It contains enough code for testing the existing user plugin support
|
||||
in Bochs and creates a device that installs a 32-bit r/w register at
|
||||
i/o address 0x1000.
|
||||
This example also show how to install and handle user-defined config
|
||||
options for bochsrc, command line and the config interface. In this
|
||||
demo it is used to specify the reset value.
|
||||
For user plugin support Bochs must be configured with plugins enabled.
|
||||
Compiling with plugin support is known to work on Linux and Windows
|
||||
(Cygwin or MinGW/MSYS).
