* doxygen: score: Add x86-64 CPU architecture groupAndreas Dachsberger2019-04-022-0/+24
| | | | Update #3706.
* Remove superfluous <rtems/system.h> includesSebastian Huber2019-03-141-1/+0
|
* Remove explicit file names from @fileSebastian Huber2019-02-282-2/+2
| | | | | | This makes the @file documentation independent of the actual file name. Update #3707.
* x86_64: Remove use of proc_ptrSebastian Huber2018-11-123-34/+1
| | | | Update #3585.
* x86_64: Remove duplicate _CPU_Thread_Idle_body()Sebastian Huber2018-11-121-5/+0
|
* build: Include header.am in cpukit/Makefile.amSebastian Huber2018-10-102-18/+8
| | | | | Include all cpukit/*/header.am files in cpukit/Makefile.am. This gets rid of all subtree Makefile.am and the sudirs hack.
* build: Merge score/cpu/*/Makefile.amSebastian Huber2018-10-101-11/+0
|
* build: Remove specialized CPPFLAGSSebastian Huber2018-10-091-1/+0
|
* score: Remove CPU_PROVIDES_IDLE_THREAD_BODYSebastian Huber2018-10-052-1/+1
| | | | | | | Remove the CPU_PROVIDES_IDLE_THREAD_BODY option to avoid unnecessary conditional compilation. Close #3539.
* bsps/x86_64: Add APIC timer based clock driverAmaan Cheval2018-08-131-0/+23
| | | | | | | | | The APIC timer is calibrated by running the i8254 PIT for a fraction of a second (determined by PIT_CALIBRATE_DIVIDER) and counting how many times the APIC counter has ticked. The calibration can be run multiple times (determined by APIC_TIMER_NUM_CALIBRATIONS) and averaged out. Updates #2898.
* bsps/x86_64: Add support for RTEMS interruptsAmaan Cheval2018-08-136-33/+250
| | | | Updates #2898.
* bsps/x86_64: Add paging support with 1GiB super pagesAmaan Cheval2018-08-131-0/+13
| | | | Updates #2898.
* bsps/x86_64: Reorganize header files and compile-optionsAmaan Cheval2018-08-137-22/+81
| | | | Updates #2898.
* score: Remove CPU_PARTITION_ALIGNMENTSebastian Huber2018-08-021-1/+0
| | | | | | | | | | | | | | Use the CPU_SIZEOF_POINTER alignment instead. The internal alignment requirement is defined by the use of Chain_Node (consisting of two pointers) to manage the free chain of partitions. It seems that previously the condition CPU_PARTITION_ALIGNMENT >= sizeof(Chain_Node) was true on all CPU ports. Now, we need an additional check. Update #3482.
* score: Add _CPU_Instruction_illegal()Sebastian Huber2018-07-231-0/+5
| | | | | | | | On some architectures/simulators it is difficult to provoke an exception with misaligned or illegal data loads. Use an illegal instruction instead. Update #3433.
* score: Add _CPU_Instruction_no_operation()Sebastian Huber2018-07-201-0/+5
| | | | | This helps to reduce the use of architecture-specific defines throughout the code base.
* score: Move context validation declarationsSebastian Huber2018-07-202-16/+12
| | | | | | | The context validation support functions _CPU_Context_validate() and _CPU_Context_volatile_clobber() are used only by one test program (spcontext01). Move the function declarations to the CPU port implementation header file.
* x86_64/console: Add NS16550 polled console driverAmaan Cheval2018-07-112-0/+17
| | | | | | This addition allows us to successfully run the sample hello.exe test. Updates #2898.
* bsp/x86_64: Minimal bootable BSPAmaan Cheval2018-07-1111-0/+893
Current state: - Basic context initialization and switching code. - Stubbed console (empty functions). - Mostly functional linker script (may need tweaks if we ever want to move away from the large code model (see: CPU_CFLAGS). - Fully functional boot, by using FreeBSD's bootloader to load RTEMS's ELF for UEFI-awareness. In short, the current state with this commit lets us boot, go through the system initialization functions, and then call user application's Init task too. Updates #2898.
