bernard 7a7e3002c8 [Kernel] system does not lock scheduler when invoking soft-timer timeout function. 2014-07-12 15:59:45 +08:00
Grissiom 6d9e793388 kernel: timer: fix compiling bug in d59aa279c3 2013-10-19 21:07:14 +08:00
Grissiom d59aa279c3 kernel: use skip list to implement timer list 
Skip list is a "random" data structure that in high possibilities it
would get O(log(N)) time complexity in inserting while the old list get
O(N). Forthermore, when set RT_TIMER_SKIP_LIST_LEVEL to 1, it will just
the same as the old double linked list, both in time and space
complexity.

Benchmarks shows that when RT_TIMER_SKIP_LIST_LEVEL is 3, the average
time of random insertion of new timer is about 2 times faster than the
old timer when there are 100 timers and 3 times faster when there are
200 timers.

However, it restores the deprecated funcion rt_system_timer_init. BSPs
must invoke it upon system startup.

Grissiom 0001344105 more deterministic on timer 
If two timer will timeout at the same tick, the one started later will
be called later. I've tested the patch on simulator and it _seems_ OK.
