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 -.I viewportHeight -The dimensions of the portion of the framebuffer which will be displayed -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. -.SH SEE ALSO -__xservername__(__appmansuffix__), __xconfigfile__(__filemansuffix__) -.SH AUTHORS -.B XFree86-DGA -version 2 was written by Mark Vojkovich.
