-.SH DESCRIPTION
-The
-.B XFree86-DGA
-extension is an X server extension for allowing client programs direct
-access to the video frame buffer. This is a brief description of the
-programming interface for version 2.0 of the
-.B XFree86-DGA
-extension.
-.PP
-.B XFree86-DGA
-is not intended as a direct rendering API, but rather, as a mechanism
-to "get the X Server out of the way" so that some other direct rendering
-API can have full access to the hardware. With this in mind, DGA does
-provide clients some direct access to the hardware without requiring a
-separate rendering API, but this access is limited to direct linear
-framebuffer access.
-.PP
-Most of the reasons for the
-.B XFree86-DGA
-extension's existence are now better served in other ways. Further
-development of this extension is not expected, and it may be deprecated
-in a future release. The features that continue to be useful will either
-be provided through other existing mechanisms, or through an extension
-that address those needs more specifically.
-.PP
-.B XFree86-DGA
-is initialized by passing a number corresponding to a valid
-.I XDGAMode
-to
-.BR XDGASetMode ().
-Clients can get a list of valid modes from
-.BR XDGAQueryModes ().
-Each
-.I XDGAMode
-corresponds to a different framebuffer layout.
-.PP
-.BR XDGAQueryModes ()
-returns a pointer to an array of
-.IR XDGAMode s
-which are valid for the given screen.
-.I num
-is the number of elements in the array. The returned array can be freed
-with XFree(3). The
-.I XDGAMode
-structure is as follows:
-.PP
-.nf
-.ta .5i 2i
-typedef struct {
- int num;
- char *name;
- float verticalRefresh;
- int flags;
- int imageWidth;
- int imageHeight;
- int pixmapWidth;
- int pixmapHeight;
- int bytesPerScanline;
- int byteOrder;
- int depth;
- int bitsPerPixel;
- unsigned long redMask;
- unsigned long greenMask;
- unsigned long blueMask;
- short visualClass;
- int viewportWidth;
- int viewportHeight;
- int xViewportStep;
- int yViewportStep;
- int maxViewportX;
- int maxViewportY;
- int viewportFlags;
- int reserved1;
- int reserved2;
-.br
-} XDGAMode;
-.fi
-.TP 8
-.I num
-A unique identifying number
-.RI ( num
-> 0) for the mode. This is the number referenced when initializing the mode.
-.TP 8
-.I name
-The name of the corresponding modeline as given in the __xconfigfile__ file.
-.TP 8
-.I verticalRefresh
-The vertical refresh rate for the modeline (in Hz).
-.TP 8
-.I flags
-Any of the following may be OR'd together:
-.RS 8
-.TP 4
-.B XDGAConcurrentAccess
-Indicates that concurrent client/server access to the framebuffer is
-possible. If this flag is not set it is very important to call
-.BR XDGASync ()
-before directly accessing the framebuffer if a call to
-.BR XDGAFillRectangle (),
-.BR XDGACopyArea ()
-or
-.BR XDGACopyTransparentArea ()
-or any Xlib rendering function has been made prior to such accesses.
-.TP 4
-.B XDGASolidFillRect
-Indicates that
-.BR XDGAFillRectangle ()
-is supported.
-.TP 4
-.B XDGABlitRect
-Indicates that
-.BR XDGACopyArea ()
-is supported.
-.TP 4
-.B XDGABlitTransRect
-Indicates that
-.BR XDGACopyTransparentArea ()
-is supported.
-.TP 4
-.B XDGAPixmap
-Indicates that a Pixmap will be returned when the mode is initialized.
-This means that rendering with Xlib is possible for this mode.
-.TP 4
-.B XDGAInterlaced
-.TP 4
-.B XDGADoublescan
-Indicates that the mode is an interlaced or doublescan mode.
-.RE
-.TP 8
-.I imageWidth
-.TP 8
-.I imageHeight
-The width and height of the framebuffer area accessible by the client.
-This rectangle is always justified to the upper left-hand corner.
-.TP 8
-.I pixmapWidth
-.TP 8
-.I pixmapHeight
-The width and height of the framebuffer area accessible by Xlib. This
-rectangle is always justified to the upper left-hand corner. These
-fields are only valid if the
-.B XDGAPixmap
-flag is set in the
-.I flags
-field.
-.TP 8
-.I bytesPerScanline
-The pitch of the framebuffer in bytes.
-.TP 8
-.I byteOrder
-.B MSBFirst
-or
-.BR LSBFirst .
-.TP 8
-.I depth
-The number of bits in each pixel which contain usable data.
-.TP 8
-.I bitsPerPixel
-The number of bits taken up by each pixel.
