Yellow Dog Linux booting up on a PS3

OtherOS is a feature available in the first versions of the PlayStation 3 gaming console that allowed Linux operating systems to be installed on the system. This feature was made unavailable in newer models and removed from the oldest ones through a firmware update by Sony.

The PlayStation 3 Slim model removed the possibility to install Linux or any other operating systems that used the "Other OS" feature.[1] The "Other OS" feature is disabled by firmware version 3.21 but still runs on older consoles that have firmware 3.15 or lower[2]. However, on March 30, 2010 George Hotz (aka geohot) stated his intention to create a custom firmware for the PS3 to counter this move[3][4], warning gamers not to update their systems until he finds a way to keep the Other OS option on the PlayStation 3. Additionally, a class action lawsuit has been filed for those who wish to pursue legal remedies.(see Playstation 3 System Software)

PS3 customers in Europe who bought the system from Amazon have received partial refunds in accord with European law that requires products to perform advertised functions[5].

Any Linux operating system had access to 6 of the 7 Synergistic Processing Elements;[6] Sony implemented a hypervisor restricting access to the RSX. IBM provided an introduction to programming parallel applications on the PlayStation 3.[7]

History

Since the millenium, Sony has used the fact that the PlayStation 2 can run Linux in its marketing. They promoted the release of the PS2 Linux Kit, which included a Linux-based operating system, a USB keyboard and mouse, a VGA adapter, a PlayStation 2 Ethernet network adapter, and a 40 GB hard disk drive (HDD).

The PlayStation 3 did not pre-install include Linux. However, Sony included an option in the XMB menu to install other operating systems such as Linux.[8] Sony stated, "It was fully intended that you, a PS3 owner, could play games, watch movies, view photos, listen to music, and run a full-featured Linux operating system that transforms your PS3 into a home computer."[9]

Soon after the PlayStation 3 launched, Sony released "Other OS" in a PlayStation 3 System Software firmware up-date that allowed booting into Linux from the hard drive or from a Live CD that the distributor's kernel would boot.

Sony removed support for the "Other OS" install option in the PS3 Slim, announced in August 2009.[10] In March 2010 Sony announced that the "Other OS" capability of the original PS3 models would be removed due to security concerns in PS3 Firmware 3.21 on April 1 2010.[11]

Several methods of bypassing the updating and retaining the ability to sign into PSN have been discovered, most involve using third party DNS servers[12], although this is clearly a breach of PSN terms and conditions and may therefore result in console bans.[citation needed]

Geohot claims to have created custom firmware for the PS3 called 3.21OO that re-enables OtherOS and has published a video of his Custom Firmware as proof.[13]

On April 27, 2010 a class action lawsuit was filed in California. The lawsuit claimed that the removal of the OtherOS feature was "unfair and deceptive" and a "breach of good faith".[14] Most of the filing relates to violation of various consumer protection laws relating to the removal. Two other lawsuits were also filed and are somewhat similar in nature but are filed by other individuals.[15]

Kernel

Linux supported PlayStation 3 with version 2.6.21. No patches or modifications are required.[16] A simple Linux add-on CD for the PS3 includes support for Fedora 8 and other operating systems that already claim to install natively on the PS3.[17] However, there is currently an issue with the latest kboot[clarification needed] boot loader provided by kernel.org. Once the user selects the default action, the USB ports are de-registered on some systems. A work-around is available on at PSUbuntu[citation needed].

Distributions

Debian,[18] Fedora 8,[19] Gentoo,[20] OpenSUSE and Ubuntu[21] run on the PlayStation 3.[22] Yellow Dog Linux for the PlayStation 3 was first released in late 2006.[23]

Ubuntu

Some versions of Ubuntu up to the release 9.10 have been ported to the PS3 platform.[24] The installer cannot run in Live mode when running in 480i or 480p video resolutions, but it offers an text-based installer that installs fully functional Ubuntu. It is possible to mount an external USB hard drive as the home folder during install.

The LTS release 8.04 (Hardy Heron) of Ubuntu is incompatible with the PS3. However the 8.10 (Intrepid Ibex) release was ported to the PS3 on the same release date as the official main Ubuntu release.[25]

Yellow Dog Linux

Yellow Dog Linux 5.0 was one of the first Linux distributions to run on Sony's PlayStation 3 platform.[26] It is designed specifically for HDTV so users with SDTV will have to use the commands 'installtext' and 'ydl480i' to install and run.[27]

Yellow Dog Linux is based on the Red Hat Enterprise Linux/CentOS core and relies on the RPM package manager. Digital audio has been verified to function properly, however, the Nvidia graphics card is not supported beyond framebuffer mode. In addition, some other hardware components will not function properly without modifications to the kernel. WiFi functionality via the Network Manager is also not fully supported and must be entered manually via the Network Configuration tool, or in some cases, through the command shell.[28] A workaround is available to enable wireless to be configured via the Network Manager.[29]

OpenSUSE

OpenSUSE 10.3 was the first version of OpenSUSE to run on the Sony PlayStation 3 platform. OpenSUSE is a free version of SUSE Linux, which is owned by Novell. There are PlayStation 3 specific installation instructions available for OpenSUSE.[30]

Starting with OpenSUSE 11.2, support for the PowerPC (and therefore the PlayStation 3) has been dropped.[31]

Fedora

Fedora also ran on the PlayStation 3. On a CECHExx PS3 with firmware 2.01, Fedora 7 works on a USB external hard disk but fails to detect the internal disk, Fedora9 detects the internal disk but not the USB disk, Fedora8 will not work due to video "card" detection problems. Fedora 10 installs on the internal hard disk without any issues and works fine without having to change any settings.

Fedora 12 only installs on the Playstation 3 when running the 64 bit kernel and only when English is the chosen language.[32]

RSX Homebrew

Linux on the PlayStation 3 allows for a range of homebrew programs to be developed. Although the Cell's performance is more than enough to handle most media requirements or render complex 3D graphics, it does lack the teraflops performance of a contemporary GPU's texture fetching hardware. For this reason many complex games aren't possible on the PlayStation 3 through Linux, as access to hardware acceleration in the RSX is restricted by a hypervisor.

There have been developments in enabling access to the RSX through the Linux kernel and the X Window System.[33] It's possible to use the RSX memory as swap space. A trick to access some 3D functions was blocked with firmware 2.10.
