7972e2dade dri2: Register the DRI2DrawableType after server regeneration
The Resource database is reset upon regeneration and so the dri2 module
needs to re-register its RESTYPE for the drawable or else it will
clobber the next unsuspecting user of the database. Fortunately, DRI2 is
loaded late in the initialisation sequence and was last up until
xf86-video-intel started using the Resource database to track
outstanding swaps...

4dc5b6ea9f xfree86: Fix powerpc build with -Werror=int-to-pointer-cast -Werror=pointer-to-int-cast
memType is a uint64_t on powerpc. Using memType only really makes
sense for *physical* addresses, which can be 64-bit for 32-bit
systems running on 64-bit hardware.

However, unmapVidMem() only deals with *virtual* addresses, which
are guaranteed to fit into an uintptr_t.

34bb83b9df dix: block signals when closing all devices
When closing down all devices, we manually unset master for all attached
devices, but the device's sprite info still points to the master's sprite
info. This leaves us a window where the master is freed already but the
device isn't yet. A signal during that window causes dereference of the
already freed spriteInfo in mieqEnqueue's EnqueueScreen macro.

Simply block signals when removing all devices. It's not like we're really
worrying about high-responsive input at this stage.

89626304ea xf86Crtc: handle no outputs with no modes harder.
If you started an X server with no connected outputs, we pick a default
1024x768 mode, however if you then ran an xvidmode using app against that
server it would segfault the server due to not finding any valid modes.

This was due to the no output mode set code, only adding the modes to the
scrn->modes once, when something called randr 1.2 xf86SetScrnInfoModes would
get called and remove all the modes and we'd end up with 0.

This change fixes xf86SetScrnInfoModes to always report a scrn mode of at
least 1024x768, and pushes the initial configuration to just call it instead
of setting up the mode itself.

Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=746926

I've seen other bugs like this on other distros so it might also actually fix them.

82445286d5 Fix drain_console unregistration
Bug introduced by 9dca441670
xfree86: add a hook to replace the new console handler.

console_handler was not being set, making the server eat up CPU spinning
in WaitForSomething selecting consoleFd over and over again, every time
trying to unregister drain_console without success due to
console_handler being NULL.

Let's just fix the unregistration in xf86SetConsoleHandler() and use that.

But wait, there could be a catch: If some driver replaced the handler using
xf86SetConsoleHandler(), the unregistration in xf86CloseConsole will unregister
that one. I don't understand Xorg well enough to know whether this poses a
problem (could mess up driver deinit somehow or something like that). As it is,
xf86SetConsoleHandler() doesn't offer any way to prevent this (i.e. check which
handler is currently registered).

I had been using it for two days on my machine that previously hit 100% CPU
several times a day. That has now gone away without any new problems appearing.

d780c6f630 composite: Update borderClip in compAllocPixmap()
Previously the parent constrained borderClip was copied over
when compRedirectWindow() is called. That is insufficient eg. in
case the window was already redirected, but not yet realized. So
copy the borderClip over in compAllocPixmap() instead.

Example:
Window 1 is below an automatically redirect window 2. Window 2 is
unmapped and moved outside the extents of window 1. Window 2 is
then mapped again, and MarkOverlappedWindows() uses the up to
date borderSize of window 2 to mark windows, which leaves
window 1 unmarked. Then exposures are calculated using the stale
borderClip of window 2, which causes the window below window 2,
to be exposed through an apparent hole in window 1.

bbe6a69da3 dix: don't XWarpPointer through the last slave anymore (#38313)
This line was introduced pre-1.6 to fix Bug 19297. The effect of warping
through the VCP then was that if a device had custom valuator ranges, the
warp position would be wrong. The better device for this effect is the the
XTest device.

This fixes a server crash where the lastSlave is a pointer device without
valuators (Bug 38313#0).

And while we're at it, make sure the Xinerama code-path does the same.

4ad271d06c xfree86: Bump extension ABI version to 6.0
The video driver ABI was bumped to 11.0 in commit
0de7cec907 because of a change to the
size of ATOM in commit 51f353d0a0.  This
also affects extension modules, so the extension ABI version should
have been bumped too.

e32cc0b4c8 fb: Fix memcpy abuse
The memcpy fast path implicitly assumes that the copy walks
left-to-right.  That's not something memcpy guarantees, and newer glibc
on some processors will indeed break that assumption.  Since we walk a
line at a time, check the source and destination against the width of
the blit to determine whether we can be sloppy enough to allow memcpy.
(Having done this, we can remove the check for !reverse as well.)

On an Intel Core i7-2630QM with an NVIDIA GeForce GTX 460M running in
NoAccel, the broken code and various fixes for -copywinwin{10,100,500}
gives (edited to fit in 80 columns):

1: Disable the fastpath entirely
2: Replace memcpy with memmove
3: This fix
4: The code before this fix

  1            2                 3                 4           Operation
------   ---------------   ---------------   ---------------   ------------
258000   269000 (  1.04)   544000 (  2.11)   552000 (  2.14)   Copy 10x10
 21300    23000 (  1.08)    43700 (  2.05)    47100 (  2.21)   Copy 100x100
   960      962 (  1.00)     1990 (  2.09)     1990 (  2.07)   Copy 500x500

So it's a modest performance hit, but correctness demands it, and it's
probably worth keeping the 2x speedup from having the fast path in the
first place.
