Since the alignment of the signal context is affected by XCPTCONTEXT_SIZE in
different Kconfig, sometimes the stack pointer is not aligned to 8 bytes, this
is not what the software and compiler expect, for example, if va_list() obtains
wide data of type long long, the offset will be wrong, So in this commit, we set
stack-aligned the base offset so that the correct offset will be set during context
restoration.
1. test code:
| void signal_handler(int signo, siginfo_t *info, void *context) {
| long long ttt = 1024000;
| printf("%lld\n", ttt);
| }
|
| struct itimerspec its = { .it_value.tv_sec = 1,
| .it_value.tv_nsec = 0,
| .it_interval.tv_sec = 1,
| .it_interval.tv_nsec = 0
| };
|
| int main(int argc, FAR char *argv[])
| {
| struct sigevent evp;
| timer_t timer_id;
|
| memset(&evp, 0, sizeof(evp));
| evp.sigev_notify = SIGEV_SIGNAL | SIGEV_THREAD_ID;
| evp.sigev_signo = SIGALRM;
| evp.sigev_notify_thread_id = gettid();
|
| timer_create(CLOCK_REALTIME, &evp, &timer_id);
|
|
| struct sigaction sa;
| memset(&sa, 0, sizeof(sa));
| sa.sa_sigaction = signal_handler;
| sa.sa_flags = SA_SIGINFO;
| sigemptyset(&sa.sa_mask);
|
| sigaction(SIGALRM, &sa, NULL);
|
| timer_settime(timer_id, 0, &its, NULL);
|
| while (1)
| sleep(1);
|
| return 0;
| }

This commit adds documentation to the almost empty `calib_udelay` page
as part of #11081. It provides reasoning for the example, an explanation
of what it does and why `CONFIG_BOARD_LOOPSPERMSEC` is necessary, and
also shows some example console output of the program.

This patch will report events in the following scenarios:
1. Events that have changed but not been waited for before being added to
the interest list.
2. Events that occur after `epoll_wait()` returns and before it is called
again.

The functions `hw_write_masked` and `hw_xor_bits` (as defined in
pico-sdk) were defined in NuttX twice.
Additionally these definitions were in conflict (one lacked the
`volatile` modifier).
Now these functions and their dependencies are defined in a new header
file.
Its name is based on the filename of the original definition in
pico-sdk:
src/rp2_common/hardware_base/include/hardware/address_mapped.h
This change should fix the potential issue of GPIO operations failing
due to compiler optimizations caused by the absence of `volatile`.

In certain cases, when the event-wait thread is awakened,
it needs to know the specific mask bit that triggered it,
so that it can branch to different paths accordingly.
This patch introduces the nxevent_getmask function to address this requirement.

Change:
Replace list_delete_init() with list_delete() in nxevent_post.
Reason:
PR 16933 removed list_delete() in nxevent_wait() and allow other task
to preempt event-wait thread after list_add_tail() option, the even-post thread
can preempt it at this time and do list_delete_init().
The problem is that list_delete_init() will make list_in_list() return true, so
DEBUGASSERT(!list_in_list(&(wait->node))); will fail in nxevent_wait() after the event-wait thread
returns.

There are cases that users do not want the event wait object to be allocated automatically
in the stack as a temporary varialbe in nxevent_tickwait, since multiple threads will
access the varialbe, they want to allocate the object as a global variable for safety
control or easy debug. To solve this problem, this patch add a new function nxevent_tickwait_wait
implementation to give user the chance to pass the global wait object to it.
