This patch refactors granule allocator to remove the 32 granules limitation with the help of a gran_range_s structure and related functions, see "mm_grantable.h" for details. Below are the major functions explaining how this works: - The gran_match() checks if a gran range all in the given state. it gives last mismatch position when fails free range matching. - The gran_search() tries to find the position of a free range. It leverages last mismatch position from gran_match() to speed up the search. range size handling is mainly in gran_match() and gran_set_(). Signed-off-by: Yanfeng Liu <yfliu2008@qq.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.
