DXGK_DSI_RESET structure (dispmprt.h)

  • Article

The DXGK_DSI_RESET structure is used with IOCTL_MIPI_DSI_RESET.

Syntax

typedef struct _DXGK_DSI_RESET {
  UINT  Flags;
  union {
    struct {
      UINT MipiErrors : 16;
      UINT ResetFailed : 1;
      UINT NeedModeSet : 1;
    };
    UINT Results;
  };
} DXGK_DSI_RESET, *PDXGK_DSI_RESET;

Members

Flags

Reserved. Must be set to zero.

MipiErrors

A combination of the DXGK_DSI_* values indicating the errors reported by communication with the peripheral. Can be one or more of the following values.

Error Meaning
DXGK_DSI_SOT_ERROR Possible error in Start of High-Speed transmission leader sequence

| DXGK_DSI_SOT_SYNC_ERROR | Error in Start of High-Speed transmission leader sequence |

| DXGK_DSI_EOT_SYNC_ERROR | Peripheral detected incomplete bytes in High-Speed transmission |

| DXGK_DSI_ESCAPE_MODE_ENTRY_COMMAND_ERROR | Error or peripheral does not recognize escape sequence |

| DXGK_DSI_LOW_POWER_TRANSMIT_SYNC_ERROR | Peripheral detected incomplete bytes in Low-Speed transmission |

| DXGK_DSI_FALSE_CONTROL_ERROR | Peripheral detected error in escape sequence or turnaround sequence |

| DXGK_DSI_CONTENTION_DETECTED | Contention detected |

| DXGK_DSI_CHECKSUM_ERROR_CORRECTED | A checksum error was detected and corrected |

| DXGK_DSI_CHECKSUM_ERROR_NOT_CORRECTED | A checksum error was detected but could not be corrected |

| DXGK_DSI_LONG_PACKET_PAYLOAD_CHECKSUM_ERROR | The payload checksum was incorrect for a long packet |

| DXGK_DSI_DSI_DATA_TYPE_NOT_RECOGNIZED | Peripheral does not recognize the data type sent to it |

| DXGK_DSI_DSI_VC_ID_INVALID | Peripheral was sent a command for a virtual channel which it does not support |

| DXGK_DSI_INVALID_TRANSMISSION_LENGTH | Peripheral detected that number of bytes transmitted does not match what was specified in the header |

| DXGK_DSI_DSI_PROTOCOL_VIOLATION | Peripheral detected lack of EoTP on a transmission or host failed to signal bus turn-around for a read |

ResetFailed

If set, the reset did not result in the panel returning to a working state.

NeedModeSet

If set on return from calling the graphics driver, the OS must perform an unoptimized mode set to the device in order to complete the reset.
