This test should // be expected to run for about this length of time. // Omissions: // Doesn't test alarms attached to RTC. // Assumptions: // CYGVAR_KERNEL_COUNTERS_CLOCK must be set. // Resolution of clock small compared with 5s. // Overhead small compared with 5s. // Options: // CYGIMP_KERNEL_COUNTERS_SINGLE_LIST // CYGIMP_KERNEL_COUNTERS_MULTI_LIST // CYGVAR_KERNEL_COUNTERS_CLOCK // CYGNUM_KERNEL_COUNTERS_MULTI_LIST_SIZE //####DESCRIPTIONEND#### #include <pkgconf/kernel.h> #include <cyg/kernel/clock.hxx> #include <cyg/kernel/thread.hxx> #include <cyg/infra/testcase.h> #include <cyg/kernel/clock.inl> #include <cyg/kernel/thread.inl> #ifdef CYGVAR_KERNEL_COUNTERS_CLOCK #define NTHREADS 1 #include "testaux.hxx" static cyg_uint32 ticks; // Number of ticks thread[0] will delay for static cyg_uint64 TEST_DELAY; static void entry0( CYG_ADDRWORD data ) { ((Cyg_Thread *)data)->delay(ticks); CYG_TEST_PASS_FINISH("Clock 1 OK"); } void clock1_main( void ) { CYG_TEST_INIT(); if (cyg_test_is_simulator) { TEST_DELAY = 100000000ll; } else { TEST_DELAY = 3000000000ll; } new_thread(entry0, (CYG_ADDRWORD)&thread_obj[0]); Cyg_Clock::cyg_resolution res; res = Cyg_Clock::real_time_clock->get_resolution (); // RTC takes res.dividend/res.divisor ns/tick ticks = ((cyg_uint64)TEST_DELAY * res.divisor) / res.dividend; Cyg_Scheduler::start(); } externC void cyg_start( void ) { #ifdef CYGSEM_HAL_STOP_CONSTRUCTORS_ON_FLAG cyg_hal_invoke_constructors(); #endif clock1_main(); } #else // def CYGVAR_KERNEL_COUNTERS_CLOCK externC void cyg_start( void ) { CYG_TEST_INIT(); CYG_TEST_NA( "Kernel real-time clock disabled"); } #endif // def CYGVAR_KERNEL_COUNTERS_CLOCK // EOF clock1.cxx
