[PATCH 11/13] habanalabs/gaudi2: capture RAZWI information

Oded Gabbay
2022-10-06T08:24:13Z

From: Dani Liberman <dliberman@habana.ai>

Added function to calculate possible engines which caused
RAZWI (read-only zero, write ignored), from a given router id or
module index.

When getting RAZWI via PSOC IP, first the router id is calculated
and then the possible engines that caused the RAZWI are calculated.

There is a possibility that the RAZWI initiator is not an engine. In
that case, it will not be included in possible engines as it
doesn't have an engine id.

RAZWI information is captured when receiving event from engine or via
PSOC IP.
