(X86) Generic Low-level Definitions

 

This section covers useful macros, definitions, and routines that are specific to the Intel x86 processor architecture but that are independent of the interrupt control, bus structure, and other ancillary functions traditionally associated with a ``PC.'' Those facilities are covered in section 10.4.

• 10.3.1 asm.h: assembly language support macros
• 10.3.2 eflags.h: Processor flags register definitions
• 10.3.3 proc_reg.h: Processor register definitions and accessor functions
• 10.3.4 debug_reg.h: Debug register definitions and accessor functions
• 10.3.5 fp_reg.h: Floating point register definitions and accessor functions
• 10.3.6 far_ptr.h: Far (segment:offset) pointers
• 10.3.7 pio.h: Programmed I/O functions
• 10.3.8 seg.h: Segment descriptor data structure definitions and constants
• 10.3.9 gate_init.h: Gate descriptor initialization support
• 10.3.10 trap.h: Processor trap vectors
• 10.3.11 paging.h: Page translation data structures and constants
• 10.3.12 tss.h: Processor task save state structure definition
