support arch:
sim x86
sim x86_64
arm32 all series
If we need to support more architectures in the future,
just add the 'g_tcbinfo' of the corresponding architecture
support thread command:
1. thread <id>
switch thread
2. info thread
list all thread info
3. thread apply [all | id list] command
like this:
thread apply all bt
thread apply all bt full
thread apply 1 2 4 bt
thread apply all info r
4. nxsetregs
Set registers to the specified values.
Usage: nxsetregs [regs]
Etc: nxsetregs
nxsetregs g_current_regs[0]
nxsetregs tcb->xcp.regs
Nxsetregs g_pidhash[0].tcb->xcp.regs
Default regs is g_current_regs[0],if regs is NULL,
it will not set registers.
Because NuttX enters exception_common during a crash,
this assembly function manipulates the stack pointer (sp),
causing GDB to be unable to trace back to the first context of the crash.
Instead, it shows the context of the interrupt stack. By using nxsetregs,
it is possible to forcefully set the first context to
the one before the interrupt occurred.
Notice:
Switching threads is achieved by setting registers,
so registers need to be restored before continue,
please use 'c' to continue instead of 'continue'

according to https://github.com/apache/nuttx/pull/7903
it was to fix "the macOS runners occasionally failing".
cython issue workaround seems more important because it always fails.
1. Update all CMakeLists.txt to adapt to new layout
2. Fix cmake build break
3. Update all new file license
4. Fully compatible with current compilation environment(use configure.sh or cmake as you choose)
------------------
How to test
From within nuttx/. Configure:
cmake -B build -DBOARD_CONFIG=sim/nsh -GNinja
cmake -B build -DBOARD_CONFIG=sim:nsh -GNinja
cmake -B build -DBOARD_CONFIG=sabre-6quad/smp -GNinja
cmake -B build -DBOARD_CONFIG=lm3s6965-ek/qemu-flat -GNinja
(or full path in custom board) :
cmake -B build -DBOARD_CONFIG=$PWD/boards/sim/sim/sim/configs/nsh -GNinja
This uses ninja generator (install with sudo apt install ninja-build). To build:
$ cmake --build build
menuconfig:
$ cmake --build build -t menuconfig
--------------------------
2. cmake/build: reformat the cmake style by cmake-format
https://github.com/cheshirekow/cmake_format
$ pip install cmakelang
$ for i in `find -name CMakeLists.txt`;do cmake-format $i -o $i;done
$ for i in `find -name *\.cmake`;do cmake-format $i -o $i;done

The following warning is emitted when building with GCC 12.2.0:
"the comparison will always evaluate as ‘true’ for the address of ‘g_parm’ will never be NULL [-Waddress]"
As g_param is an array of char[]. each member should have an actual address, so the validation in each if statement is not required.
Allows boards to supply their own gnu-elf linker script, used when building Nuttx applications and CONFIG_BUILD_KERNEL.
This is useful when building fully-linked applications (see #9395).
This patch add an example and pyhton base modules:
1.add memdump.py is an example to analyze memory
usage by python script.
2.add The most basic data structure analysis, like list, etc.
future ideas:
Maybe we can add modules related to "sched, drivers, arch, fs.." to
automatically analyze scripts to debug some problems

This PR is a modification that optimizes priority inheritance
for only one holder. After the above modifications are completed,
the mutex lock->unlock process that supports priority inheritance
can be optimized by 200 cycles.
Before modify: 2000 cycle

This commit aims to provide a way to get the current applied defconfig on runtime by providing CONFIG_BASE_DEFCONFIG that is updated when the configure and build scripts are run.
The "CONFIG_APPS_DIR" generated in .config has double quotes and is not recognized as a path by most make systems. This commits removes these double quotes to make the compile successfully.
The offset of the relevant registers in xcp will change after
enabling the FPU, this PR will add fpu offset correct the register offset

Currently when we modify some Kconfig related to some chip or
some architecture we need to run refresh.sh to all boards that
is too slow (more than one hour to finish).
This patch modify the script to update only the boards configs
of an specific chip or only the boards of an specific architecture.
Examples:
$ ./tools/refresh.sh --silent --defaults arch:renesas
Normalize us7032evb1/ostest
Normalize us7032evb1/nsh
Normalize skp16c26/ostest
Normalize rx65n-rsk2mb/netnsh
Normalize rx65n-rsk2mb/ipv6
Normalize rx65n-rsk2mb/nsh
Normalize rx65n-rsk1mb/netnsh
Normalize rx65n-rsk1mb/nsh
Normalize rx65n-grrose/netnsh
Normalize rx65n-grrose/ipv6
Normalize rx65n-grrose/nsh
Normalize rx65n/nsh
It updates the boards from all 'renesas' architecture (m9c, rx65n, sh1)
$ ./tools/refresh.sh --silent --defaults chip:rx65n
Normalize rx65n-rsk2mb/netnsh
Normalize rx65n-rsk2mb/ipv6
Normalize rx65n-rsk2mb/nsh
Normalize rx65n-rsk1mb/netnsh
Normalize rx65n-rsk1mb/nsh
Normalize rx65n-grrose/netnsh
Normalize rx65n-grrose/ipv6
Normalize rx65n-grrose/nsh
Normalize rx65n/nsh
It updates all the boards from renesas chip 'rx65n' family
The syntax check of kconfiglib is stricter than kconfig-frontends,
but the warnings of kconfiglib are not catched by Makefile. Since kconfiglib
is implemented by python, the return value of the shell is always zero($?),
In this PR, I redirected the relevant standard errors to the file to check
whether the kconfig warning is occurred
