6bd52bce06 Tickless OS: Correct a bug: logic to detect changes in head of timer list was wrong. 2014-08-10 13:12:18 -06:00
Gregory Nutt
e1769b22f1 Remove os_internal.h it has been replace by several new header files under sched/. There have been some sneak inclusion paths via os_internal.h, so expect a few compilation errors for some architectures 2014-08-08 18:39:28 -06:00

5ee57bda59 Some final tickless OS bugfixes. No longer EXPERIMENTAL. Update some comments 2014-08-07 19:11:22 -06:00
Gregory Nutt
c9661ad5a7 Change all time conversions. Yech. New timer units in microseconds breaks all existing logic that used milliseconds in the conversions. Something likely got broken doing this, probably because I confused a MSEC2TICK conversion with a TICK2MSEC conversion. Also, the tickless OS no appears fully functional and passes the OS test on the simulator with no errors 2014-08-07 18:00:38 -06:00

17ea50b45e Fix compler error in tickless code when round robin scheduling is enabled. Other cosmetic fixes to comments 2014-08-07 14:14:09 -06:00
Gregory Nutt
0aa7209765 Change CONFIG_MSEC_PER_TICK to CONFIG_USEC_PER_TICK. This gives more options for system timers in general, but more importantly, let's us realize higher resolution for the case of CONFIG_SCHED_TICKLESS=y -- of course, at the risk of some new interger overvflow problems 2014-08-07 13:42:47 -06:00

f0eb4235d1 Add a new option CONFIG_SCHED_TICKLESS to enable the tickless OS. This is a work in progress but should be relatively safe since the new features are only enabled by this option (Safer but not 100% safe since it does not protect from typos and other dumb errors). 2014-08-06 18:25:42 -06:00

19abe47a6f sem_wait: Use set_errno() and get_errno(). Direce access inside the OS may not be supported in the future. 2014-07-31 15:01:37 -06:00
