in SMP, signal processing cannot be nested, we use xcp.sigdeliver to identify whether there is currently a signal being processed, but this state does not match the actual situation
One possible scenario is that signal processing has already been completed, but an interrupt occurs, resulting in xcp.sigdeliver not being correctly set to NULL,
At this point, a new signal arrives, which can only be placed in the queue and cannot be processed immediately
Our solution is that signal processing and signal complete status are set in the same critical section, which can ensure status synchronization

1. Get the value of sp from dump regs when an exception occurs,
to avoid getting the value of fp from up_getsp and causing
incomplete stack printing.
2. Determine which stack the value belongs to based on the value
of SP to avoid false reports of stack overflow

Add support to select WPA3-SAE while connecting to an AP. Please
note that STA mode sets a security threshold, i.e, it was able to
connect to a WPA3-SAE network prior to this change because it
connects to an equally or more secure network than the set
threshold. Considering this patch, the device is now able to
ignore WPA2-PSK APs when WPA3 is set.

The Inter-Processor Interrupt that pauses the other CPU generates
a level-1 interrupt which sets the PS.EXCM. This level-1 interrupt
is treated as an Exception and the bit PS.EXCM bit is automatically
reset on return from Exception. However, this is not the case here
because we are changing the execution to the signal trampoline.
Restoring the PS register with the PS.EXCM bit set would cause any
other exception to deviate execution to the DEC (double exception
vector), avoiding it to be treated correctly. According to the
xtensa ISA: "The process of taking an interrupt does not clear
the interrupt request. The process does set PS.EXCM to 1, which
disables level-1 interrupts in the interrupt handler. Typically,
the PS.EXCM is reset to 0 by the handler, after it has set up the
stack frame and masked the interrupt." Clean the saved PS.EXCM to
1) avoid an exception from being properly treated and 2) avoid
interrupts to be masked while delivering the signal.
Summary:
- Support arm64 pmu api, Currently only the cycle counter function is supported.
- Using ARM64 PMU hardware capability to implement perf interface, modify all
perf interface related code.
- Support for pmu init under smp.

This commit fixes#7857 and #7193 by saving Wi-Fi parameters and
set them at once, avoiding unknown behaviors of the Wi-Fi driver.
This commit also enables setting the auth of the STA/softAP modes
while connecting to/providing the wireless network.
* Remove the 'COEXISTENCE' suffix from Wi-Fi's STA + SoftAP mode.
Coexistence usually refers to Wi-Fi + BLE, instead of Wi-Fi's
operation mode;
* Remove commented debug code;
* Remove outdate function descriptions;
1) Wi-Fi driver libs from Espressif ESP-IDF release/v5.0;
2) Station mode only;
3) WPA2-PSK and WPA3-SAE enabled;
Not yet supported (WIP):
- SoftAP mode;
- 802.11k, 802.11v and 802.11R;
- Power Save mode;
- BLE Coexistance;
NuttX kernel should not use the syscall functions, especially after
enabling CONFIG_SCHED_INSTRUMENTATION_SYSCALL, all system functions
will be traced to backend, which will impact system performance.

Summary:
- It is applicable to esp32 products and uses the himem part
of 8M psram by creating character devices.
Impact:
- None
Testing:
- Use esp32-wrover series products for more than 1000 functional verifications.
In order to turn longjmp context-switch safe, it's necessary
to disable interrupts before modifying windowbase and windowstart.
Otherwise, after a context switch, windowstart and windowbase
would be different, leading to a wrongly set windowstart bit due to
longjmp writing it based on the windowbase before the context switch.
This corrupts the registers at the next window overflow reaching
that wrongly set bit.
*Background:*
This PR is related to an issue first observed on ESP-IDF
https://github.com/espressif/esp-idf/issues/5229 and it was, then,
checked on NuttX using a test application.
*The test application:*
To check if the problem affects ESP32, ESP32-S2 and ESP32-S3 on
NuttX, it was created an application based on:
https://en.cppreference.com/w/c/program/longjmp
The application creates 16 tasks (`#define NUMBER_OF_TASKS 16`)
that implements the following daemon:
```
static int setjmp_longjmp_daemon(int argc, char *argv[])
{
for (int i = 0; i < NUMBER_OF_TASKS * 2; i++)
{
jmp_buf env;
volatile int count = 0;
if (setjmp(env) != UINT16_MAX)
{
foo(&env, ++count);
}
}
sem_post(&g_sem);
return EXIT_SUCCESS;
}
```
The main function also initializes a semaphore to avoid application
exiting before tasks return successfully:
```
sem_init(&g_sem, 0, -NUMBER_OF_TASKS);
```
Finally, the round-robin interval was lowered to 1ms to raise the
chances of the longjmp being interrupted by a context switch
(`CONFIG_RR_INTERVAL=1).
This setup was able to reproduce the problem prior to this patch
being applied.
It takes about 10 cycles to obtain the task list according to the task
status. In most cases, we know the task status, so we can directly
add the task from the specified task list to reduce time consuming.
