clock	sched/clock: Correct calculation for the case of Tickless mode with a 32-bit timer. In that case, the calculation was returning millisecond accuracy. That is not good when the timer accuracy is < 1 msec.	2016-11-19 09:55:21 -06:00

module	Without lowsyslog() *llinfo() is not useful. Eliminate and replace with *info().	2016-06-20 11:59:15 -06:00
mqueue	Correct a comment	2016-09-15 13:10:42 -06:00
paging	Without lowsyslog() *llinfo() is not useful. Eliminate and replace with *info().	2016-06-20 11:59:15 -06:00
pthread	Update TODO. Provide do-nothing stubs for mutex attribute interfaces if features not enabled. pthread_cond includes a signaling semaphore and should call sem_setprotocol.	2016-11-05 11:06:52 -06:00
sched	Update comments	2016-11-24 09:56:43 -06:00
semaphore	SMP: Add logic to avoid a deadlock condition when CPU1 is hung waiting for g_cpu_irqlock and CPU0 is waitin for g_cpu_paused	2016-11-22 11:34:16 -06:00
signal	This commit adds a new internal interfaces and fixes a problem with three APIs in the SMP configuration. The new internal interface is sched_cpu_pause(tcb). This function will pause a CPU if the task associated with 'tcb' is running on that CPU. This allows a different CPU to modify that OS data stuctures associated with the CPU. When the other CPU is resumed, those modifications can safely take place.	2016-11-20 07:57:18 -06:00

wdog	Most interrupt handling logic interacts with tasks via standard mechanism such as sem_post, sigqueue, mq_send, etc. This all call enter_critical_section and are assumed to be safe in the SMP case.	2016-11-18 13:57:30 -06:00
wqueue	Signal sent from work_signal() may interrupt the low priority worker thread that is already running. For example, the worker thread that is waiting for a semaphore could be woken up by the signal and break any synchronization assumption as a result. It also does not make any sense to send signal if it is already running and busy. This commit fixes it.	2016-11-06 08:00:12 -06:00
