ESP32-P4 uses simple boot mode without a separate bootloader,
so merging binaries into a single 16MB file is unnecessary.
Removing this option allows 'make flash' to write only the
actual firmware (~380KB) instead of a padded 16MB image,
reducing flash time from ~55s to ~4.5s.

The STM32 DMA NDTR/CNDTR transfer-count register is 16 bits wide on
every STM32 series the in-tree driver supports (IPv1 CNDTR, IPv2
SxNDTR). spi_exchange()'s DMA path forwarded the caller's full
nwords to stm32_dmasetup(), so a single SPI_EXCHANGE() of >= 65536
words silently programmed NDTR to (nwords & 0xffff). When the
truncated count was zero - the typical case for an exact 64 KiB
transfer (flash erase block, FAT cluster, common DMA staging
buffer) - the stream completed instantly with no transfer-complete
interrupt and the caller deadlocked in spi_dmarxwait().
Walk the request in chunks of at most 65535 words inside the
existing DMA branch, reusing the same spi_dma{rx,tx}{setup,start,
wait}() sequence per chunk. Single-descriptor transfers (every
in-tree caller today) are byte-for-byte identical. CONFIG_SPI_TRIGGER
is honored for the first chunk only; subsequent chunks must run
unconditionally because re-arming between chunks of one logical
exchange was never part of the SPI_TRIGGER contract.
Drive-by: rescale priv->buflen-clamped nwords so the DMA
descriptor matches the actually-copied byte count, promote the
spiinfo() format specifier from %d to %zu, and fix two adjacent
comment typos.
See the PR description for reproduction, NSH log and benchmark
numbers (5.12 MB/s, 97.5% of SCK/8 @ 42 MHz on STM32F407 + W25Q128).

Add a CONFIG_FS_PERMISSION Kconfig option for future
filesystem permission support infrastructure.
The option depends on CONFIG_SCHED_USER_IDENTITY and
CONFIG_PSEUDOFS_ATTRIBUTES to ensure task credential
tracking and pseudo-filesystem inode ownership/mode
metadata are available before enabling the feature.
The symbol defaults to n to preserve existing behavior
for current configurations.
No runtime permission enforcement is introduced by
this commit.

* NuttX supports ESP32-P4 >= v3.0 by default.
* In order to run on older chips configuration tuning is required.
* Without configutation tune boot loop happens on older chips.
* Added note on WaveShare ESP32-P4-Nano board that is almost identical
to existing ESP32-P4-Function-EV-Board board, so configs are compatible,
but it has v1.3 chip, thus config tune is required as documented above.
* Added cross-file reference label to esp32p4-function-ev-board.

Three `export VAR ?= $(shell ...)` assignments cause GNU make to
re-run the embedded ${shell ...} every time the variable is exported
to a recipe's environment. That spawns `tools/incdir` and
`tools/define` once per recipe, serialised through the master make
thread, which adds per recipe overhead to multi-job builds.
Wrap each with `ifeq ($(origin VAR),undefined)` + `:=` so the shell
call runs once at parse time while preserving the override semantics
of `?=`.
Measured impact on a 20-core build host is a ~26% speedup of wall
time.

PendSV is the deferred half of the Cortex-M context-switch path: a
higher-priority ISR that wakes a task sets PendSV pending and returns,
and PendSV then performs the register save/restore. This pattern is
only safe when PendSV runs at the lowest priority - otherwise a
peripheral ISR can preempt the context switch mid-update and corrupt
thread state.
The previous write of DEFPRIORITY32 to NVIC_SYSH12_15_PRIORITY in
up_irqinitialize() leaves PendSV at NVIC_SYSH_PRIORITY_DEFAULT (0x80),
the same priority as peripheral IRQs. Read-modify-write the SHPR3 to
lower only the PendSV byte to NVIC_SYSH_PRIORITY_MIN.
This is the canonical ARM Cortex-M priority arrangement and it matches
e.g. this reference:
https://nuttx.apache.org/docs/latest/guides/zerolatencyinterrupts.html (although
worked with a three-bit priority system)
This patch hardens up_irqinitialize against future peripheral-IRQ
prioritisation.
Signed-off-by: Daniel Fanache <dan@rts.ro>
At system startup, the NVIC was configured for proper default priority
only for the first three IPR registers, even though the loop was
executed 13 times - due to a gotcha on what the `NVIC_IRQ_PRIORITY(i)`
macro returns.
IRQs 12-51 stayed at the reset priority of 0 - highest in the system;
so any peripherals issuing those interrupts will shoot through
critical sections that rely on
BASEPRI = NVIC_SYSH_PRIORITY_DEFAULT (0x80).
This can corrupt the TCB ready-to-run list and semaphore wait queues;
this is hard to reproduce (e.g. in ostest) because it requires a
peripheral ISR to land inside a critical section, but the failure
modes range from hangs to wild pointer crashes once it does.
In my case I had SPI and I2C peripherals that were issuing IRQs and
were preempting scheduler and semaphore list operations, causing
corruption.
Step the loop by four and bound it with RP23XX_IRQ_NEXTINT so every
IPR covering IRQs 0..51 is written once with DEFPRIORITY32.

