Struct Command 

pub struct Command<'a, T: Id> {
    pub code: u32,
    pub data: u64,
    pub error: u32,
    /* private fields */
}

The Rust-flavored, FFI-friendly version of struct sev_issue_cmd which is used to pass arguments to the CSV ioctl implementation.

This struct is defined in the Linux kernel: include/uapi/linux/psp-sev.h

Fields

code: u32

data: u64

error: u32

Implementations

impl<'a, T: Id> Command<'a, T>

pub fn from_mut(subcmd: &'a mut T) -> Self

Create an CSV command with the expectation that the host platform/kernel will write to the caller’s address space either to the data held in the Command.subcmd field or some other region specified by the Command.subcmd field.

pub fn from(subcmd: &'a T) -> Self

Create an CSV command with the expectation that the host platform/kernel WILL NOT mutate the caller’s address space in its response. Note: this does not actually prevent the host platform/kernel from writing to the caller’s address space if it wants to. This is primarily a semantic tool for programming against the CSV ioctl API.
