Add an option that configure the number of regular group conversions
that will trigger a DMA callback transfering data to the upper-half driver.
By default this value is 1 and the driver behaves the same as before
the change. Increasing this value allows to reduce the number of
DMA interrupts and achieve higher sampling rates.
DMA support for H5 and H7 is not complete so this change has no effect,
but for consistency they have also been modified.
The naming between ports has also been unified:
- dmabuffer -> r_dmabuffer
- nchannels -> rnchannels
- chanlist -> r_chanlist
- jchanlist -> j_chanlist

we are using segger RTT protocol over shared memory for two core log/trace: one is NuttX another Linux/Windows. But the base address of shared memory can only be known at runtime, so we change SEGGER_RTT_UNCACHED_OFF from macro to global variable, and update to the correct g_segger_offset after the shared memory is initialized by:
g_segger_offset = (uintptr_t)ishmem - (uintptr_t)&_SEGGER_RTT;

When writing to the next sector after the forward position has been written
by seek, the old sector buffer is used, which may corrupt the file system.
Therefore, the sector buffer must always be updated after a writing by seek.

Introduces two documentation additions. First, the RFC 5424 support is
documented on the main syslog documentation page, with information about
how to use it effectively. Second is the application documentation for
the `syslogd` application addition, which enables easy use of the new
RFC 5424 support.

Initial implementation of RFC 5424 support (syslog protocol). Allows
users to force-format the syslog output in a RFC 5424 compatible way,
making NuttX systems 'originators' that are able to interface with
syslog 'collectors' and 'relays' (useful for logging to syslog servers).
In addition to regular formatting options for syslog output, users can
also add structured data (currently only timeQuality is implemented,
assuming no sync and no timezone is no known). Facilities and severities
now also follow RFC 5424. Support for additional features (like
more sdata elements, msgid, etc.) will need to be built into the syslog
implementation if desired.
__start should call up_perf_init, initialization of hardware performance
counter, if CONFIG_ARCH_PERF_EVENTS option is set. This allows the
usage of ARM cycle count register DWT_CYCCNT in benchmark
measurements instead of software clock.

A deadlock occurs for priv->lock when uart_xmitchars is called from
within imx9_txint. This is because uart_xmitchars does a callback to
imx9_txint and tries to acquire the lock again.
However, there is no reason to hold the lock over uart_xmitchars, as it
has its own lock for mutual exclusion. Only the UART device needs to
be protected, and priv->lock does that.

Update the Python script based on the PR "Separate file
descriptors from file descriptions" in fs/vfs.
Signed-off-by: dongjiuzhu1 <dongjiuzhu1@xiaomi.com>
This patch is a rework of the NuttX file descriptor implementation. The
goal is two-fold:
1. Improve POSIX compliance. The old implementation tied file description
to inode only, not the file struct. POSIX however dictates otherwise.
2. 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.

1. The call to file_close_without_clear in file_dup3 does not clear
the tag information, so there is no need to back it up.
2. file_dup3 don't need to copy tag information, tag is only valid for fd.

Previously, this config was added to ensure that the size of the struct
file remained unchanged, thereby preventing the Flash memory of
resource-constrained MCUs from being unnecessarily increased.
However, we have now refactored the relationship between struct fd and struct file,
reducing their memory footprint in both Flash and RAM.
Consequently, this config can be removed.
