Prior to this commit the Xorg.wrap code to detect if root rights are
necessary checked for DRM_IOCTL_MODE_GETRESOURCES succeeding *and*
reporting more then 0 output connectors.
DRM_IOCTL_MODE_GETRESOURCES succeeding alone is enough to differentiate
between old drm only cards (which need ums and thus root) and kms capable
cards.
Some hybrid gfx laptops have 0 output connectors on one of their 2 GPUs,
resulting in Xorg needlessly running as root. This commits removes the
res.count_connectors > 0 check, fixing this.

Special case for the systemd-logind case in xfree86: when we're vt-switched
away and a device is plugged in, we get a paused fd from logind. Since we
can't probe the device or do anything with it, we store that device in the
xfree86 and handle it later when we vt-switch back. The device is not added to
inputInfo.devices until that time.
When the device is removed while still vt-switched away, the the config system
never notifies the DDX. It only runs through inputInfo.devices and our device
was never added to that.
When a device is plugged in, removed, and plugged in again while vt-switched
away, we have two entries in the xfree86-specific list that refer to the same
device node, both pending for addition later. On VT switch back, the first one
(the already removed one) will be added successfully, the second one (the
still plugged-in one) fails. Since the fd is correct, the device works until
it is removed again. The removed devices' config_info (i.e. the syspath)
doesn't match the actual device we addded tough (the input number increases
with each plug), it doesn't get removed, the fd remains open and we lose track
of the fd count. Plugging the device in again leads to a dead device.
Fix this by adding a call to notify the DDX to purge any remainders of devices
with the given config_info, that's the only identifiable bit we have at this
point.

The new platform bus code and the old PCI bus code overlap. Platform bus
can handle any type of device, including PCI devices, whereas the PCI code
can only handle PCI devices. Some drivers only support the old style
PCI-probe methods, but the primary device detection code is server based,
not driver based; so we might end up with a primary device which only has
a PCI bus-capable driver, but was detected as primary by the platform
code, or the other way around.
(The above paragraph was shamelessly stolen from Hans de Goede, and
customized.)
The latter case applies to QEMU's virtio-gpu-pci device: it is detected as
a BUS_PCI primary device, but we actually probe it first (with the
modesetting driver) through xf86platformProbeDev(). The
xf86IsPrimaryPlatform() function doesn't recognize the device as primary
(it bails out as soon as it sees BUS_PCI); instead, we add the device as a
secondary graphics card under "autoAddGPU". In turn, the success of this
automatic probing-as-GPU prevents xf86CallDriverProbe() from proceeding to
the PCI probing.
The result is that the server exits with no primary devices detected.
Commit cf66471353 ("xfree86: use udev to provide device enumeration for
kms devices (v10)") added "cross-bus" matching to xf86IsPrimaryPci(). Port
that now to xf86IsPrimaryPlatform(), so that we can probe virtio-gpu-pci
as a primary card in platform bus code.

When using secondary GPU outputs the primary GPU's blockhandler
will copy changes from its framebuffer to a pixmap shared with the
secondary GPU.
In reverse prime setups the secondary GPU's blockhandler will do another
copy from the shared pixmap to its own framebuffer.
Before this commit, if the primary GPU's blockhandler would run after
the secondary GPU's blockhandler and no events were pending, then the
secondary GPU's blockhandler would not run until some events came in
(WaitForSomething() would block in the poll call), resulting in the
secondary GPU output sometimes showing stale contents (e.g. a just closed
window) for easily up to 10 seconds.
This commit fixes this by setting the timeout passed into the
blockhandler to 0 if any shared pixmaps were updated by the primary GPU,
forcing an immediate re-run of all blockhandlers.

