Struct x86_64::msr::MsrHandlers

pub struct MsrHandlers {
    pub handler: BTreeMap<u32, (MsrRWType, Rc<RefCell<Box<dyn MsrHandling>>>)>,
    pub msr_file: Rc<RefCell<BTreeMap<usize, Rc<MsrDevFile>>>>,
}

MSR handler configuration. Per-cpu.

Fields

handler: BTreeMap<u32, (MsrRWType, Rc<RefCell<Box<dyn MsrHandling>>>)>

Store read/write permissions to control read/write brfore calling MsrHandling trait.

msr_file: Rc<RefCell<BTreeMap<usize, Rc<MsrDevFile>>>>

Store file descriptor here to avoid cache duplicate descriptors for each MSR. Only collect descriptor of ‘passthrough’ handler, since ‘emulate’ uses descriptor only once during initialization.

Implementations

impl MsrHandlers

pub fn new() -> Self

pub fn read(&self, index: u32) -> Option<u64>

pub fn write(&self, index: u32, data: u64) -> Option<()>

    &mut self,
    index: u32,
    msr_config: MsrConfig,
    cpu_id: usize
) -> Result<(), MsrExitHandlerError>

Trait Implementations

impl Default for MsrHandlers

fn default() -> MsrHandlers

Returns the “default value” for a type.
