usage:
1. Connect Jlink, start JLinkGDBServer
JLinkGDBServer -if SWD -device stm32h743zi -speed 16000
2. Listen to the RTT port data and forward it to the virtual serial port
sudo socat -d -d PTY,link=/dev/ttyRTT0,raw,ignoreeof TCP:127.0.0.1:19021,reuseaddr
3. Read serial data

1. as we can use fork to implement vfork, so we rename the vfork to
fork, and use the fork method as the base to implement vfork method
2. create the vfork function as a libc function based on fork

In order to support the compilation of third-party library, we encounter
some situations where the macro is not defined, refer to the common
implementation of other systems and add relevant definitions.

There is no need to use global spinlock to protect netdev
specific data counters. Allocate per-netdev specific spinlock
to get better locking granularity.

LED effects must be implemented in the lower-half of the LED driver.
The interface is designed to supports the following LED effects:
- intenisty (PWM)
- Bling (Timer)
- Fade in, Fade out (Ramp)
since symbols defined in arch/elf.h is also used in other case, for example:

It is used to write the log message to the channel immediately
when the log message is generated in the interrupt context, which
is faster than the normal force callback.

syslog_force is used to force the syslog output to the

This function will use gcc's function
__builtin_dynamic_object_size and __builtin_object_size
Its function is to obtain the size of the object through compilation,
so as to judge whether there are out-of-bounds operations in commonly used functions.
It should be noted that the option -O2 and above is required to enable this function

When asserting, automatically analyze whether
there is a deadlock in the thread, and if there
is a deadlock, print out the deadlocked thread.
The principle is to analyze whether there is
a lock ring through the tcb holder.
