* bsps: Move startup files to bspsSebastian Huber2018-04-208-450/+0
| | | | | | | | Adjust build support files to new directory layout. This patch is a part of the BSP source reorganization. Update #3285.
* bsps: Convert all bsp_predriver_hook()Sebastian Huber2018-04-201-30/+0
| | | | | | Use RTEMS_SYSINIT_ITEM() instead. Update #2408.
* sparc/*/linkcmds*: Move ENTRY() from linkcmds.base to top linkcmdsJoel Sherrill2018-02-051-0/+2
| | | | | | | | This was at the request of a user to make it easier to have a custom entry point. This way they just provide their own top level linkcmds and include linkcmds.base. Updates #3520.
* Remove make preinstallChris Johns2018-01-251-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* sparc: Add lazy floating point switchSebastian Huber2017-07-251-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The SPARC ABI is a bit special with respect to the floating point context. The complete floating point context is volatile. Thus, from an ABI point of view nothing needs to be saved and restored during a context switch. Instead the floating point context must be saved and restored during interrupt processing. Historically, the deferred floating point switch was used for SPARC and the complete floating point context is saved and restored during a context switch to the new floating point unit owner. This is a bit dangerous since post-switch actions (e.g. signal handlers) and context switch extensions may silently corrupt the floating point context. The floating point unit is disabled for interrupt handlers. Thus, in case an interrupt handler uses the floating point unit then this will result in a trap (INTERNAL_ERROR_ILLEGAL_USE_OF_FLOATING_POINT_UNIT). In uniprocessor configurations, a lazy floating point context switch is used. In case an active floating point thread is interrupted (PSR[EF] == 1) and a thread dispatch is carried out, then this thread is registered as the floating point owner. When a floating point owner is present during a context switch, the floating point unit is disabled for the heir thread (PSR[EF] == 0). The floating point disabled trap checks that the use of the floating point unit is allowed and saves/restores the floating point context on demand. Update #3077.
* INTERNAL_ERROR_ILLEGAL_USE_OF_FLOATING_POINT_UNITSebastian Huber2017-07-251-0/+4
| | | | | | Add new fatal error INTERNAL_ERROR_ILLEGAL_USE_OF_FLOATING_POINT_UNIT. Update #3077.
* bsps/sparc: Fix warningsSebastian Huber2017-02-151-2/+7

* sparc: Optimize _ISR_Handler()Sebastian Huber2016-11-281-0/+3
| | | | | | Use _Thread_Do_dispatch() instead of _Thread_Dispatch(). Restore the PSR[EF] state of the interrupted context via new system call syscall_irqdis_fp in case floating-point support is enabled.
* bsps/sparc: Use default bsp_pretasking_hook()Sebastian Huber2015-12-101-0/+2
| | | | | | Move content to bsp_predriver_hook() functions of the BSPs. Update #2408.
* bsps/sparc: Fix trap table initializationSebastian Huber2014-12-051-4/+6

| | | | | Rename _BSP_Exception_frame_print() to _CPU_Exception_frame_print() to be in line with other CPU port functions.

* score: Add CPU_Exception_frameSebastian Huber2012-11-271-16/+21
| | | | | | | | | | | | | | | | | | | | | Add CPU port type CPU_Exception_frame and function _CPU_Exception_frame_print(). The CPU ports of avr, bfin, h8300, lm32, m32c, m32r, m68k, nios2, sh, sparc64, and v850 use an empty default implementation of _CPU_Exception_frame_print(). Add rtems_exception_frame and rtems_exception_frame_print(). Add RTEMS_FATAL_SOURCE_EXCEPTION for CPU exceptions. Use rtems_fatal() with source RTEMS_FATAL_SOURCE_EXCEPTION in CPU ports of i386, powerpc, and sparc for unexpected exceptions. Add third parameter to RTEMS_BSP_CLEANUP_OPTIONS() which controls the BSP_PRINT_EXCEPTION_CONTEXT define used in the default bsp_fatal_extension(). Add test sptests/spfatal26.
* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-117-14/+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.
* SPARC BSPs: implemented shared-irq using libbsp/shared layerDaniel Hellstrom2012-04-061-0/+25
| | | | | | | | | | | | | | | The implementation use IRQ number instead of vector number since some IRQs does not have a unique vector, for example the extended interrupts all enter the same trap vector entry. Added support for the LEON3 extended interrupt controller when using the shared IRQ layer. ERC32 patches untested. Signed-off-by: Daniel Hellstrom <daniel@gaisler.com> Regenerate
