the short answer is linux follows standards, and is universal within the engineering teams responsible; far less effort to get working. big thing is that it's easier to "hire talent and hit ground running" in regards to progress
correct, i forgot some context about what i meant "apple developing", apple allowed raw images to be used now, this is what i described being used in the cpu manufacturing process for testing units. this was not always an option. i meant this pseudo-feature being made public, not asahi which has been public and apple has been aware of for over a year
hi, i can chime in and say this is a known fact. M1 is not OOTB IBM PC compatible (unlike almost all x86), which means no standard BIOS/UEFI firmware interface for bootloaders like grub etc. internally, there was some significant overhauls to the automated testing and silicon validation/quality control processes during development (well before pandemic) which resulted in a need for this. apple can validate their silicon, but foundries, factories and other third parties are typically not able to (without added cost, implementation, Apple intellectual property, etc), so developing this was cost beneficiary to apple and eases production, and is really just accordance with existing industry standards for CPU manufacturing. i am just surprised this was made public, the motive i do not know, but i hope this helps explain, it's my first comment on this site.
