2018-10-10build: Include header.am in cpukit/Makefile.amSebastian Huber1-1/+0
Include all cpukit/*/header.am files in cpukit/Makefile.am. This gets rid of all subtree Makefile.am and the sudirs hack.
2018-10-10build: Merge score/cpu/*/Makefile.amSebastian Huber1-9/+0
2018-10-09build: Remove specialized CPPFLAGSSebastian Huber1-1/+0
2018-10-05score: Remove CPU_PROVIDES_IDLE_THREAD_BODYSebastian Huber1-0/+1
Remove the CPU_PROVIDES_IDLE_THREAD_BODY option to avoid unnecessary conditional compilation. Close #3539.
2018-06-15Add _CPU_Counter_frequency()Sebastian Huber1-0/+1
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.
2018-01-25Remove make preinstallChris Johns1-14/+1
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.
2016-11-07score: Add <rtems/score/cpuimpl.h>Sebastian Huber1-0/+1
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>.
2014-02-17score: Use atomic API for SMP lockSebastian Huber1-1/+0
Use a ticket lock implementation based on atomic operations. Delete CPU port specific SMP lock implementations.
2014-02-14score: Add CPU counter supportSebastian Huber1-0/+1
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.
2013-05-31smp: New SMP lock APISebastian Huber1-0/+1
Move the SMP lock implementation to the CPU port. An optimal SMP lock implementation is highly architecture dependent. For example the memory models may be fundamentally different. The new SMP lock API has a flaw. It does not provide the ability to use a local context for acquire and release pairs. Such a context is necessary to implement for example the Mellor-Crummey and Scott (MCS) locks. The SMP lock is currently used in _Thread_Disable_dispatch() and _Thread_Enable_dispatch() and makes them to a giant lock acquire and release. Since these functions do not pass state information via a local context there is currently no use case for such a feature.

2012-05-11Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill1-4/+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.
