DXGK_TDR_TYPE enumeration (d3dkmddi.h)

  • Artikel

The DXGK_TDR_TYPE enumeration specifies the type of timeout detection and recovery (TDR) event that occurred.

Syntax

typedef enum _DXGK_TDR_TYPE {
  DXGK_TDR_TYPE_UNKNOWN = 0,
  DXGK_TDR_TYPE_FORCED = 1,
  DXGK_TDR_TYPE_PREEMPT_TIMEOUT = 2,
  DXGK_TDR_TYPE_VSYNC_TIMEOUT = 3,
  DXGK_TDR_TYPE_DOD_PRESENT_FORCED = 4,
  DXGK_TDR_TYPE_DOD_PRESENT_TIMEOUT = 5,
  DXGK_TDR_TYPE_ENGINE_TIMEOUT = 6,
  DXGK_TDR_TYPE_DOD_VSYNC_FORCED = 7,
  DXGK_TDR_TYPE_DOD_VSYNC_TIMEOUT = 8,
  DXGK_TDR_TYPE_ENGINE_TIMEOUT_PROMOTED = 9,
  DXGK_TDR_TYPE_PAGE_FAULT = 10,
  DXGK_TDR_TYPE_INVALID_FENCE = 11,
  DXGK_TDR_TYPE_ENGINE_PAGE_FAULT = 12,
  DXGK_TDR_TYPE_DISPLAY_ENGINE_FAULT = 13
} DXGK_TDR_TYPE;

Constants

 
DXGK_TDR_TYPE_UNKNOWN
Value: 0
Reserved. A KMD's DxgkDdiCollectDbgInfo2 implementation shouldn't receive this value.
DXGK_TDR_TYPE_FORCED
Value: 1
The TDR is forced via D3DKMT_ESCAPE_TDRDBGCTRL with zero data or with D3DKMT_TDRDBGCTRLTYPE_FORCETDR type.
DXGK_TDR_TYPE_PREEMPT_TIMEOUT
Value: 2
For drivers that don't support engine reset, this value is used prior to resetting the whole adapter that had one of the GPU engines time out.
DXGK_TDR_TYPE_VSYNC_TIMEOUT
Value: 3
This value is used when the display part of the GPU doesn't acknowledge a pending flip request in a timely manner.
DXGK_TDR_TYPE_DOD_PRESENT_FORCED
Value: 4
This value is used for Display Only adapters when the TDR is forced via D3DKMT_TDRDBGCTRLTYPE_FORCEDODTDR escape.
DXGK_TDR_TYPE_DOD_PRESENT_TIMEOUT
Value: 5
This value is used for Display Only adapters when they don't complete a present within the TDR timeout.
DXGK_TDR_TYPE_ENGINE_TIMEOUT
Value: 6
This value is used when a particular GPU engine can't complete pending GPU work or a preemption request within the TDR timeout.
DXGK_TDR_TYPE_DOD_VSYNC_FORCED
Value: 7
This value is used for Display Only adapters when the TDR is forced via D3DKMT_TDRDBGCTRLTYPE_FORCEDODVSYNCTDR escape.
DXGK_TDR_TYPE_DOD_VSYNC_TIMEOUT
Value: 8
This value is used for Display Only adapters when they don't raise a VSync interrupt within the TDR timeout.
DXGK_TDR_TYPE_ENGINE_TIMEOUT_PROMOTED
Value: 9
This value is used when a GPU engine timeout is promoted by the OS to the full adapter reset.
DXGK_TDR_TYPE_PAGE_FAULT
Value: 10
This value is used when an adapter reset is requested by a GPU page fault interrupt that set the DXGK_PAGE_FAULT_ADAPTER_RESET_REQUIRED flag to 1.
DXGK_TDR_TYPE_INVALID_FENCE
Value: 11
This value is used for certain legacy pre-WDDM 2.4 drivers when the GPU reports an incorrect submission or preempted fence value that results in a GPU reset.
DXGK_TDR_TYPE_ENGINE_PAGE_FAULT
Value: 12
This value is used when a GPU engine reset is requested by a GPU page fault interrupt that set the DXGK_PAGE_FAULT_ENGINE_RESET_REQUIRED flag to 1.
DXGK_TDR_TYPE_DISPLAY_ENGINE_FAULT
Value: 13
This value is used when a display engine fault is detected by the OS.
