Adam Jackson ff310903f3 mi: Add a default no-op miSourceValidate
Slightly simplifies the callers since they don't need to check for
non-NULL anymore.

I do extremely hate the workarounds here to suppress misprite taking the
cursor down though. Surely there's a better way.

Adam Jackson 0f477cc68b dix, composite: Optimize setting window backing store state
We hide CWBackingStore from the screen hook if nothing's actually
changing, which means compChangeWindowAttributes no longer needs to
compare the requested state with the present one.

Pierre Ossman 1bd5d0a53c Switch automatic composite update to WorkQueue
It is currently (ab)using the screen BlockHandler callback to do
this. But this can cause problems with other extension as their
block handlers might have executed before Composite's. And the
operations Composite does might result in them wanting to change
timeouts.

Practically this caused problems for TigerVNC's VNC extension which
failed to send out updates for Composite's screen updates.

Kristian Høgsberg 4ba7b59446 composite: Add exception mechanism for implicit redirection policy
Normally composite will decide to add implicit redirection when a
window with an alternate visual is a parent of a window with a regular
visual or vice versa.  This uses extra pixmap memory and incurs an extra
copy.  This exception mechanism provides a way for a DDX to override this
if the DDX knows that its acceleration architecture will render correctly.

The relevant case is that of an RGB window reparented into a ARGB parent
frame window.  If the DDX knows that the acceleration architecture in use
will pad the alpha channel to opaque when rendering to the RGB window,
the implicit redirection can be avoided.

This patch adds a new composite function:

  CompositeRegisterImplicitRedirectionException()

which lets a DDX register a pair of parent and child window visuals, that
will not be implicitly redirected even if the normal policy would have
made that choice.

    xf86i2c: add pscrn for drivers to use

    This just adds a pScrn pointer into the struct for the drivers to use
    instead of scrnIndex. Mostly scrnIndex is used for logging, but some
    drivers use it to lookup xf86Screens, so let them stash a pScrn instead.

    Removing the scrnIndex is a bit more involved and I'm not sure its worth
    the effort. Doing i2c in the X server is legacy code as far as I'm concerned.

Keith Packard 9838b7032e Introduce a consistent coding style
This is strictly the application of the script 'x-indent-all.sh'
from util/modular. Compared to the patch that Daniel posted in
January, I've added a few indent flags:

	-bap
	-psl
	-T PrivatePtr
	-T pmWait
	-T _XFUNCPROTOBEGIN
	-T _XFUNCPROTOEND
	-T _X_EXPORT

The typedefs were needed to make the output of sdksyms.sh match the
previous output, otherwise, the code is formatted badly enough that
sdksyms.sh generates incorrect output.

The generated code was compared with the previous version and found to
be essentially identical -- "assert" line numbers and BUILD_TIME were
the only differences found.

The comparison was done with this script:

dir1=$1
dir2=$2

for dir in $dir1 $dir2; do
	(cd $dir && find . -name '*.o' | while read file; do
		dir=`dirname $file`
		base=`basename $file .o`
		dump=$dir/$base.dump
		objdump -d $file > $dump
	done)
done

find $dir1 -name '*.dump' | while read dump; do
	otherdump=`echo $dump | sed "s;$dir1;$dir2;"`
	diff -u $dump $otherdump
done

walk to compPaintChildrenToWindow. Calling compPaintChildrenToWindow
allows an arbitrary subtree to be updated, instead of having to update
all the windows. This will be used to make sure all the descendants are
copied to the parent when the parent window contents need to be accessed
in IncludeInferios sub-window mode.

WindowRec has a new member 'damagedDescendants' that is used to keep
track of which subtrees need updating. When a window is damaged,
'damagedDescendants' will be set for all the ancestors, and when a
subtree is updated, the tree walk can be stopped early if no damaged
descendants are present.

CompScreenRec no longer needs the 'damaged' member since the root
window's 'damagedDescendants' provides the same information.

Pauli Nieminen c038b8b28e composite: Only register the block handler when it is required
Even calling block handler that doesn't do much is costly in arm. It
takes a few microseconds each time which adds up to relative high CPU
time because it is done 500+ times per second.

Simple optimization is to register the block handler only when it is
required.

Dave Airlie 82d41ada99 composite: fix freeing of old pixmap until after move/resize/cbw (bug 28345)
The fixes for the composite reallocation failure, were freeing the oldpixmap
straight after reallocating the new one, however this led to some wierd
effects in e16 compositing, and I think in a few other places. This patch
moves the freeing of the pixmap into the post wrapped stage. I'm not sure if
we are actually better off breaking ABI and adding another callback from the
ConfigureWindow to composite to make sure the old pixmap is always freed,
but this should be satisfactory as we should always hit one of the freeing
paths or else its a bug in the DIX.

Dave Airlie 959a1eaf1c composite: use config notify hook to do pixmap resize.
Since reallocating the backing pixmap can fail, we need to try and do
it before any other side effects of reconfiguring the window happen.

This changes the ConfigNotify hook to return status, and moves the
composite window reconfiguration wrappers to ConfigNotify. They all
basically did the same thing, so we can drop the MoveWindow,
ResizeWindow, ChangeBorderWidth wrappers, and allow ConfigNotify to do
all the work. If reallocation fails we fail before we send any
confiureNotify events, or enter the area we can't recover from.

The only place we now enforce 32k limits are in EXA/UXA/fb, so drivers
that don't use this should probably deal with it in their pixmap
allocate if they don't already.

This also breaks ABI, so we need an alternate fix for older servers,
working on the X server makes me realise why I'm a kernel hacker.

Jamey Sharp e7fae9ecc4 Move each screen's root-window pointer into ScreenRec.
Many references to the WindowTable array already had the corresponding
screen pointer handy, which meant they usually looked like
"WindowTable[pScreen->myNum]". Adding a field to ScreenRec instead of
keeping this information in a parallel array simplifies those
expressions, and eliminates a MAXSCREENS-sized array.

Since dix uses this data, a screen private entry isn't appropriate.

xf86-video-dummy currently uses WindowTable, so it needs to be updated
to reflect this change.

the visual resize + colormaps fixups in one place. This version
also consolidates the vid allocation for the DepthPtr inside the

I'm not 100% sure colormap.[ch] is the correct place for this but

Paulo Cesar Pereira de Andrade 49f77fff14 Rework symbol visibility for easier maintenance
Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.

  This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)

  LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.

  xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).

This was an attempt to avoid scratch gc creation and validation for paintwin
because that was expensive.  This is not the case in current servers, and the
danger of failure to implement it correctly (as seen in all previous
implementations) is high enough to justify removing it.  No performance
difference detected with x11perf -create -move -resize -circulate on Xvfb.
Leave the screen hooks for PaintWindow* in for now to avoid ABI change.

Adam Jackson ae7f71a8b3 Implement core protocol backing store exclusively in terms of Composite.
Composite's automatic redirection is a more general mechanism than the
ad-hoc BS machinery, so it's much prettier to implement the one in terms
of the other.  Composite now wraps ChangeWindowAttributes and activates
automatic redirection for windows with backing store requested.  The old
backing store infrastructure is completely gutted: ABI-visible structures
retain the function pointers, but they never get called, and all the
open-coded conditionals throughout the DIX layer to implement BS are gone.

Note that this is still not a strictly complete implementation of backing
store, since Composite will throw the bits away on unmap and therefore
WhenMapped and Always hints are equivalent.
