* score: Per-CPU thread dispatch disable levelSebastian Huber2013-08-092-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use a per-CPU thread dispatch disable level. So instead of one global thread dispatch disable level we have now one instance per processor. This is a major performance improvement for SMP. On non-SMP configurations this may simplifiy the interrupt entry/exit code. The giant lock is still present, but it is now decoupled from the thread dispatching in _Thread_Dispatch(), _Thread_Handler(), _Thread_Restart_self() and the interrupt entry/exit. Access to the giant lock is now available via _Giant_Acquire() and _Giant_Release(). The giant lock is still implicitly acquired via _Thread_Dispatch_decrement_disable_level(). The giant lock is only acquired for high-level operations in interrupt handlers (e.g. release of a semaphore, sending of an event). As a side-effect this change fixes the lost thread dispatch necessary indication bug in _Thread_Dispatch(). A per-CPU thread dispatch disable level greatly simplifies the SMP support for the interrupt entry/exit code since no spin locks have to be acquired in this area. It is only necessary to get the current processor index and use this to calculate the address of the own per-CPU control. This reduces the interrupt latency considerably. All elements for the interrupt entry/exit code are now part of the Per_CPU_Control structure: thread dispatch disable level, ISR nest level and thread dispatch necessary. Nothing else is required (except CPU port specific stuff like on SPARC).

* score: Use an ISR lock for TODSebastian Huber2013-08-011-7/+7
| | | | | | | | | | | | | Two issues are addressed. 1. On single processor configurations the set/get of the now/uptime timestamps is now consistently protected by ISR disable/enable sequences. Previously nested interrupts could observe partially written values since 64-bit writes are not atomic on 32-bit architectures in general. This could lead to non-monotonic uptime timestamps. 2. The TOD now/uptime maintanence is now independent of the giant lock. This is the first step to remove the giant lock in _Thread_Dispatch().
* score: Move nanoseconds since last tick supportSebastian Huber2013-08-012-20/+5
| | | | | | Move the nanoseconds since last tick support from the Watchdog to the TOD handler. Now the TOD managment is encapsulated in the TOD_Control structure.

* score: Add and use ISR locksSebastian Huber2013-07-311-48/+31
| | | | | | | | | | | | ISR locks are low-level locks to protect critical sections accessed by threads and interrupt service routines. On single processor configurations the ISR locks degrade to simple ISR disable/enable sequences. No additional storage or objects are required. This synchronization primitive is supported on SMP configurations. Here SMP locks are used.
