB r...

Yup, then information in the wiki is more than adequate (you actually only need <name, id, # of inputs, # of outputs> for each call).

@jbit: Yes, that's why I mentioned this issue with the existing USB driver.

I've reused the LICENSE from the PSPSDK.

Currently I have lv1callarg.h, lib1calltab.h and hv.S still copied from Linux for generating
the HV call stubs, so I guess another work package would be to cleanroom that.

PS3SDK collaboration invitation

Well, we've all heard the rumors about ongoing PS3SDK development efforts, but so far nobody has shown any code. I think the main problem with getting a PS3SDK out the door is that it's a rather large project for one or two persons to undertake, so eventually anyone who tries on his own will get stu...

Putting an SPU into isolation mode does not give it access to any extra data. It only prevents _others_ from accessing what that SPU already has.
Thus a key-cracking application will not benefit from running in isolation
mode.

Re: PS3 Hardware Questions

The specs say there are 4 USB ports, and there are. They are attached to the root hub, just like in a normal PC. That's not true, for the 60GB model at least. There are two USB channels, each with a 2 port root hub. But the 4 USB ports on the front are not connected directly to any root hub, but to...

It also says that lv2_kernel.self is the GameOS, so presumably it is not loaded at all when
the system is configured for OtherOS operation, but only the lv1 stuff. And that would
be why the Linux code only contains lv1 calls; there is no lv2 loaded to call.
