Module instructions

Special x86_64 instructions.

Modules

• interrupts
  Enabling and disabling interrupts
• port
  Access to I/O ports
• random
  Support for build-in RNGs
• segmentation
  Provides functions to read and write segment registers.
• tables
  Functions to load GDT, IDT, and TSS structures.
• tlb
  Functions to flush the translation lookaside buffer (TLB).

Functions

• bochs_breakpoint
  Emits a ‘magic breakpoint’ instruction for the Bochs CPU emulator. Make sure to set magic_break: enabled=1 in your .bochsrc file.
• hlt
  Halts the CPU until the next interrupt arrives.
• nop
  Executes the nop instructions, which performs no operation (i.e. does nothing).
• read_rip
  Gets the current instruction pointer. Note that this is only approximate as it requires a few instructions to execute.
