Egbert Eich 3cd7d33380 randr: Remove senseless checks for xf86RandR12Key
When xf86RandR12Key is not set we will not get to the places where
these tests are done as the functions in question are not called.
In most cases we would have crashed before these checks anyway.

Daniel Drake 94ab7455ab 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.

Ilia Mirkin 139e36dd5c modesetting: fix up output naming convention
A user on a nouveau-driven card ran into a problem where DVI-D-1 and
DVI-I-1 were aliasing. The simplest fix is to provide the full connector
names. While we're at it, rename the output names to match what is in
the kernel, and start counting the connectors from 1 rather than 0. The
only deviation is HDMI vs HDMI-A, which kept its original name.

This will break backwards compatibility with existing xorg.conf's that
reference output names, but the alternative is to create a separate
counting system, further disconnecting from the kernel names.

Olivier Fourdan d206c240c0 configurable maximum number of clients
Make the maximum number of clients user configurable, either from the command
line or from xorg.conf

This patch works by using the MAXCLIENTS (raised to 512) as the maximum
allowed number of clients, but allowing the actual limit to be set by the
user to a lower value (keeping the default of 256).

There is a limit size of 29 bits to be used to store both the client ID and
the X resources ID, so by reducing the number of clients allowed to connect to
the X server, the user can increase the number of X resources per client or
vice-versa.

Parts of this patch are based on a similar patch from Adam Jackson

Dave Airlie 90db5edf11 prime: add rotation support for offloaded outputs (v2)
One of the lacking features with output offloading was
that screen rotation didn't work at all.

This patch makes 0/90/180/270 rotation work with USB output
and GPU outputs.

When it allocates the shared pixmap it allocates it rotated,
and any updates to the shared pixmap are done using a composite
path that does the rotation. The slave GPU then doesn't need
to know about the rotation and just displays the pixmap.

v2:
rewrite the sync dirty helper to use the dst pixmap, and
avoid any strange hobbits and rotations.

This breaks ABI in two places.

Kenneth Graunke 13c7d53df8 modesetting: Implement page flipping support for Present.
Based on code by Keith Packard, Eric Anholt, and Jason Ekstrand.

v2:
- Fix double free and flip_count underrun (caught by Mario Kleiner).
- Don't leak flip_vblank_event on the error_out path (Mario).
- Use the updated ms_flush_drm_events API (Mario, Ken).

v3: Hack around DPMS shenanigans.  If all monitors are DPMS off, then
    there is no active framebuffer; attempting to pageflip will hit the
    error_undo paths, causing us to drmModeRmFB with no framebuffer,
    which confuses the kernel into doing full modesets and generally
    breaks things.  To avoid this, make ms_present_check_flip check that
    some CRTCs are enabled and DPMS on.  This is an ugly hack that would
    get better with atomic modesetting, or some core Present work.

v4:
- Don't do pageflipping if CRTCs are rotated (caught by Jason Ekstrand).
- Make pageflipping optional (Option "PageFlip" in xorg.conf.d), but
  enabled by default.

v5: Initialize num_crtcs_on to 0 (caught by Michel Dänzer).

v6: merge async flip support from Mario Kleiner

Kenneth Graunke f6853baeba modesetting: Improve the ms_flush_drm_events() API.
Previously, ms_flush_drm_events() returned a boolean value, and it was
very easy to interpret the meaning incorrectly.  Now, we return an
integer value.

The possible outcomes of this call are:
- poll() raised an error (formerly TRUE, now -1 - poll's return value)
- poll() said there are no events (formerly TRUE, now 0).
- drmHandleEvent() raised an error (formerly FALSE, now the negative
  value returned by drmHandleEvent).
- An event was successfully handled (formerly TRUE, now 1).

The nice part is that this allows you to distinguish errors (< 0),
nothing to do (= 0), and success (1).  We no longer conflate errors
with success.

v2: Change ms_present_queue_vblank to < 0 instead of <= 0, fixing an
    unintentional behavior change.  libdrm may return EBUSY if it's
    received EINTR for more than a second straight; just keep retrying
    in that case.  Suggested by Jasper St. Pierre.

David Herrmann 780a69aff0 systemd-logind: do not rely on directed signals
Right now, Xorg does not install DBus matches for "PauseDevice" /
"ResumeDevice". Therefore, it should usually not receive those DBus
signals from logind. It is just a coincidence that systemd-logind sends
those signals in a directed manner right now. Therefore, dbus-daemon
bypasses the broadcast matches.

However, this is not ABI and Xorg should not rely on this. systemd-logind
is free to send those signals as broadcasts, in which case Xorg will
freeze the VT. Fix this by always installing those matches.

The fix for this is easy, we must not use systemd-logind integration when

But the final KeepTty value is not known until the code to chose which vtno to
run on has been called, which currently happens after intializing
systemd-logind.

This commit is step 1 in fixing the "startx -- vt7" breakage, it factors out
the linux xf86OpenConsole bits which set xf86Info.vtno and keepTty so that
these can be called earlier. Calling this earlier is safe as this code has
no side effects other than setting xf86Info.vtno and keepTty.

Note this basically only moves a large chunk of xf86OpenConsole() into
linux_parse_vt_settings() without changing a single line of it, this is
hard to see in the diff because the identation level has changed.

Peter Hutterer 4c2f2cb4c8 dix: Add unaccelerated valuators to the ValuatorMask
Allows a mask to carry both accelerated and unaccelerated motion at the same
time.

This is required for xf86-input-libinput where the pointer acceleration
happens in libinput already, but parts of the server, specifically raw events
and DGA rely on device-specific unaccelerated data.

To ease integration add this as a second set to the ValuatorMask rather than
extending all APIs to carry a second, possibly NULL set of valuators.

Note that a valuator mask should only be used in either accel/unaccel or
standard mode at any time. Switching requires either a valuator_mask_zero()
call or unsetting all valuators one-by-one. Trying to mix the two will produce
a warning.

The server has a shortcut for changing a mask with the
valuator_mask_drop_unaccelerated() call. This saves us from having to loop
through all valuators on every event, we can just drop the bits we know we
don't want.

So only return when the drmModeSetCursor2 succeeds (i.e returns 0) and disable
the cursor2 usage on EINVAL.

Jason Gerecke 28159eff6b xfree86: Return NULL from xf86CompatOutput if no compat_output is defined
If no compat_output is defined, we inadvertently (attempt to) return
whatever data is at index -1. Instead, return NULL since that's what
callers are expecting.

Dave Airlie 9257b1252d modesetting: add dynamic connector hotplug support (MST) (v3)
This is ported from the same code in the ati and intel drivers,

It uses the same option name as nvidia and the other DDXes to
disable tearing down outputs as it is hard to avoid racing with clients.

v2: address two issues with DeleteUnusedDP12 enabled, reported
by Daniel Martin,
a) check we have a mode_output before destroying it
b) only delete *unused* displays (thanks Aaron for clarifying)
so we check if the output has a crtc and if it does we don't
delete it.

v3: drop the option to delete unused displays, just encode
behaviour into the randr spec.
