- arch/x86_64/include/README.txt
- ^^^^^^^^^^^^^^^^^^^^^^^^^^^
- This directory holds x86_64-specific header files. The top-level header files in
- arch/x86_64/include simply include corresponding header files from lower lower-
- level chip-specific and architecture-specific directories.
- Architecture-Specific Directories
- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- Architecture-specific directories hold common header files for specific x86_64
- architectures.
- intel64
- This directory holds definitions appropriate for any instantiation of the
- Intel architecture in 64bit long mode.
- 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.
- broadwell
- This is the implementation of NuttX on the Intel Broadwell processors.
