sl@0: // f32test\demandpaging\t_wdpstress.cpp
sl@0: // Data Paging Stress Tests
sl@0: // Common command lines:
sl@0: // t_wdpstress lowmem
sl@0: // debug - switch on debugging information
sl@0: // silent - no output to the screen or serial port
sl@0: // single - run the tests in a single thread
sl@0: // multiple <numThreads> - run the tests in multiple threads where <numThreads> (max 50 simultaneous threads)
sl@0: // interleave - force thread interleaving
sl@0: // prio - each thread reschedules in between each function call, causes lots of context changes
sl@0: // media - perform media access during the tests, very stressful
sl@0: // lowmem - low memory tests
sl@0: // stack - perform autotest only with stack paging tests
sl@0: // chunk - perform autotest only with chunk paging tests 			
sl@0: // commit - perform autotest only with committing and decommitting paging tests 
sl@0: // ipc - perform autotest only with ipc pinning tests 			
sl@0: // all - perform autotest with all paging tests(ipc, stack, chunk and commit)
sl@0: // badserver - perform ipc pinning tests with dead server
sl@0: // iters <count> - the number of times to loop 
sl@0: //
