## Name

VkDeviceFaultAddressTypeEXT - Page fault access types

Loading… please wait.

## C Specification

Possible values of VkDeviceFaultAddressInfoEXT::`addressType` are:

    // Provided by VK_EXT_device_fault
    typedef enum VkDeviceFaultAddressTypeEXT {
        VK_DEVICE_FAULT_ADDRESS_TYPE_NONE_EXT = 0,
        VK_DEVICE_FAULT_ADDRESS_TYPE_READ_INVALID_EXT = 1,
        VK_DEVICE_FAULT_ADDRESS_TYPE_WRITE_INVALID_EXT = 2,
        VK_DEVICE_FAULT_ADDRESS_TYPE_EXECUTE_INVALID_EXT = 3,
        VK_DEVICE_FAULT_ADDRESS_TYPE_INSTRUCTION_POINTER_UNKNOWN_EXT = 4,
        VK_DEVICE_FAULT_ADDRESS_TYPE_INSTRUCTION_POINTER_INVALID_EXT = 5,
        VK_DEVICE_FAULT_ADDRESS_TYPE_INSTRUCTION_POINTER_FAULT_EXT = 6,
    } VkDeviceFaultAddressTypeEXT;

## Description

- `VK_DEVICE_FAULT_ADDRESS_TYPE_NONE_EXT` specifies that VkDeviceFaultAddressInfoEXT does not describe a page fault, or an instruction address.

- `VK_DEVICE_FAULT_ADDRESS_TYPE_READ_INVALID_EXT` specifies that VkDeviceFaultAddressInfoEXT describes a page fault triggered by an invalid read operation.

- `VK_DEVICE_FAULT_ADDRESS_TYPE_WRITE_INVALID_EXT` specifies that VkDeviceFaultAddressInfoEXT describes a page fault triggered by an invalid write operation.

- `VK_DEVICE_FAULT_ADDRESS_TYPE_EXECUTE_INVALID_EXT` describes a page fault triggered by an attempt to execute non-executable memory.

- `VK_DEVICE_FAULT_ADDRESS_TYPE_INSTRUCTION_POINTER_UNKNOWN_EXT` specifies an instruction pointer value at the time the fault occurred. This may or may not be related to a fault.

- `VK_DEVICE_FAULT_ADDRESS_TYPE_INSTRUCTION_POINTER_INVALID_EXT` specifies an instruction pointer value associated with an invalid instruction fault.

- `VK_DEVICE_FAULT_ADDRESS_TYPE_INSTRUCTION_POINTER_FAULT_EXT` specifies an instruction pointer value associated with a fault.

Note | The instruction pointer values recorded may not identify the specific instruction(s) that triggered the fault. The relationship between the instruction pointer reported and triggering instruction will be vendor-specific.
