AMX instructions are available in EL0 yes, and are used by CoreML and Accelerate.framework. A sample instruction: 20 12 20 00... which doesn't in any stretch parse as a valid arm64 instruction in the Arm specification. Edit: Some other AMX combinations off-hand: 00 10 20 00 21 12 20 00 20 12 20 00 40 10 20 00
