36 * The last 4096 bytes of the guest VRAM contains the generic info for all
37 * DualView chunks: sizes and offsets of chunks. This is filled by miniport.
38 *
39 * Last 4096 bytes of each chunk contain chunk specific data: framebuffer info,
40 * etc. This is used exclusively by the corresponding instance of a display driver.
41 *
42 * The VRAM layout:
43 * Last 4096 bytes - Adapter information area.
44 * 4096 bytes aligned miniport heap (value specified in the config rouded up).
45 * Slack - what left after dividing the VRAM.
46 * 4096 bytes aligned framebuffers:
47 * last 4096 bytes of each framebuffer is the display information area.
48 *
49 * The Virtual Graphics Adapter information in the guest VRAM is stored by the
50 * guest video driver using structures prepended by VBOXVIDEOINFOHDR.
51 *
52 * When the guest driver writes dword 0 to the VBE_DISPI_INDEX_VBOX_VIDEO
53 * the host starts to process the info. The first element at the start of
54 * the 4096 bytes region should be normally be a LINK that points to
55 * actual information chain. That way the guest driver can have some
56 * fixed layout of the information memory block and just rewrite
57 * the link to point to relevant memory chain.
58 *
59 * The processing stops at the END element.
60 *
61 * The host can access the memory only when the port IO is processed.
62 * All data that will be needed later must be copied from these 4096 bytes.
63 * But other VRAM can be used by host until the mode is disabled.
64 *
65 * The guest driver writes dword 0xffffffff to the VBE_DISPI_INDEX_VBOX_VIDEO
66 * to disable the mode.
67 *
68 * VBE_DISPI_INDEX_VBOX_VIDEO is used to read the configuration information
69 * from the host and issue commands to the host.
70 *
71 * The guest writes the VBE_DISPI_INDEX_VBOX_VIDEO index register, the the
72 * following operations with the VBE data register can be performed:
73 *
74 * Operation Result
75 * write 16 bit value NOP
76 * read 16 bit value count of monitors
77 * write 32 bit value sets the vbox command value and the command processed by the host
78 * read 32 bit value result of the last vbox command is returned

1034 * For pointers without alpha channel the XOR mask pixels are 32 bit values: (lsb)BGR0(msb).
1035 * For pointers with alpha channel the XOR mask consists of (lsb)BGRA(msb) 32 bit values.
1036 *
1037 * Guest driver must create the AND mask for pointers with alpha channel, so if host does not
1038 * support alpha, the pointer could be displayed as a normal color pointer. The AND mask can
1039 * be constructed from alpha values. For example alpha value >= 0xf0 means bit 0 in the AND mask.
1040 *
1041 * The AND mask is 1 bpp bitmap with byte aligned scanlines. Size of AND mask,
1042 * therefore, is cbAnd = (width + 7) / 8 * height. The padding bits at the
1043 * end of any scanline are undefined.
1044 *
1045 * The XOR mask follows the AND mask on the next 4 bytes aligned offset:
1046 * uint8_t *pXor = pAnd + (cbAnd + 3) & ~3
1047 * Bytes in the gap between the AND and the XOR mask are undefined.
1048 * XOR mask scanlines have no gap between them and size of XOR mask is:
1049 * cXor = width * 4 * height.

1052 * Preallocate 4 bytes for accessing actual data as p->au8Data.