-.TP 8
-.I redMask
-.TP 8
-.I greenMask
-.TP 8
-.I blueMask
-The RGB masks. These do not apply to color-indexed modes.
-.TP 8
-.I visualClass
-.BR TrueColor ,
-.BR PseudoColor ,
-.BR DirectColor ,
-etc.
-.TP 8
-.I viewportWidth
-.TP 8

-on the screen.
-.TP 8
-.I xViewPortStep
-.TP 8
-.I yViewPortStep
-The granularity of the x,y viewport positioning possible with the
-.BR XDGASetViewport ()
-function.
-.TP 8
-.I maxViewportX
-.TP 8
-.I maxViewportY
-The maximum x and y positions possible with the
-.BR XDGASetViewport ()
-function.
-.TP 8
-.I viewportFlags
-Any of the following may be OR'd together
-.RS 8
-.TP 4
-.B XDGAFlipRetrace
-Indicates that the hardware can switch viewports during the vertical
-retrace.
-.TP 4
-.B XDGAFlipImmediate
-Indicates that the hardware can switch viewports immediately without
-waiting for the vertical retrace.
-.RE
-.PP
-.BR XDGASetMode ()
-initialises the
-.I XDGAMode
-corresponding to
-.IR num .
-To exit DGA mode and return to normal server operation, call
-.BR XDGASetMode ()
-with
-.I num
-set to zero.
-.BR XDGASetMode ()
-returns a pointer to an
-.I XDGADevice
-if successful. The XDGADevice can be freed with XFree(3). The
-.I XDGADevice
-structure is as follows:
-.PP
-.nf
-.ta .5i 2i
-typedef struct {
- XDGAMode mode;
- unsigned char *data;
- Pixmap pixmap;
-.br
-} XDGADevice;
-.fi
-.TP 8
-.I mode
-The
-.I XDGAMode
-structure, identical to the information returned by
-.BR XDGAQueryModes ().
-.TP 8
-.I data
-If direct framebuffer access is desired and possible, this field will
-contain a pointer to the mapped framebuffer memory. Generally, this
-field will be zero unless a call to
-.BR XDGAOpenFramebuffer ()
-is made prior to initialization of the mode.
-.TP 8
-.I pixmap
-If the mode supports Xlib rendering as indicated by
-.B XDGAPixmap
-in the
-.I flags
-field, this will contain a Pixmap handle suitable for passing as the
-drawable argument to Xlib functions. This field will be zero if Xlib
-rendering is not supported.
-.PP
-.BR XDGAQueryExtension ()
-checks for the presence of the extension and returns the event and error bases.
-.PP
-.BR XDGAQueryVersion ()
-returns the
-.B XFree86-DGA
-major and minor version numbers.
-.PP
-.BR XDGAOpenFramebuffer ()
-maps the framebuffer memory. The client needs sufficient privileges to be
-able to do this.
-.BR XDGAOpenFramebuffer ()
-should be called prior to initializing a DGA mode if direct framebuffer
-access is desired for that mode.
-.BR XDGAOpenFramebuffer ()
-does not need to be called if direct framebuffer access is not required.
-If the framebuffer is opened,
-.PP
-.BR XDGACloseFramebuffer ()
-should be called prior to client exit to unmap the memory.
-.PP
-.BR XDGAChangePixmapMode ()
-can be used to change between two pixmap sizes in cases where a Pixmap is
-available for Xlib rendering. The following values for the
-.I mode
-parameter are available:
-.RS 8
-.TP 4
-.B XDGAPixmapModeLarge
-The pixmap size is defined by the
-.I pixmapWidth
-and
-.I pixmapHeight
-fields in the
-.I XDGAMode
-structure. The
-.I x
-and
-.I y
-values are ignored in this case.
-.TP 4
-.B XDGAPixmapModeSmall
-The pixmap size is defined by the
-.I viewportWidth
-and
-.I viewportHeight
-fields in the
-.I XDGAMode
-structure. In this mode, the
-.I x
-and
-.I y
-values specify where in the framebuffer this pixmap rectangle is located.
-It may be placed anywhere within the Xlib renderable region described
-by the
-.I pixmapWidth
-and
-.I pixmapHeight
-fields in the
-.IR XDGAMode .
-The
-.I x
-and
-.I y
-values returned are the resultant location of the pixmap and may be
-different from the requested x,y location due to platform specific
-alignment constraints. All Xlib rendering is clipped to this pixmap
-rectangle.
-.RE
-.PP
-.BR XDGASetViewport ()
-sets the upper left-hand corner of the rectangle of framebuffer that is
-to be displayed on the screen. Not all locations may be supported by
-the hardware and requested locations will be adjusted according to the
-.I xViewPortStep
-and
-.I yViewPortStep
-fields in the
-.IR XDGAMode .
