* riscv: Use zicsr architecture extensionSebastian Huber2022-02-252-1/+8
| | | | | | | | | | This is required for ISA 2.0 support, see chapter "Zicsr", Control and Status Register (CSR) Instructions, Version 2.0 in RISC-V Instruction Set Manual, Volume I: RISC-V User-Level ISA
* bsps/riscv: Add missing includeSebastian Huber2022-02-251-0/+1

* bsp_specs: Delete last remnants of these.Joel Sherrill2021-11-292-0/+0
| | | | Updates #3937.
* build: Remove old build systemSebastian Huber2021-09-216-534/+0
| | | | | Close #3250. Close #4081.
* score: Canonicalize _CPU_Fatal_halt()Sebastian Huber2021-07-282-2/+4
| | | | | | | | Move _CPU_Fatal_halt() declaration to <rtems/score/cpuimpl.h> and make sure it is a proper declaration of a function which does not return. Fix the type of the error code. If necessary, add the implementation to cpu.c. Implementing _CPU_Fatal_halt() as a function makes it possible to wrap this function for example to fully test _Terminate().
* bsps/irq: bsp_interrupt_facility_initialize()Sebastian Huber2021-07-272-6/+2
| | | | | | Do not return a status code in bsp_interrupt_facility_initialize() since this leads to unreachable code in bsp_interrupt_initialize(). Use RTEMS_DEBUG assertions in bsp_interrupt_facility_initialize() if necessary.
* bsps/irq: bsp_interrupt_set_affinity()Sebastian Huber2021-07-264-6/+10
| | | | | | Return a status code for bsp_interrupt_set_affinity(). Update #3269.

* bsps/irq: bsp_interrupt_vector_disable()Sebastian Huber2021-07-262-2/+5
| | | | | | Return a status code for bsp_interrupt_vector_disable(). Update #3269.
* bsps/irq: bsp_interrupt_vector_enable()Sebastian Huber2021-07-262-2/+5
| | | | | | Return a status code for bsp_interrupt_vector_enable(). Update #3269.
* bsps/irq: Add rtems_interrupt_is_pending()Sebastian Huber2021-07-262-0/+22
| | | | | | Add a default implementation which just returns RTEMS_UNSATISFIED. Update #3269.
* bsps/irq: Add rtems_interrupt_get_attributes()Sebastian Huber2021-07-262-0/+16
| | | | | | | Add a default implementation which clears the attributes to zero and just returns RTEMS_SUCCESSFUL for valid parameters. Update #3269.
* bsps/irq: Add rtems_interrupt_raise()Sebastian Huber2021-07-262-0/+46
| | | | | | | | | Add rtems_interrupt_raise_on() and rtems_interrupt_clear(). Add a default implementation which just returns RTEMS_UNSATISFIED for valid parameters. Update #3269.
* bsps/irq: Add rtems_interrupt_vector_is_enabled()Sebastian Huber2021-07-262-0/+22
| | | | | | | Add a default implementation which just returns RTEMS_UNSATISFIED for valid parameters. Update #3269.
* bsps/irq: Remove BSP_INTERRUPT_VECTOR_MAXSebastian Huber2021-06-242-2/+0
| | | | | | This define is no longer used. Update #3269.
* bsps/irq: Add BSP_INTERRUPT_VECTOR_COUNTSebastian Huber2021-06-242-0/+2
| | | | | | | | | | | | | 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 Huber2021-06-242-4/+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.
* grlib: Add apbuart_outbyte_wait()Sebastian Huber2021-06-171-1/+2
|
* grlib: Remove NL -> CR in apbuart_outbyte_polled()Sebastian Huber2021-06-171-1/+1
| | | | This is already done in rtems_putc().
* grlib: Add ambapp_plb()Sebastian Huber2021-06-175-16/+25
| | | | | Replace the global variable ambapp_plb with a function to allow an automatic on demand initialization.
* bsps: Support RTEMS_NOINIT in linkcmdsSebastian Huber2021-05-022-0/+11
| | | | Update #3866.
* bsps: Remove networking driversVijay Kumar Banerjee2021-04-071-59/+0
| | | | Update #3850
* bsps/riscv: Add per cpu clock interruptJan Sommer2021-03-231-10/+49
| | | | - Fixes failure of test smpclock01

