At the 2010 Chaos Communication Congress, fail0verflow (that’s a zero, not the letter O) demonstrated their jailbreak of the PS3. At the 2013 CCC, fail0verflow demonstrated console hacking on the Wii U. In the last two years, this has led to an active homebrew scene on the Wii U, and the world is a better place. A few weeks ago, fail0verflow teased something concerning the Playstation 4. While this year’s announcement is just a demonstration of running Linux on the PS4, fail0verflow can again claim their title as the best console hackers on the planet.
Despite being able to run Linux, there are still a few things the PS4 can’t do yet. The current hack does not have 3D acceleration enabled; you won’t be playing video games under Linux with a PS4 any time soon. USB doesn’t work yet, and that means the HDD on the PS4 doesn’t work either. That said, everything to turn the PS4 into a basic computer running Linux – serial port, framebuffer, HDMI encoder, Ethernet, WiFi, Bluetooth, and the PS4 blinkenlights – is working.
Although the five-minute lightning talk didn’t go into much detail, there is enough information on their slides to show what a monumental task this was. fail0verflow changed 7443 lines in the kernel, and discovered the engineers responsible for the southbridge in the PS4 were ‘smoking some real good stuff’.
This is only fail0verflow’s announcement that Linux on the PS4 works, and the patches and bootstrap code are ‘coming soon’. Once this information is released, you’ll need to ‘Bring Your Own Exploit™’ to actually install Linux.
