arch/x86/include/README.txt
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
This directory holds x86-specific header files. The top-level header files in
|
||||
arch/x86/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
|
||||
architectures. Separating these header file makes it easy to manage such
|
||||
things as differences in sizeof(long) on 32- and 64-bit x86 architectures.
|
||||
|
||||
i486
|
||||
This directory holds definitions 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.