| | | | | | Change license to BSD-2-Clause according to file history. Update #3053.
* bsps: Replace bsp_specs with an empty fileSebastian Huber2021-01-282-18/+0
| | | | | | | This fixes an issue with the latest tool chain which adds the default linker script in the endfile specification. Update #3250.
* bsps: Add missing DWARF 5 sectionsSebastian Huber2021-01-261-3/+5
| | | | Sort alphabetically.
* bsps: Support DWARF 5 sectionsSebastian Huber2021-01-251-20/+30
| | | | GCC 11 uses DWARF 5 by default.
* Add networking support for griscv bspJiri Gaisler2020-11-093-1/+74
| | | | | | | * Only GRETH device supported for now * Fix endian problem in GRETH driver * Remove SPARC assembly from greth.c * Builds with both autoconf and waf
* grlib: Add and use irqmp_has_timestamp()Sebastian Huber2020-10-101-1/+1
| | | | | | | Replace leon3_irqmp_has_timestamp() with irqmp_has_timestamp() and move it to grlib.h. Close #4128.
* bsps/riscv: Add bsp_fdt_map_intr()Sebastian Huber2020-09-231-0/+6
| | | | This function is required by libbsd.
* riscv: Make sifive_test finisher 4 bytesHesham Almatary2020-09-171-1/+1
| | | | | | QEMU is now stricter with MMIO sizes and accesses. uintptr_t on RV64 is 8 bytes and generates an sd instruction that Store/AMO faults because sifive_test MMIO expects 4 bytes accesses.
* bsps/riscv: Use far jump to boot_card()Sebastian Huber2020-09-151-1/+1
| | | | | | Use a far jump to avoid errors like this: relocation truncated to fit: R_RISCV_JAL against symbol `boot_card'
* htif_console_handler is defined in htif.cHesham Almatary2020-09-061-1/+1
| | | | closes #4069.
* bsps: Always install IPI in SMP configsSebastian Huber2020-08-311-12/+9
| | | | | | | The inter-processor interrupt (IPI) may be used to process per-CPU jobs. See for example the blocked handler in T_interrupt_test(). Update #3199.
* bsps/riscv: Fix multiple definitionSebastian Huber2020-04-101-2/+0
|
* imfs: Replace devfs with an IMFS specializationSebastian Huber2020-03-091-3/+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.
* Use RTEMS_SYSINIT_ORDER_LAST_BUT_5Sebastian Huber2020-02-041-1/+1
| | | | | | | | Use RTEMS_SYSINIT_ORDER_LAST_BUT_5 instead of RTEMS_SYSINIT_ORDER_LAST to allow applications and support functions to place system initialization handlers behind the standard handlers. Update #3838.
* bsps: Add RamEnd to linker command filesSebastian Huber2020-02-041-0/+1
| | | | Update #3838.

* riscv: Add new offending input sections to the linker scriptHesham Almatary2019-10-271-0/+5
|
* riscv: Add NOLOAD directive to the .work sectionHesham Almatary2019-10-271-1/+1
| | | | ld.lld defaults .work to PROGBITS otherwise
* riscv: Address differences in the linkerscript between GNU LD and LLVM/LLDHesham Almatary2019-10-271-51/+51
| | | | | | | | | | LLVM/LLD does not support STARTUP and ALIGN_WITH_INPUT directives that GNU LD support. INPUT and ALIGN(8) are supported by LLVM/LLD and can replace the unsupported STARTUP/ALIGN_WITH_INPUT directives. The commit conditionally adds the supported directive that linkers can understand depending on the toolchain used to compile RTEMS i.e., clang or gcc. Clang is assumed to use LLD by default.
* riscv: Generate linkcmds.base from the shared linkcmds.base.inHesham Almatary2019-10-271-0/+0
| | | | | This commit moves the existing linkcmds.base to linkcmds.base.in in order to make it configurable by autotools.
* riscv: add freedom E310 Arty A7 bspPragnesh Patel2019-10-237-5/+312
| | | | | | | Added support for Sifive Freedom FE310 soc on Arty A7 FPGA board. Update #3785. Signed-off-by: Pragnesh Patel <pragnesh.patel@sifive.com>
* score: Rename _SMP_Get_processor_count()Sebastian Huber2019-04-111-9/+9
| | | | | | | Rename _SMP_Get_processor_count() in _SMP_Get_processor_maximum() to be in line with the API level rtems_scheduler_get_processor_maximum(). Update #3732.
