/*
- * Capabilities
+ * Guest memory regions (GMRs):
+ *
+ * This is a new memory mapping feature available in SVGA devices
+ * which have the SVGA_CAP_GMR bit set. Previously, there were two
+ * fixed memory regions available with which to share data between the
+ * device and the driver: the FIFO ('MEM') and the framebuffer. GMRs
+ * are our name for an extensible way of providing arbitrary DMA
+ * buffers for use between the driver and the SVGA device. They are a
+ * new alternative to framebuffer memory, usable for both 2D and 3D
+ * graphics operations.
+ *
+ * Since GMR mapping must be done synchronously with guest CPU
+ * execution, we use a new pair of SVGA registers:
+ *
+ * SVGA_REG_GMR_ID --
+ *
+ * Read/write.
+ * This register holds the 32-bit ID (a small positive integer)
+ * of a GMR to create, delete, or redefine. Writing this register
+ * has no side-effects.
+ *
+ * SVGA_REG_GMR_DESCRIPTOR --
+ *
+ * Write-only.
+ * Writing this register will create, delete, or redefine the GMR
+ * specified by the above ID register. If this register is zero,
+ * the GMR is deleted. Any pointers into this GMR (including those
+ * currently being processed by FIFO commands) will be
+ * synchronously invalidated.
+ *
+ * If this register is nonzero, it must be the physical page
+ * number (PPN) of a data structure which describes the physical
+ * layout of the memory region this GMR should describe. The
+ * descriptor structure will be read synchronously by the SVGA
+ * device when this register is written. The descriptor need not
+ * remain allocated for the lifetime of the GMR.
+ *
+ * The guest driver should write SVGA_REG_GMR_ID first, then
+ * SVGA_REG_GMR_DESCRIPTOR.
+ *
+ * SVGA_REG_GMR_MAX_IDS --
+ *
+ * Read-only.
+ * The SVGA device may choose to support a maximum number of
+ * user-defined GMR IDs. This register holds the number of supported
+ * IDs. (The maximum supported ID plus 1)
+ *
+ * SVGA_REG_GMR_MAX_DESCRIPTOR_LENGTH --
+ *
+ * Read-only.
+ * The SVGA device may choose to put a limit on the total number
+ * of SVGAGuestMemDescriptor structures it will read when defining
+ * a single GMR.
+ *
+ * The descriptor structure is an array of SVGAGuestMemDescriptor
+ * structures. Each structure may do one of three things:
+ *
+ * - Terminate the GMR descriptor list.
+ * (ppn==0, numPages==0)
+ *
+ * - Add a PPN or range of PPNs to the GMR's virtual address space.
+ * (ppn != 0, numPages != 0)
+ *
+ * - Provide the PPN of the next SVGAGuestMemDescriptor, in order to
+ * support multi-page GMR descriptor tables without forcing the
+ * driver to allocate physically contiguous memory.
+ * (ppn != 0, numPages == 0)
+ *
+ * Note that each physical page of SVGAGuestMemDescriptor structures
+ * can describe at least 2MB of guest memory. If the driver needs to
+ * use more than one page of descriptor structures, it must use one of
+ * its SVGAGuestMemDescriptors to point to an additional page. The
+ * device will never automatically cross a page boundary.
+ *
+ * Once the driver has described a GMR, it is immediately available
+ * for use via any FIFO command that uses an SVGAGuestPtr structure.
+ * These pointers include a GMR identifier plus an offset into that
+ * GMR.
+ *
+ * The driver must check the SVGA_CAP_GMR bit before using the GMR
+ * registers.

+ *
+ * Provides dynamic multi-screen rendering, for improved Unity and
+ * multi-monitor modes. With Screen Object, the guest can
+ * dynamically create and destroy 'screens', which can represent
+ * Unity windows or virtual monitors. Screen Object also provides
+ * strong guarantees that DMA operations happen only when
+ * guest-initiated. Screen Object deprecates the BAR1 guest
+ * framebuffer (GFB) and all commands that work only with the GFB.
+ *
+ * New registers:
+ * FIFO_CURSOR_SCREEN_ID, VIDEO_DATA_GMRID, VIDEO_DST_SCREEN_ID
+ *
+ * New 2D commands:
+ * DEFINE_SCREEN, DESTROY_SCREEN, DEFINE_GMRFB, BLIT_GMRFB_TO_SCREEN,
+ * BLIT_SCREEN_TO_GMRFB, ANNOTATION_FILL, ANNOTATION_COPY
+ *
+ * New 3D commands:
+ * BLIT_SURFACE_TO_SCREEN
+ *
+ * New guarantees:
+ *
+ * - The host will not read or write guest memory, including the GFB,
+ * except when explicitly initiated by a DMA command.
+ *
+ * - All DMA, including legacy DMA like UPDATE and PRESENT_READBACK,
+ * is guaranteed to complete before any subsequent FENCEs.
+ *
+ * - All legacy commands which affect a Screen (UPDATE, PRESENT,
+ * PRESENT_READBACK) as well as new Screen blit commands will
+ * all behave consistently as blits, and memory will be read
+ * or written in FIFO order.
+ *
+ * For example, if you PRESENT from one SVGA3D surface to multiple
+ * places on the screen, the data copied will always be from the
+ * SVGA3D surface at the time the PRESENT was issued in the FIFO.
+ * This was not necessarily true on devices without Screen Object.
+ *
+ * This means that on devices that support Screen Object, the
+ * PRESENT_READBACK command should not be necessary unless you
+ * actually want to read back the results of 3D rendering into
+ * system memory. (And for that, the BLIT_SCREEN_TO_GMRFB
+ * command provides a strict superset of functionality.)
+ *
+ * - When a screen is resized, either using Screen Object commands or
+ * legacy multimon registers, its contents are preserved.

- * SVGA_FB_START is the default starting address of the SVGA frame
- * buffer in the guest's physical address space.
- * SVGA_FB_START_BIGMEM is the starting address of the SVGA frame
- * buffer for VMs that have a large amount of physical memory.
- *
- * The address of SVGA_FB_START is set to 2GB - (SVGA_FB_MAX_SIZE + SVGA_MEM_SIZE),
- * thus the SVGA frame buffer sits at [SVGA_FB_START .. 2GB-1] in the
- * physical address space. Our older SVGA drivers for NT treat the
- * address of the frame buffer as a signed integer. For backwards
- * compatibility, we keep the default location of the frame buffer
- * at under 2GB in the address space. This restricts VMs to have "only"
- * up to ~2031MB (i.e., up to SVGA_FB_START) of physical memory.
- *
- * For VMs that want more memory than the ~2031MB, we place the SVGA
- * frame buffer at SVGA_FB_START_BIGMEM. This allows VMs to have up
- * to 3584MB, at least as far as the SVGA frame buffer is concerned
- * (note that there may be other issues that limit the VM memory
- * size). PCI devices use high memory addresses, so we have to put
- * SVGA_FB_START_BIGMEM low enough so that it doesn't overlap with any
- * of these devices. Placing SVGA_FB_START_BIGMEM at 0xE0000000
- * should leave plenty of room for the PCI devices.
- *
- * NOTE: All of that is only true for the 0710 chipset. As of the 0405
- * chipset, the framebuffer start is determined solely based on the value
- * the guest BIOS or OS programs into the PCI base address registers.
