|
||
* This is code for a text-mode control panel. Note that this file
|
||
* does NOT include bochs.h. Instead, it does all of its contact with
|
||
* the simulator through an object called SIM, defined in siminterface.cc
|
||
* and siminterface.h. This separation adds an extra layer of method
|
||
* calls before any work can be done, but the benefit is that the compiler
|
||
* enforces the rules. I can guarantee that control.cc doesn't call any
|
||
* I/O device objects directly, for example, because the bx_devices symbol
|
||
* isn't even defined in this context.

Musings by Bryce:
|
||
|
||
Now that there are some capabilities here, start moving toward the desired
|
||
model of separation of gui and simulator. Design a method-call interface
|
||
between objects which could later be turned into a network protocol.
|
||
|
||
Most messages go from the control panel to bochs, with bochs sending a response
|
||
back. Examples: turn on debug event logging for the PIC, or set IPS to
|
||
1.5million. Others kinds of messages go from bochs to the control panel.
|
||
Example: errors such as "disk image not found", status information such as the
|
||
current CPU state.
|
||
|
||
But because of the nature of a control panel, most information flows from
|
||
the control panel to Bochs. I think we can take advantage of this to
|
||
simplify the protocol. The GUI can ask bochs to do things and get a
|
||
response back. Bochs can tell the GUI something, but will not get a
|
||
response back.
|
||
|
||
The control panel should exist before the Bochs simulator starts, so that the
|
||
user can get their settings right before booting up a simulator. Once
|
||
bochs has begun, some settings can no longer be changed, such as how much
|
||
memory there is. Others can be changed at any time, like the value of IPS
|
||
or the name of the floppy disk images. If you had the bochs simulator
|
||
as a shared library, the GUI could let you choose which version of the
|
||
simulator library to load (one with debugging or SMP support or not,
|
||
for example).
|
||
|
||
When the control panel connects to Bochs, each needs to learn what the other
|
||
can do. Some versions of Bochs will have cdrom support, others will not.
|
||
Design a simple and general way for the two parties to describe what they
|
||
can do, so that the GUI can grey-out some menu choices, and Bochs knows
|
||
what the GUI can handle. I think Bochs should provide a list of
|
||
capabilities in something like the form of:
|
||
typedef struct { Bit16u id; String name; } bx_capability_t;
|
||
Only the negotiation of capabilities uses the string name, and for everything
|
||
else the 16-bit id is used (use htons() if sending over network). Each
|
||
capability is like a function that can be called on the remote object,
|
||
and each function needs an input list and a return value.
|
||
|
||
Hmm.... This sounds like reinventing function calls. Next I'm going to
|
||
say we need to implement prototypes and type checking. Why not just
|
||
write a compiler!
