* score: Add CPU_INTERRUPT_STACK_ALIGNMENTSebastian Huber2018-06-271-0/+2
| | | | | | | Add CPU port define for the interrupt stack alignment. The alignment should take the stack ABI and the cache line size into account. Update #3459.
* Add _CPU_Counter_frequency()Sebastian Huber2018-06-152-3/+4
| | | | | | | | | | Add rtems_counter_frequency() API function. Use it to initialize the counter value converter via the new system initialization step (RTEMS_SYSINIT_CPU_COUNTER). This decouples the counter implementation and the counter converter. It avoids an unnecessary pull in of the 64-bit integer division from libgcc. Update #3456.
* build: Remove DISTCLEANFILESSebastian Huber2018-04-091-1/+0
| | | | | A "make distclean" is not supported. So, it makes no sense to have pure "make distclean" related stuff in the Makefile.am.
* or1k/include/rtems/score/types.h: Eliminate this fileJoel Sherrill2018-03-123-55/+4
| | | | Updates #3327.
* Remove make preinstallChris Johns2018-01-2511-73/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A speciality of the RTEMS build system was the make preinstall step. It copied header files from arbitrary locations into the build tree. The header files were included via the -Bsome/build/tree/path GCC command line option. This has at least seven problems: * The make preinstall step itself needs time and disk space. * Errors in header files show up in the build tree copy. This makes it hard for editors to open the right file to fix the error. * There is no clear relationship between source and build tree header files. This makes an audit of the build process difficult. * The visibility of all header files in the build tree makes it difficult to enforce API barriers. For example it is discouraged to use BSP-specifics in the cpukit. * An introduction of a new build system is difficult. * Include paths specified by the -B option are system headers. This may suppress warnings. * The parallel build had sporadic failures on some hosts. This patch removes the make preinstall step. All installed header files are moved to dedicated include directories in the source tree. Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc, etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g. erc32, imx, qoriq, etc. The new cpukit include directories are: * cpukit/include * cpukit/score/cpu/@RTEMS_CPU@/include * cpukit/libnetworking The new BSP include directories are: * bsps/include * bsps/@RTEMS_CPU@/include * bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include There are build tree include directories for generated files. The include directory order favours the most general header file, e.g. it is not possible to override general header files via the include path order. The "bootstrap -p" option was removed. The new "bootstrap -H" option should be used to regenerate the "headers.am" files. Update #3254.

* score: Delete _CPU_Context_Fp_start()Sebastian Huber2017-01-261-11/+7
| | | | | | | | | | Since the FP area pointer is passed by reference in _CPU_Context_Initialize_fp() the optional FP area adjustment via _CPU_Context_Fp_start() is superfluous. It is also wrong with respect to memory management, e.g. pointer passed to _Workspace_Free() may be not the one returned by _Workspace_Allocate(). Close #1400.
* Remove CPU_BIG_ENDIAN and CPU_LITTLE_ENDIANSebastian Huber2017-01-241-2/+0
| | | | | | Use de-facto standard BYTE_ORDER instead. Close #2803.
* score: Robust thread dispatchSebastian Huber2016-11-231-0/+2
| | | | | | | | | | | | On SMP configurations, it is a fatal error to call blocking operating system with interrupts disabled, since this prevents delivery of inter-processor interrupts. This could lead to executing threads which are not allowed to execute resulting in undefined behaviour. The ARM Cortex-M port has a similar problem, since the interrupt state is not a part of the thread context. Update #2811.
* score: Add _ISR_Is_enabled()Sebastian Huber2016-11-181-0/+5
| | | | | | | In contrast to _ISR_Get_level() the _ISR_Is_enabled() function evaluates a level parameter and returns a boolean value. Update #2811.
* rtems: Conditionally define rtems_interrupt_frameSebastian Huber2016-11-181-1/+1
| | | | Update #2808.
* score: Move CPU_PER_CPU_CONTROL_SIZESebastian Huber2016-11-182-1/+4
| | | | | Move CPU_PER_CPU_CONTROL_SIZE and the optional CPU_Per_CPU_control to <rtems/score/cpuimpl.h> to hide it from <rtems.h>.
* score: Remove obsolete definesSebastian Huber2016-11-181-20/+0
| | | | The thread dispatch inline option is no longer used.
* score: Add <rtems/score/cpuimpl.h>Sebastian Huber2016-11-073-0/+35
| | | | | | The aim of this file is to encapsulate CPU port implementation details. This helps to hide implementation details from <rtems.h> which indirectly includes <rtems/score/cpu.h>.
* score: Fix C/C++ compatibility issueSebastian Huber2016-09-231-3/+0
| | | | | | | Only use CPU_Per_CPU_control if it contains at least one filed. In GNU C empty structures have a size of zero. In C++ structures have a non-zero size. In case CPU_PER_CPU_CONTROL_SIZE is defined to zero, then this structure is not used anymore.
* score: Simplify priority bit map implementationSebastian Huber2016-06-082-2/+0
| | | | | | | | | | The priority bit map can deal with a maximum of 256 priority values ranging from 0 to 255. Consistently use an unsigned int for computation, due to the usual integer promotion rules. Make Priority_bit_map_Word definition architecture-independent and define it to uint16_t. This was already the case for all architectures except PowerPC. Adjust the PowerPC bitmap support accordingly.
* score: Delete CPU_USE_GENERIC_BITFIELD_DATASebastian Huber2016-06-081-2/+0
| | | | | | 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: Delete dead copy and paste codeSebastian Huber2016-06-081-104/+1
|
* 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: Add CPU_MAXIMUM_PROCESSORSSebastian Huber2016-03-041-0/+2

* score: Introduce CPU_CACHE_LINE_BYTESSebastian Huber2016-01-261-21/+3
| | | | | 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.

* or1k fix bug: Initialize thread context with higher stack address.Hesham ALMatary2014-09-291-2/+3
| | | | | | Since or1k architecture stack grows down, threads should be initialized with high stack addresses instead of lower ones. This is done in _CPU_Context_Initialize function.
* score/cpu/or1k: Follow no_cpu ISR_Handler algorithm.Hesham ALMatary2014-09-161-0/+10
| | | | | | | | This patch adjusts ISR_Handler to exactly follow the pseudo code introduced in http://rtems.org/onlinedocs/doc-current/share/rtems/html/porting/Interrupts-Interrupt-Dispatching.html It adds two new checkings on _Thread_Dispatch_disable_level and _ISR_Nest_level after returning from the C handler.
* OpenRISC: Account for red-zone (fixup printf bug).Hesham ALMatary2014-09-162-19/+22
| | | | | | | | | | | | | | This patch allocate a space in the stack to account for red-zone that gcc may utilize for the use of leaf functions. Care must be taken to handle this red-zone from many places: 1- Upon creation of a new thread stack. 2- Once an interrupt entred. Also moving the enable-thread-dispach() and increment ISR level before checking if dispatch needed was required. The previous modifications solved the printf bug which disabled ticker to output strings after context switches that arise from Thread_Delay_ended.
* or1k: Let CPU/BSP Fatal handler have access to sourceHesham ALMatary2014-09-101-2/+2
| | | | | | This patchs follows the latest commit by Daniel Hellstrom that requires _CPU_Fatal_halt to have _source passed to it along with _error number.
