| 38 // tests scheduler & threads & priorities | |
| 39 // + create multiple threads with various priorities | |
| 40 // + check highest priority running thread is always running | |
| 41 // + check next highest runs when highest suspended | |
| 42 // + check several threads of equal priority share time | |
| 43 // (only !CYG_SCHED_UNIQUE_PRIORITIES) | |
| 44 // + check other threads are starved | |
| 45 // + check setting priority dynamically causes a thread to | |
| 46 // become/stay current/non-current | |
| 47 // Omissions: | |
| 48 // check yield | |
| 49 // check can set threads with min and max priority | |
| 50 // Options: | |
| 51 // CYG_SCHED_UNIQUE_PRIORITIES | |
| 52 // CYGIMP_THREAD_PRIORITY | |