Almost all drivers support both the xf86platformBus and xf86pciBus

Since the platformBus paths do not call xf86AddBusDeviceToConfigure()
this results in Xorg -configure failing with the following error:
"No devices to configure. Configuration failed.".
Adding support for the xf86Configure code to xf86platformBus.c

This is a problem for the libinput driver that uses the same context across

(and the only way to do so is to add it to libinput) when the input thread
comes in an reads events. This then causes mayhem when data is dereferenced
that hasn't been set up yet.
In my case the cause was the call to libinput_path_remove_device() inside
preinit racing with evdev_dispatch_device() handling of ENODEV. The sequence
was:
- thread 2 gets an event and calls evdev_dispatch_device()
- thread 1 calls libinput_path_remove_device() which sets the device->source
to NULL
- thread 2 reads from the fd, gets ENODEV and now removes the device->source,
dereferencing the null-pointer

Server GPUs often have a VNC feature attached to allow remote console.
The controller implementing this feature is usually not very powerful,
and we can easily swamp it with work. This is made somewhat worse by
damage over-reporting the size of the dirty region, and a whole lot
worse by applications (or shells) that update the screen with identical
pixel content as was already there.
Fix this by double-buffering the shadow fb, using memcmp to identify
dirty tiles on each update pass. Since both shadows are in host memory
the memcmp is cheap, and worth it given the win in network bandwidth.
The tile size is somewhat arbitrarily chosen to be one cacheline wide at
32bpp on Intel Core.
By default we enable this behaviour for (a subset of) known server GPUs;
the heuristic could use work.

With the previous patch, the modesetting driver can now return whether
the driver supports hw cursor. However, it alone doesn't suffice,
unfortunately. drmmode_load_cursor_argb_check() is called in the
following chain:
xf86CursorSetCursor()
-> xf86SetCursor()
-> xf86DriverLoadCursorARGB()
-> xf86_load_cursor_argb()
-> xf86_crtc_load_cursor_argb()
-> drmmode_load_cursor_argb_check()
*but* at first with drmmode_crtc->cursor_up = FALSE. Then the
function doesn't actually set the cursor but returns TRUE
unconditionally. The actual call of drmmode_set_cursor() is done at
first via the show_cursor callback, and there is no check of sw cursor
fallback any longer at this place. Since it's called only once per
cursor setup, so the xserver still thinks as if the hw cursor is
supported.
This patch is an ad hoc fix to correct the behavior somehow: it does
call drmmode_set_cursor() at the very first time even if cursor_up is
FALSE, then quickly hides again. In that way, whether the hw cursor
is supported is evaluated in the right place at the right time.
Of course, it might be more elegant if we have a more proper mechanism
to fall back to sw cursor at any call path. But it'd need more
rework, so I leave this workaround as is for now.

Reverse PRIME seems to be designed with discrete graphics as a sink in
mind, designed to do an extra copy from sysmem to vidmem to prevent a
discrete chip from needing to scan out from sysmem.
The criteria it used to detect this case is if we are a GPU screen and
Glamor accelerated. It's possible for i915 to fulfill these conditions,
despite the fact that the additional copy doesn't make sense for i915.
Normally, you could just set AccelMethod = none as an option for the device
and call it a day. However, when running with modesetting as both the sink
and the source, Glamor must be enabled.
Ideally, you would be able to set AccelMethod individually for devices
using the same driver, but there seems to be a bug in X option parsing that
makes all devices on a driver inherit the options from the first detected
device. Thus, glamor needs to be enabled for all or for none until that bug
(if it's even a bug) is fixed.
Nonetheless, it probably doesn't make sense to do the extra copy on i915
even if Glamor is enabled for the device, so this is more user friendly by
not requiring users to disable acceleration for i915.

UDL (USB 2.0 DisplayLink DRM driver) and other drivers for USB transport devices
have strange semantics when it comes to vblank events, due to their inability to
get the actual vblank info.
When doing a page flip, UDL instantly raises a vblank event without waiting for
vblank. It also has no support for DRM_IOCTL_WAIT_VBLANK, and has some strange
behavior with how it handles damage when page flipping.
It's possible to get something semi-working by hacking around these issues,
but even then there isn't much value-add vs single buffered PRIME, and it
reduces maintainability and adds additional risks to the modesetting driver
when running with more well-behaved DRM drivers.
Work needs to be done on UDL in order to properly support synchronized
PRIME. For now, just blacklist it, causing RandR to fall back to
unsynchronized PRIME.
This patch originally blacklisted UDL by name, but it was pointed out that there
are other USB transport device drivers with similar limitations, so it was

