* m68k/uC5282: linkcmds KEEP and SORT sectionsGedare Bloom2021-07-011-15/+19
| | | | | Fixes a problem with bad epilog code in _fini and to keep sections necessary with the -ffunction/data-sections.
* bsps/irq: Remove BSP_INTERRUPT_VECTOR_MAXSebastian Huber2021-06-241-1/+0
| | | | | | This define is no longer used. Update #3269.
* bsps/irq: Use BSP_INTERRUPT_VECTOR_COUNTSebastian Huber2021-06-242-2/+2
| | | | | | Use BSP_INTERRUPT_VECTOR_COUNT instead of BSP_INTERRUPT_VECTOR_MAX. 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 Huber2021-06-241-2/+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/genmcf548x: Change BSP_INTERRUPT_VECTOR_MINSebastian Huber2021-06-241-1/+9
| | | | | | | | | This BSP uses a customized implementation of the interrupt extension API. It was the only BSP which defined BSP_INTERRUPT_VECTOR_MIN to a value other than zero. Define it to zero and use a custom bsp_interrupt_is_valid_vector() function instead. Update #3269.
* bsps: Support RTEMS_NOINIT in linkcmdsSebastian Huber2021-05-0220-0/+82
| | | | Update #3866.

* bsps: Replace bsp_specs with an empty fileSebastian Huber2021-01-2816-152/+0
| | | | | | | This fixes an issue with the latest tool chain which adds the default linker script in the endfile specification. Update #3250.

* Rework initialization and interrupt stack supportSebastian Huber2018-06-2721-118/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Statically initialize the interrupt stack area (_Configuration_Interrupt_stack_area_begin, _Configuration_Interrupt_stack_area_end, and _Configuration_Interrupt_stack_size) via <rtems/confdefs.h>. Place the interrupt stack area in a special section ".rtemsstack.interrupt". Let BSPs define the optimal placement of this section in their linker command files (e.g. in a fast on-chip memory). This change makes makes the CPU_HAS_SOFTWARE_INTERRUPT_STACK and CPU_HAS_HARDWARE_INTERRUPT_STACK CPU port defines superfluous, since the low level initialization code has all information available via global symbols. This change makes the CPU_ALLOCATE_INTERRUPT_STACK CPU port define superfluous, since the interrupt stacks are allocated by confdefs.h for all architectures. There is no need for BSP-specific linker command file magic (except the section placement), see previous ARM linker command file as a bad example. Remove _CPU_Install_interrupt_stack(). Initialize the hardware interrupt stack in _CPU_Initialize() if necessary (e.g. m68k_install_interrupt_stack()). The optional _CPU_Interrupt_stack_setup() is still useful to customize the registration of the interrupt stack area in the per-CPU information. The initialization stack can reuse the interrupt stack, since * interrupts are disabled during the sequential system initialization, and * the boot_card() function does not return. This stack resuse saves memory. Changes per architecture: arm: * Mostly replace the linker symbol based configuration of stacks with the standard <rtems/confdefs.h> configuration via CONFIGURE_INTERRUPT_STACK_SIZE. The size of the FIQ, ABT and UND mode stack is still defined via linker symbols. These modes are rarely used in applications and the default values provided by the BSP should be sufficient in most cases. * Remove the bsp_processor_count linker symbol hack used for the SMP support. This is possible since the interrupt stack area is now allocated by the linker and not allocated from the heap. This makes some configure.ac stuff obsolete. Remove the now superfluous BSP variants altcycv_devkit_smp and realview_pbx_a9_qemu_smp. bfin: * Remove unused magic linker command file allocation of initialization stack. Maybe a previous linker command file copy and paste problem? In the start.S the initialization stack is set to a hard coded value. lm32, m32c, mips, nios2, riscv, sh, v850: * Remove magic linker command file allocation of initialization stack. Reuse interrupt stack for initialization stack. m68k: * Remove magic linker command file allocation of initialization stack. Reuse interrupt stack for initialization stack. powerpc: * Remove magic linker command file allocation of initialization stack. Reuse interrupt stack for initialization stack. * Used dedicated memory region (REGION_RTEMSSTACK) for the interrupt stack on BSPs using the shared linkcmds.base (replacement for REGION_RWEXTRA). sparc: * Remove the hard coded initialization stack. Use the interrupt stack for the initialization stack on the boot processor. This saves 16KiB of RAM. Update #3459.
* bsps: Support .rtemsstack.* linker input sectionsSebastian Huber2018-06-2720-9/+71
| | | | | | Use a dedicated memory region or place it between the BSS and workspace. Update #3459.
* Remove Clock_driver_support_shutdown_hardware()Sebastian Huber2018-06-278-64/+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.
