  • Added task-based timers to the Timer Manager. This added three new directives:
    • rtems_timer_initiate_server
    • rtems_timer_server_fire_after
    • rtems_timer_server_fire_when

In the process of doing this, a number of cleanups were made.

  • src/timerserver.c, src/timerserverfireafter.c, src/timerserverfirewhen.c: New files.
  • include/timer/timer.h: Added new prototypes and supporting types.
  • inline/rtems/rtems/timer.h, macros/rtems/rtems/timer.h: Enhanced _Timer_Is_interval_class() to cover the class TIMER_INTERVAL_ON_TASK.
  • src/Makefile.am: Accounted for new files.
  • src/rtemstimer.c: Added initialization of _Timer_Server variable.
  • src/timercancel.c, src/timerreset.c: Account for addition of timer classes. Also corrected the headers.
  • src/timercreate.c, src/timerdelete.c, src/timerfireafter.c, src/timerfireafter.c, src/timerident.c: Corrected header.
  • Property mode set to 100644
