EM supports notifying a subsystem when registered error occurs, using the register notifier API supported by XilPM. Use this command to register for notifications when registered errors occur. Refer to the xil_error_node.h file for a list of supported error event IDs and error masks for Versal devices.
- Node ID: Can either be a Device ID or Error Event ID. Use an Error Event ID for registering error events.
- Event Mask
- For Device ID: Event Type
- For Error Event ID: Error Mask
- Argument 1
- For Device ID: Wake
- Argument 2
- For Device ID: Enable
The register notifier for an event of an error event ID enables the error event by clearing the corresponding PMC/PSM_ERR#N_STATUS bit and writes to the corresponding PMC/PSM_IRQ#N_EN. The notifier returns an event index (which is a bit that notify callback sets) to indicate the occurrence of the event.
The register notifier command works with the notify callback command, for example, register notifier of error node GT_CR error event clears PMC_ERR1_STATUS.GT_CR, enables PMC_IRQ1_EN.GT_CR, and returns a number, for example, 5. Notify callback sets bit 5 of the event status to indicate that the GT_CR error has occurred.
