# SMCCC and PSCI functions for bare-metal Rust on aarch64

|
|
This crate provides support for the Arm SMC Calling Convention version 1.4, including standard Arm
|
|
Architecture Calls constants, and version 1.1 of the Arm Power State Coordination Interface (PSCI).
|
|
It includes constants, functions to make the calls (on aarch64 targets), and error types.
|
|
|
|
Note that PSCI and other SMCCC calls may be made via either HVC or SMC. You can choose which one to
|
|
use by building this crate with the corresponding feature (i.e. `hvc` or `smc`). By default `hvc` is
|
|
enabled. If neither feature is enabled then the functions to make calls will not be available, but
|
|
the constants are still provided.
|
|
|
|
This crate currently only supports aarch64 and the SMC64 versions of the various calls, in the cases
|
|
that both SMC32 and SMC64 versions exist.
|
|
|
|
This is not an officially supported Google product.
