/*
* 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
* allow legacy memory regions to be redefined by the guest as GMRs.
*
* Using the guest framebuffer (GFB) at BAR1 for general purpose DMA
* is being phased out. Please try to use user-defined GMRs whenever
* possible.

/*
* 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.

*
* 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.

* This command sets a piece of SVGA device state called the

* format of an image in guest memory or in BAR1. The GMRFB has
* an arbitrary size, and it doesn't need to match the geometry
* of the GFB or any screen object.
*
* The GMRFB can be redefined as often as you like. You could
* always use the same GMRFB, you could redefine it before
* rendering from a different guest screen, or you could even
* redefine it before every blit.
*
* There are multiple ways to use this command. The simplest way is
* to use it to move the framebuffer either to elsewhere in the GFB
* (BAR1) memory region, or to a user-defined GMR. This lets a
* driver use a framebuffer allocated entirely out of normal system
* memory, which we encourage.
*
* Another way to use this command is to set up a ring buffer of
* updates in GFB memory. If a driver wants to ensure that no
* frames are skipped by the SVGA device, it is important that the
* driver not modify the source data for a blit until the device is
* done processing the command. One efficient way to accomplish
* this is to use a ring of small DMA buffers. Each buffer is used
* for one blit, then we move on to the next buffer in the
* ring. The FENCE mechanism is used to protect each buffer from
* re-use until the device is finished with that buffer's
* corresponding blit.
*
* This command does not affect the meaning of SVGA_CMD_UPDATE.
* UPDATEs always occur from the legacy GFB memory area. This
* command has no support for pseudocolor GMRFBs. Currently only
* true-color 15, 16, and 24-bit depths are supported. Future
* devices may expose capabilities for additional framebuffer
* formats.

* this command at least once before performing any blit from the
