Sony's PS3 Drops Linux; Why You Should Care
3:30 AM - April 1, 2010 by Alan
Dang10035.html#>-
source:
Tom's Hardware US
When the PlayStation 3 launched in 2006, Sony touted Linux support as a
reflection of their commitment to making the PS3 a true supercomputer. In
fact, prior to launch, Ken Katuragi expressed his desire to pre-install
Linux on all PS3's. Though mostly marketing hyperbole, the vision of makin=
g
the PlayStation something bigger than just a gaming machine was part of the
company culture that permeated Sony's PlayStation division during the last
decade.
>
*The PlayStation Heritage*
During the peak of the original PlayStation era, Sony launched "Net Yaroze,=
"
a consumer development kit that allowed interested gamers to work on
developing their own applications for the console. In the PlayStation 2
era, Sony offered "Linux (for PlayStation 2)" a fully-fledged Linux
distribution which included an X-Server supporting the PS2's Graphics
Synthesizer and even some support through Mesa 3D. Unlike the Net Yaroze,
which required customized hardware and software, Linux for PlayStation 2
worked on the majority of retail PlayStation 2's. The real challenge was
finding a monitor that supported the PS2's Sync-on-Green signal.
By the time the PS3 was launched, Sony seemed to be on a progressive path o=
f
increasing support for the community of homebrew enthusiasts. Net Yaroze
opened up the idea, but required customized hardware and software. Linux
for PlayStation 2 allowed consumers to use retail consoles with a custom
kit. With the PS3, Sony promised something amazing: full Linux support
available on all shipping units -- just burn a DVD and install.
The homebrew market for the PS3 never caught on the way it was supposed to.
Due to concern for piracy, Sony disabled support for the RSX GPU via a
HyperVisor. When combined with the difficult-to-program Cell Broadband
Engine, the role for Linux on PS3 was limited as a gaming platform. On the
other hand, the Cell itself was a remarkable processor. In 2006, the Cell
offered 150 GFlops of single-precision computational performance. A modern
Core i7 975 only offers 111 GFlops of single precision performance. For
applications requiring single precision arithmetic, the PS3 offered an
exceptional bargain. In fact, it was Sony in early 2006 who approached
Stanford to discuss porting Folding-at-Home to the PlayStation 3.
While Kutaragi was the most prominent proponent of homebrew development, he
was not the only cheerleader. The other prominent figure during the
PlayStation Decade was Phil Harrison.
I first met Phil Harrison while still a student at Stanford, when he gave u=
s
a talk about the "Next Generation PlayStation." In his career at Sony, Phi=
l
Harrison would push for Linux and continue to open up the homebrew
capabilities of the PS3. He would later play an instrumental role in
supporting and promoting the homebrew nature of games such as "Little Big
Planet," and after moving to Atari, he continued to be vocal about
supporting the independent developer through tools such as the Unity Game
Engine.
From the launch of the PlayStation 3 in 2006 through 2010, Sony
incrementally added new features to the PS3. Compared to the initial PS3
launch, Sony has improved CD Audio performance with Super Bit Mapping, adde=
d
Video Chat, Folding-at-Home support, added videophile-grade video scaling and
deinterlacing, 1080p24 Blu-Ray playback, upscaled PSOne support, BD-Live, a=
n
improved photo gallery, and full screen Adobe Flash support. On queue is 3=
D
stereoscopic support. Unfortunately, Sony has since removed support for SAC=
D
playback as well as PS2 backwards compatibility with newer revisions of the
console.
*Today's Sony*
In the post-Kutaragi, post-Harrison PlayStation world it seems as if there
are fewer opportunities for the visionaries at Sony. The worldwide economi=
c
crisis has led companies to trim costs wherever possible. The PS3's overly
ambitious design, built during an era of seemingly unlimited economic
growth, has resulted in a console that is still sold at a loss. To tighten
the belt, Sony is pulling back from this community service endeavors.
On March 28, 2010, Sony announced that they would be pulling support from
Linux on the PlayStation
3l>.
This was due in part to Sony's HyperVisor being compromised, allowing
hackers direct-to-kernel and device driver "ring 0"
accesshtml?xtmc=3Dgeohot&xtcr=3D2>.
By dropping support for Linux, Sony increases the difficulty of pirating
downloading movies purchased or rented through the PlayStation Network.
Additionally, dropping "Other OS" support ensures that Sony no longer needs
to maintain the HyperVisor drivers for each firmware and hardware revision
of the PS3, ultimately delivering a cheaper and more profitable hardware
platform. *[Though famed iPhone hacker Geohot did pledge to try to retain
the Other OS feature through custom
firmware,10023.html?xtmc=3Dps3_linux&xtcr=3D1>.
-Ed]*
Today, the PS3 is a potent gaming machine. Games such as Final Fantasy XII=
I
are finally bringing to reality the movie-quality graphics once promised by
Sony. For hardware that is almost 4 years old, this is an impressive
achievement. Likewise, Kutaragi's dream to make the PS3 the media hub of
the home is becoming a reality. The open source PS3 Media Server allows th=
e
PS3 to be an exceptional media streamer particularly in the context of the
PS3=92s exceptional video scaling and noise reduction capabilities. Sony
already offers HD PVR support for digital TV in Europe and Japan, and if
Sony offered ATSC/CableCard support for US owners, I wouldn't need a HTPC.
*Does it Matter?*
The loss of Linux for the PlayStation
36331.html>is
less about running Linux on 4-year old hardware. As powerful as the
Cell
CPU once was, the future of homebrew vector programming and high-performanc=
e
scientific computing is going to be found in the world of the GPU and
technologies such as NVIDIA Fermi, AMD Cypress, and Intel Larrabee.
Instead, the loss of Linux represents the end of an era for PlayStation.
Through all of the hyperbole that characterized the PlayStation world of th=
e
last decade, there was a desire and passion to build something grander than
just a simple game machine.
We asked a Sony representative if there were plans to restore the "Other OS=
"
feature once the security risk had been analyzed and patched. The official
reply: "At this point in time, we have no plans to bring back the feature t=
o
the system."
While Sony is pulling away from Linux and the community, we can't help but
to think about the other end of the spectrum and a company that has fully
supported the enthusiast community: id Software.
Rather than increasing restrictions over time, id has a great history of *
decreasing* restrictions over time. One good example is how they release
the source code to their game engines via GPL after a reasonable amount of
time. If Sony were following id's model they would be opening up RSX
support in a future version of PS3 Linux as opposed to pulling it away.
I sent a few quick questions to John Carmack, co-founder of id software,
lead engineer of Armadillo Aerospace, Linux supporter, and an all-around
good guy to get his thoughts on the situation.
*Alan*: Have you ever regretted GPL'ing a game engine and feeling as if you
released it too early? Also, will we see still Doom 3's engine released
once the patented code is removed?
*John*: No, I have never regretted any GPL release. Yes, I still hope to
release the Doom 3 code sometime after Rage ships.
*Alan*: What's your thought on PS3 Linux story? Is there even a role for
scientific computing in a world of modern GPGPU's?
*John*: I never liked the Cell architecture. You can get high peak numbers
out of it, but software development time matters a lot, and not having
caches and virtual memory makes development take a lot longer, especially
for the majority of applications that don't fit neatly into the DMA pipelin=
e
model.
It probably isn't Sony's call alone with the RSX -- Nvidia probably would
not be supportive of the complete disclosure of RSX details.

*The PlayStation Heritage*
During the peak of the original PlayStation era, Sony launched "Net Yaroze,=
