b435e2aac1 DRI2: Expose API to set drawable swap limit.
This allows ddx to set swap_limit if there is more than one back
buffer for drawable. Setting swap_limit has to also check if change
affects a client that is blocked.

This can be used to implement N-buffering in driver with minimal
logic in allocation and selecting next back.

86f8da0aa7 DRI2: Add ReuseBufferNotify hook
ReuseBufferNotify hook is called whenever old buffer is reused in DRI2

Driver can use this hook to rewrite the buffer name if hardware requires

framebuffer that is preallocated in boot.

2f47433fef print DisplayMode type bits
Dear,

A patch I posted on xorg-devel was reviewed and is ready for
inclusion in xserver.  Would you be willing to apply the patch so that
it finds its way into the master branch ?

Thank you, Servaas Vandenberghe.

This patch adds printing of the DisplayMode type bits to
xf86PrintModeline().  It helps to trace the modeline origin and to
understand the initial configured modeline.

f51e42f583 Terminate the log with one last message.
Instead of just closing the log when everything is done, put one more
message in stating that we're actually terminating. Users or scripts that
look at the Xorg.log will then know that a) the server has terminated
properly and b) why the server terminated (to some degree, given that most
real-world errors will be caused by AbortServer()).

3798dd379c Initialize the fd to -1 for xorg.conf input devices.
For hotplugged devices, xf86AllocateInput does that for us but the xorg.conf
path is different. Since not all drivers reset the fd during PreInit but may
still call close(pInfo->fd) in all cases, this can terminate the logging
early.

Reproducible: add a wacom driver InputDevice section with no Option Device.

f0d7e9db28 xfree86: duplicate xorg.conf device information before xf86NewInputDevice
xf86ConfigLayout.inputs contains the information from the xorg.conf
file. Passing this into xf86NewInputDevice means the device will get
cleaned up on exit and the pointers in xf86ConfigLayout.inputs are left
dangling. In the second server generation, this results in a server
crash.

Also, rename pDev to pInfo. pDev is pretty much reserved for DeviceIntPtr
types.

Reproducible: AutoAddDevices off and xorg.conf input sections, trigger
server regeneration.

7d2543a3cb XKB: Add debug key actions for grabs & window tree
Add four new private XKB actions for debugging:
    * PrGrbs: print active grabs to the log file
    * Ungrab: ungrab all currently active grabs
    * ClsGrb: kill clients with active grabs
    * PrWins: dump the current window tree to the log file

To use these, you need to modify your XKB maps, e.g. the following to
have Ctrl+Alt+(F9-F12) mapped to the above:
 - compat/xfree86:
    interpret XF86LogGrabInfo {
        action = Private(type=0x86, data="PrGrbs");
    };
    interpret XF86Ungrab {
        action = Private(type=0x86, data="Ungrab");
    }
    interpret XF86ClearGrab {
        action = Private(type=0x86, data="ClsGrb");
    }
    interpret XF86LogWindowTree {
        action = Private(type=0x86, data="PrWins");
    }

 - symbols/pc:
    key <FK09> {        type="CTRL+ALT", [ Return, XF86LogGrabInfo      ]   };
    key <FK10> {        type="CTRL+ALT", [ Return, XF86Ungrab           ]   };
    key <FK11> {        type="CTRL+ALT", [ Return, XF86ClearGrab        ]   };
    key <FK12> {        type="CTRL+ALT", [ Return, XF86LogWindowTree    ]   };

At the moment, this only works if the grabbing client continues to call
AllowEvents, as the server does no event processing at all when a device
is frozen.

163441fe53 xfree86: Remove libxorg convenience library to speed up build
libxorg.la served to collect all the Xorg convenience libraries into one
massive archive to link into Xorg. This made things easy for symbol
resolution, but it tremendously slowed down the build since each change
caused libxorg.la to be rebuilt. This is an extremely slow process of
extracting all the objects from the sub-libraries and recombining them.

Instead, the archives are linked directly into Xorg. The order of the
libraries had to be tweaked a bit to make symbols resolve correctly with
the lower level code moving later in the link command.

As a side effect, since the dtrace objects are now being linked
directly into Xorg, we don't need the SPECIAL_DTRACE_OBJECTS hack to
add them twice.

 	Option "XkbLayout" "us"
 	Option "XkbOptions" "terminate:ctrl_alt_bksp"
EndSection

It disables auto keyboard configuration for layouts "GeForce" and "Matrox".
Note that "" in patterns means "no Layout sections found", e.g.
 	MatchLayout "GeForce|"
is "in layout GeForce or without explicit layout at all".

c5a612fc18 configure: Let configure --enable/disable-aiglx control building of AIGLX for all DDXs
Let configure --enable/disable-aiglx control building of AIGLX for all DDXs. Currently
we can't use --enable/disable-aiglx to control if Xwin DDX is built with AIGLX enabled,
as at the moment it's forced off if we aren't building the X.Org DDX DRI or DRI2 loader

Rearrange things a bit, introducing a new automake conditional, AIGLX_DRI_LOADER to
specifically indicate if the X.Org DDX DRI/DRI2 loader convenience library should be
built, and replace the previous X.Org DDX-specific uses of the AIGLX conditional with that

As before, AIGLX_DRI_LOADER is only enabled if --enable-glx, --enable-aiglx and at least one
of --enable-dri or --enable-dri2 are enabled

This allows the general conditional AIGLX to control if AIGLX is built for the XWin DDX as
well

The C #define AIGLX set by AC_DEFINE(AIGLX) seems to be obsolete, I can't find anything
which checks it

Updated for ajax's "glx: Make --disable-dri not disable AIGLX" patch, which allows DRI2
to be enabled independently of DRI1

88c4622b59 linux: Retry VT ioctls while errno == EINTR
When the smart scheduler is enabled, the VT ioctls (particularly
VT_WAITACTIVE) can be interrupted by the smart scheduler's SIGALRMs.
Previously, this caused the server to immediately continue on to
ScreenInit, almost certainly causing a crash or failure because the X
server that owned the VT hadn't finished cleaning up.  As of commit
7ee965a300, it causes a FatalError
instead.

Retrying the ioctl as long as it fails with errno == EINTR fixes the
problem and allows server regenerations to trigger VT switches that
actually succeed.

82498e3c2c xfree86: xv: set pointers to NULL in xf86XVFreeAdaptor
As a good practice and for eventual double frees.

The reason of this patch is due the resilience of xf86XVInitAdaptors, where
for any adaptor failure it's able to keep trying registering the following
ones.

I discussed briefly with Pauli and Ville about a bigger refactoring of such
function, doing it in a way to return instantly when a failure happens; after
all that's how mostly of the other driver functions work. Instead, we just
thought that xf86XVInitAdaptors is wise and cool, and eventually other driver
functions should be even following the main idea of resilience.

81414c1c83 xfree86: xv: fix double free in xf86XVFreeAdaptor
When xf86XVFreeAdaptor is called more than once in xf86XVInitAdaptors (it may,
but not often), the conditional being changed in this patch will always take
true path and will keep freeing pAdaptor->pAttributes, thus letting the system
error-prone.

This patch fix such problem checking for a pointer instead the number of
attributes. Such pointer will be deallocated when xf86XVFreeAdaptor is called
first and will not let the code re-run in the following calls. This is a bit
similar how the surroundings code is already doing.
