* rtems: Add RTEMS_INTERRUPT_REPLACESebastian Huber2014-03-061-27/+54
| | | | | | | | | | | | | | | | | | | | | A new option RTEMS_INTERRUPT_REPLACE is introduced that permits updating the first interrupt handler for the registered interrupt vector and matching argument. If no match is found, the install function fails with RTEMS_UNSATISFIED. The Interrupt Manager Extension offers interrupt handlers with an argument pointer. It is impossible to update two words (handler and argument) atomically on most architectures. In order to avoid an SMP lock in bsp_interrupt_handler_dispatch() which would degrade the interrupt response time an alternative must be provided that makes it possible to tear-down interrupt sources without an SMP lock. Add RTEMS_INTERRUPT_REPLACE option to Interrupt Manager Extension. This enables a clean tear-down of interrupt sources on SMP configurations. Instead of an interrupt handler removal a replacement handler can be installed to silence an interrupt source. This can be used in contexts that allow no sophisticated synchronization (e.g. in atexit() or fatal handlers).

* bsps: Fix empty interrupt handler entrySebastian Huber2014-02-281-4/+5
| | | | | The vector number of spurious interrupts was wrong after the interrupt handler removal on SMP configurations.
* score: Add RTEMS_FATAL_SOURCE_BSPSebastian Huber2014-02-191-2/+2
| | | | | | Merge RTEMS_FATAL_SOURCE_BSP_GENERIC and RTEMS_FATAL_SOURCE_BSP_SPECIFIC into new fatal source RTEMS_FATAL_SOURCE_BSP. This makes it easier to figure out the code position given a fatal source and code.

* bsps: Use allocator mutex for generic IRQ supportSebastian Huber2012-11-061-89/+16
| | | | | | Since the allocator mutex allows nesting now we can use it for the generic IRQ support (recursive obtain in a potential malloc()). This simplifies the code and reduces memory usage.
