RandR matrix computations lose too much precision in fixed point;
computations using the inverted matrix can be as much as 10 pixels off.
Convert them to double precision values and pass those around. These API
changes are fairly heavyweight; the official Render interface remains fixed
point, so the fixed point matrix comes along for the ride everywhere.
Add APIs to xf86RandR12 support and randr extension to record whether the
driver supports transforms, report that value in the RRGetCrtcTransform
reply.
New RRCrtcGetTransform function in DIX that DDX can use to get the pending
transform. The DDX code should be complete; the DIX code is just a stub at
this point.
Drivers that care about crtc positions on the screen to ensure that vblank
works correctly need to be notified when crtcs are changed.
Provide a hook in the mode setting code that is invoked whenever any
configuration is done to the screen.
Use this new hook in the DRI code so that DRI clients are notified and
receive updated information.

The xfree86 server previously hat NewInputDeviceRequest and InitInput, and
both basically did the same thing. Reduce NIDR to parameter checking and use
xf86NewInputDevice from both InitInput and NIDR to actually create the device.

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.

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.

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.

Very cute, Samsung, not only do you claim to be 16cm by 9cm in the

Some BIOSes (hi XGI!) will attempt to enumerate the PCI bus by asking
for the config space of every possible device number. This despite
perfectly functional BIOS methods to enumerate the bus exactly.
If anyone can come up with an example of a bus where:
- both i/o and memory resources are addressable
- access to them can be controlled
- but they can't be controlled independently
then by all means, reinstate this logic.

The check can fail because the output from FBIOGET_VSCREENINFO is used to set
Clock in fbdev2xfree_timing(). Then in fbdevHWSetMode(), xfree2fbdev_timing()
is called which sets the pixclock based on Clock. The resulting circle results
in slight rounding errors, causing the comparision check in fbdev_modes_equal
to fail.

No point warning about missing driver hooks, that just means the person
who gave you the driver is inept. Might as well just crash. Also,
just name anonymous screens as screen%d instead of failing after the 36th
screen. Bonus points if you can figure out what the failure mode would
be on the 36th screen, and what the effective screen limit was.
There is no way this code can have been building for anyone since pciaccess
was merged. BSD and Linux were already using OS code on sparc, the only
people who could want this are Solaris, who should be using pciaccess
anyway.
