21 *
22 * !Revise this! It's already incorrect!
23 *
24 * The Virtual Machine Monitor (VMM) is the core of the virtual machine. It
25 * manages the alternate reality; controlling the virtualization, managing
26 * resources, tracking CPU state, it's resources and so on...
27 *
28 * We will split the VMM into smaller entities:
29 *
30 * - Virtual Machine Core Monitor (VMCM), which purpose it is to
31 * provide ring and world switching, that including routing
32 * interrupts to the host OS and traps to the appropriate trap
33 * handlers. It will implement an external interface for
34 * managing trap handlers.
35 *
36 * - CPU Monitor (CM), tracking the state of the CPU (in the alternate
37 * reality) and implementing external interfaces to read and change
38 * the state.
39 *
40 * - Memory Monitor (MM), which purpose it is to virtualize physical
41 * pages, segment descriptor tables, interrupt descriptor tables, task
42 * segments, and keep track of all memory providing external interfaces
43 * to access content and map pages. (Internally splitt into smaller entities!)
44 *
45 * - IO Monitor (IOM), which virtualizes in and out I/O operations. It
46 * interacts with the MM to implement memory mapped I/O. External
47 * interfaces for adding and removing I/O ranges are implemented.
48 *
49 * - External Interrupt Monitor (EIM), which purpose it is to manage
50 * interrupts generated by virtual devices. This monitor provides
51 * an interfaces for raising interrupts which is accessible at any
52 * time and from all thread.
53 * <p>
54 * A subentity of the EIM is the vitual Programmable Interrupt
55 * Controller Device (VPICD), and perhaps a virtual I/O Advanced
56 * Programmable Interrupt Controller Device (VAPICD).
57 *
58 * - Direct Memory Access Monitor (DMAM), which purpose it is to support
59 * virtual device using the DMA controller. Interfaces must be as the
60 * EIM interfaces independent and threadable.
61 * <p>
62 * A subentity of the DMAM is a virtual DMA Controller Device (VDMACD).
63 *
64 *
65 * Entities working on a higher level:
66 *
67 * - Device Manager (DM), which is a support facility for virtualized
68 * hardware. This provides generic facilities for efficient device
69 * virtualization. It will manage device attaching and detaching
70 * conversing with EIM and IOM.
71 *
72 * - Debugger Facility (DBGF) provides the basic features for
73 * debugging the alternate reality execution.
74 *
75 *
76 *
77 * @section pg_vmm_s_use_cases Use Cases
78 *
79 * @subsection pg_vmm_s_use_case_boot Bootstrap
80 *
81 * - Basic Init:
82 * - Init SUPDRV.
83 *
84 * - Init Virtual Machine Instance:
85 * - Load settings.
86 * - Check resource requirements (memory, com, stuff).
87 *
88 * - Init Host Ring 3 part:
89 * - Init Core code.
90 * - Load Pluggable Components.
91 * - Init Pluggable Components.
92 *
93 * - Init Host Ring 0 part:
94 * - Load Core (core = core components like VMM, RMI, CA, and so on) code.
95 * - Init Core code.
96 * - Load Pluggable Component code.
97 * - Init Pluggable Component code.
98 *
99 * - Allocate first chunk of memory and pin it down. This block of memory
100 * will fit the following pieces:
101 * - Virtual Machine Instance data. (Config, CPU state, VMM state, ++)
102 * (This is available from everywhere (at different addresses though)).
103 * - VMM Guest Context code.
104 * - Pluggable devices Guest Context code.
105 * - Page tables (directory and everything) for the VMM Guest
106 *
107 * - Setup Guest (Ring 0) part:
108 * - Setup initial page tables (i.e. directory all the stuff).
109 * - Load Core Guest Context code.
110 * - Load Pluggable Devices Guest Context code.
111 *
