* The last 4096 bytes of the guest VRAM contains the generic info for all
* DualView chunks: sizes and offsets of chunks. This is filled by miniport.
*
* Last 4096 bytes of each chunk contain chunk specific data: framebuffer info,
* etc. This is used exclusively by the corresponding instance of a display driver.
*
* The VRAM layout:
* Last 4096 bytes - Adapter information area.
* 4096 bytes aligned miniport heap (value specified in the config rouded up).
* Slack - what left after dividing the VRAM.
* 4096 bytes aligned framebuffers:
* last 4096 bytes of each framebuffer is the display information area.
*
* The Virtual Graphics Adapter information in the guest VRAM is stored by the
* guest video driver using structures prepended by VBOXVIDEOINFOHDR.
*
* When the guest driver writes dword 0 to the VBE_DISPI_INDEX_VBOX_VIDEO
* the host starts to process the info. The first element at the start of
* the 4096 bytes region should be normally be a LINK that points to
* actual information chain. That way the guest driver can have some
* fixed layout of the information memory block and just rewrite
* the link to point to relevant memory chain.
*
* The processing stops at the END element.
*
* The host can access the memory only when the port IO is processed.
* All data that will be needed later must be copied from these 4096 bytes.
* But other VRAM can be used by host until the mode is disabled.
*
* The guest driver writes dword 0xffffffff to the VBE_DISPI_INDEX_VBOX_VIDEO
* to disable the mode.
*
* VBE_DISPI_INDEX_VBOX_VIDEO is used to read the configuration information
* from the host and issue commands to the host.
*
* The guest writes the VBE_DISPI_INDEX_VBOX_VIDEO index register, the the
* following operations with the VBE data register can be performed:
*
* Operation Result
* write 16 bit value NOP
* read 16 bit value count of monitors
* write 32 bit value sets the vbox command value and the command processed by the host
* read 32 bit value result of the last vbox command is returned
