* 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 Huber2016-11-071-0/+30
| | | | | | 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: Add CPU_MAXIMUM_PROCESSORSSebastian Huber2016-03-041-0/+2
| | | | Maximum number of processors of all systems supported by this CPU port.
* or1k: Delete superfluous _CPU_Null_fp_contextSebastian Huber2016-02-171-17/+1
| | | | Update #2559.
* 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.
* score: Delete obsolete CPU_TIMESTAMP_* definesSebastian Huber2016-01-251-4/+0
| | | | Update #2271.
* basedefs.h: Add and use RTEMS_NO_RETURNSebastian Huber2015-10-261-1/+1

* score/cpu/or1k: Add cpuatomic.h to fix broken build.Hesham ALMatary2015-03-041-0/+14
| | | | | 4e3d9a4d6c76fba8e31138d503f736405dafc213 broke or1k, cpuatomic.h has to be added to all architectures.
* 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.
* Add or1k tick timer register definitionsHesham ALMatary2014-08-181-2/+14
|
* Add support for OpenRISC - Fixed issuesHesham ALMatary2014-08-126-0/+1695
This work is based on the old or32 port (that has been removed back in 2005) authored by Chris Ziomkowski. The patch includes the basic functions every port should implement like: context switch, exception handling, OpenRISC ABI and machine definitions and configurations.
