* rtems: Add rtems_scheduler_get_processor_maximum()Sebastian Huber2019-04-093-4/+4
| | | | | | | | | | | Add rtems_scheduler_get_processor_maximum() as a replacement for rtems_get_processor_count(). The rtems_get_processor_count() is a bit orphaned. Adopt it by the Scheduler Manager. The count is also misleading, since the processor set may have gaps and the actual count of online processors may be less than the value returned by rtems_get_processor_count(). Update #3732.
* rtems: Add rtems_scheduler_get_processor()Sebastian Huber2019-04-091-1/+1
| | | | | | | | | | | Add rtems_scheduler_get_processor() as a replacement for rtems_get_current_processor(). The rtems_get_current_processor() is a bit orphaned. Adopt it by the Scheduler Manager. This is in line with the glibc sched_getcpu() function. Deprecate rtems_get_current_processor(). Update #3731.
* bsps: Adjust bsp.h Doxygen groupsSebastian Huber2019-03-082-8/+24
| | | | Update #3706.
* bsps: Adjust architecture Doxygen groupsSebastian Huber2019-03-041-1/+1
| | | | | | | | | | - Use CamelCase as it is not used in our C code. Enables simple search and replace. - Prefix with "RTEMS" to aid deployment and integration. It aids searching and sorting. Update #3706.
* grlib: Move header filesSebastian Huber2019-01-227-9/+9
| | | | Update #3678.
* Simplify _CPU_Counter_difference()Sebastian Huber2018-12-073-101/+63
| | | | | | | | | | | | | | In order to simplify the use of CPU counter values it is beneficial to have monotonic increasing values within the range of the CPU counter ticks data type, e.g. 32-bit unsigned integer. This eases the use of CPU counter timestamps in external tools which do not know the details of the CPU counter hardware. The CPU counter is the fastest way to get a time on an RTEMS system. Such a CPU counter may be also used as the timecounter. Use it on SPARC for this purpose to simplify the clock drivers. Update #3456.

* leon: do not use -mfix-{device} with ClangDaniel Hellstrom2018-10-092-2/+28
| | | | | | | | | Clang do not support -mfix-gr712rc, -mfix-ut700 and -mfix-ut699. Therefore we adjust the CPU_CFLAGS to remove these when compiling with Clang. Instead use GR712RC: -mcpu=gr712rc GR740: -mcpu=gr740 UT699/UT700: Not currently supported by clang, use LEON3 BSP.

* bsp/leon3: Fix typo which breaks the CPU counterSebastian Huber2018-09-201-1/+1
| | | | Update #3456.
* network: Use kernel/user space header filesSebastian Huber2018-09-103-3/+3
| | | | | | | | | | Add and use <machine/rtems-bsd-kernel-space.h> and <machine/rtems-bsd-user-space.h> similar to the libbsd to avoid command line defines and defines scattered throught the code base. Simplify cpukit/libnetworking/Makefile.am. Update #3375.
* bsps/sparc: Move polled APBUART functionsSebastian Huber2018-08-101-1/+0
| | | | This reduces the link-time dependencies and avoids copy-and-paste.
* _SMP_Start_multitasking_on_secondary_processor()Sebastian Huber2018-07-251-1/+1
| | | | | Pass current processor control as first parameter to make dependency more explicit.
* bsps: bsp_start_on_secondary_processor()Sebastian Huber2018-07-251-2/+3
| | | | | | Pass current processor control as first parameter in bsp_start_on_secondary_processor() and qoriq_start_thread() to make dependency more explicit.
* score: _SMP_Inter_processor_interrupt_handler()Sebastian Huber2018-07-251-1/+1
| | | | | Pass current processor control via parameter since it may be already available at the caller side.
* Remove Clock_driver_support_shutdown_hardware()Sebastian Huber2018-06-271-6/+0
| | | | | | | | | | | | | | | | | The aim of this clock driver hook was to stop clock tick interrupts at some late point in the exit() procedure. The use of atexit() pulls in malloc() which pulls in errno. It is incompatible with the intention of the CONFIGURE_DISABLE_NEWLIB_REENTRANCY configuration option. The exit() function must be called from thread context, so accompanied clock tick interrupts should cause no harm. On the contrary, someone may assume a normal operating system operation, e.g. working timeouts. Remove the Clock_driver_support_shutdown_hardware() clock driver hook. Close #3436.
* Add _CPU_Counter_frequency()Sebastian Huber2018-06-151-9/+13
| | | | | | | | | | 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.

* bsps: Rework cache manager implementationSebastian Huber2018-01-311-0/+191
| | | | | | | | | | | | | | | | | | The previous cache manager support used a single souce file (cache_manager.c) which included an implementation header (cache_.h). This required the use of specialized include paths to find the right header file. Change this to include a generic implementation header (cacheimpl.h) in specialized source files. Use the following directories and files: * bsps/shared/cache * bsps/@RTEMS_CPU@/shared/cache * bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILY/start/cache.c Update #3285.
* Remove make preinstallChris Johns2018-01-257-0/+1010
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.
