A new status report has been published by the developers of “Asahi Linux” that are continuing to work on providing Linux support for the Apple Silicon initially with the M1 SoC.
– Initial support for Apple M1 in Linux 5.13.
Asahi Linux continues making progress on enabling the Apple M1 under Linux. Some of the work they’ve been tackling this summer includes:
– The reverse-engineering work continues. Besides blind proving, helping in reverse-engineering for more advanced components has been helped by leveraging their custom hypervisor atop the project’s m1n1 bootloader with macOS on top. The m1n1-based hypervisor in turn has various debugging features for helping to reverse-engineer, tracing, and providing low-level debugging capabilities.
– when the DCP support is sorted out, due to resources they will likely end up only supporting certain firmware versions of it. The DCP firmware version does change and due to the battle of bringing up and maintaining the support, they are likely only to target a subset.
– One of the areas seeing a lot of reverse engineering work is on their DCP display engine co-processor. While there has been the early “Asahi” work within Mesa, they still need to ultimately assemble a Linux kernel DRM driver for the display and 3D graphics capabilities.
– There is also work on creating an Asahi Linux installer for deploying the Linux environment on the Apple Silicon hardware. The installation is tricky due to needing to create a “macOS” installation so Apple will recognize it as a bootable operating system.
– For Linux 5.15 the M1 DART driver is likely to land that in turn is required for PCIe, USB, DCP, and other functionality moving forward.
- Reverse engineering and Linux installation on Apple Silicon M1 is still ongoing.
