Fixes two issues: 1. The CPU usage consumed by monitoring the kern.log file for changes in the NIC cgu status was found to be excessive. This change reverts that implementation and returns to a polling approach similar to what was already used for monitoring ptp4l and os clock statuses. This has been observed to bring main process in the notificationservice-base image down from ~60% CPU to ~8-10% CPU utilization. In the future, a preferrable implementation would be to work with device driver owners to provide support for udev events, removing the need to poll the status of devices. 2. User supplied holdover times for each service type were not being applied correctly. Updated daemon.py to set the holdover times in the service context. This also includes providing a user configurable "CONTROL_TIMEOUT" parameter to control the frequency of polling. This is a global value and affects the polling rate for all services. Test-plan: PASS: Build and install ptp-notification app and containers PASS: Observe reduced CPU usage and confirm that GNSS monitoring still works PASS: User supplied holdover times work correctly, along with polling rate Story: 2010056 Task: 46512 Task: 46513 Signed-off-by: Cole Walker <cole.walker@windriver.com> Change-Id: Ic0050cc09f5118e7f1c32aa13168084d6456437e |
