Yocto DriveOS Linux Boot KPI

To enable Boot KPI in Yocto build, navigate to the file $NV_WORKSPACE/drive-foundation/platform-config/hardware/nvidia/platform/t264/automotive/pct/drive_av/linux/common_profile.mk Change the line:

ENABLE_BOOT_KPI_ARGS := n

to

ENABLE_BOOT_KPI_ARGS := y

After making the change, redo the bind_partition and flashing steps for Yocto, and upon boot, the boot KPI logs can be found by executing the following command on the target:

cat /sys/kernel/tegra_bootloader/profiler

Note

We recommended flashing Yocto with prod_nsr PCT for more accurate boot KPI logs
