Members

Rax

The accumulator register.

Rbx

The base register.

Rcx

The count register.

Rdx

The data register.

Rsi

The source index register.

Rdi

The destination index register.

Rbp

The base pointer register.

Rsp

The stack pointer register.

R8

The general purpose register R8.

R9

The general purpose register R9.

R10

The general purpose register R10.

R11

The general purpose register R11.

R12

The general purpose register R12.

R13

The general purpose register R13.

R14

The general purpose register R14.

R15

The general purpose register R15.

Cs

The code segment register.

Ds

The data segment register.

Ss

The stack segment register.

Es

The extra segment register.

Fs

The general purpose segment register FS.

Gs

The general purpose segment register GS.

Reserved

Reserved for system use.

Rflags

The flags register.

Eip

The instruction pointer register.

Cr0

The control register 0.

Cr1

The control register 1.

Cr2

The control register 2.

Cr3

The control register 3.

Cr4

The control register 4.

Cr8

The control register 8.

Gdtr

A WHEA128A structure that contains the state of the global descriptor table register. The WHEA128A structure describes a 128-bit value and is defined as follows:

typedef struct _WHEA128A {
  ULONGLONG  Low;
  LONGLONG  High;
} WHEA128A, *PWHEA128A;

Low

The low order 64 bits of the 128-bit value.

High

The high order 64 bits of the 128-bit value.

Idtr

A WHEA128A structure that contains the state of the interrupt descriptor table register. For a description of the WHEA128A structure, see the description for the Gdtr member.

Ldtr

The local descriptor table register.

Tr

The task register.

Remarks

If the RegisterContextType member of a WHEA_XPF_CONTEXT_INFO structure is set to XPF_CONTEXT_INFO_64BITCONTEXT, the RegisterData member of that structure contains a WHEA_X64_REGISTER_STATE structure.
