Add "(void) param;" annotation to address unused parameter warnings.
Found with GCC's warning -Wunused-parameter.
The ACPI change set includes two headers which define debug macros. When
not building for debug, the instantiated inline functions generate
unused parameter warnings from every file they are included in. The
warning was disabled around the macro instantiations.
Many tm27.h implementations were one line with no attribution.
Some were simply including a default non-functional implementation.
Others were including a header file giving an implementation based
on a standard counter/timer. This patch gives attribution based on
the split out being done by Sebastian Huber in 2017.
The RTEMS Software Engineering Guide specifies that the SPDX license
annotation shouldbe the first line of the file and not part of the
copyright/license comment block.
- Move the APIC implementation to its on file instead of having it in clock.c;
- Use the MADT for retrieving the Local APIC base address;
- Initialize the APIC during interrupt initialization.
Add a method for initializing the ACPICA table subsystem earlier than
the initilization of the entire ACPICA subsystem. Also add a method to
walk through the subtables of an ACPI table
- Implements necessary ACPICA OS Services Layer interfaces;
- Retrieve the RSDP from the FreeBSD Bootloader for amd64 or from multiboot2 for amd64efi;
- Add ACPI initialization routine;
- Use ACPI in bsp_reset.
Makes the code in bsp/x86_64/amd64/start/start.S and the stack frame
setup by _CPU_Context_Initialize align the stack properly according to
what is expected by the x86-64 SysV ABI
Add directives to get and set the priority of an interrupt vector.
Implement the directives for the following BSP families:
* arm/lpc24xx
* arm/lpc32xx
* powerpc/mpc55xxevb
* powerpc/qoriq
Implement the directives for the following interrupt controllers:
* GICv2 and GICv3 (arm and aarch64)
* NVIC (arm)
* PLIC (riscv)
Update #5002.
The new amd64efi BSP supports:
- multiboot2 boot format. Runs well with GRUB.
- console based on either EFI simple text output or GOP-based framebuffer
- clock based on EFI event/timer API
- early console using either hard-wired PC-AT serial or just memory buffer
- with EFI support disabled the BSP is more or less equivalent to amd64 BSP
with multiboot2 support
The ABI flags for the amd64 BSP contain the -Werror=return-type flag. There is no reason for this to be there so it has been removed. The same option has also been removed amd64.cfg file.
Sort the .noinit* input sections by name first, then by alignment if two
sections have the same name. This allows the placement of begin/end symbols to
initialize some areas with a special value.
Update #4678.
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.
Add rtems_interrupt_raise_on() and rtems_interrupt_clear().
Add a default implementation which just returns RTEMS_UNSATISFIED for
valid parameters.
Update #3269.
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.
