From 0606add0177e0f7880c5cf7e09c2e0442320a4b5 Mon Sep 17 00:00:00 2001 From: Maxime Lorrillere Date: Mon, 25 Apr 2022 13:09:42 -0700 Subject: [PATCH] [chassis] Get asic PCI ID from CHASSIS_STATE_DB and update asic_id in CONFIG_DB (#9681) Asic PCI ID (PCI address) is collected by chassisd (inside pmon - Azure/sonic-platform-daemons#175) and saved in CHASSIS_STATE_DB (in redis_chassis). CHASSIS_STATE_DB is accessible by swss containers. At docker-init.sh (script is called after swss container is created and before anything that could run in swss like orchagent...), we wait until asic PCI ID of the corresponding asic is populated by chassisd. We then update asic_id in CONFIG_DB of asic's database. A system supporting dynamic asic PCI ID identification requires to have a file (empty) use_pci_id_chassis in its platform dir. When orchagent runs, it has correct asic PCI ID in its CONFIG_DB.
