* score: Add CPU_Exception_frameSebastian Huber2012-11-2744-6/+458
| | | | | | | | | | | | | | | | | | | | | Add CPU port type CPU_Exception_frame and function _CPU_Exception_frame_print(). The CPU ports of avr, bfin, h8300, lm32, m32c, m32r, m68k, nios2, sh, sparc64, and v850 use an empty default implementation of _CPU_Exception_frame_print(). Add rtems_exception_frame and rtems_exception_frame_print(). Add RTEMS_FATAL_SOURCE_EXCEPTION for CPU exceptions. Use rtems_fatal() with source RTEMS_FATAL_SOURCE_EXCEPTION in CPU ports of i386, powerpc, and sparc for unexpected exceptions. Add third parameter to RTEMS_BSP_CLEANUP_OPTIONS() which controls the BSP_PRINT_EXCEPTION_CONTEXT define used in the default bsp_fatal_extension(). Add test sptests/spfatal26.
* powerpc: Add CPU_Exception_frameSebastian Huber2012-11-271-0/+46
| | | | | The powerpc port uses now a unified CPU_Exception_frame. This resulted in a CPU_Exception_frame layout change for the MPC5XX.
* score: PR1607: Add and use CPU_SIZEOF_POINTERSebastian Huber2012-11-2220-4/+114
| | | | | | | | | | | | | | | | | Add and use new CPU port define CPU_SIZEOF_POINTER. It must be an integer literal that can be used by the assembler. This value will be used to calculate offsets of structure members. These offsets will be used in assembler code. The size of a pointer is part of the application binary interface (ABI) and thus independent of the actual programming language. The compiler will provide defines to determine the current ABI. We use these defines to select the appropriate CPU_SIZEOF_POINTER value. Static assertions in the new file "cpukit/score/src/percpuasm.c" will ensure that the value of CPU_SIZEOF_POINTER is consistent with the current compiler settings. Also the offset values used by assembler code are verfied.
* score: Inline _API_extensions_Run_postswitch()Sebastian Huber2012-11-223-21/+16
| | | | | The _API_extensions_Run_postswitch() function is only used in _Thread_Dispatch(). Avoid superfluous load of _Thread_Executing.
* score: Inline _User_extensions_Thread_switch()Sebastian Huber2012-11-223-44/+17
| | | | | The _User_extensions_Thread_switch() function is only used in _Thread_Dispatch().
* score: Add and use <rtems/score/userextimpl.h>Sebastian Huber2012-11-2228-223/+252
| | | | | This file contains the parts of <rtems/score/userext.h> that are only necessary for the RTEMS implementation.
* score: Avoid superfluous loadsSebastian Huber2012-11-221-4/+12
|
* score: Change _Internal_error_Occurred()Sebastian Huber2012-11-222-10/+24
| | | | | | | Call the fatal handlers of the user extensions before the update of _Internal_errors_What_happened. This reduces the requirements on the execution context further. Now a valid read-write data is only required after the call to the fatal handlers.
* score: Delete nest level from internal error stateSebastian Huber2012-11-222-9/+0
| | | | This reverts commit 7d0bdcac1ac20d6f22b24689c16e6aa7bc3c1e40.

|
* score: Add RTEMS_FATAL_SOURCE_POWERPC_EXCEPTIONSebastian Huber2012-11-211-0/+9
| | | | | | | | | Add ppc_exc_print_frame_and_context() which prints an exception frame and the context via printk(). The global exception handler will call now rtems_fatal() with source RTEMS_FATAL_SOURCE_POWERPC_EXCEPTION. The fatal code will contain the pointer value to the exception frame.
* score: Add and use _TOD_Get_with_nanoseconds()Sebastian Huber2012-11-215-89/+35

* score: Add RTEMS_FATAL_SOURCE_EXITSebastian Huber2012-11-151-0/+7
| | | | | | | Include <bsp/default-initial-extension.h> in all BSPs. Call rtems_fatal() with RTEMS_FATAL_SOURCE_EXIT as source and the exit() status code as fatal code in every bsp_cleanup(). Move previous bsp_cleanup() code into bsp_fatal_extension().

* score: Add RTEMS_FATAL_SOURCE_BDBUFSebastian Huber2012-11-151-0/+7
| | | | | | Add rtems_bdbuf_fatal_code as a replacement for the previous fatal error codes. Remove unused error codes. Add new error codes. Use rtems_fatal() with RTEMS_FATAL_SOURCE_BDBUF as source.
* score: Add RTEMS_FATAL_SOURCE_LASTSebastian Huber2012-11-151-2/+10
| | | | | This enum value ensures that the enum type needs at least 32-bits for architectures with short enums.
* score: Add INTERNAL_ERROR_CPU_ISR_INSTALL_VECTORSebastian Huber2012-11-153-1/+36
| | | | | Use INTERNAL_ERROR_CPU_ISR_INSTALL_VECTOR on PowerPC for _CPU_ISR_install_vector().
* score: Add nest level to interal error stateSebastian Huber2012-11-152-0/+9
| | | | | Add Internal_errors_Information::nest_level. This helps to detect recursive calls to _Internal_error_Occurred().

* powerpc: Delete _CPU_Install_interrupt_stack()Sebastian Huber2012-11-141-11/+0
| | | | This function is only used if CPU_HAS_HARDWARE_INTERRUPT_STACK == TRUE.
* score: Fix per CPU member offsetsSebastian Huber2012-11-131-65/+47
| | | | | | | | Offset calculation was wrong for 16-bit and 64-bit pointer targets. Remove unused offsets. Move Per_CPU_Control::dispatch_necessary after Per_CPU_Control::isr_nest_level. Move SMP members to end of structure. All assembler relevant members are now at the structure beginning.
* score: Move global variables definitionSebastian Huber2012-11-133-2/+6
| | | | | Define _System_state_Current and _Internal_errors_What_happened in interr.c to make _Internal_error_Occurred() more independent.
* score: Statically initialize user extensionsSebastian Huber2012-11-133-30/+52
| | | | | | | | | The initial extensions remain now in a read-only table and will not be copied to work space memory. The extension chains are statically initialized. This makes it possible to call _User_extensions_Iterate() independent of the system state. It is now guaranteed that the fatal callout of the initial extensions will be called provided the stack pointer, the read-only data, and code memory are valid.
* score: Add and use _User_extensions_Iterate()Sebastian Huber2012-11-138-283/+260
| | | | | | | Replace the separate user extension iterations with a single iteration function. This reduces code size and improves maintainability since the iteration logic is only in one function. The runtime overhead is insignificant.

* rtems: Add system eventsSebastian Huber2012-10-302-0/+18
| | | | | | | System events are similar to normal events. They offer a second set of events. These events are intended for internal RTEMS use and should not be used by applications (with the exception of the transient system event).
