Can someone tell me why it is technically challenging to run Linux on PS4 when PS4 already runs Orbis OS which is a fork from FreeBSD?

It's technically challenging to run anything on the PS4 because of code signing.

#43I have no idea about this stuff, how far towards a jailbreak/softmod is this? Could this exploit be locked out on quasi-everyone's PS4 via a simple PSN Update?
That they have gotten this unsigned code running means they have jailbroken it. This WebKit exploit might be patched but there are almost certainly more holes to be exploited.

It already is: this is based on a webkit exploit working only on older firmwares.

#45Framebuffer and KMS working. I wonder if the radeon driver could be patched among the Xorg one to get some 3D acceleration support.
Considering that tweet it's totally possible: https://twitter.com/fail0verflow Xorg changes not really required because AMD GPUs work just fine on top of modesetting driver.
And what about MESA?

Talk to some game devs sometimes, they don't think of it like a PC at all(which is why PC -> console is so hard and not vice versa). I doubt we'll ever see this for titles that extract every ounce of performance out of a platform.
Man, this is the fourth time today that someone's suggested that maybe I should talk to a real game developer about something. I am a game developer. Just not a (modern) console game developer. But I did develop SNES games, way back when! My point was not that this might be possible now ; but that, as console CPU+GPU power approaches a certain threshold of "good enough; why would we need more?", console makers will e…
> There's no hardware to think about in the Cafe toolchain—no IO ports to peek and poke, no MSRs to read off. There's just library APIs. It's nearly as abstract as Apple's tvOS SDK.
That's why CEMU is so advanced.

#47Wait wait wait, HDD support through USB? Are you serious? Any hardware manufacturers care to explain why this might be the case?

There had been library API on PS1, PS2 had been an exception with the DMA chains and VU code exposed to developers but Xbox 1 and all later consoles come with libraries and no poking into registers business. So you can already try your idea by writing an Xbox 1 emulator (which is as much a PC as PS4 or Xbone). Spoiler alert: these libraries are statically linked on top of developers going around them all the time. Ultra High Level emulation seems to work only on Nintendo consoles, see https://en.wikipedia.org/wiki/UltraHLE

#49Hackers gonna hack. Every generation of these consoles is a new challenge to all the hackers out there. You've got to think that the engineers who designed these systems eventually get "engineering syndrome" from staring at these systems for years and eventually start to be blind about tiny problems. Corporations put millions and millions of dollars behind the design of these systems and a ragtag group of folks comes in here and owns everything you worked to protect. I guess the only thing these hackers have over Sony is time. More time than money..and a fresh pair of eyes.
Is there a future with an open gaming platform like the Steam Machine? Why do developers choose a closed platform like PS4 vs the Steam Machine? What's there to protect that they work so hard to guard it?
Beautiful work here. Keep on hacking.

#50Can someone tell me why it is technically challenging to run Linux on PS4 when PS4 already runs Orbis OS which is a fork from FreeBSD?
The challenge is finding an exploit to load up linux instead of the signed, stock operating system.
