Crate smccc

Functions for version 1.4 of the Arm SMC Calling Convention and version 1.1 of the Arm Power State Coordination Interface (PSCI) version 1.1, and relevant constants.

Note that the PSCI and SMCCC arch calls may be made via either HVC or SMC. You can choose which one to use by passing either Hvc or Smc as a type parameter to the relevant function.

This crate currently only supports aarch64 and the SMC64 versions of the PSCI calls, in the cases that both SMC32 and SMC64 versions exist.
