* sched: Minor change - remove unneeded header filesKevin O'Connor2017-01-141-2/+0
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* sched: Improve AVR optimization of reschedule_timer()Kevin O'Connor2016-10-191-7/+11
| | | | | | | | Tweak the AVR register pressure optimization in reschedule_timer() to optimize it further. This improves the performance of AVR timers when there are several pending timers. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* sched: Use 'unsigned int' instead of 'uint16_t' for shutdown reasonKevin O'Connor2016-06-141-2/+2
| | | | | | | Use 'unsigned int' instead of 'uint16_t' as is faster on some platforms. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* sched: Use uint_fast8_t for return type of timersKevin O'Connor2016-06-141-2/+2
| | | | | | | | Some architectures are faster passing regular integers than 8bit integers. Use uint_fast8_t so that the architecture chooses the appropriate type. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* irq: Allow boards to define the return type of irq_save()Kevin O'Connor2016-06-131-3/+3
| | | | | | | | The AVR wants a uint8_t return type for irq_save(), but other architectures will generally prefer int. Allow the board to configure the size of the flag by introducing an irqstatus_t typedef. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* generic: Move board timer.h files into generic/misc.hKevin O'Connor2016-06-131-1/+1

* sched: Optimize timer list handlingKevin O'Connor2016-06-131-39/+50
| | | | | | Rework the timer list rescheduling to be more optimized. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* sched: Change sched_from_ms() to sched_from_us()Kevin O'Connor2016-06-021-6/+6
| | | | | | | Some code may require micro-second precision so update sched_from_ms() to use micro-seconds. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