OpenAMP 2025.10.0 removed the deprecated WITH_DCACHE_VRINGS, WITH_DCACHE_BUFFERS and WITH_DCACHE_RSC_TABLE CMake options. The replacement is WITH_DCACHE, which enables VIRTIO_USE_DCACHE for vrings, buffers and resource table cache operations.
Use WITH_DCACHE for CONFIG_OPENAMP_CACHE in the CMake integration so the CMake build matches the Makefile path, which already defines VIRTIO_USE_DCACHE directly.

Add dedicated NEON implementations for mutually aligned medium and long memcpy copies when building with __ARM_NEON__. These paths use NEON multi-register loads and stores while preserving the existing VFP implementation for non-NEON VFP configurations.
NEON builds also define USE_VFP, so select the NEON implementation explicitly before falling back to VFP. Apply the same aligned-copy optimization to the armv7-a, armv7-r, and armv8-r implementations.

When CONFIG_DISABLE_PTHREAD=y, HAVE_GROUP_MEMBERS is undefined and
group_leave() unconditionally calls group_release() for every exiting
thread. This destroys the shared g_kthread_group resources (mutex,
fdlist, task_info) while other kernel threads are still using them,
causing use-after-free crashes.
Fix by checking TCB_FLAG_TTYPE_KERNEL in group_leave() before calling
group_release(), so the entire release path is skipped for kernel
threads. This is safe because g_kthread_group is statically allocated
and its lifetime is the entire system.

current_usec() returns a uint64_t, but it used TICK2USEC(timebase)
to convert scheduler ticks to microseconds. On 32-bit clock_t builds,
TICK2USEC() performs the multiplication in 32-bit arithmetic before the
result is widened.
With CONFIG_USEC_PER_TICK=10000, this wraps after about 71.6 minutes:
UINT32_MAX / 1000000 ~= 4294 seconds
After the wrap, up_timer_gettick() can report time near zero again. This
can leave absolute watchdog timeouts, such as those used by usleep() /
clock_nanosleep(), waiting for a tick value that will not be reached until
the 32-bit scheduler counter wraps.
Cast timebase to uint64_t before multiplying by USEC_PER_TICK so
current_usec() remains monotonic across the 32-bit microsecond boundary.

bluetooth_sendto() uses netdev_findbyindex(conn->bc_ldev + 1) to find
the Bluetooth network device for an HCI socket. netdev_findbyindex
searches by global interface index, but bc_ldev is a 0-based count of
Bluetooth devices only — it bears no fixed relationship to the global
interface index. If any netdev other than a Bluetooth device is
registered before it (e.g. loopback or Ethernet), the Bluetooth device
will not be at global index bc_ldev + 1 and the lookup will return NULL
or the wrong device.
Fix this by replacing netdev_findbyindex with a netdev_foreach walk
using a small callback (bluetooth_dev_byidx_callback) that counts only
NET_LL_BLUETOOTH devices and returns the bc_ldev-th one, regardless of
what else is registered or in what order.

The host interrupt callback was incorrectly using the wrong IRQ for
disconnected. In host mode the same IRQ is used for connect/disconnected
and it must check a status bit to know which one.
When a USB device was unplugged, the host channels were free'd,
but if they happen to be mid-transfer, that transfer was never cancelled
so the USB hardware might still be trying to perfrom a transfer after
was free'd. Fixed by cancelling any transfers on free.

This commit fixes a regression introduced by
89df084b0e. That commit
added a check to ensure iov_base is not NULL, assuming NULL
always represents an inaccessible address.
However, in CONFIG_BUILD_KERNEL mode where CONFIG_ARCH_TEXT_VBASE
is set to 0, address zero is a valid virtual address for the
user-space text segment. The previous check caused libelf to
fail with -EFAULT when attempting to load ELF program headers
into the base of the user address space.
This patch wraps the safety check in a conditional to ensure it is
only executed when address zero is not considered a valid
executable base.
