88f22fc5da linux: Do not call FatalError from xf86CloseConsole
FatalError ends up calling xf86CloseConsole itself, so calling FatalError
from within xf86CloseConsole is not a good idea.

Make switch_to log errors using xf86Msg(X_WARNING, ...) and return success
(or failure).

This makes switch_to match the other error checking done in xf86CloseConsole
which all logs warnings and continues.

Add checking of the return value in xf86OpenConsole and call
FatalError there when switch_to fails, to preserve the error-handling
behavior of xf86OpenConsole.

Check for integer overflow before using stuff->count in a multiplication,
to avoid compiler optimizing out due to undefined behaviour, but only

f92c0b9f94 Allow system call restarts upon signal interruption
The X server frequently deals with SIGIO and SIGALRM interruptions.
If process execution is inside certain blocking system calls
when these signals arrive, e.g. with the kernel blocked on
a contended semaphore, the system calls will be interrupted.

Some system calls are automatically restartable (the kernel re-executes
them with the same parameters once the signal handler returns) but
only if the signal handler allows it.

Set SA_RESTART on the signal handlers to enable this convenient
behaviour.

9b9d621f11 systemd-logind: don't second guess D-Bus default timeout
At the moment, the X server uses a non-default timeout for D-Bus
messages to systemd-logind. The only timeouts normally used with
D-Bus are:

1) Infinite
2) Default

Anything else is just as arbitrary as Default, and so rarely makes
sense to use instead of Default.

Put another way, there's little reason to be fault tolerant against
a local root running daemon (logind), that in some configurations, the
X server already depends on for proper functionality.

This commit changes systemd-logind to just use the default timeouts.

905126c66c xfree86: Fix xf86_check_platform_slot's handling of PCI
If a PCI entity is found, xf86_check_platform_slot performs a device ID check
against the xf86_platform_device passed in.  However, it just returns
immediately without checking the rest of the entities first.  This leads to this
situation happening:

1. The nvidia driver creates an entity 0 with bus.type == BUS_PCI
2. The intel driver creates entity 1 for its platform device, opening
   /dev/dri/card0
3. xf86platformProbeDev calls probeSingleDevice on the Intel platform device,
   which calls doPlatformProbe, which calls xf86_check_platform_slot.
4. xf86_check_platform_slot compares the Intel platform device against the
   NVIDIA PCI entity.  Since they don't have the same device ID, it returns
   TRUE.
5. doPlatformProbe calls xf86ClaimPlatformSlot, which creates a duplicate entity
   for the Intel one.

Fix this by only returning FALSE if the PCI ID matches, and continuing the loop
otherwise.  In the scenario above, this allows it to continue on to find the
Intel platform device that matches the second entity.

b4703a5a6e modesetting: Refactor drmmode_glamor_new_screen_pixmap
The original drmmode_glamor_new_screen_pixmap function was specific to the
primary screen pixmap.  This commit pulls the guts out into a new, more
general, drmmode_set_pixmap_bo function for setting a buffer on a pixmap.
The new function also properly tears down the glamor bits if the buffer
being set is NULL.  The drmmode_glamor_new_screen_pixmap function is now
just a 3-line wrapper around drmmode_set_pixmap_bo.

v2 Jason Ekstrand <jason.ekstrand@intel.com>:
 - Re-arranged code in drmmode_set_pixmap_bo and
   drmmode_glamor_handle_new_screen_pixmap so that glamor_set_screen_pixmap
   only gets called for the screen pixmap

4e12d7b6f4 modesetting: Update the cursor without hiding it
In the new KMS APIs, the legacy drmModeSetCursor ioctl actually waits
for a vblank after changing the cursor image before returning, meaning
that the X server, in attempting to hide the cursor before updating
its image, actually makes that hide *visible* for a full vblank.

It's unknown why the X server does this by default, but turn it off.

If we're with a legacy driver that doesn't support the modern
drmModeSetCursor by waiting for a vblank before returning, we're going
to get a tiny bit of tearing on the cursor plane. But between tearing
with a new cursor image and tearing with a blank cursor image, I'd
rather the former.

The only proper solution to this is an atomic ioctl that page flips
all planes, including the cursor plane, at vblank time and at the same
time.

de89c6b8c6 xfree86: rename Xorg.bin to Xorg
If the suid wrapper is enabled, /usr/bin/Xorg is just a shell script that
execs either /usr/libexec/Xorg.bin directly or the Xorg.wrap binary which then
execve's /usr/libexec/Xorg.bin.

Either way, we end up with Xorg.bin, which is problematic for two reasons:
* ps shows the command as Xorg.bin
* _COMM and _EXE in systemd's journal will both show Xorg.bin as well

There's not much we can do about the path, but having the actual command stay
as Xorg means better compatibility to existing scripts. And, the reason for
this path: the command
   journalctl _COMM=Xorg
works universally, regardless of whether the wrapper is used or not.

7b784df51b modesetting: Use GBM for buffer allocations if Glamor supports it.
For performance, Glamor wants to render to tiled buffers, not linear
ones.  Using GBM allows us to pick the 3D driver's preferred tiling
modes.

v2: Declare drmmode->gbm as void * if !GLAMOR_HAS_GBM.
v3: Just use a forward declaration of struct gbm_device.

980535757d modesetting: Create a drmmode_bo wrapper; use it for front_bo.
This code is going to be extended to support GBM BOs soon.  This small
abstraction removes a lot of direct dumb_bo access, so we can add that
support in one place, rather than putting conditionals at every
pitch/handle/etc access.

c6388964b0 modesetting: Drop dumb_bo::map_count field and dead unmap code.
The drm kernel API for dumb BOs apparently doesn't include an unmap
ioctl, so we can't do much here.  It looks like this code was copied
from libkms, which was also unfinished.

We may as well delete the dead variable that simply gets incremented
and never read.

87cc0c0d31 modesetting: Move dumb_bo into its own source files.
Eventually, drmmode_display will be able to use GBM for handling
buffers, and won't need dumb_bo.  Keeping the display related logic
and buffer object abstraction in separate files seems a bit tidier.

There is an integer overflow in the validation. This can cause
