The announcement is vague, the link gives 404. However, still somebody made a first move to port Linux to the recently announced M1 Chip, that will power future generations of Apple notebook devices. The community criticizes the approach: the port comes in a single patch with no documentation. Given the size of the patch this is pretty difficult to comprehend. Plus, the patch requires third party code, that apparently is not committed to git.
To conclude, this is a twofold message: while it’s good to see such developments and have Linux ported to such hardware, the approach indeed is difficult. On a more positive note, there are other working groups still motivated enough to work on a more complete port.
