43 * The last 4096 bytes of the guest VRAM contains the generic info for all
44 * DualView chunks: sizes and offsets of chunks. This is filled by miniport.
45 *
46 * Last 4096 bytes of each chunk contain chunk specific data: framebuffer info,
47 * etc. This is used exclusively by the corresponding instance of a display driver.
48 *
49 * The VRAM layout:
50 * Last 4096 bytes - Adapter information area.
51 * 4096 bytes aligned miniport heap (value specified in the config rouded up).
52 * Slack - what left after dividing the VRAM.
53 * 4096 bytes aligned framebuffers:
54 * last 4096 bytes of each framebuffer is the display information area.
55 *
56 * The Virtual Graphics Adapter information in the guest VRAM is stored by the
57 * guest video driver using structures prepended by VBOXVIDEOINFOHDR.
58 *
59 * When the guest driver writes dword 0 to the VBE_DISPI_INDEX_VBOX_VIDEO
60 * the host starts to process the info. The first element at the start of
61 * the 4096 bytes region should be normally be a LINK that points to
62 * actual information chain. That way the guest driver can have some
63 * fixed layout of the information memory block and just rewrite
64 * the link to point to relevant memory chain.
65 *
66 * The processing stops at the END element.
67 *
68 * The host can access the memory only when the port IO is processed.
69 * All data that will be needed later must be copied from these 4096 bytes.
70 * But other VRAM can be used by host until the mode is disabled.
71 *
72 * The guest driver writes dword 0xffffffff to the VBE_DISPI_INDEX_VBOX_VIDEO
73 * to disable the mode.
74 *
75 * VBE_DISPI_INDEX_VBOX_VIDEO is used to read the configuration information
76 * from the host and issue commands to the host.
77 *
78 * The guest writes the VBE_DISPI_INDEX_VBOX_VIDEO index register, the the
79 * following operations with the VBE data register can be performed:
80 *
81 * Operation Result
82 * write 16 bit value NOP
83 * read 16 bit value count of monitors
84 * write 32 bit value sets the vbox command value and the command processed by the host
85 * read 32 bit value result of the last vbox command is returned
