[hpsdr] PS3 support in Linux 2.6 - Cool!

----------------------------------------
[Updated Dec. 7] -- Sony-contributed patches aimed at adding
machine-specific features for the PlayStation 3 (PS3) have been merged
into the stable 2.6.20 kernel tree. The patches should greatly
simplify maintaining Linux kernels for the PS3, which is already
supported by at least one Linux distribution.

Spread the word:

Linux gained generic support for the Cell processor, on which the PS3
is based, with the 2.6.13 release in June of 2005. The new
Sony-contributed patches to the 2.6.20 kernel appear to add
machine-specific support for technology such as the PS3's memory
architecture, DMA (direct memory access) model, and SMP (symmetric
multiprocessing) model.

A Yellow Dog Linux (YDL) distribution has been available for the PS3
since October, thanks to a development deal between Sony and YDL
publisher TerraSoft. However, YDL so far has not been bundled with
early PS3 shipments, despite earlier indications from Sony
Entertainment's CEO, Ken Kuturagi.

The new PS3 kernel patches should make supporting the PS3 under Linux
much simpler, since no external patches need be applied when creating
kernels for the machine. Applying such patches can complicate the
kernel build process, or even lead to conflicts, where more than one
set of patches is applied.

The PS3 patches can be browsed in Linus Torvalds's kernel tree, here.