-.PP
-.I flags
-can be
-.B XDGAFlipRetrace
-or
-.B XDGAFlipImmediate
-to adjust the viewport location at the next vertical retrace or
-immediately. Values other than the supported values advertised in the
-mode's
-.I viewportFlags
-field will result in hardware-specific default behavior.
-.B XDGAFlipImmediate
-will block until the flip is completed.
-.B XDGAFlipRetrace
-will generally NOT block so it is necessary to monitor the viewport
-status with
-.BR XDGAGetViewportStatus ().
-.B XDGAFlipImmediate
-requests during pending
-.B XDGAFlipRetrace
-requests will be ignored.
-.PP
-.BR XDGAGetViewportStatus ()
-keeps track of the
-.BR XDGASetViewport ()
-requests still pending. The return value of the function will have
-consecutive bits set (LSB justified), each bit representing a pending
-viewport change. For example:
-.PP
-.nf
- while(XDGAGetViewportStatus(dpy, screen));
-.fi
-.PP
-waits for all pending viewport changes to finish.
-.PP
-.nf
- while(0x2 & XDGAGetViewportStatus(dpy, screen));
-.fi
-.PP
-waits until all but the last viewport changes have completed.
-.PP
-.BR XDGACreateColormap ()
-is similar to the Xlib function XCreateColormap(3) except that it takes
-an
-.I XDGADevice
-as an argument instead of a Window and Visual. Though XCreateColormap(3)
-may create usable colormaps in some cases,
-.BR XDGACreateColormap ()
-is the preferred method for creating colormaps in DGA since there may
-not be an advertised visual compatible with the DGA device.
-.PP
-.BR XDGAInstallColormap ()
-must be used to install colormaps in DGA mode. XInstallColormap(3) will
-not work.
-.PP
-.BR XDGASelectInput ()
-enables DGA's own event mechanism. This function is similar to
-XSelectInput(3), and all Xlib Key, Button and Motion masks are supported.
-The following DGA events are defined:
-.PP
-.nf
-.ta .5i 2i
-typedef struct {
- int type; /\(** ButtonPress or ButtonRelease + the DGA event base*/
- unsigned long serial; /\(** # or last request processed by the server */
- Display *display; /\(** Display the event was read from */
- int screen; /\(** The screen number the event came from */
- Time time; /\(** milliseconds */
- unsigned int state; /\(** key or button mask */
- unsigned int button; /\(** detail */
-.br
-} XDGAButtonEvent;
-.fi
-.PP
-.nf
-.ta .5i 2i
-typedef struct {
- int type; /\(** KeyPress or KeyRelease + the DGA event base*/
- unsigned long serial; /\(** # or last request processed by the server */
- Display *display; /\(** Display the event was read from */
- int screen; /\(** The screen number the event came from */
- Time time; /\(** milliseconds */
- unsigned int state; /\(** key or button mask */
- unsigned int keycode; /\(** detail */
-.br
-} XDGAKeyEvent;
-.fi
-.PP
-.nf
-.ta .5i 2i
-typedef struct {
- int type; /\(** MotionNotify + the DGA event base*/
- unsigned long serial; /\(** # or last request processed by the server */
- Display *display; /\(** Display the event was read from */
- int screen; /\(** The screen number the event came from */
- Time time; /\(** milliseconds */
- unsigned int state; /\(** key or button mask */
- int dx; /\(** relative pointer motion */
- int dy; /\(** relative pointer motion */
-.br
-} XDGAMotionEvent;
-.fi
-.PP
-.BR XDGAKeyEventToXKeyEvent ()
-is a helper function to translate
-.IR XDGAKeyEvent s
-into
-.IR XKeyEvent s
-suitable for use with XLookupKeysym(3).
-.PP
-.BR XDGAFillRectangle (),
-.BR XDGACopyArea (),
-and
-.BR XDGACopyTransparentArea ()
-are included with some reservation since DGA is not intended as a
-rendering API. These are merely convenience routines and are optionally
-supported. The associated flags will be set in the
-.IR XDGAMode 's
-.I flags
-field if these functions are supported. These functions will be no-ops
-otherwise. they do not provide direct access to the hardware, but are
-simply context-less operations performed by the server.
-.PP
-.BR XDGASync ()
-blocks until all server rendering to the framebuffer completes. If Xlib
-or the 3 rendering functions above are used,
-.BR XDGASync ()
-must be called before the client directly accesses the framebuffer as
-the server rendering is asynchronous with the client and may have not
-completed. This is especially important if the
-.B XDGAConcurrentAccess
-flag is not set in the
-.IR XDGAMode 's
-.I flags
-field since concurrent access by the server and client may result in a
-system lockup.
