#asahilinux

0 message0 participant0 message aujourd’hui

Looks like M4 support for #asahilinux is going be rather painful. We’re still focusing on upstreaming M1/M2 support but other people have been trying to bring up m1n1 on M4 and it looks like a few things changed:

When configuring a macho boot object we now get dropped into an environment where Apple’s SPTM is running in GL2 and we are supposed to talk to it from EL2 with MMU already enabled to setup pagetables. This neither works for Linux nor for running XNU under our hypervisor to reverse engineer the new hardware.

When configuring a raw boot object we’re dropped into EL2 with GL2 and most (all?) Apple specific extensions disabled. This is totally fine for Linux but we can’t run XNU under our hypervisor that we use to reverse engineer the hardware in this state. This also seems to be broken for >=15.2 right now because it probably isn’t very well tested 😕

Qualche anno fa sostenevo che #AsahiLinux fosse uno spreco di risorse, un (ammirevole) sforzo ingegneristico che avrebbe portato benefici quasi solo ad Apple, la quale avrebbe dovuto essere boicottata per la chiusura ostinata e l'ostruzionismo.

Continuo a sperare di sbagliarmi, ma tra persone che escono dal progetto e arretratezza dello sviluppo (ad oggi mi pare che supporti solo M1/2 e nemmeno al 100%) temo davvero che stia diventando un grande "ve l'avevo detto"

It's sad to see what's happening on @AsahiLinux , but the project has never made sense to me, apart from the developers having fun of doing it.

#Apple doesn't deserve that effort, it's too close of a company.

My opinion is the best the community does is not support Apple at all, and if someone wants to use Linux, let that person support a company that supports Linux somehow.

I have an #AppleSilicon #M1 and definitely my next hardware will not be Apple's anymore, I'm leaving the ecosystem to support other initiatives.

@mntmn is on my radar... I'm open to suggestions and opinions!

Thanks!

The cool thing I always find with reading up on #AsahiLinux's progress reports is the often, "elegant" solutions required/implemented by #Apple for their hardware (despite the jankiness of #macOS, honestly), and the Asahi Linux team reverse engineering and reimplementing it, bringing some of that "elegance" and brilliantly engineered/designed solutions over to #Linux (perhaps in a better way, working with retrospect and all).

Honestly this project is a win-win for a lot of parties - again, the (incredibly talented) Asahi team is able to replicate/reiterate on some of these brilliant designs Apple's done and bring them to Linux, both Apple and Linux itself have been receiving important reports of some well hidden bugs found by the Asahi team throughout their development, and
#Rust is becoming increasingly more present in the Linux kernel which as I've grown to understand is a very important "fight".

Heck, this project has even brought to light some of the
nasty parts of the Linux (development) community that a lot of users wouldn't have known about otherwise, which critically needs fixing.
