When the VIRTIO_RPMSG_F_CPUNAME feature is not negotiated, the driver previously would crash due to DEBUGASSERT. This commit adds support for a fallback mechanism: 1. Add rpmsg_virtio_probe_cpuname() API that accepts an optional cpuname parameter to be used when VIRTIO_RPMSG_F_CPUNAME is not available. 2. Modify rptun driver to pass the cpuname from rptun device config to rpmsg_virtio_probe_cpuname(). 3. Refactor rptun device register/unregister to prioritize RPMSG device handling before other virtio device types. This ensures the system works correctly in scenarios where the remote side does not support the VIRTIO_RPMSG_F_CPUNAME feature. Signed-off-by: Bowen Wang <wangbowen6@xiaomi.com>
Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).
For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.
Getting Started
First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.
Documentation
You can find the current NuttX documentation on the Documentation Page.
Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.
The old NuttX documentation is still available in the Apache wiki.
Supported Boards
NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.
