.TH VMWARE __drivermansuffix__ __vendorversion__
.SH NAME
vmware \- VMware SVGA video driver
.SH SYNOPSIS
.nf
.B "Section \*qDevice\*q"
.BI "  Identifier \*q"  devname \*q
.B  "  Driver \*qvmware\*q"
\ \ ...
.B EndSection
.fi
.SH DESCRIPTION
.B vmware 
is an __xservername__ driver for VMware virtual video cards. 
.SH MODESETTING, XINERAMA AND RANDR12
If the driver can connect to the \*qvmwgfx\*q kernel module on linux, it
will attempt to use kernel modesetting and will then also use RandR12 for
multiple output operation instead of Xinerama. The X server log or the
\*qxrandr\*q application can be used to determine whether RandR12 or Xinerama
is actually used.
.SH 3D ACCELERATION
If the driver can connect to the \*qvmwgfx\*q kernel module on linux, and
the Virtual Machine is set up to use 3D acceleration, the driver will try to
use Gallium3D XA to accelerate 3D operations. It will also by default enable
DRI, the Direct Rendering Infrastructure, primarily for accelerated OpenGL.
If 3D acceleration is available,
the driver will in addition provide an additional XVideo adaptor for textured
video. Gallium3D XA,\*libxatracker.so\*q and the accelerated OpenGL driver,
\*qvmwgfx_dri.so\*q is provided by the mesa distribution.
.SH CONFIGURATION DETAILS
Please refer to __xconfigfile__(__filemansuffix__) for general configuration
details.  This section only covers configuration details specific to this
driver.
.PP
The driver auto-detects the version of any virtual VMware SVGA adapter.
.PP
The following driver
.B Options
are supported:
.TP
.BI "Option \*qHWCursor\*q \*q" boolean \*q
Enable or disable the HW cursor.  Default: off.
.TP
.BI "Option \*qXinerama\*q \*q" boolean \*q
Disable or enable Xinerama support. Default: xinerama is enabled if the
hardware supports it.
.TP
.BI "Option \*qStaticXinerama\*q \*q" string \*q
Provide a static xinerama geometry that will be active at server startup
and will not be overridden at runtime.
The format is "Width1xHeight1+Xoffset1+Yoffset1;Width2xHeight2+Xoffset2+Yoffset2" and so on. Negative offsets are not supported. If the driver is using
RandR12, this option should be used to place and enable outputs at driver
startup time or else when VMware tools is not used for that purpose.
Also please see option \*qGuiLayout\*q.
.TP
.BI "Option \*qGuiLayout\*q \*q" string \*q
A synonym to option \*qStaticXinerama\*q, since the latter name is somewhat
misleading when RandR12 is favoured before Xinerarma.
.TP
.BI "Option \*qAddDefaultMode\*q \*q" boolean \*q
Provide a default mode with a resolution identical to the resolution of the
guest before the X server was started. The X server will thus try to start
without changing resolution. Default: on.
.TP
.BI "Option \*qRenderAccel\*q \*q" boolean \*q
Try to accelerate render operations if the operations are reading from
previously accelerated contents (3D or video). This option is needed for
3D support. Default: on if 3D acceleration is supported. Otherwise off.
.TP
.BI "Option \*qDRI\*q \*q" boolean \*q
Enable the Direct Rendering Infrastructure. Default: on if 3D acceleration is
supported and \*qRenderAccel\*q is enabled. Otherwise off.
.TP
.BI "Option \*qDirectPresents\*q \*q" boolean \*q
Speed up OpenGL swapbuffers by skipping a copy operation. This provides some
OpenGL swapbuffer speedups, but may cause performance
degradation and rendering errors when 3D contents is read back for mixing
with software rendered contents. Default: off.
.TP
.BI "Option \*qHwPresents\*q \*q" boolean \*q
This is a developer convenience option and should not be used by distros
or normal users. When enabled, it copies software rendered contents to a
3D surface before presenting it, so that the visible screen is always present
on a 3D surface. Default: off.
.TP
.BI "Option \*qRenderCheck\*q \*q" boolean \*q
This is a developer convenience option and should not be used by distros
or normal users. When enabled, it tries to use 3D acceleration for all
XRender operations where 3D acceleration is supported, resulting in a
considerable slowdown due to the increased number of readbacks of
accelerated contents from host to guest. This option is used to verify
that the accelerated Xrender paths works correctly with the "rendercheck"
application. Default: off.

 * During a standard saa polyFillRect, the damage region is usually the bounding

 * damage region, we need to read all of it back first, even if the fill operation
 * itself doesn't read anything. This version of polyFillRect improves on that by
 * only damaging the area we actually fill. If it's a non-reading fill we thus don't
 * need to read back anything, but this may come at the cost of increased dirty
 * region fragmentation. In any case, this greatly improves on the performance of
 * shaped windows on top of accelerated contents, for example unscaled OSD in xine.

 *
 * 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.

 *     Writing this register will create, delete, or redefine the GMR

 *     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.

/*
 * 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.

 *    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.

 *       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_CMD_DEFINE_GMRFB --

 *    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.

 * SVGA_CMD_REMAP_GMR2 --

 *    Remap guest memory region v2.  See the description of GMRs above.
 *
 *    This command allows guest to modify a portion of an existing GMR by
 *    invalidating it or reassigning it to different guest physical pages.
 *    The pages are identified by physical page number (PPN).  The pages
 *    are assumed to be pinned and valid for DMA operations.
 *
 *    Description of command flags:
 *
 *    SVGA_REMAP_GMR2_VIA_GMR: If enabled, references a PPN list in a GMR.
 *       The PPN list must not overlap with the remap region (this can be
 *       handled trivially by referencing a separate GMR).  If flag is
 *       disabled, PPN list is appended to SVGARemapGMR command.
 *
 *    SVGA_REMAP_GMR2_PPN64: If set, PPN list is in PPN64 format, otherwise
 *       it is in PPN32 format.
 *
 *    SVGA_REMAP_GMR2_SINGLE_PPN: If set, PPN list contains a single entry.
 *       A single PPN can be used to invalidate a portion of a GMR or
 *       map it to to a single guest scratch page.

 *    image to a rectangular region of a screen or screens.
 *
 *    This command takes an optional variable-length list of clipping
 *    rectangles after the body of the command. If no rectangles are
 *    specified, there is no clipping region. The entire destRect is
 *    drawn to. If one or more rectangles are included, they describe
 *    a clipping region. The clip rectangle coordinates are measured
 *    relative to the top-left corner of destRect.
 *
 *    This clipping region serves multiple purposes:
 *
 *      - It can be used to perform an irregularly shaped blit more
 *        efficiently than by issuing many separate blit commands.
 *
 *      - It is equivalent to allowing blits with non-integer
 *        source coordinates. You could blit just one half-pixel
 *        of a source, for example, by specifying a larger
 *        destination rectangle than you need, then removing
 *        part of it using a clip rectangle.
 *
 * Availability:
