VIDEO_TDR_APPLICATION_BLOCKED
The VIDEO_TDR_APPLICATION_BLOCKED bug check has a value of 0x00000142. This indicates that an application has been blocked from accessing graphics hardware.
VIDEO_TDR_APPLICATION_BLOCKED Parameters
| Parameter | Description |
|---|---|
| 1 | Optional pointer to internal TDR recovery context (TDR_RECOVERY_CONTEXT). |
| 2 | The pointer into responsible device driver module (e.g owner tag). |
| 3 | The secondary driver specific bucketing key. |
| 4 | Id of the process being blocked from accessing the GPU. |
Diagnostic approach
Use !analyze -v together with Parameters 1 through 4 to identify the TDR recovery context, responsible display-driver module, bucketing key, and process that was blocked from GPU access. Secondary callback data tagged {270A33FD-3DA6-460D-BA89-3C1BAE21E39B} contains additional TDR evidence and can be enumerated with .enumtag.
Correlate that data with the display miniport version and the TDR event that caused the application to be blocked. The process ID alone does not prove that the application caused the graphics timeout; the recovery context and driver-side evidence determine which graphics path failed.
