35 // Description: Tests the Kernel Real Time Clock
36 // This test creates a thread, starts the scheduler and
37 // delays for a time of about 5 seconds. This test should
38 // be expected to run for about this length of time.
39 // Omissions:
40 // Doesn't test alarms attached to RTC.
41 // Assumptions:
42 // CYGVAR_KERNEL_COUNTERS_CLOCK must be set.
43 // Resolution of clock small compared with 5s.
44 // Overhead small compared with 5s.
45 // Options:
46 // CYGIMP_KERNEL_COUNTERS_SINGLE_LIST
47 // CYGIMP_KERNEL_COUNTERS_MULTI_LIST
48 // CYGVAR_KERNEL_COUNTERS_CLOCK
49 // CYGNUM_KERNEL_COUNTERS_MULTI_LIST_SIZE
