pub struct GS;

Expand description

GS Segment

Only base is used in 64-bit mode, see Segment64. In kernel-mode, the GS base often points to a per-cpu kernel data structure.

Implementations

source

impl GS

source

pub unsafe fn swap()

Swap KernelGsBase MSR and GsBase MSR.

Safety

This function is unsafe because the caller must ensure that the swap operation cannot lead to undefined behavior.

Trait Implementations

source

impl Debug for GS

source

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter. Read more

source

impl Segment for GS

source

fn get_reg() -> SegmentSelector

Returns the current value of the segment register.

source

unsafe fn set_reg(sel: SegmentSelector)

Reload the segment register. Depending on the segment, this may also reconfigure the corresponding segment. Read more

source

fn read_base() -> VirtAddr

Reads the segment base address Read more

source

unsafe fn write_base(base: VirtAddr)

Writes the segment base address Read more
