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

931 * The data consists of 1 bpp AND mask followed by 32 bpp XOR (color) mask.
932 *
933 * For pointers without alpha channel the XOR mask pixels are 32 bit values: (lsb)BGR0(msb).
934 * For pointers with alpha channel the XOR mask consists of (lsb)BGRA(msb) 32 bit values.
935 *
936 * Guest driver must create the AND mask for pointers with alpha channel, so if host does not
937 * support alpha, the pointer could be displayed as a normal color pointer. The AND mask can
938 * be constructed from alpha values. For example alpha value >= 0xf0 means bit 0 in the AND mask.
939 *
940 * The AND mask is 1 bpp bitmap with byte aligned scanlines. Size of AND mask,
941 * therefore, is cbAnd = (width + 7) / 8 * height. The padding bits at the
942 * end of any scanline are undefined.
943 *
944 * The XOR mask follows the AND mask on the next 4 bytes aligned offset:
945 * uint8_t *pXor = pAnd + (cbAnd + 3) & ~3
946 * Bytes in the gap between the AND and the XOR mask are undefined.
947 * XOR mask scanlines have no gap between them and size of XOR mask is:
948 * cXor = width * 4 * height.
949 ****
950 *
951 * Preallocate 4 bytes for accessing actual data as p->au8Data.
