Apple M* CPUs do not have anything like that.
Their coprocessors are not higher-privileged. On the contrary, they are all isolated from AP, each other and main memory (by IOMMU).
- smaudet 4y agoHmm. If Apple were easier to develop on I'd consider buying their M chip laptops for that reason alone. My issue last I worked with one was that userspace was ridiculously restricted - they have made it antagonistically difficult to do anything on a Mac. Normal PC, despite the nonsense in the hardware, remains fairly easy to work with, as long as you aren't doing security critical stuff.
