PS5 Operating System
[edit]Hello,
I saw your post on Talk:PlayStation 5 and wanted to follow up with my own investigations on the matter. Not enough for a citation on Wikipedia, but it may help you in your search.
Most large multinational companies are fairly decent when it comes to abiding by open source licences. While it is known that FreeBSD was used on the PlayStation 4, they went out of their way to publish (some) of their source code changes (Even though the BSD licence doesn't require that) as seen here. https://doc.dl.playstation.net/doc/ps4-oss/index.html
The equivilent webpage for the PlayStation 5 has no listings explicitly related to an operating system, though this may just mean that Sony decided they didn't need to publish source code. I wouldn't say this rules out the use of BSD (Since they don't have to release changes), but It likely rules out the use of Linux, since I doubt they'd opt for the "mail us and we'll send you a CD with source" aproach when they already have a web portal set up. https://doc.dl.playstation.net/doc/ps5-oss/index.html
The best way to determine what open source software to use, if any, is to look at documentation shipped with the PS5. Most consumer devices have a page in their settings menu where open source attributions are listed. However I'm having trouble finding footage of this online, as it's not something most consumers ever seek out.
Hope this helps! --Mbrickn (talk) 10:29, 12 October 2021 (UTC)
- Hey thank you for the response. I followed your line of thinking and found out at that it includes the license for the FreeBSD kernel, version 11 released in 2016 to be precise. This is not definitive proof, as it could be a hybrid kernel, but it also uses BSD libc, so it is very likely the whole operating system layer is still BSD.
Thanks
