Kernel Event Logger Sample
|
|
################################
|
|
|
|
Overview
|
|
********
|
|
|
|
A simple application that demonstrates use of kernel event
|
|
logger feature. Two threads (A and B) of the same priority
|
|
are created and main thread is configured to have low priority,
|
|
which reads the events from kernel event logger's buffer and
|
|
prints to the console. When thread 'A' gets scheduled it will
|
|
sleep for 1 second. Similarly when thread 'B' gets scheduled
|
|
it will sleep for 0.5 seconds. When both A and B are sleeping,
|
|
the main thread gets scheduled and retrieves the events captured
|
|
from kernel event logger's buffer and prints to the console.

Building and Running
|
|
********************
|
|
|
|
This project outputs to the console. It can be built and executed
|
|
on QEMU as follows:
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/subsys/logging/kernel_event_logger
|
|
:board: qemu_x86
|
|
:goals: run
|
|
:compact:
