* 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 Huber2016-01-261-24/+4
| | | | | 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.
* basedefs.h: Add and use RTEMS_NO_RETURNSebastian Huber2015-10-261-2/+2

* Let CPU/BSP Fatal handler have access to sourceDaniel Hellstrom2014-09-101-1/+1
| | | | | | | | | 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: Rename Priority_bit_map_ControlSebastian Huber2014-04-031-1/+1
| | | | Rename Priority_bit_map_Control in Priority_bit_map_Word.
* Change all references of rtems.com to rtems.org.Chris Johns2014-03-211-1/+1

* score: Add CPU counter supportSebastian Huber2014-02-141-0/+12
| | | | | | | | | 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 Huber2014-02-041-1/+3
| | | | | Tested and implemented on ARM, m68k, PowerPC and SPARC. Other architectures need more work.
* score/cpu: Add CPU_Per_CPU_controlSebastian Huber2013-08-091-0/+6
| | | | Add CPU port specific per-CPU control.
* score: Add CPU context validationSebastian Huber2013-05-101-0/+12
|
* cpukit: Use Consistent Beginning of Doxygen Group NotationJoel Sherrill2013-01-101-4/+4
| | | | | This is the result of a sed script which converts all uses of @{ into a consistent form.
* score: Doxygen Clean Up Task #5Alex Ivanov2013-01-021-585/+609

* score: Add CPU_Exception_frameSebastian Huber2012-11-271-0/+5
| | | | | | | | | | | | | | | | | | | | | 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/+6
| | | | | | | | | | | | | | | | | 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 Sherrill2012-05-111-2/+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.

| | | | | | * rtems/score/cpu.h: Add RTEMS_COMPILER_NO_RETURN_ATTRIBUTE to _CPU_Context_restore() because it does not return. Telling GCC this avoids generation of dead code.
* 2010-07-29 Gedare Bloom <giddyup44@yahoo.com>Joel Sherrill2010-07-291-1/+1
| | | | | | | | | | | PR 1635/cpukit * rtems/score/cpu.h, rtems/score/types.h: Refactoring of priority handling, to isolate the bitmap implementation of priorities in the supercore so that priority management is a little more modular. This change is in anticipation of scheduler implementations that can select how they manage tracking priority levels / finding the highest priority ready task. Note that most of the changes here are simple renaming, to clarify the use of the bitmap-based priority management.
