As of server 1.13, systems with DRM and Udev will have BUS_PLATFORM as

Mesa doesn't ship DRI1 drivers as of 8.0, which is about 18 months and
three releases ago. The main reason to have wanted DRI1 AIGLX was to
get a GLX compositor working, but DRI1's (lack of) memory management API
meant that the cost of a GLX compositor was breaking direct GLX apps,
which isn't a great tradeoff.
Of the DRI1 drivers Mesa has dropped, I believe only mga stands to lose
some functionality here, since it and only it has support for
NV_texture_rectangle. Since that's required for every extant GLX
compositor I know of, I conclude that anybody with a savage, say, would
probably not notice AIGLX going away, since they wouldn't be running a
GLX compositor in the first place.
In the future we'd like to use GL in the server in a more natural way,
as just another EGL client, including in the GLX implementation itself.
Since there's no EGL implemented for DRI1 drivers, this would already
doom AIGLX on DRI1 (short of entirely forking the GLX implementation,
which I'm not enthusiastic about).

The former was explicitly designed to execute additional code after the binary
has been installed. The latter can be executed in any order, hence it's
current dependency on install-binPROGRAMS as a workaround.
The CYGWIN libXorg.exe.a target is an installation target rather than
a post-installation one, so it should not be done as a hook. It does not depend
on the Xorg executable being installed.
Automake:
"These hooks are run after all other install rules of the appropriate type,
exec or data, have completed. So, for instance, it is possible to perform
post-installation modifications using an install hook".
"With the -local targets, there is no particular guarantee of execution order;
typically, they are run early, but with parallel make, there is no way
to be sure of that".

Commit 8f4640bdb9 fixed a bit of a
chicken-and-egg problem by detaching GPU screens when their providers
are destroyed, which happens before CloseScreen is called. However,
this created a new problem: the GPU screen tears down its RandR crtc
objects during CloseScreen and if one of them is active, it tries to
detach the scanout pixmap then. This crashes because
RRCrtcDetachScanoutPixmap tries to get the master screen's screen
pixmap, but crtc->pScreen->current_master is already NULL at that
point.
It doesn't make sense for an unbound GPU screen to still be scanning
out its former master screen's pixmap, so detach them first when the
provider is destroyed.

The peculiar way we handle coordinates results in relative coordinates on
absolute devices being added to the last value, then that value is mapped to
the screen (taking the device dimensions into account). From that mapped
value we get the final coordinates, both screen and device coordinates.
To avoid uneven scaling on relative coordinates, they are pre-scaled by
screen ratio:resolution:device ratio factor before being mapped. This
ensures that a circle drawn on the device is a circle on the screen.
Previously, we used the ratio to scale x up. Synaptics already does its own
scaling based on the resolution and that is done by scaling y down by the
ratio. So we can remove the code from the driver and get approximately the
same behaviour here.
Minor ABI bump, so we can remove this from synaptics.

This reverts commit 3209b094a3. After a
long debug session by Paul Berry, it appears that this was the commit
that has been producing sporadic failures in piglit front buffer
rendering tests for the last several years.
GetBuffers may return fresh buffers with invalid contents at a couple
reasonable times:
- When first asked for a non-fake-front buffer.
- When the drawable size is changed, an Invalidate has been sent, and
obviously the app needs to redraw the whole buffer.
- After a glXSwapBuffers(), GL allows the backbuffer to be undefined,
and an Invalidate was sent to tell the GL that it should grab these
appropriate new buffers to avoid stalling.
But with the patch being reverted, GetBuffers would also return fresh
invalid buffers when the drawable serial number changed, which is
approximately "whenever, for any reason". The app is not expecting
invalid buffer contents "whenever", nor is it valid. Because the GL
usually only GetBuffers after an Invalidate is sent, and the new
buffer allocation only happened during a GetBuffers, most apps saw no
problems. But apps that do (fake-)frontbuffer rendering do frequently
ask the server for the front buffer (since we drop the fake front
allocation when we're not doing front buffer rendering), and if the
drawable serial got bumped midway through a draw, the server would
pointlessly ditch the front *and* backbuffer full of important
drawing, resulting in bad rendering.
The patch was originally to fix bugzilla:
https://bugs.freedesktop.org/show_bug.cgi?id=28365
Specifically:
To reproduce, start with a large-ish display (i.e. 1680x1050 on my
laptop), use the patched glxgears from bug 28252 to add the
-override option. Then run glxgears -override -geometry 640x480
to create a 640x480 window in the top left corner, which will work
fine. Next, run xrandr -s 640x480 and watch the fireworks.
I've tested with an override-redirect glxgears, both with vblank sync
enabled and disabled, both with gnome-shell and no window manager at
all, before and after this patch. The only problem observed was that
before and after the revert, sometimes when alt-tabbing to kill my
gears after completing the test gnome-shell would get confused about
override-redirectness of the glxgears window (according to a log
message) and apparently not bother doing any further compositing.
