* 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.

* bsp/pc386: Disable interrupt nesting for job handlerJan Sommer2020-06-111-0/+10
| | | | | | | | | | | - Fixes timeout for smpipi01 where: + Main thread sends perform jobs to worker cpu while it is already performing jobs + Interrupt on worker cpu performs jobs, but with empty job list + Worker cpu continues to execut previous job and adds new job list to itself, which is never performed, since the interrupt has already been handled + Main thread blocks forever on barrier D
* bsps/pc386: Separate smp API functions. Makes smpfatal08 linkJan Sommer2020-06-115-55/+60

* bsps/pc386: Fix Clock_isr for SMPJan Sommer2020-06-111-1/+1
| | | | | | | | - Do not forward Clock_isr through Clock_driver_support_at_tick as this will cause every processor to send IPIs with Clock_isr therby creating an infinie loop - Instead the processor handling the clock interrupt causes all other processors to call rtems_timecounter_tick to update their tick count
* bsp/pc386: Define interrupt stack frame for smpJan Sommer2020-06-111-46/+56
| | | | | | - Defines CPU_Interrupt_frame in cpu_impl.h - Updates isq_asm.S to save/restore registers in matching order to interrupt frame
* bsp/pc386: Update GDT to work for SMPJan Sommer2020-06-115-41/+27
| | | | | | | | | | Create a GS segment in the GDT for each processor for storing TLS. This makes the GDT in startAP.S obsolete as all processors now share the same GDT, which is passed to each AP at startup. The correct segment for each processor is calculated in cpu_asm.S. Update #3335
* bsp/pc386: Turn start16.S into a startAP.SJan Sommer2020-06-113-256/+157
| | | | | | | | | | | start16.S is now only used for SMP configurations to start the application processors. This commit removes all unnecessary parts for this job, i.e. video conssole initalisation, A20 gate activation and all non-AP related code. Update #3335
* imfs: Replace devfs with an IMFS specializationSebastian Huber2020-03-091-2/+0
| | | | | | | | | | | | | | | | Add a simplified path evaluation function IMFS_eval_path_devfs() for a device only IMFS configuration. The code size can be further reduced by the application if it disables the support for legacy IO drivers via: #define CONFIGURE_IMFS_DISABLE_MKNOD #define CONFIGURE_IMFS_DISABLE_MKNOD_DEVICE Obsolete CONFIGURE_MAXIMUM_DEVICES. Remove BSP_MAXIMUM_DEVICES. Update #3894. Update #3898.

* bsps: Rework work area initializationSebastian Huber2020-02-041-11/+24
| | | | | | | | | | | | | | | | | | | | The work area initialization was done by the BSP through bsp_work_area_initialize(). This approach predated the system initialization through the system initialization linker set. The workspace and C program heap were unconditionally initialized. The aim is to support RTEMS application configurations which do not need the workspace and C program heap. In these configurations, the workspace and C prgram heap should not get initialized. Change all bsp_work_area_initialize() to implement _Memory_Get() instead. Move the dirty memory, sbrk(), per-CPU data, workspace, and malloc() heap initialization into separate system initialization steps. This makes it also easier to test the individual initialization steps. This change adds a dependency to _Heap_Extend() to all BSPs. This dependency will be removed in a follow up change. Update #3838.

* bsps: Support .rtemsstack.* linker input sectionsSebastian Huber2018-06-271-2/+3

* Remove Clock_driver_support_shutdown_hardware()Sebastian Huber2018-06-271-24/+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.
