35 // Description: |
|
|
36 // tests scheduler & threads & priorities |
|
|
37 // + create multiple threads with various priorities |
|
|
38 // + check highest priority running thread is always running |
|
|
39 // + check next highest runs when highest suspended |
|
|
40 // + check several threads of equal priority share time |
|
|
41 // (only !CYG_SCHED_UNIQUE_PRIORITIES) |
|
|
42 // + check other threads are starved |
|
|
43 // + check setting priority dynamically causes a thread to |
|
|
44 // become/stay current/non-current |
|
|
45 // Omissions: |
|
|
46 // check yield |
|
|
47 // check can set threads with min and max priority |
|
|
48 // Options: |
|
|
49 // CYG_SCHED_UNIQUE_PRIORITIES |
|
|
50 // CYGIMP_THREAD_PRIORITY |
|
|
51 // CYGNUM_KERNEL_SCHED_PRIORITIES |
