Add support for running the OS in tickless mode with hrtimer, allowing
the scheduler to operate without periodic ticks while maintaining
high-resolution timer functionality.
Signed-off-by: Chengdong Wang <wangchengdong@lixiang.com>
The hrtimer subsystem is independent of the OS tick mechanism and tickless
mode. It must always be able to reprogram the hardware timer to achieve
nanosecond-level resolution.
A recent update restricted hardware timer reprogramming to tickless mode
only. As a result, hrtimer no longer functions correctly when the scheduler
is running in tick-based mode.
This change removes the incorrect dependency on tickless mode and restores
proper hrtimer operation.

IRQ_TO_NDX() may return a negative value when the IRQ number is invalid
or not mapped. Using this negative value directly as an array index for
g_irqvector causes undefined behavior and potential memory corruption.
This patch adds a bounds check to ensure ndx is non-negative before
accessing the g_irqvector array, returning the error code if invalid.

This patch adds support for the FIOC_FILEPATH ioctl command in the
FAT filesystem, allowing applications to retrieve the full path of
an open file descriptor.
Key features:
- Implements fat_getfilepath() to construct file paths by traversing
parent directories using ".." entries
- Adds fat_findlfnstart() helper to locate the start of LFN sequences
- Supports both FAT12/16 and FAT32 filesystem types
- Handles both regular directories and root directory traversal
This functionality is useful for debugging, logging, and applications
that need to track file paths at runtime.

For the following code, we need to check 'type_attr.form'.
type_attr = DIE.attributes["DW_AT_type"]
base_type_die = dwarfinfo.get_DIE_from_refaddr(xxx)
When type_attr.form==DW_FORM_ref_addr, 'type_attr.value' means
global reference (across compilation units).
When type_attr.form==DW_FORM_ref4, 'type_attr.value' means

2. When legacy boot is configured, vecbase must also be set and

3. Cache must be disabled during Flash operations, so all
Flash-operation-related functions must be placed in IRAM

The dhtxx driver previously returned 0 on success, which violates standard
character device behavior where the number of bytes read should be returned.
It also used non-standard error codes like -1 or -ENOSYS for operational
errors.
This commit fixes the following behavior to comply with POSIX standards:
* Return sizeof(struct dhtxx_sensor_data_s) on success instead of 0.
* Return -EINVAL instead of -ENOSYS/-1 for invalid buffer arguments.
* Return -ETIMEDOUT instead of -1 for sensor timeouts.
* Return -EIO instead of -1 for checksum or parsing errors.

Add a new getrecvbuf callback to the SPI slave device operations
that allows the slave device to provide a pre-allocated receive
buffer directly to the controller. This enables zero-copy data
transfer by allowing the controller to receive data directly into
the device's buffer instead of copying.
Changes:
- Add SPIS_DEV_GETRECVBUF macro and getrecvbuf callback to
spi_slave_devops_s structure in include/nuttx/spi/slave.h
- Implement getrecvbuf in rpmsg_port_spi_slave driver
- Update getdata to return 0 as it's no longer used for this path

- Use port.txq.len instead of cmdhdr->len for TX exchange length
- Use port.rxq.len instead of cmdhdr->len for RX getdata length
