... because it is (required). This makes a difference when building with CMake and forgetting ZEPHYR_BASE or not registering Zephyr in the CMake package registry. In this particular case, REQUIRED turns this harmless looking log statement: -- Could NOT find Zephyr (missing: Zephyr_DIR) -- The C compiler identification is GNU 9.3.0 -- The CXX compiler identification is GNU 9.3.0 -- Check for working C compiler: /usr/bin/cc -- ... -- ... -- ... -- Detecting CXX compile features -- Detecting CXX compile features - done CMake Error at CMakeLists.txt:8 (target_sources): Cannot specify sources for target "app" which is not built by this project. ... into this louder, clearer, faster and (last but not least) final error: CMake Error at CMakeLists.txt:5 (find_package): Could not find a package configuration file provided by "Zephyr" with any of the following names: ZephyrConfig.cmake zephyr-config.cmake Add the installation prefix of "Zephyr" to CMAKE_PREFIX_PATH or set "Zephyr_DIR" to a directory containing one of the above files. If "Zephyr" provides a separate development package or SDK, be sure it has been installed. -- Configuring incomplete, errors occurred! Signed-off-by: Marc Herbert <marc.herbert@intel.com> |

Title: Timer Starvation test The purpose of the test is to detect whether the timer implementation correctly handles situations where only one timeout is present, and that timeout is repeatedly rescheduled before it has a chance to fire. In some implementations this may prevent the timer interrupt handler from ever being invoked, which in turn prevents an announcement of ticks. Lack of tick announcement propagates into a monotonic increase in the value returned by z_clock_elapsed(). This test is not run in automatic test suites because it generally takes minutes, hours, or days to fail, depending on the hardware clock rate and the tick rate. By default the test passes if one hour passes without detecting a failure. Failure will occur when some counter wraps around. This may be a hardware timer counter, a timer driver internal calculation of unannounced cycles, or the Zephyr measurement of unannounced ticks. For example a system that uses a 32768-Hz internal timer counter with 24-bit resolution and determines elapsed time by a 24-bit unsigned difference between the current and last-recorded counter value will fail at 512 s when the updated counter value is observed to be less than the last recorded counter. Systems that use a 32-bit counter of 80 MHz ticks would fail after 53.687 s.
