This article introduces to you whether the Linux 5.13-rc1 release initially supports Apple M1 chip, the content is very detailed, interested friends can refer to, hope to be helpful to you.

The long-awaited Linux support for Apple M1 finally has a preliminary result, and the newly released 5.13-rc1 begins to initially support M1. This group of patch is mainly from Hector Martin:

Hector Martin "marcan" leads a project called Asahi Linux that is dedicated to providing Linux support for MAC:

According to cover-letter 's description,

Https://lore.kernel.org/lkml/20210402090542.131194-1-marcan@marcan.st/

The main functions of this group of patch are as follows:

UART (samsung-style) Serial Port driver with earlycon support

Apple interrupt controller that supports interrupts, interrupt affinity (affinity) and IPI (cross-CPU interrupts)

SMP (supported by standard spin-table)

Framebuffer driver based on simplefb

Device tree of Mac Mini

Interrupt controller, M1 obviously does not use GIC, so in addition to the basic peripherals, the architecture-related new code drivers/irqchip/irq-apple-aic.c becomes the largest patch in this patchset, adding 864 lines of code.

At present, this group of patch can realize Mac Mini boot to Framebuffer and serial port console. Of course, there is still a long way to go. If you need to try, you can follow the documentation:

To try.

According to our work experience in a chip company, its current state should be a very early stage, similar to when we get a FPGA and start bring-up Linux, it starts with a serial port, an interrupt controller, or maybe a basic Framebuffer. In other words, you can't expect Linux to be really available at this stage.

But after all, this work has already begun, and we will continue to look forward to it.

On the release of Linux 5.13-rc1 whether the initial support for Apple M1 chip is shared here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
