Module arch_helpers 

Helper functions and types shared between multiple arch crates.

This function contains functions and types that do not have to be in the core kernel and are architecture-specific, but are shared by two or more arch crates. While these could also live in a dedicated crate, we use the kernel crate as all arch crates already depend on it.

Enums

TRD104SyscallReturn

System call return variants defined as defined in TRD104.

TRD104SyscallReturnVariant

Enumeration of the system call return type variant identifiers described in TRD104.

Functions

encode_syscall_return_trd104

Encode the system call return value into 4 registers, following the encoding specified in TRD104. Architectures which do not follow TRD104 are free to define their own encoding.

encode_upcall_trd104

Encode the upcall arguments into 4 registers compatible with TRD104.

encode_upcall_trd104_ptr^⚠

Encode the upcall arguments into 4 registers compatible with TRD104.

syscall_from_register_arguments_trd104

Helper function for converting raw values passed back from an application into a Syscall type.
