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.
