Do we really need a UEFI replacement?

[–] DarkAri@lemmy.blahaj.zone 7 points 17 hours ago

Yeah we should replace it with legacy bios.

Probably not. At least not right now. But China needs one apparently.

My thoughts are "Why do they need one?". It's not like UEFI stops you doing anything.

UBIOS's unique features over UEFI include increased support for chiplets and other heterogeneous computing use-cases, such as multi-CPU motherboards with mismatching CPUs, something UEFI struggles with or does not support. It will also better support non-x86 CPU architectures such as ARM, RISC-V, and LoongArch, the first major Chinese operating system.

[citation needed]

I would say this is about increasing the level of control of the platform, not about technological issues.

Edit: For example, here's the RISC-V UEFI specification.

It's about having a home grown option. Can't trust Americans not to backdoor everything, and that generally conflicts with China's desire to backdoor everything.

[–] WhyJiffie@sh.itjust.works 2 points 9 hours ago

america cannot really backdoor a specification. uefi is not software, but a specification, upon which firmwares can be built. that's another story that we happen to be calling the firmware on our computers "the uefi", but really there are quite a few different proprietary uefi implementations out there already.

so, if that ws the reason, they could have just created their own UEFI firmware, and not something different

Control is the most important thing to the CCP so it makes complete sense from their perspective. We would be free to buy into it but they would definitely force it on devices within China.

For x86 or ARM?
