The in-tree ice driver version 6.6.40-stx.2 does not provide the debugfs path used for monitoring the GNSS state. This commit provides the following changes to support this driver: 1: Update the k8s daemonset to mount the /sys/kernel/debug path instead of /sys/kernel/debug/ice. The "ice" directory is not present using the in-tree driver, so mounting the parent directory allows the containers to be properly started and can then check if the "ice" directory is present at runtime 2: Update the startup script for the v2 container to check for the existence of the ice debugfs directory. If it is not present, disable GNSS tracking in ptp-notification 3: Update the path used by GNSS monitoring to match the changed mount path in the daemonset so that GNSS monitoring can proceed when the path is present Currently, GNSS time sources and monitoring cannot be used with the in-tree driver. GNSS time sources require configuring the system to use the out-of-tree ice driver. Test plan: Pass: Verify helm chart and container build Pass: Verify ptp-notification deployment using the in-tree ice driver, ensure that GNSS tracking is automatically disabled when debugfs is not present Pass: Verify ptp-notification deployment using the out-of-tree ice driver, ensure that GNSS tracking is operational when debugfs is present Story: 2011056 Task: 50940 Signed-off-by: Cole Walker <cole.walker@windriver.com> Change-Id: I73859408cf5655b58ebe2a1a78f407496c3380dd
