 Compatibility Concerns
 * [#16499](https://github.com/apache/nuttx/pull/16499) [BREAKING] fs/vfs: Separate file descriptors from file descriptions
 This PR is a rework of the NuttX file descriptor implementation. The goal is two-fold:
 Improve POSIX compliance. The old implementation tied file description
 to inode only, not the file struct. POSIX however dictates otherwise.
 Fix a bug with descriptor duplication (dup2() and dup3()). There is
 an existing race condition with this POSIX API that currently results
 in a kernel side crash.
 The crash occurs when a partially open / closed file descriptor is
 duplicated. The reason for the crash is that even if the descriptor is
 closed, the file might still be in use by the kernel (due to e.g. ongoing
 write to file). The open file data is changed by file_dup3() and this
 causes a crash in the device / drivers themselves as they lose access to
 the inode and private data.
 The fix is done by separating struct file into file and file descriptor
 structs. The file struct can live on even if the descriptor is closed,
 fixing the crash. This also fixes the POSIX issue, as two descriptors
 can now point to the same file.
 The implementation of this PR is based on the modifications made in #16361.
 Thank you @pussuw

 IMPACT
 Remove the FS_REFCOUNT config because reference counting is a very necessary feature
 that is required in many scenarios to ensure stability.
 Rename the functions fs_getfilep, fs_putfilep, and fs_reffilep to file_get, file_put,
 and file_ref respectively, to unify the naming convention to file_xxx, such as file_open,
 file_ioctl, etc.
 Introduce a new fd (file descriptor) structure. If multiple file descriptors (fds) are in
 a dup relationship, they can share the same file entity to implement the dup functionality.
 Modify the functions nx_close_from_tcb, nx_open_from_tcb, nx_dup2_from_tcb,
 and nx_dup3_from_tcb to fdlist_open, fdlist_close, fdlist_dup2, and fdlist_dup3 respectively,
 to uniformly operate on file descriptors using fdlist.

 		The ARM9 processor family is built around the ARM9TDMI processor and
 		incorporates the 16-bit Thumb instruction set. The ARM9 Thumb family
 		includes the ARM920T and ARM922T cached processor macrocells:
 		- Dual 16k caches for applications running Symbian OS, Palm OS,
 		  Linux and Windows CE,
 		- Dual 8k caches for applications running Symbian OS, Palm OS, Linux

 		Arm926EJ-S is the entry point processor capable of supporting full
 		Operating Systems including Linux, WindowsCE, and Symbian.
 		The ARM9E processor family enables single processor solutions for
 		microcontroller, DSP and Java applications. The ARM9E family of
 		products are DSP-enhanced 32-bit RISC processors, for applications
 		requiring a mix of DSP and microcontroller performance. The family
 		includes the ARM926EJ-S, ARM946E-S, ARM966E-S, and ARM968E-S
 		processor macrocells. They include signal processing extensions to
 		enhance 16-bit fixed point performance using a single-cycle 32 x 16
 		multiply-accumulate (MAC) unit, and implement the 16-bit Thumb
 		instruction set. The ARM926EJ-S processor also includes ARM Jazelle
 		technology which enables the direct execution of Java bytecodes in
 		hardware.

Lars Kruse	b3dd8b2796	arch/arm/rp2040: merge conflicting definitions of `hw_*` functions 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`.

chao an	cf616fd619	arch/arm/armv8-m: stack pointer should be 8-byte aligned in signal context 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; \| } 2. before this change: \| NuttShell (NSH) NuttX-12.10.0 \| nsh> hello \| 4398046527890440 \| 4398046527890472 \| 4398046527890504 \| 4398046527890536 3. after this change: \| NuttShell (NSH) NuttX-12.10.0 \| nsh> hello \| 1024000 \| 1024000 \| 1024000 \| 1024000 Signed-off-by: chao an <anchao.archer@bytedance.com>	2025-09-27 21:41:20 +08:00

MASZ	94ad260843	arch/arm/stm32h7: Fix and enhance WWDG (Window Watchdog) support This patch addresses several issues and adds enhancements to the WWDG (Window Watchdog) implementation for the STM32H7 platform. The changes include: - Extend the definitions of WWDG_CFR_PCLK1 macros to support dividers up to 128, and update the stm32_settimeout() function to consider this extended range. - Fix the "elapsed" calculations in the stm32_getstatus() function to ensure correct time remaining calculations. - Clear the EWIF (Early Wakeup Interrupt Flag) bit in the stm32_start() function, as this bit might be set by hardware before the watchdog is actually started. - Initialize the WWDG clock in the RCC_APB3ENR register and set the RCC_GCR_WW1RSC bit as per the STM32 reference manual to ensure proper behavior when enabling the WWDG1.
