* Simplify EINTR/ECANCEL error handling 1. Add semaphore uninterruptible wait function 2 .Replace semaphore wait loop with a single uninterruptible wait 3. Replace all sem_xxx to nxsem_xxx * Unify the void cast usage 1. Remove void cast for function because many place ignore the returned value witout cast 2. Replace void cast for variable with UNUSED macro |

arch/x86/src/README.txt ^^^^^^^^^^^^^^^^^^^^^^^ This directory holds x86-specific source files. All x86 source reside in lower-level common, chip-specific, and architecture-specific directories. common/ Directory ^^^^^^^^^^^^^^^^^ This directory holds source files common to all x86 architectures. Architecture-Specific Directories ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Architecture-specific directories hold common source files shared for by implementations of specific x86 architectures. i486 This directory holds logic appropriate for any instantiation of the 32-bit i486 architecture. Chip-Specific directories ^^^^^^^^^^^^^^^^^^^^^^^^^ The same x86 architecture may be realized in different chip implementations. For SoC chips, in particular, on-chip devices and differing interrupt structures may require special, chip-specific definitions in these chip- specific directories. qemu This is the implementation of NuttX on the QEMU x86 simulation.
