In addtion to 1023, the GICC_IAR register may return 1022 as a special value.
Simply check for a valid interrupt vector for the dispatching.
Check the GICC_IAR again after the dispatch to quickly process a next interrupt
without having to go through the interrupt prologue and epiloge.
Make the clock driver parameters configurable. Use the maximum counter
frequency to get the best time resolution. Decouple the CPU counter from the
timecounter. Make the tick catch up handling more robust. Add a validation
test for the tick catch up.
The processor mask implementation uses flsl() from <strings.h> which is
only BSD visible. Move the implementation to a separate header file to
hide it from the API level. This fixes build errors with GCC 14.
GitLab has it's own flavour and I've kept that in mind.
This greatly simplifies the document as well GitLab is quite a bit more verbose
than Trac was no need to replicate information.
This is just a first revision we can expand it as necessary.
It's clearly not required not sure why the gitlab-org repo uses it. I think
it's fine because * is a wildcard and ** is typically used for a recursive glob.
While it works it's not necessary.
This also adds stubs in for the rest of the architectures and owners.
Note that any users not currently on our test instance aren't in here we will
have to add them after.
Replace the BSP_CONSOLE_MINOR BSP option for the Xilinx Zynq BSPs with the new
BSP option ZYNQ_UART_KERNEL_IO_BASE_ADDR. Move the kernel I/O support to a
shared file.
Make the initialization and polled functions independent of the Termios
context. This helps to implement the kernel I/O support without a dependency
on the Termios framework.
Move declarations of bsp_interrupt_get_affinity() and
bsp_interrupt_set_affinity() to <bsp/irq-generic.h>. Canonicalize the
<bsp/irq.h> includes.
Implement bsp_interrupt_get_affinity() and bsp_interrupt_set_affinity() only if
needed (usually RTEMS_SMP).
Provide stub implementations for i386 to fix build errors.
The parameters are unused due to API constraints. The functions are
used through function pointers. Alternative implementations may use the
parameters.
Update #4862.
Pass the parameter of the clock interrupt handler to
Clock_driver_support_at_tick() and Clock_driver_timecounter_tick(). This makes
it possible to use the interrupt handler argument in clock drivers.
Use the interrupt handler provided by Clock_driver_support_install_isr() to
avoid local delarations of Clock_isr().
Update #4862.
