fd484c4de9 Add support for statically allocated watchdog timer structures 2014-08-22 08:46:34 -06:00
Gregory Nutt
ad9b3f8ab8 wdog.h does not contain any application interface, only internal OS interface. Further, it is non-standard. Move wdog.h from include/ to include/nuttx. For the same reason, move the description of the watchdog timer interfaces from the Users Guide to the Porting Guide. 2014-08-21 11:16:55 -06:00
Gregory Nutt
952d87587f If we run out of pre-allocated watchdog times, the logic will allocate additional timers from the heap. A reserve of pre-allocated watchdog timers is maintained so that there will always be timers available for interrupt handlers. 2014-08-21 08:44:29 -06:00

27c48a383e Don't do 64-bit calculations if accuracy not achievable; Fix compile error in high res RTC mode 2014-08-15 17:48:07 -06:00

eed1d6c619 When reading the system timer, don't read a struct timespec, convert it to a fake tick count, then back to a timespec. Remove CLOCK_ACTIVETIME.. it is non-standard, unused, and gets in the way of changes like this 2014-08-15 03:55:41 -06:00

6546fa39c7 Tickless Stuff: Back out the risky timer operations when the ready-to-run list is modified. That is unsafe. An ugly workaround is just to keep an interval timer going all of the time with a minimum duration equal to the timeslice interval. 2014-08-12 11:12:00 -06:00

686e5d7e3d Tickless: If using an ALARM, then really should report time of expiration 2014-08-12 10:00:32 -06:00

649ef76f71 Timers: In Tickless mode, need to stop the interval timer before inserted a new delay into the timer list. Otherwise, the time is incorrect on the first entry of the list 2014-08-11 08:25:25 -06:00

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
