core/hwtimer: add HWTIMER_WAIT_OVERHEAD
2014-10-01 19:53:43 +02:00

introduce HWTIMER_SPIN_BARRIER (API change)
...
Boards should define HWTIMER_SPIN_BARRIER that is used to decide
whether it makes sense to set a timer and yield or call hwtimer_spin
instead.
Used by `core/hwtimer.c` and `sys/vtimer/vtimer.c`.
A default value is provided and a warning is printed when it is used.

core/hwtimer: disable interrupts in hwtimer_remove
...
Before only the hardware timer's own interrupt was being disabled.
This led to a race condition in the following scenario:
```
Thread1:
hwtimer_remove()
hwtimer_arch_disable_interrupt();
// INTERRUPT -> Thread2 (which has a higher priority than Thread1) gets scheduled
Thread2:
...
hwtimer_remove()
hwtimer_arch_disable_interrupt(); // hwtimer interrupt is already disabled
...
hwtimer_arch_enable_interrupt();
...
// yield | terminate -> Thread1 gets scheduled again
Thread1:
... // these instructions are being run with the hwtimer interrupt enabled
hwtimer_arch_enable_interrupt(); // hwtimer interrupt is already enabled
```
Fixes #924