Implements (Enable/Disable)SharedPixmapFlipping and
SharedPixmapNotifyDamage, the sink functions for PRIME synchronization and
double buffering. Allows modesetting driver to be used as a sink with PRIME
synchronization.
Changes dispatch_slave_dirty to flush damage from both scanout pixmaps.
Changes drmmode_set_scanout_pixmap*() functions to
drmmode_set_target_scanout_pixmap*() that take an additional parameter
PixmapPtr *target. Then, treat *target as it did prime_pixmap. This allows
me to use it to explicitly set both prime_pixmap and prime_pixmap_back
individually. drmmode_set_scanout_pixmap() without the extra parameter
remains to cover the single-buffered case, but only works if we aren't
already double buffered.
driver.c:
Add plumbing for rr(Enable/Disable)SharedPixmapFlipping and
SharedPixmapNotifyDamage.
Change dispatch_dirty_crtc to dispatch_dirty_pixmap, which functions the
same but flushes damage associated with a ppriv instead of the crtc, and
chanage dispatch_slave_dirty to use it on both scanout pixmaps if
applicable.
drmmode_display.h:
Add flip_seq field to msPixmapPrivRec to keep track of the event handler
associated with a given pixmap, if any.
Add wait_for_damage field to msPixmapPrivRec to keep track if we have
requested a damage notification from the source.
Add enable_flipping field to drmmode_crtc_private_rec to keep track if
flipping is enabled or disabled.
Add prime_pixmap_back to drmmode_crtc_private_rec to keep track of back
buffer internally.
Add declarations for drmmode_SetupPageFlipFence(),
drmmode_EnableSharedPixmapFlipping(),
drmmode_DisableSharedPixmapFlipping, drmmode_SharedPixmapFlip(), and
drmmode_SharedPixmapPresentOnVBlank().
Move slave damage from crtc to ppriv.
drmmode_display.c:
Change drmmode_set_scanout_pixmap*() functions to
drmmode_set_target_scanout_pixmap*() that take an additional parameter
PixmapPtr *target for explicitly setting different scanout pixmaps.
Add definitions for functions drmmode_SharedPixmapFlip(),
drmmode_SharedPixmapPresentOnVBlank(),
drmmode_SharedPixmapPresent(),
drmmode_SharedPixmapVBlankEventHandler(),
drmmode_SharedPixmapVBlankEventAbort(),
drmmode_EnableSharedPixmapFlipping(), and
drmmode_DisableSharedPixmapFlipping,
drmmode_InitSharedPixmapFlipping(), and
drmmode_FiniSharedPixmapFlipping, along with struct
vblank_event_args.
The control flow is as follows:
pScrPriv->rrEnableSharedPixmapFlipping() makes its way to
drmmode_EnableSharedPixmapFlipping(), which sets enable_flipping to
TRUE and sets both scanout pixmaps prime_pixmap and
prime_pixmap_back.
When setting a mode, if prime_pixmap is defined, modesetting
driver will call drmmode_InitSharedPixmapFlipping(), which if
flipping is enabled will call drmmode_SharedPixmapPresent() on
scanout_pixmap_back.
drmmode_SharedPixmapPresent() requests that for the source to
present on the given buffer using master->PresentSharedPixmap(). If
it succeeds, it will then attempt to flip to that buffer using
drmmode_SharedPixmapFlip(). Flipping shouldn't fail, but if it
does, it will raise a warning and try drmmode_SharedPixmapPresent()
again on the next vblank using
drmmode_SharedPixmapPresentOnVBlank().
master->PresentSharedPixmap() could fail, in most cases because
there is no outstanding damage on the mscreenpix tracked by the
shared pixmap. In this case, drmmode_SharedPixmapPresent() will
attempt to use master->RequestSharedPixmapNotifyDamage() to request
for the source driver to call slave->SharedPixmapNotifyDamage() in
response to damage on mscreenpix. This will ultimately call
into drmmode_SharedPixmapPresentOnVBlank() to retry
drmmode_SharedPixmapPresent() on the next vblank after
accumulating damage.
drmmode_SharedPixmapFlip() sets up page flip event handler by
packing struct vblank_event_args with the necessary parameters, and
registering drmmode_SharedPixmapVBlankEventHandler() and
drmmode_SharedPixmapVBlankEventAbort() with the modesetting DRM
event handler queue. Then, it uses the drmModePageFlip() to flip on
the next vblank and raise an event.
drmmode_SharedPixmapPresentOnVBlank() operates similarly to
drmmode_SharedPixmapFlip(), but uses drmWaitVBlank() instead of
drmModePageFlip() to raise the event without flipping.
On the next vblank, DRM will raise an event that will ultimately be
handled by drmmode_SharedPixmapVBlankEventHandler(). If we flipped,
it will update prime_pixmap and prime_pixmap_back to reflect that
frontTarget is now being displayed, and use
drmmode_SharedPixmapPresent(backTarget) to start the process again
on the now-hidden shared pixmap. If we didn't flip, it will just
use drmmode_SharedPixmapPresent(frontTarget) to start the process
again on the still-hidden shared pixmap.
Note that presentation generally happens asynchronously, so with
these changes alone tearing is reduced, but we can't always
guarantee that the present will finish before the flip. These
changes are meant to be paired with changes to the sink DRM driver
that makes flips wait on fences attached to dmabuf backed buffers.
The source driver is responsible for attaching the fences and
signaling them when presentation is finished.
Note that because presentation is requested in response to a
vblank, PRIME sources will now conform to the sink's refresh rate.
At teardown, pScrPriv->rrDisableSharedPixmapFlipping() will be
called, making its way to drmmode_FiniSharedPixmapFlipping().
There, the event handlers for prime_pixmap and prime_pixmap_back
are aborted, freeing the left over parameter structure. Then,
prime_pixmap and prime_pixmap back are unset as scanout pixmaps.
Register and tear down slave damage per-scanout pixmap instead of
per-crtc.

