|

25 | *
|
---|
26 | * !Revise this! It's already incorrect!
|
---|
27 | *
|
---|
28 | * The Virtual Machine Monitor (VMM) is the core of the virtual machine. It
|
---|
29 | * manages the alternate reality; controlling the virtualization, managing
|
---|
30 | * resources, tracking CPU state, it's resources and so on...
|
---|
31 | *
|
---|
32 | * We will split the VMM into smaller entities:
|
---|
33 | *
|
---|
34 | * - Virtual Machine Core Monitor (VMCM), which purpose it is to
|
---|
35 | * provide ring and world switching, that including routing
|
---|
36 | * interrupts to the host OS and traps to the appropriate trap
|
---|
37 | * handlers. It will implement an external interface for
|
---|
38 | * managing trap handlers.
|
---|
39 | *
|
---|
40 | * - CPU Monitor (CM), tracking the state of the CPU (in the alternate
|
---|
41 | * reality) and implementing external interfaces to read and change
|
---|
42 | * the state.
|
---|
43 | *
|
---|
44 | * - Memory Monitor (MM), which purpose it is to virtualize physical
|
---|
45 | * pages, segment descriptor tables, interrupt descriptor tables, task
|
---|
46 | * segments, and keep track of all memory providing external interfaces
|
---|
47 | * to access content and map pages. (Internally splitt into smaller entities!)
|
---|
48 | *
|
---|
49 | * - IO Monitor (IOM), which virtualizes in and out I/O operations. It
|
---|
50 | * interacts with the MM to implement memory mapped I/O. External
|
---|
51 | * interfaces for adding and removing I/O ranges are implemented.
|
---|
52 | *
|
---|
53 | * - External Interrupt Monitor (EIM), which purpose it is to manage
|
---|
54 | * interrupts generated by virtual devices. This monitor provides
|
---|
55 | * an interfaces for raising interrupts which is accessible at any
|
---|
56 | * time and from all thread.
|
---|
57 | * <p>
|
---|
58 | * A subentity of the EIM is the vitual Programmable Interrupt
|
---|
59 | * Controller Device (VPICD), and perhaps a virtual I/O Advanced
|
---|
60 | * Programmable Interrupt Controller Device (VAPICD).
|
---|
61 | *
|
---|
62 | * - Direct Memory Access Monitor (DMAM), which purpose it is to support
|
---|
63 | * virtual device using the DMA controller. Interfaces must be as the
|
---|
64 | * EIM interfaces independent and threadable.
|
---|
65 | * <p>
|
---|
66 | * A subentity of the DMAM is a virtual DMA Controller Device (VDMACD).
|
---|
67 | *
|
---|
68 | *
|
---|
69 | * Entities working on a higher level:
|
---|
70 | *
|
---|
71 | * - Device Manager (DM), which is a support facility for virtualized
|
---|
72 | * hardware. This provides generic facilities for efficient device
|
---|
73 | * virtualization. It will manage device attaching and detaching
|
---|
74 | * conversing with EIM and IOM.
|
---|
75 | *
|
---|
76 | * - Debugger Facility (DBGF) provides the basic features for
|
---|
77 | * debugging the alternate reality execution.

|

102 | *

103 | * - Allocate first chunk of memory and pin it down. This block of memory
|
---|
104 | * will fit the following pieces:

105 | * - Virtual Machine Instance data. (Config, CPU state, VMM state, ++)
|
---|
106 | * (This is available from everywhere (at different addresses though)).
|
---|
107 | * - VMM Guest Context code.
|
---|
108 | * - Pluggable devices Guest Context code.
|
---|
109 | * - Page tables (directory and everything) for the VMM Guest
|
---|
110 | *
|
---|
111 | * - Setup Guest (Ring 0) part:

112 | * - Setup initial page tables (i.e. directory all the stuff).
