Hi @nipunjoy, can you help me understand how this change can fix the warm-reboot issue? What's the error without this fix?

[nipunjoy]

@bingwang-ms

Root cause is due to below failure in regular config flow. "SAI_QOS_MAP_ATTR_TYPE: SAI_QOS_MAP_TYPE_PFC_PRIORITY_TO_PRIORITY_GROUP" is not supported and the same is updated in config_db.json via qos_cfg.j2. On seeing this failure, orchagent is not cleaning its states and it fails in warm-reboot, thinking there are unfinished pending tasks. Please find the error logs from warm-reboot flow.

@nipunjoy Thanks for the reply. Adding new platform to pfc_to_pg_map_supported_asics list will generate a new QoS map PFC_TO_PG_MAP on the device, can you please confirm if that's supported?

[nipunjoy]

@bingwang-ms yes, it is supported.
