| | | | | | | This patch enables unlimited model in POSIX key manger and have a decent runtime on POSIX key searching, adding and deleting operations. Memory overhead is lower than current implementation when the size of key and key value becomes big.

| | | | | | | | | | Add context parameter to _Thread_Start_multitasking() and use this function in rtems_smp_secondary_cpu_initialize(). This avoids duplication of code. Fix missing floating point context initialization in rtems_smp_secondary_cpu_initialize(). Now performed via _Thread_Start_multitasking().

* score: Use an ISR lock for TODSebastian Huber2013-08-018-30/+90
| | | | | | | | | | | | | 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 Huber2013-08-0111-91/+82
| | | | | | 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 Huber2013-07-314-48/+177
| | | | | | | | | | | | 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.

* smp: Delete _ISR_Disable_on_this_core(), etc.Sebastian Huber2013-07-304-144/+33
| | | | | | | | | | | | | | | | | | | | Delete _ISR_Enable_on_this_core(), _ISR_Flash_on_this_core(), _ISR_SMP_Disable(), _ISR_SMP_Enable(), _ISR_SMP_Flash(). The ISR disable/enable interface has no parameter to pass a specific object. Thus it is only possible to implement a single global lock object with this interface. Using the ISR disable/enable as the giant lock on SMP configurations is not feasible. Potentially blocking resource obtain sequences protected by the thread dispatch disable level are subdivided into smaller ISR disabled critical sections. This works since on single processor configurations there is only one thread of execution that can block. On SMP this is different (image a mutex obtained concurrently by different threads on different processors). The thread dispatch disable level is currently used as the giant lock. There is not need to complicate things with this unused interface.
* smp: Delete _ISR_SMP_Initialize()Sebastian Huber2013-07-303-16/+0

* score: Critical section change in _Thread_DispatchSebastian Huber2013-07-301-2/+2
| | | | | | | | | | | | | | | | If we enter _Thread_Dispatch() then _Thread_Dispatch_disable_level must be zero. Single processor RTEMS assumes that stores of non-zero values to _Thread_Dispatch_disable_level are observed by interrupts as non-zero values. Move the _Thread_Dispatch_set_disable_level( 1 ) out of the first ISR disabled critical section. In case interrupts happen between the _Thread_Dispatch_set_disable_level( 1 ) and _ISR_Disable( level ) then the interrupt will observe a non-zero _Thread_Dispatch_disable_level and will not issue a _Thread_Dispatch() and we can enter the ISR disabled section directly after interrupt processing. This change leads to symmetry between the single processor and SMP configuration.
