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.
