* score: Delete CPU_USE_GENERIC_BITFIELD_DATASebastian Huber2016-06-082-6/+4
| | | | | | Rename __log2table into _Bitfield_Leading_zeros since it acually returns the count of leading zeros of an 8-bit integer. The value for zero is a bit odd. Provide it unconditionally.
* score: Rename _ISR_Disable() and _ISR_Enable()Sebastian Huber2016-05-201-2/+2
| | | | | | | | | Rename _ISR_Disable() into _ISR_Local_disable(). Rename _ISR_Enable() into _ISR_Local_enable(). Remove _Debug_Is_owner_of_giant(). This is a preparation to remove the Giant lock. Update #2555.
* score: _Thread_Dispatch_increment_disable_level()Sebastian Huber2016-05-201-2/+2
| | | | | | | | | | Avoid _Thread_Dispatch_increment_disable_level() and _Thread_Dispatch_decrement_disable_level() and thus the Giant lock. This is a preparation to remove the Giant lock. Update #2555.
* score: Add CPU_MAXIMUM_PROCESSORSSebastian Huber2016-03-041-0/+2
| | | | Maximum number of processors of all systems supported by this CPU port.
* score: Introduce CPU_CACHE_LINE_BYTESSebastian Huber2016-01-261-1/+5
| | | | | Add CPU_CACHE_LINE_BYTES for the maximum cache line size in bytes. The actual processor may use no cache or a smaller cache line size.
* score: Delete obsolete CPU_TIMESTAMP_* definesSebastian Huber2016-01-251-2/+0
| | | | Update #2271.

|
* score: Simplify <rtems/system.h>Sebastian Huber2015-06-261-1/+1
| | | | | Drop the <rtems/score/percpu.h> include since this file exposes a lot of implementation details.

* Let CPU/BSP Fatal handler have access to sourceDaniel Hellstrom2014-09-103-3/+4
| | | | | | | | | Without the source the error code does not say that much. Let it be up to the CPU/BSP to determine the error code reported on fatal shutdown. This patch does not change the current behaviour, just adds the option to handle the source of the fatal halt.
* score: Statically initialize _ISR_Vector_tableSebastian Huber2014-04-293-27/+1
|
* score: Rename Priority_bit_map_ControlSebastian Huber2014-04-031-1/+1
| | | | Rename Priority_bit_map_Control in Priority_bit_map_Word.

|
* score: Rename _Internal_error_Occurred()Sebastian Huber2014-02-213-3/+3
| | | | Rename _Internal_error_Occurred() into _Terminate().
* score: Add CPU counter supportSebastian Huber2014-02-142-0/+13
| | | | | | | | | Add a CPU counter interface to allow access to a free-running counter. It is useful to measure short time intervals. This can be used for example to enable profiling of critical low-level functions. Add two busy wait functions rtems_counter_delay_ticks() and rtems_counter_delay_nanoseconds() implemented via the CPU counter.
* Add thread-local storage (TLS) supportSebastian Huber2014-02-042-2/+5
| | | | | Tested and implemented on ARM, m68k, PowerPC and SPARC. Other architectures need more work.

|
* score: Simplify <rtems/score/cpuatomic.h>WeiY2013-08-281-30/+6
| | | | Add proper license and copyright.
* score/cpu: Add CPU_Per_CPU_controlSebastian Huber2013-08-091-0/+6
| | | | Add CPU port specific per-CPU control.

* nios2: Set CPU_ISR_PASSES_FRAME_POINTER to FALSEJeffrey O. Hill2013-03-112-23/+3
| | | | | This reflects what is currently happening. Define CPU_Interrupt_frame type to void to prevent accidental usage.
* nios2: Add _Nios2_Count_leading_zeros()Jeffrey O. Hill2013-03-113-0/+75
| | | | | Add _Nios2_Count_trailing_zeros(). They are currently more efficient than the corresponding GCC builtins.

* RTEMS: Delete ChangeLog files.Gedare Bloom2013-03-081-259/+0
| | | | | | | | | This commit deletes all RTEMS ChangeLog files. These files have been abandoned since converting to git version control. The historical data may be recovered by checking out any commit before this one. Most of the contents of these ChangeLog files can also be found in the git log. Two external ChangeLog files, ChangeLog.slac and ChangeLog.zlib, remain.
* NIOS2: Fix register restore sequence in epilogueSebastian Huber2013-01-141-3/+3
| | | | | This fix is critical. The previous implementation leads to system corruption.

* score misc: Clean up Doxygen #13 (GCI 2012)Mathew Kallada2012-12-0210-6/+76
| | | | | | | This patch is a task from GCI 2012 which improves the Doxygen comments in the RTEMS source. http://www.google-melange.com/gci/task/view/google/gci2012/8013205
* score: Add CPU_Exception_frameSebastian Huber2012-11-273-0/+27
| | | | | | | | | | | | | | | | | | | | | 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.
* score: PR1607: Add and use CPU_SIZEOF_POINTERSebastian Huber2012-11-221-0/+2
| | | | | | | | | | | | | | | | | 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.
* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-1126-54/+0
| | | | | | | | | | | | Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.
