The code in hw/xfree86/os-support/bus/sparcPci.c:simbaCheckBus()
is trying to mimmick VGA routing by disabling I/O space responses
behind the Simba PCI-PCI controller.
Unfortunately, doing this also happens to disable access to the
IDE controller I/O space registers, thus crashing the system. The
granularity of the I/O disabling in the Simba controller is not
fine enough to disable VGA without also disabling the IDE controller
registers.
When the modules section is parsed, if a module is set to be loaded by
default, this will be logged. If it is redundantly specified in xorg.conf,
this will also be noted. None of this logging will happen if the xorg.conf
lacks a modules section.
This provides a new option, UseDefaultFontPath. This option is enabled by
default, and causes the X server to always append the default font path
(defined at compile time) to the font path for the server. This will allow
people to specify additional font paths if they want without breaking
their font path, thus hopefully avoiding ye olde "fixed front" problem.
Because this option is a ServerFlag option, the ServerFlags need to be
processed before the files section of the config file, so swap the order
that they are processed.
Provide default modules that may be overrided easily. Previously the
server would load a set of default modules, but only if none were
specified in the xorg.conf, or if you didn't have a xorg.conf at all. This
patch provides a default set and you can add only the "Load" instructions
to xorg.conf that you want without losing the defaults. Similarly, if you
don't want to load a module that's loaded by default, you can add "Disable
modulename" to your xorg.conf (see man xorg.conf in this release for
details). This allows for a minimal "Modules" section, where the user only
need specify what they want to be different. See bug #10541 for more.
The list of default modules is taken from the set loaded by default when
there was a xorg.conf containing no "Modules" section.
A potential problem for some users is that some users disable a module,
most notably DRI, by commenting out the "Load" line in their xorg.conf.
This needs to be changed to an uncommented "Disable" line, as DRI is
loaded by default.
Formerly we sized an array with a compile time constant, then initialized
its size to the same constant, but the Linux PCI init code would increase
that "constant". So if you happened to have more than 128 PCI devices,
you'd happily scribble into whatever variables happened to be in .bss
after that array.
Only really fixed for Linux atm. Other OSes will simply (still) fail to
work on video devices above the 128th PCI device.
SourceValidate is used exclusively by the software cursor code to pull the
cursor off of the screen before using the screen as a source operand. This
eliminates the software cursor from the frame buffer while painting the
rotated image though. Disabling this function by temporarily setting the
screen function pointer to NULL causes the cursor image to be captured.

Setting a mode on an unrotated CRTC was causing all of the rotation updates
to be disabled; the loop looking for active rotation wasn't actually looking
at each crtc, it was looking at the modified crtc many times.

Option "Enable" "True" will force the server to enable an output at startup
time, even if the output is not connected. This also causes the default
modes to be added for this output, allowing even sync ranges to be used to
pick out standard modes.
(cherry picked from commit a3d73ba2cb)
By default, use the screen monitor section for output 0, however, a driver
can change which output gets the screen monitor by calling
xf86OutputUseScreenMonitor.

The entity (device) has a locking SAREA and a master file descriptor
that optionally isn't closed between server generation.
The locking SAREA contains the device hardware lock.
Each DRI screen creates an new SAREA containing the drawable lock,
drawable-and private info, the drawable SAREA.
The first screen optionally shares its drawable SAREA with the
device SAREA.
Default is to close the master descriptor between server generations,
and to share the drawable SAREA of the first screen with the device locking
SAREA. Thus we should (hopefully) have full backwards compatibility.
Mesa changes to support single-device multiple screens are pending.
This Acer monitor reports support for 75hz refresh via EDID, and yet when
that rate is delivered, the monitor does not sync and reports out of range.
Use the existing 60hz quirk for this monitor.
(cherry picked from commit 1328a288e9)
By the time CloseScreen gets called, we can't call ProcessInputEvents, as
the event queue will get unhappy. So just unregister our hooks instantly,
and hope that they don't get called.
xf86SetSingleMode tries to resize all crtcs to match the selected mode. When
a CRTC has no matching mode, it now disables the CRTC (instead of crashing).
Also, poke the RandR extension when xf86SetSingleMode is done so that
appropriate events can be delivered, and so that future RandR queries return
correct information.
(cherry picked from commit dc6c4f6989)
/sys/devices reflects the bus topology, and we don't care that much.
Easier (and more reliable) to just look in /sys/bus/pci/devices, which
is a flat view.
When we see an evdev or vmmouse section, assume that it's a mouse, and
don't add a default mouse device. This will break users who have an
evdev keyboard section but no mouse, and want the mouse to get added
by default.
Now, fbcmap_mi.c contains the fb functions which just wrap mi functions.
Previously, these were in fbcmap.c and compiled when XFree86Server was defined.
Now, clients of fbcmap should either use fbcmap.c or fbcmap_mi.c and not worry
about setting the XFree86Server symbol.
Additionally, protect libcw setup behind checks for Render, to avoid
segfaulting if Render isn't available (xnest).
The previous setup was an ABI-preserving dance, which is better nuked now.
Now, anything that needs libcw must explicitly initialize it, and
miDisableCompositeWrapper (previously only called by EXA and presumably binary
drivers) is gone.
