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.
