WineQ圈9	eff07c040a	Update tasks.c (#26) ... Reopen this PR.	5 years ago
RichardBarry	5d28744feb	Improve documentation for the ulTaskNotifyValueClear() and xTaskCatchUpTicks() API functions. ... Move the prototype and documentation for xTaskCatchUpTicks() into the correct place in the task.h header file (in the public documentation from the private documentation). Rename the variable that holds the return value in xTaskCatchUpTicks() to more accurately represent its meaning.	5 years ago
WineQ圈9	180d0b8ee3	Update tasks.c (#24) ... An error on trace argument. In "xTaskPriorityDisinherit", the disinherit priority should be "pxTCB->uxBasePriority". And, in "vTaskPriorityDisinheritAfterTimeout", the disinherit priority should be "uxPriorityToUse", which might not be "pxTCB->uxBasePriority".	5 years ago
RichardBarry	e1b98f0b4b	This change prevents tickless idle mode potentially sleeping for an extra tick in the corer case that a tick interrupt occurred between the scheduler being suspended and the expected idle time being checked for a second time (within the idle task) - as described by the sequence below. Th change updates eTaskConfirmSleepModeStatus() to specifically check if a tick is pending, and if so, abort entering sleep mode. ... + The idle task decides to enter sleep mode on the following line. ``` if( xExpectedIdleTime >= configEXPECTED_IDLE_TIME_BEFORE_SLEEP ) ``` + The scheduler is suspended, preventing any context switches. [Potentially a tick interrupt could occur here. That could happen if other tasks executing consumed a lot of time since the above code line executed. If a tick interrupt occurs here the interrupt will be entered but the interrupt will not do anything other than increment xPendedTicks.] + The expected idle time is checked again. No context switches can occur now so the code will execute until the scheduler is unsuspended. Assuming configEXPECTED_IDLE_TIME_BEFORE_SLEEP is set to a sensible value, a tick interrupt won't occur for some time. + portSUPPRESS_TICKS_AND_SLEEP() is called. + The default implementation of the tickless function calls eTaskConfirmSleep() - which prior to this change does not return eAbortSleep even though xPendedTicks is not 0, and after this change does return eAbortSleep.	5 years ago
