H A D | ibm_vpd_app.cpp | 32c687f5 Tue Jan 04 23:14:03 CST 2022 Priyanga Ramasamy <priyanga24@in.ibm.com> Move json symlink before populating dbus interfaces
This commit reorders the flow of ibm-read-vpd app execution by first allowing the app to create symbolink link to the respective json and then populate dbus interfaces by having the right json.
Without this change, only those motherboard subfrus which are present in the default inventory json will gets its interfaces populated during genesis boot. Thus leaving machine specific motherboard's subfru's (powersupply, pcieslots, etc.,) dbus interfaces unpopulated.
With this change, all of the motherboard subfrus which are present in the symlink json will get its interfaces populated on dbus during genesis boot.
Test: Tested on simics rainier2s2u. Able to see all of the interfaces of motherboard's subfrus after the genesis boot.
