Enumeration Type Documentation

enum Zygoma::ia32::Faults

Intel Protected-mode exceptions and interrupts. Enumeration values: kFAULT_DIVIDE_ERROR  DIV and IDIV instructions. kFAULT_RESERVED_1  For Intel use only. kFAULT_NMI  Nonmaskable external interrupt. kFAULT_BREAKPOINT  INT 3 instruction. kFAULT_OVERFLOW  INT 0 instruction. kFAULT_BOUND_EXCEEDED  BOUND instruction. kFAULT_INVALID_OPCODE  UD2 instruction or illegal opcode. kFAULT_DEVICE_NOT_AVAILABLE  No math coprocessor + WAIT/FWAIT. kFAULT_DOUBLE_FAULT  Any instruction. kFAULT_SEGMENT_OVERRUN  Floating point instruction. kFAULT_INVALID_TSS  Task switch or TSS access. kFAULT_SEGMENT_NOT_PRESENT  Caused by memory access. kFAULT_STACK_SEGMENT_FAULT  Caused by stack operations. kFAULT_GENERAL_PROTECTION  Any memory reference can cause this. kFAULT_PAGE_FAULT  Any memory reference. kFAULT_RESERVED_15  kFAULT_FPU_ERROR  x87 FPU error ow WAIT/FWAIT. kFAULT_ALIGNMENT_CHECK  Any data reference in memory. kFAULT_MACHINE_CHECK  System dependent. kFAULT_SIMD_EXCEPTION  SSE and SSE2 fp instructions. kFAULT_RESERVED_20

Function Documentation

std::ostream& Zygoma::ia32::operator<< (  std::ostream &  ostr, const IDT &  idt )  [inline]

Dumps an interrupt descriptor table to an output stream. Parameters: ostr  [INOUT] The output stream. idt  [IN] The interrupt descriptor table. Here is the call graph for this function:

std::ostream& Zygoma::ia32::operator<< (  std::ostream &  ostr, const InterruptGate &  gate )  [inline]

Dumps an interrupt gate to an output stream. Parameters: ostr  [INOUT] The output stream. gate  [IN] The interrupt gate.
