+ BugZilla #601: Fixing makedepend choking on floating point exception
+ because CHAR_BIT is defined to __CHAR_BIT__ which is a compiler
+ intrinsic define. BugZilla #605: Fixing build on IA64 which is broken
+ due to the inclusion of the kernel header asm/page.h. Kernel headers
+ however don't work with
+ -ansi. The inclusion of asm/page.h can however savely be removed as it
+ there are plenty of other ways to determine the page size.

+------------------------------------------------------
+Quick Guide To Patching This Package For The Impatient
+------------------------------------------------------
+
+1. Make sure you have quilt installed
+2. Unpack the package as usual with "dpkg-source -x"
+3. Run the "patch" target in debian/rules
+4. Create a new patch with "quilt new" (see quilt(1))
+5. Edit all the files you want to include in the patch with "quilt edit"
+ (see quilt(1)).
+6. Write the patch with "quilt refresh" (see quilt(1))
+7. Run the "clean" target in debian/rules
+
+Alternatively, instead of using quilt directly, you can drop the patch in to
+debian/patches and add the name of the patch to debian/patches/series.
+
+------------------------------------
+Guide To The X Strike Force Packages
+------------------------------------
+
+The X Strike Force team maintains X packages in git repositories on
+git.debian.org in the pkg-xorg subdirectory. Most upstream packages
+are actually maintained in git repositories as well, so they often
+just need to be pulled into git.debian.org in a "upstream-*" branch.
+Otherwise, the upstream sources are manually installed in the Debian
+git repository.
+
+The .orig.tar.gz upstream source file could be generated this
+"upstream-*" branch in the Debian git repository but it is actually
+copied from upstream tarballs directly.
+
+Due to X.org being highly modular, packaging all X.org applications
+as their own independent packages would have created too many Debian
+packages. For this reason, some X.org applications have been grouped
+into larger packages: xutils, xutils-dev, x11-apps, x11-session-utils,
+x11-utils, x11-xfs-utils, x11-xkb-utils, x11-xserver-utils.
+Most packages, including the X.org server itself and all libraries
+and drivers are, however maintained independently.
+
+The Debian packaging is added by creating the "debian-*" git branch
+which contains the aforementioned "upstream-*" branch plus the debian/
+repository files.
+When a patch has to be applied to the Debian package, two solutions
+are involved:
+* If the patch is available in one of the upstream branches, it
+ may be git'cherry-picked into the Debian repository. In this
+ case, it appears directly in the .diff.gz.
+* Otherwise, the patch is added to debian/patches/ which is managed
+ with quilt as documented in /usr/share/doc/quilt/README.source.
+
+quilt is actually invoked by the Debian X packaging through a larger
+set of scripts called XSFBS. XSFBS brings some other X specific
+features such as managing dependencies and conflicts due to the video
+and input driver ABIs.
+XSFBS itself is maintained in a separate repository at
+ git://git.debian.org/pkg-xorg/xsfbs.git
+and it is pulled inside the other Debian X repositories when needed.
+
+The XSFBS patching system requires a build dependency on quilt. Also
+a dependency on $(STAMP_DIR)/patch has to be added to debian/rules
+so that the XSFBS patching occurs before the actual build. So the
+very first target of the build (likely the one running autoreconf)
+should depend on $(STAMP_DIR)/patch. It should also not depend on
+anything so that parallel builds are correctly supported (nothing
+should probably run while patching is being done). And finally, the
+clean target should depend on the xsfclean target so that patches
+are unapplied on clean.
+
+When the upstream sources contain some DFSG-nonfree files, they are
+listed in text files in debian/prune/ in the "debian-*" branch of
+the Debian repository. XSFBS' scripts then take care of removing
+these listed files during the build so as to generate a modified
+DFSG-free .orig.tar.gz tarball.

+.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;

+.TP 8
+.I num
+A unique identifying number
+.RI ( num

+.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

+.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

+.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.
