Secure Monitor Calls

The secure monitor provides two top level handlers of which each provides a range of sub handlers.

Secure Monitor Calls follow the ARM SMC calling convention:

Bit number Bit mask Description
31 0x80000000 Set to 0 means Yielding Call; Set to 1 means Fast Call.
30 0x40000000 Set to 0 means SMC32 convention; Set to 1 means SMC64.
29-24 0x3F000000 Service Call ranges.
23-16 0x00FF0000 Must be zero.
15-0 0x0000FFFF Function number within the range call type.

Id 0

Cryptography related functions.
