2022-09-19Do not use RTEMS_INLINE_ROUTINESebastian Huber1-32/+32
Directly use "static inline" which is available in C99 and later. This brings the RTEMS implementation closer to standard C. Close #3935.

2018-01-25Remove make preinstallChris Johns1-0/+0
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.

2014-03-11sapi: Use one SMP lock for all chainsSebastian Huber1-83/+39
This partially reverts commit 1215fd4d9426a59d568560e9a485628560363133. In order to support profiling of SMP locks and provide a future compatible SMP locks API it is necessary to add an SMP lock destroy function. Since the commit above adds an SMP lock to each chain control we would have to add a rtems_chain_destroy() function as well. This complicates the chain usage dramatically. Thus revert the patch above. A global SMP lock for all chains is used to implement the protected chain operations. Advantages: * The SAPI chain API is now identical on SMP and non-SMP configurations. * The size of the chain control is reduced and is then equal to the Score chains. * The protected chain operations work correctly on SMP. Disadvantage: * Applications using many different chains and the protected operations may notice lock contention. The chain control size drop is a huge benefit (SAPI chain controls are 66% larger than the Score chain controls). The only disadvantage is not really a problem since these applications can use specific interrupt locks and unprotected chain operations to avoid this issue.
2013-08-30sapi: SMP support for chainsSebastian Huber1-31/+134
Add ISR lock to chain control for proper SMP protection. Replace rtems_chain_extract() with rtems_chain_explicit_extract() and rtems_chain_insert() with rtems_chain_explicit_insert() on SMP configurations. Use rtems_chain_explicit_extract() and rtems_chain_explicit_insert() to provide SMP support.
