Crate x86

Modules

apic

Register information and driver to program xAPIC, X2APIC and I/O APIC

bits16

Data structures and functions used by 16-bit mode.

bits32

Data structures and functions used by 32-bit mode.

bits64

Data structures and functions used by IA-32e but not Protected Mode.

controlregs

Functions to read and write control registers. See Intel Vol. 3a Section 2.5, especially Figure 2-7.

cpuid

Support for the CPUID instructions.

current

A short-cut to the architecture (bits32 or bits64) this crate was compiled for.

debugregs

Functions to read and write debug registers.

dtables

Functions and data-structures for working with descriptor tables.

fence

irq

Shared interrupt description and set-up code. See the bits*::irq modules for arch-specific portions.

msr

MSR value list and function to read and write them.

random

Instructions to generate random bits directly from the hardware (RDRAND and RDSEED).

segmentation

Functionality to manipulate segment registers, build segement descriptors and selectors.

task

Helpers to program the task state segment. See Intel 3a, Chapter 7

time

Functions to read time stamp counters on x86.

tlb

Functions to flush the translation lookaside buffer (TLB).

vmx

Data structures and definitions used by Virtual Machine Extensions.

Macros

int

Generate a software interrupt. This is a macro argument needs to be an immediate.

syscall

Enums

Ring
