@teohhanhui I believe this is applicable to all our Linux targets. |
|
@teohhanhui In particular, please apply it to all tier 2 targets with a Linux kernel version specified. I believe there are a few tier 3 targets where I am less certain of this change, so I think we should hold off on those unless you can identify that they do work with the current kernel. |
And by association |
|
I believe the kernel has only recently dropped support for old, pre-i586 x86, and Itanium, so it should work for everything else. We don't really have any such targets (the i386 of Apple is a misnomer). |
|
There are a few RISCV targets which have gone in and out of functionality recently, despite being newer, for which I am less confident, which is why I suggested skipping tier 3. Anything like this sets off alarm bells:

There was a problem hiding this comment.
Anyone using x32 is having a cursed time, but they definitely shouldn't be cursed by being forced to use an even older kernel version than needed.

@workingjubilee I'll do some digging on this... |
|
I think the glibc and musl minimum kernel versions may differ for a target in practice |
|
Note that we wish to update the bundled musl soon: #125692 |
