Syscall Register: SFMASK

Implementations§

§

impl SFMask

pub const MSR: Msr

The underlying model specific register.

§

impl SFMask

pub fn read() -> RFlags

Read to the SFMask register. The SFMASK register is used to specify which RFLAGS bits are cleared during a SYSCALL. In long mode, SFMASK is used to specify which RFLAGS bits are cleared when SYSCALL is executed. If a bit in SFMASK is set to 1, the corresponding bit in RFLAGS is cleared to 0. If a bit in SFMASK is cleared to 0, the corresponding rFLAGS bit is not modified.

pub fn write(value: RFlags)

Write to the SFMask register. The SFMASK register is used to specify which RFLAGS bits are cleared during a SYSCALL. In long mode, SFMASK is used to specify which RFLAGS bits are cleared when SYSCALL is executed. If a bit in SFMASK is set to 1, the corresponding bit in RFLAGS is cleared to 0. If a bit in SFMASK is cleared to 0, the corresponding rFLAGS bit is not modified.

pub fn update<F>(f: F)
where F: FnOnce(&mut RFlags),

Update the SFMask register.
