+ * 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.
+ */
+
+/*
+ * Special GMR IDs, allowing SVGAGuestPtrs to point to framebuffer
+ * memory as well. In the future, these IDs could even be used to

+ * FIFO Synchronization Registers
+ *
+ * This explains the relationship between the various FIFO
+ * sync-related registers in IOSpace and in FIFO space.
+ *
+ * SVGA_REG_SYNC --
+ *
+ * The SYNC register can be used in two different ways by the guest:
+ *
+ * 1. If the guest wishes to fully sync (drain) the FIFO,
+ * it will write once to SYNC then poll on the BUSY
+ * register. The FIFO is sync'ed once BUSY is zero.
+ *
+ * 2. If the guest wants to asynchronously wake up the host,
+ * it will write once to SYNC without polling on BUSY.
+ * Ideally it will do this after some new commands have
+ * been placed in the FIFO, and after reading a zero
+ * from SVGA_FIFO_BUSY.
+ *
+ * (1) is the original behaviour that SYNC was designed to
+ * support. Originally, a write to SYNC would implicitly
+ * trigger a read from BUSY. This causes us to synchronously
+ * process the FIFO.
+ *
+ * This behaviour has since been changed so that writing SYNC
+ * will *not* implicitly cause a read from BUSY. Instead, it
+ * makes a channel call which asynchronously wakes up the MKS
+ * thread.
+ *
+ * New guests can use this new behaviour to implement (2)
+ * efficiently. This lets guests get the host's attention
+ * without waiting for the MKS to poll, which gives us much
+ * better CPU utilization on SMP hosts and on UP hosts while
+ * we're blocked on the host GPU.
+ *
+ * Old guests shouldn't notice the behaviour change. SYNC was
+ * never guaranteed to process the entire FIFO, since it was
+ * bounded to a particular number of CPU cycles. Old guests will
+ * still loop on the BUSY register until the FIFO is empty.
+ *
+ * Writing to SYNC currently has the following side-effects:
+ *
+ * - Sets SVGA_REG_BUSY to TRUE (in the monitor)
+ * - Asynchronously wakes up the MKS thread for FIFO processing
+ * - The value written to SYNC is recorded as a "reason", for
+ * stats purposes.
+ *
+ * If SVGA_FIFO_BUSY is available, drivers are advised to only
+ * write to SYNC if SVGA_FIFO_BUSY is FALSE. Drivers should set
+ * SVGA_FIFO_BUSY to TRUE after writing to SYNC. The MKS will
+ * eventually set SVGA_FIFO_BUSY on its own, but this approach
+ * lets the driver avoid sending multiple asynchronous wakeup
+ * messages to the MKS thread.
+ *
+ * SVGA_REG_BUSY --
+ *
+ * This register is set to TRUE when SVGA_REG_SYNC is written,
+ * and it reads as FALSE when the FIFO has been completely
+ * drained.
+ *
+ * Every read from this register causes us to synchronously
+ * process FIFO commands. There is no guarantee as to how many
+ * commands each read will process.
+ *
+ * CPU time spent processing FIFO commands will be billed to
+ * the guest.
+ *
+ * New drivers should avoid using this register unless they
+ * need to guarantee that the FIFO is completely drained. It
+ * is overkill for performing a sync-to-fence. Older drivers
+ * will use this register for any type of synchronization.
+ *
+ * SVGA_FIFO_BUSY --
+ *
+ * This register is a fast way for the guest driver to check
+ * whether the FIFO is already being processed. It reads and
+ * writes at normal RAM speeds, with no monitor intervention.
+ *
+ * If this register reads as TRUE, the host is guaranteeing that
+ * any new commands written into the FIFO will be noticed before
+ * the MKS goes back to sleep.
+ *
+ * If this register reads as FALSE, no such guarantee can be
+ * made.
+ *
+ * The guest should use this register to quickly determine
+ * whether or not it needs to wake up the host. If the guest
+ * just wrote a command or group of commands that it would like
+ * the host to begin processing, it should:
+ *
+ * 1. Read SVGA_FIFO_BUSY. If it reads as TRUE, no further
+ * action is necessary.
+ *
+ * 2. Write TRUE to SVGA_FIFO_BUSY. This informs future guest
+ * code that we've already sent a SYNC to the host and we
+ * don't need to send a duplicate.
+ *
+ * 3. Write a reason to SVGA_REG_SYNC. This will send an
+ * asynchronous wakeup to the MKS thread.

+ *
+ * - 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

+ * actually want to read back the results of 3D rendering into
+ * system memory. (And for that, the BLIT_SCREEN_TO_GMRFB

+ *
+ * - When a screen is resized, either using Screen Object commands or
