kernel: Timer behavioral testing Test and validate the behavior of a timer driver. Takes a number of absolute timer cycle samples of a periodic timer then calculates statistical mean, variance, stddev along with total drift over the entire test time. Ensures standard deviation and drift are within a given configurable bound. Signed-off-by: Tom Burdick <thomas.burdick@intel.com>

samples, tests: convert string-based twister lists to YAML lists Twister now supports using YAML lists for all fields that were written as space-separated lists. Used twister_to_list.py script. Some artifacts on string length are due to how ruamel dumps content. Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no>

tests: kernel: timer_behavior: Fix building on targets with small SRAM In the default configuration of the test, with 10000 timer samples, the `periodic_data` array is too big to fit in SRAM on many targets. Use lower counts of samples for those, depending on their SRAM size, leaving at least 8 kB for other variables, buffers, stacks etc. Exclude the test for targets with less than 16 kB.

tests/kernel/timer/timer_behavior: Add support for external tool This patch adds a way to simplify using an external tool to measure timer behaviour on Zephyr. It modifies the timer behaviour jitter_drift.c tests to toggle a GPIO pin (defined via a new DTS compatible, "test-kernel-timer-behavior-external") that can be connected to an external tool, such as a logic analyzer, to measure timer behaviour. This GPIO pin toggle is behind a new CONFIG_TIMER_EXTERNAL_TEST Kconfig. A new pytest test is added so that it can collect the statistics from the external tool and assert some measurements. To collect statistics from the external tool, one needs to provide a Python module which provides a `run(seconds, config)` method, that will perform the test and return the statistics. Check the README file for more information about this interface. Finally, this on twister, this new test is behind a new fixture, "gpio-timerout".

tests/kernel/timer/timer_behavior: Add support for Saleae Logic 2 This patch shows an example of how to use the timer behavior external tool testing, using the Saleae Logic 2 application. Also, some board overlays were added as examples. Finally, testcase.yaml updated with parameters for the Saleae sample. Signed-off-by: Ederson de Souza <ederson.desouza@intel.com>
