The DDX (xfree86 anyway) maintains its own device list in addition to the one
in the DIX. CloseDevice will only remove it from the DIX, not the DDX. If the
server then restarts (last client disconnects), the DDX devices are still
there, will be re-initialised, then the hal devices come in and are added too.
This repeats until we run out of device ids.
This also requires us to strdup() the default pointer/keyboard in
checkCoreInputDevices.
X.Org Bug 14418 <http://bugs.freedesktop.org/show_bug.cgi?id=14418>
(cherry picked from commit 6d22a9615a)
The top bit of 0xCF8 is an enable bit, not part of the domain. Sending
cycles to domain 128 instead of domain 0 is rarely the right thing to do.
(cherry picked from commit cc7c045bae)
Get rid of glcontextmodes.[ch] from build, rename __GlcontextModes to
__GLXcontext. Drop all #includes of glcontextmodes.h and glcore.h.
Drop the DRI context modes extension.
Add protocol code to DRI2 module and load DRI2 extension by default.
(cherry picked from commit c40e0b51f0)
Patch by Joe Nall.
The option goes in the "extmod" subsection.
TODO: Make it easier for extension modules to handle their own options.

The latter doesn't give you the option's value, it just tells you if
it's present in the configuration. So using Option "EXANoComposite" "false"
disabled composite acceleration.

This patch (and not setting HARDWARE_CURSOR_BIT_ORDER_MSBFIRST on big endian
platforms) fixes it for me with the radeon driver and doesn't break intel.
Correct patch this time :)
(cherry picked from commit da973e962d)
Unless we check for vtSema before calling into the CRTC and output callbacks,
we may end up trying to access video memory that no longer exists, leading to a
crash. So if we don't have vtSema, return FALSE to the caller, indicating that
we didn't do anything.
Fixes#14444.
(cherry picked from commit bee2ddf35f)
This avoids creating a dependency on -current libpciaccess for
BSD systems other than OpenBSD (which don't otherwise need it).

Actually more like in the mainline case, where the ideal mode happens to
be the very first aspect match on the first monitor. But let's not
split hairs.
(cherry picked from commit 8248537722)
The address written to 0xcf8 contains the PCI slot address to send the
config cycle to. However, we would ignore that and always send the
cycle to the device whose BIOS we were running. This breaks some
integrated graphics platforms that have explicit knowledge about the
system's host bridge, for example.
While the ScreenRec's notion of size in millimeters would get updates,
the RANDR 1.1 notion wouldn't, so your screen would appear to be square
and probably at some ludicrous DPI.
xserver and libpciaccess both need to open /dev/xf86, which can only
be opened once. I implemented pci_system_init_dev_mem() like Ian
suggested. This requires some minor changes to the BSD-specific
os-support code. Since pci_system_init_dev_mem() is a no-op on
FreeBSD this should be no problem.
i.e., don't check for the end of the list by ->name == NULL, since that
won't work now. Fix the consumers of xf86DefaultModes to use the new
explicit size as well.
Old heuristic was to find the first monitor that expressed a preference,
then attempt to get all other monitors to agree. This doesn't work
particularly well when the two sets of modes don't precisely intersect,
you get overlapping-but-not-identical output geometry and things go wrong.
New heuristic is:
- Exact user preference, if given
- Exact output preference, if the same for all outputs
- Best (largest) mode of modes common to all outputs:
- with the same aspect ratio as all outputs (may be NULL)
- with 4:3 aspect ratio
- Then the old heuristic to try to get something lit
Note that it is simply not doable to have a reliable initial output guess if
you insist on trying to clone all outputs together. It's far too easy to
end up with displays that simply don't have modes in common. We need to
switch to right-of placement someday, once we're not limited to CRTC size
limits and we have working multi-GPU in RANDR.
(cherry picked from commit 27e7dacbf7)
If you don't do this, then Modes "800x600" in the Display subsection will
be dutifully ignored and the driver will start at whatever resolution it
feels like.
