1c94c0a63ba68be1a7b2c640e70d7a06464e4fcavboxsync * The last 4096 bytes of the guest VRAM contains the generic info for all
1c94c0a63ba68be1a7b2c640e70d7a06464e4fcavboxsync * DualView chunks: sizes and offsets of chunks. This is filled by miniport.
d46ee884c41b808b239563b1978468aae12e33a2vboxsync * Last 4096 bytes of each chunk contain chunk specific data: framebuffer info,
d46ee884c41b808b239563b1978468aae12e33a2vboxsync * etc. This is used exclusively by the corresponding instance of a display driver.
d46ee884c41b808b239563b1978468aae12e33a2vboxsync * The VRAM layout:
d46ee884c41b808b239563b1978468aae12e33a2vboxsync * Last 4096 bytes - Adapter information area.
3b70c9ab3cea93ab1a771d2db319311282041382vboxsync * 4096 bytes aligned miniport heap (value specified in the config rouded up).
fe06619ae576367ff3568e6abd99fb8ad28cc73avboxsync * Slack - what left after dividing the VRAM.
d46ee884c41b808b239563b1978468aae12e33a2vboxsync * 4096 bytes aligned framebuffers:
fe06619ae576367ff3568e6abd99fb8ad28cc73avboxsync * last 4096 bytes of each framebuffer is the display information area.
d46ee884c41b808b239563b1978468aae12e33a2vboxsync * The Virtual Graphics Adapter information in the guest VRAM is stored by the
fe06619ae576367ff3568e6abd99fb8ad28cc73avboxsync * guest video driver using structures prepended by VBOXVIDEOINFOHDR.
2a229554eb081e98411c81dcdef146c35a000f80vboxsync * When the guest driver writes dword 0 to the VBE_DISPI_INDEX_VBOX_VIDEO
fe06619ae576367ff3568e6abd99fb8ad28cc73avboxsync * the host starts to process the info. The first element at the start of
fe06619ae576367ff3568e6abd99fb8ad28cc73avboxsync * the 4096 bytes region should be normally be a LINK that points to
fe06619ae576367ff3568e6abd99fb8ad28cc73avboxsync * actual information chain. That way the guest driver can have some
fe06619ae576367ff3568e6abd99fb8ad28cc73avboxsync * fixed layout of the information memory block and just rewrite
e33247bff4fddfdba92538374bcc9e2753044a38vboxsync * the link to point to relevant memory chain.
d46ee884c41b808b239563b1978468aae12e33a2vboxsync * The processing stops at the END element.
fe06619ae576367ff3568e6abd99fb8ad28cc73avboxsync * The host can access the memory only when the port IO is processed.
e33247bff4fddfdba92538374bcc9e2753044a38vboxsync * All data that will be needed later must be copied from these 4096 bytes.
fe06619ae576367ff3568e6abd99fb8ad28cc73avboxsync * But other VRAM can be used by host until the mode is disabled.
d8523ff7d948462e328eec88b602effe2e7f7080vboxsync * The guest driver writes dword 0xffffffff to the VBE_DISPI_INDEX_VBOX_VIDEO
fe06619ae576367ff3568e6abd99fb8ad28cc73avboxsync * to disable the mode.
e33247bff4fddfdba92538374bcc9e2753044a38vboxsync * VBE_DISPI_INDEX_VBOX_VIDEO is used to read the configuration information
d8523ff7d948462e328eec88b602effe2e7f7080vboxsync * from the host and issue commands to the host.
d8523ff7d948462e328eec88b602effe2e7f7080vboxsync * The guest writes the VBE_DISPI_INDEX_VBOX_VIDEO index register, the the
d8523ff7d948462e328eec88b602effe2e7f7080vboxsync * following operations with the VBE data register can be performed:
