Enum x86_64::structures::gdt::Descriptor [−][src]
A 64-bit mode segment descriptor.
Segmentation is no longer supported in 64-bit mode, so most of the descriptor contents are ignored.
Variants
Descriptor for a code or data segment.
Since segmentation is no longer supported in 64-bit mode, almost all of code and data descriptors is ignored. Only some flags are still used.
A system segment descriptor such as a LDT or TSS descriptor.
Implementations
impl Descriptor
[src]
pub const fn kernel_code_segment() -> Descriptor
[src]
Creates a segment descriptor for a 64-bit kernel code segment. Suitable
for use with syscall
or 64-bit sysenter
.
pub const fn kernel_data_segment() -> Descriptor
[src]
Creates a segment descriptor for a kernel data segment (32-bit or
64-bit). Suitable for use with syscall
or sysenter
.
pub const fn user_data_segment() -> Descriptor
[src]
Creates a segment descriptor for a ring 3 data segment (32-bit or
64-bit). Suitable for use with sysret
or sysexit
.
pub const fn user_code_segment() -> Descriptor
[src]
Creates a segment descriptor for a 64-bit ring 3 code segment. Suitable
for use with sysret
or sysexit
.
pub fn tss_segment(tss: &'static TaskStateSegment) -> Descriptor
[src]
Creates a TSS system descriptor for the given TSS.
