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.
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.
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.
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.
CVT is enough different from GTF that it should not be used on monitors
that aren't expecting it. This brings us closer to what the spec says
the correct behaviour is.
Before this it was meaningless to try to mark DisplayModeRec tables
const, since the mode name would be emitted as a pointer to an
anonymous string constant, and therefore would have to be fixed up by
ld.so and so couldn't live in .rodata. With this change the standard
mode lists can live in .rodata, and modes duplicated from them will
have their names filled in on the fly.
FindPCIVideoInfo() function isn't need anymore.
xf86scanpci() is being called only once so we don't need permanent
(static) variables there.
restorePciState() is not used for now (until we find why multiple
cards aren't working).
Formerly the code claimed it could only handle up to 256 visuals, which
was true. Also true, but not explicitly stated, was that it could only
handle visuals with VID < 256. If you have enough screens, and subsystems
that add lots of visuals, you can easily run off the end. (Made worse
because we allocate visual IDs from the same pool as XIDs.) If your app
then chooses a visual > 256, then the Xinerama code would throw BadMatch
on CreateColormap and your app wouldn't start.
With this change, PanoramiXVisualTable is gone. Other subsystems that
were using it as a translation table between each screen's visuals now
use a PanoramiXTranslateVisual() helper.
When an expose event happens on an host GL window paired with an
internal drawable, route that expose event to the clients listening
to the expose event on the internal drawable.
This reverts commit 3abce3ea2b and
6cbaf15e61.
The memory returned to xf86LoadModule was allocated in doLoadModule, which
calls the respective module's PreInit. As it turns out, input and output
drivers store a pointer to the module elswhere, so freeing it in
xf86LoadModule is a bad idea.
For further reference: hw/xfree86/common/xf86Helper.c
Input drivers: xf86InputDriverList[blah]->module = module;
Output drivers: xf86DriverList[blah]->module = module;
Unloading the module would not look pretty then.
LoadModule() returns the only reference to a fresh piece of memory (a
ModuleDescPtr). Sadly, xf86LoadModules dropped the return value on the floor
leaking memory for each module it loaded.

All the failure paths were very diligent in freeing the "fullpath" temporary
string, but the success case was not. All the content only got strdup()d, so
it's not live memory anymore.

xf86LogInit allocates a piece of memory, stores it in lf. LogInit() will then
effectively strdup it, but lf is never freed again.

We need to start breaking the XKB API to enforce sanity, so drag whichever
headers we need to do so into the server tree, as the client API is set in
stone, being part of Xlib.
Now resizing it won't produce weir overlaps of the widgets. Thanks to
Pelle Johansson for his help showing me how to do this.
(cherry picked from commit ef3498e92d)
After trying to switch from X to VT (or just quit) the video-amd driver
attempts to issue INT 10/0 to go to mode 3 (VGA). The emulator, running
the BIOS code, would then spit out:
c000:0282: A2 ILLEGAL EXTENDED X86 OPCODE!
The opcode was 0F A2, or CPUID; it was not implemented in the emulator.
This simple patch, against 1.3.0.0, handles the CPUID instruction in one of
two ways:
1) if ran on __i386__ or __x86_64__ then it calls the CPUID instruction
directly.
2) if ran elsewhere it returns a canned 486dx4 set of values for
function 1.
This fix allows the video-amd driver to switch back to console mode,
with the GSW BIOS.
Thanks to Symbio Technologies for funding my work, and ThinCan for
providing hardware :)

'Loading foo' is verbosity 3, whereas 'already built-in' is verbosity 0.
This means that gdm's log would just be full of bare 'module already
built-in' messages.
