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 |
