When the linux kernel sets the NX bit vm86 segfaults when it tries to execute
code in memory that is not marked EXEC. Such code gets called whenever
we return from a VBIOS call to signal the calling program that the call
is actually finished and that we are not trapping for other reasons (like
IO accesses).
Use mprotect(2) to set these memory ranges PROT_EXEC.
There's little chance that we'll get the input devices at runtime without HAL,
we might as well force the server to add mouse/kbd devices automatically -
just like in the olden days.

As reported in http://bugs.freedesktop.org/show_bug.cgi?id=18438
the server suggests reconfiguring HAL if AllowEmptyInput is enabled
and no input devices are known.
Instead of that notice, if HAL is disabled at configure time,
AllowEmptyInput is enabled in the config and no input devices are
found report those facts and recommend disabling AllowEmptyInput.
When using any XAAPixmapOps, we call into unknown but freshly
unwrapped callbacks (like fb ones). Unlike the XAA*Fallback calls,
we did so without syncing first, exposing us to all kinds of
synchronisation issues.
I believe that the rendering errors appeared now because *PaintWindow
vanished (e4d11e58), and we just use miPaintWindow instead. This
takes a less direct route to the hw and ends up at
PolyFillRectPixmap, which very often left drawing artifacts.
We now sync accordingly, and no longer get the rendering artifacts i
was methodically reproducing on radeonhd, radeon, unichrome...
Also, in order to allow driver authors to remove extensive syncing
or flushing to hide this issue, create XAA_VERSION_ defines, put
them in xaa.h and bump the patchlevel.
(novell bug #435791)
When setting the depth to 24, leave bpp unset so the logic to pick
a supported value is used instead of ignoring the driver's preference
and forcing 32 bpp.
Works around a silly bug in the kernel that causes wakeup storms after
too many keypresses. Should fix the kernel bug too, but this at least
keeps the idle wakeup count below 1000/sec.
When a user specifies the position of an output for which no modes exist
(for whatever reason) assume that the width and height of this output
is 0. The result will be the same as if this output isn't taken into
consideration at all and thus should be sane. It will prevent a segfault
when trying to determine the width and height of a non-existent mode.
Also merge sun_bios.c into sun_vid.c and upstream Solaris patch to
keep aperture device open, to allow mappings to occur after X server
has given up uid 0.
Maybe one day I stop doing stupid patches like
a3a7c12fcf.
So, if X < low, reset to low, and _not_ to high.
If X > high, reset to high, and _not_ to low.
This consists of two parts:
In the implicit server layout, ignore those drivers when looking for a core
device.
And after finishing the server layout, run through the list of devices and
remove any that use mouse or kbd.
AEI is mutually exclusive with the kbd and mouse drivers, so pick either - or.

The precedence of == is higher than that of &, so that code was
probably buggy.

Usually, the console is set to RAW in the kbd driver. If we hotplug all input
devices (i.e. the evdev driver for keyboards) and the console is left as-is.
As a result, the evdev driver must put an EVIOCGRAB on the device to avoid
characters leaking onto the console. This again breaks many things, amongst
them lirc, in-kernel mouse button emulation and HAL.
This patch sets the console to RAW if AllowEmptyInput is on.
Use-cases:
1. AEI is off
1.1. Only kbd driver is used - behaviour as-is.
1.2. kbd and evdev driver is used: if evdev does not grab the device,
duplicate events are generated.
2. AEI is on
2.1. Only evdev driver is used - behaviour as-is, but evdev does not need
to grab the device anymore.
2.2. evdev and kbd are used: duplicate key events are generated if evdev
does not grab the device.
1.2 is a marginal use-case that can be fixed by adding a "grab" option to the
evdev driver (update of xorg.conf is needed).
2.2 is an issue. If we have no ServerLayout section, AEI is on, but devices
specified in the xorg.conf are still added [1], resulting in duplicate events.
This is a common configuration and needs sorting out.

I've seen about one case in three years where this has actually been
correlated with the real cause of failure, and we've trained people to
freak out about X_WARNING, so let's be less alarmist.
Very cute, Samsung, not only do you claim to be 16cm by 9cm in the
global size record, you also claim to be 160mm by 90mm in the detailed
timings. Grrr.
NIDR should be used to create a new SD from e.g. within a driver.
DIDR should be used to remove a device from the server.
