| # SMCCC and PSCI functions for bare-metal Rust on aarch64 |
| |
| [](https://crates.io/crates/smccc) |
| [](https://docs.rs/smccc) |
| |
| 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 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. |
| |
| This is not an officially supported Google product. |
