DRI uses a non-screen block/wakeup handler which will be executed after the
screen block handler finishes. To ensure that the rotation block handler is
executed under the DRI lock, dynamically wrap the screen block handler for
rotation.
Leaving devices enabled during server startup can cause problems during the
initial mode setting in the server, especially when they are used for
different purposes by the X server than by the BIOS. Disabling all of them
before any mode setting is attempted provides a stable base upon which the
remaining mode setting operations can be built.
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.
This new function walks the composite region and calls a rectangle
compositing function on each compositing rectangle. Previously there
were buggy duplicates of this code in fbcompose.c and
miext/rootles/safealpha/safeAlphaPicture.c.
Previously, the new mode was added at the head of the list. This caused the
positional correspondence between modes and the XMesaVisuals array to be off
by one. The net result was GLX clients failing when they tried to use the
last GLX mode/visual.
We still have the problem of DRI drivers not being able to use the extra
mode/visual introduced by __glXCreateARGBConfig(). glXCreateContext fails
with BadAlloc if it's attempted. This is also the source of the often-
seen warning "libGL warning: 3D driver claims to not support visual xxx"
Look into fixing that someday...
Only migrate when appropriate. In particular, don't migrate to offscreen in the
no-fallback case as copying from system memory should usually be as fast if not
faster than DownloadFromScreen, in particular if the bits need to be uploaded
to offscreen first.
* Defer to simpler hooks in more cases (inspired by XAA behaviour).
* Move damage tracking from lower to higher level functions.
* Always migrate for fallbacks.
* Convert rects to region and use it for damage tracking.
* When possible, defer to exaFillRegion{Solid,Tiled} using converted region.
* Always migrate for fallbacks.
* Move damage tracking out of ExaCheckPolyFillRect.
* Support planemasks, different ALUs and arbitrary tile origin.
* Leave damage tracking and non-trivial fallbacks to callers.
* Always migrate for fallbacks.
This is in preparation for using these from more other functions.
