Delete time-traveling multiple personality disorder from the server.
Gaetan notes:
There were a couple of drivers containing an unknown version of the
modes/parser code. This was done in server 1.2 time frame because it
was released without mode code. It was barely or not maintained
afterwards. There are currently no video drivers with a copy of the
modes code.
Most of these ifdefs were introduced in commit
a8d760f567, where Aaron wrote,
This change uses XORG_VERSION_CURRENT < 7.0 to mean "server newer

Alan explains that:
In Xorg 1.3, when we first released an Xorg server release decoupled
from the katamari release schedule. (1.0 through 1.2 were released
as part of X11R7.0 through 7.2, while 1.3 came out between X11R7.2 &

Many references to the WindowTable array already had the corresponding
screen pointer handy, which meant they usually looked like
"WindowTable[pScreen->myNum]". Adding a field to ScreenRec instead of
keeping this information in a parallel array simplifies those
expressions, and eliminates a MAXSCREENS-sized array.
Since dix uses this data, a screen private entry isn't appropriate.
xf86-video-dummy currently uses WindowTable, so it needs to be updated
to reflect this change.

Banked framebuffers are so 1990. As of 7.4 the only drivers remaining
that used this were chips, neomagic, trident, and vesa. vesa only used
it when not using shadowfb, which is broadly undesirable anyway, and no
longer uses it at all as of 2.3.0. neomagic never used it by default,
and support for it is gone in git master. The other two effectively
only ever used it for ISA chips; since ISA support is now gone from

ISA support is available.

you know the dependency better than I do so any hints are apreciated.
afaict, the screenInfo.numScreens (the check used by Xinerama) isn't
necessarily initialized at this point so we can't use the same check.

Subject: [PATCH] xfree86: if only one screen was found, disable Xinerama (#24627)
Xorg +xinerama crashes immediately due to whacky dependency between Xinerama
and RandR12. The latter doesn't initialize if Xinerama is enabled, but if
only one screen is found, Xinerama is disabled again and RandR12 tries to
access data it never initialized.
Dependency chain is:
- ProcessCommandLine sets noPanoramiXExtension to FALSE
- xf86RandR12Init() is a noop
- PanoramiXExtensionInit sets noPanoramiXExtension to TRUE
- xf86RandR12CreateScreenResources tries to use the devPrivates key it never
initialized.
This hack checks if there's only one screen at the time RandR12 is
initialized. If so, we expect Xinerama to fail anyhow so we disable it
ourselves and proceed as planned.

Make xf86 RANDR wrap the EnterVT call chain, so it can re-probe the

time that we enter our VT again). The X server should then send RR*

- Example: mode 1280x1024, panned area 1281x1024
panned_area.x2 = 1281
mode.width = 1280
If you substract 1280 from 1281, then that leaves you with one.
Which is the one pixel that you need to move to actually see the last pixel collumn.
Substracting 1 from this will consistently prevent you from seeing the right and bottom edge.
- Add active field to crtc.
- Set gamma (only) whenever a crtc becomes active.
- Check for xf86_config being NULL.
- Increase crtc abi to 3.
- A few other fixes.
- The Gamma values from the monitor section are now used during initial config.
- The old colormap system is disabled when gamma set hook is available.
- Gamma values are now persistent for the lifetime of the xserver.
- This requires no driver changes and should be driver ABI compatible.
Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.
This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)
LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.
xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).
Instead of using a separate function to notify DIX about transform changes,
add the transform to RRCrtcNotify so that the whole Crtc state changes
atomically.
Add APIs to xf86RandR12 support and randr extension to record whether the
driver supports transforms, report that value in the RRGetCrtcTransform
reply.

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.
In order to report accurate values to users of the RandR property interface,
it's sometimes necessary to ask the driver to update the value (for example
when backlight brightness changes without the server's knowledge, due to hotkey
events or direct sysfs banging).
This patch wires up the core server code with a new xf86CrtcFuncs callback,
get_property, to allow for this.
The new code is available under the RANDR_13_INTERFACE define, which in turn
depends on the RANDR_12_INTERFACE code.
over to new system.
Need to update documentation and address some remaining vestiges of
old system such as CursorRec structure, fb "offman" structure, and
FontRec privates.
xf86RandR12ScreenSetSize must protect calls to EnableDisableFBAccess with

Remove RROutputSetCrtc as it is not really necessary. All we have to do is set

The DDX code was ignoring pending properties for computing when mode setting
was required. This meant that configurations differing only in property
values would not cause the mode to be set.
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)
Yes, two changes in one commit. Sorry 'bout that.
The first change ensures that when pending property values have been
changed, a mode set to the current mode will actually do something, rather
than being identified as a no-op. In addition, the driver no longer needs to
manage the migration of pending to current values, that is handled both
within the xf86 mode setting code (to deal with non-RandR changes) as well
as within the RandR extension itself.
The second change eliminates the two-call Create/AttachScreen stuff that was
done in a failed attempt to create RandR resources before the screen
structures were allocated. Merging these back into the Create function is
cleaner.

I think master and server-1.3-branch are more in sync now.
The xf86 mode setting code was mis-using this field to try and store a
pointer to a DisplayModeRec, however, each output has its own copy of every
DisplayModeRec leaving the one in in the RRModeRec devPrivate field pointing
at a random DisplayModeRec.
Instead of attempting to rectify this, eliminating the devPrivate entirely
turned out to be very easy; the DDX code now accepts an arbitrary RRModeRec
structure and set that to the hardware, converting it on the fly to a
DisplayModeRec as needed.
(cherry picked from commit 3506b9376c)
The RandR protocol spec has several requests in support of user-defined
modes, but the implementation was stubbed out inside the X server. Fill out
the DIX portion and start on the xf86 DDX portion. It might be necessary to
add more code to the DDX to insert the user-defined modes into the output
mode list.

Screen physical size is set to a random value before the RandR code gets

(cherry picked from commit 843077f23a)
This hook is called when the DDX needs to resize the screen. The driver is
responsible for changing virtualX and virtualY, along with any other related
screen properties (devPrivate.ptr, devKind, displayWidth, etc.).
Use the size range from the crtc config instead of randrp->virtual[XY] when
reporting the min and max screen sizes to the DDX.
New modes header files required a few minor changes to be used by external
drivers, the most notable of which is the publication of the config file
parser header files.
RandR 1.0 sizeID must be computed the same way every time, so when reporting
it in the ScreenChangeNotify event, just construct the usual 1.0 data block
and use that.
subpixel geometry information can be computed by looking at the connected
outputs and finding any with subpixel geometry and using one of those for
the global screen subpixel geometry. This might be improved by reporting
None if more than one screen has information and they conflict.
