Detailed Description

Tests timecounter installation related functions and directives of the Clock Manager.

This test case performs the following actions:

• Call the simple timecounter tick service with a zero delta and offset. This will lead to an overflow to zero of the timehand generation. It shall not change the initial clock values.
• Call the directives to get the initial value of CLOCK_REALTIME and the initial boot time.
  • Check the initial CLOCK_REALTIME in seconds and nanoseconds format.
  • Check that CLOCK_REALTIME is frozen in seconds and nanoseconds format.
  • Check the initial CLOCK_REALTIME in coarse resolution in seconds and nanoseconds format.
  • Check that CLOCK_REALTIME is frozen in coarse resolution in seconds and nanoseconds format.
  • Check the initial CLOCK_REALTIME in binary time format.
  • Check that CLOCK_REALTIME is frozen in binary time format.
  • Check the initial CLOCK_REALTIME in coarse resolution in binary time format.
  • Check that CLOCK_REALTIME is frozen in coarse resolution in binary time format.
  • Check the initial CLOCK_REALTIME in seconds and microseconds format.
  • Check that CLOCK_REALTIME is frozen in seconds and microseconds format.
  • Check the initial CLOCK_REALTIME in coarse resolution in seconds and microseconds format.
  • Check that CLOCK_REALTIME is frozen in coarse resolution in seconds and microseconds format.
  • Check the initial boot time in seconds and nanoseconds format.
  • Check the initial boot time in binary time format.
  • Check the initial boot time in seconds and microseconds format.
• Call the directives to get the initial value of CLOCK_MONOTONIC and the initial boot time.
  • Check the initial CLOCK_MONOTONIC in seconds and nanoseconds format.
  • Check that CLOCK_MONOTONIC is frozen in seconds and nanoseconds format.
  • Check the initial CLOCK_MONOTONIC in coarse resolution in seconds and nanoseconds format.
  • Check that CLOCK_MONOTONIC is frozen in coarse resolution in seconds and nanoseconds format.
  • Check the initial CLOCK_MONOTONIC in binary time format.
  • Check that CLOCK_MONOTONIC is frozen in binary time format.
  • Check the initial CLOCK_MONOTONIC in coarse resolution in binary time format.
  • Check that CLOCK_MONOTONIC is frozen in coarse resolution in binary time format.
  • Check the initial CLOCK_MONOTONIC in signed binary time format.
  • Check that CLOCK_MONOTONIC is frozen in signed binary time format.
  • Check the initial CLOCK_MONOTONIC in seconds and microseconds format.
  • Check that CLOCK_MONOTONIC is frozen in seconds and microseconds format.
  • Check the initial CLOCK_MONOTONIC in coarse resolution in seconds and microseconds format.
  • Check that CLOCK_MONOTONIC is frozen in coarse resolution in seconds and microseconds format.
• Install timecounter of different quality levels and frequencies.
  • Install a timecounter with a high quality level and normal frequency. Check that it was installed.
  • Install a timecounter with a high quality level and low frequency. Check that it was not installed.
  • Install a timecounter with a high quality level and high frequency. Check that it was installed.
  • Install a timecounter with a low quality level. Check that it was not installed.
• Call the directives to get the time in the highest resolution available to the system.
  • Check that the timecounter was used by rtems_clock_get_realtime().
  • Check that the timecounter was used by rtems_clock_get_realtime_bintime().
  • Check that the timecounter was used by rtems_clock_get_realtime_timeval().

  • Check that the timecounter was used by rtems_clock_get_monotonic_timeval().
• Call the directives to get the time in a coarse resolution.
  • Check that the timecounter was not used by rtems_clock_get_realtime_coarse().
