* sparc: Simplify trap table initializationSebastian Huber2021-06-242-7/+1
| | | | | | | | | | | | | | | Move _ISR_Handler() to a separate file since it is now only used if a handler is installed by _CPU_ISR_install_raw_handler(). Statically initialize the traps for external interrupts to use the new _SPARC_Interrupt_trap() which directly dispatches the interrupt handlers installed by rtems_interrupt_handler_install() via the BSP-provided _SPARC_Interrupt_dispatch(). Since the trap table is now fully statically initialized, there is no longer a dependency on the Cache Manager in the default configuration. Update #4458.
* bsps/sparc: Use rtems_interrupt_handler_install()Sebastian Huber2021-06-243-12/+28
| | | | | | | Avoid using set_vector() which depends on _ISR_Vector_table(). Prepare for a statically initialized trap table. Update #4458.
* sparc: More reliable bad trap handlingSebastian Huber2021-06-243-188/+0
| | | | | | | | | | | | | Statically initialize the trap table in start.S to jump to _SPARC_Bad_trap() for all unexpected traps. This enables a proper RTEMS fatal error handling right from the start. Do not rely on the stack and register settings which caused an unexpected trap. Use the ISR stack of the processor to do the fatal error handling. Save the full context which caused the trap. Fatal error handler may use it for error logging. Unify the _CPU_Exception_frame_print() implementations and move it to cpukit. Update #4459.
* bsps/irq: Remove BSP_INTERRUPT_VECTOR_MAXSebastian Huber2021-06-241-1/+0
| | | | | | This define is no longer used. Update #3269.
* bsps/irq: Add BSP_INTERRUPT_VECTOR_COUNTSebastian Huber2021-06-241-0/+1
| | | | | | | | | | | | | Assert BSP_INTERRUPT_VECTOR_MAX + 1 == BSP_INTERRUPT_VECTOR_COUNT. After building all BSPs with this patch, BSP_INTERRUPT_VECTOR_MAX can be removed and replaced by BSP_INTERRUPT_VECTOR_COUNT. The BSP_INTERRUPT_VECTOR_COUNT allows a default implementation which supports no interrupt vector at all. Using COUNT instead of MAX may avoid some interpretation issues, for example is the maximum value a valid vector number or not. Update #3269.
* bsps/irq: Remove BSP_INTERRUPT_VECTOR_MINSebastian Huber2021-06-241-1/+0
| | | | | | | | | | Remove BSP_INTERRUPT_VECTOR_MIN and unconditionally let interrupt vector numbers start with zero. The BSP_INTERRUPT_VECTOR_MIN == 0 invariant was tested by the previous commit and building all BSPs. Update #3269.

* 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.

* Simplify _CPU_Counter_difference()Sebastian Huber2018-12-071-40/+53
| | | | | | | | | | | | | | 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.
* bsp/leon2: Move printk() supportSebastian Huber2018-12-053-88/+31
| | | | | | | | | Avoid assert() in console_inbyte_nonblocking(). Do not poll forever in bsp_in_char(). This allows the caller to decide what to do if no character is available. This entangles some dependencies and fixes a spconfig02 test failure.
* network: Use kernel/user space header filesSebastian Huber2018-09-102-2/+2
| | | | | | | | | | 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.
* 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.

* bsps: Rework cache manager implementationSebastian Huber2018-01-311-0/+51
| | | | | | | | | | | | | | | | | | 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 Johns2018-01-256-0/+793
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.
