Fedora 42 On 64-bit ARM Might Make It Seamless To Run x86/x86_64 Programs

[Ladis]

It is just another stupid idea. If you really need amd64 software - just buy this hardware, it will go fast and seamless. Emulation will not go efficiently. More over - arm is not efficient platform and offer zero to performance and have zero advantage over amd64. Emulators exist over than 20 years. Again? Good luck. It is useless. Completely.

PS: And even more useless is having ARM cpu on host. It is stupid in every way which never was designed to work fast. Good luck.

Were you in a cave? ARM is in the most selling laptops and in the biggest cloud. And recently in Windows laptops, it doesn't have the common problems like the performance when you unplug the power adapter or power consuption during sleep.

kinda funny that in the future

maybe in the future, but right now

Make up your mind.

They could have fixed GPUs booting off RPI5, due to no video codecs anymore present in the SoC it would be useful for some, I have GT710 around, it would be plenty.

I believe the situation with Fedora is "because of how crypto is considered a weapons technology for the purpose of export controls, wolfSSL has to go through the official process for thoroughly checking that it either doesn't do anything more than OpenSSL or that anything more that it does do is on the list of OK things to export".

There is required legal review for potentially patented algorithms, for example with ffmpeg.

About export controls, there was a statement from a FESCo member in the other dicussion thread, that the main issue was compliance with Fedora Crypto Policy (namely that WolfSSL adheres to user-configured crypto rules) and that Crypto Policy is what is compatible to US export law.

I mean, that can be said of any arch that gains moderate popularity, I would confidently say that "riscv will be the arch that runs everything" too. nothing will stop emulators emulating things that can be emulated.

maybe in the future, but right now: windows on arm runs x86 ootb, fedora on arm will run x86 ootb. and not the other way

kinda funny that in the future aarch64 will be the arch that "runs everything", which was the longest time the argument for x86

I have used qemu-user to run a proprietary aarch64 tool to update firmware on a usb chip on a RISC-V board.

Running x86 on ARM is so yesterday.

x86 emulation is not a crypto library, but the argument was:

so paraphrased, if QEMU is ok then all other software with the same function is also ok.

I however pointed out that this is not how WolfSSL was treated in Fedora (and this is what edxposed presumably wanted to say).
