2018-04-23bsps: Move interrupt controller support to bspsSebastian Huber6-1452/+0
This patch is a part of the BSP source reorganization. Update #3285.
2018-01-25Remove make preinstallChris Johns3-266/+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.
2017-06-20bsps: Improve interrupt vector enable/disable APISebastian Huber1-8/+6
Change bsp_interrupt_vector_enable() and bsp_interrupt_vector_disable() to not return a status code. Add bsp_interrupt_assert() and use it to validate the vector number in the vector enable/disable implementations.

2016-10-17bsps/i386: replace global interrupt disable by SMP build supporting locking.Pavel Pisa3-22/+51
2016-10-11bsps/i386: Separate variable for i8259 IRQs disable due to in progress state.Pavel Pisa1-19/+36
The global state of enabled and disabled interrupts has to hold interrupts really disabled by drivers and system. If the state is combined with interrupts temporarily disabled because they are processed at given time then it is impossible to maintain state by interrupt handlers in drivers.

2016-05-11i386/pc386: Fix interrupt support.Chris Johns7-172/+469
Fix the interrupt and stop the spurious interrupt from happening. The fix moves the EOI to C code and cleans that functionality out of the asm part of the ISR handler. The code checks the ISR and IRR registers on the enable. Only ack the master for a slave IRQ if the slave has no other pending requests.