A new --with-fallback-input-driver=foo option allows selecting a
fallback driver for the server if the driver configured for the device
is not found. Note that this only applies when the device has a driver
assigned and that module fails to load, devices without a driver are
ignored as usual.
This avoids the situation where a configuration assigns e.g. the
synaptics driver but that driver is not available on the system,
resulting in a dead device. A fallback driver can at least provides some
functionality.
This becomes more important as we move towards making other driver true
leaf nodes that can be installed/uninstalled as requested. Specifically,
wacom and synaptics, a config that assigns either driver should be
viable even when the driver itself is not (yet) installed on the system.
It is up to the distributions to make sure that the fallback driver is
always installed. The fallback driver can be disabled with
--without-fallback-input-driver and is disabled by default on non-Linux
systems because we don't have generic drivers on those platforms.
Default driver on Linux is libinput, evdev is the only other serious
candidate here.

The doc text is wrong at this point, input processing isn't going to
vary based on this, so we shouldn't say it does. The only thing this
_does_ get used for is DRI1 SwapBuffers (on everything but savage), and
if you disable it you're not going to get DRI1 at all, so we really
shouldn't even mention it.
Still, leave the option wired up to the parser so we don't break any
DRI1-driver-using setup relying on it being disabled, and so we don't
complain about unused options elsewhere.

This makes the cursor pointer held by xf86Cursors.c get reset to NULL
whenever the cursor isn't displayed, and means that the reference
count held in xf86Cursor.c is sufficient to cover the reference in
xf86Cursors.c.
As HideCursor may be called in the cursor loading path after
UseHWCursor or UseHWCursorARGB when HARDWARE_CURSOR_UPDATE_UNHIDDEN
isn't set in the Flags field, the setting of the cursor pointer had to
be moved to the LoadCursor paths.
LoadCursorARGBCheck gets the cursor pointer, but LoadCursorImageCheck
does not. For LoadCursorImageCheck, I added a new function,
xf86CurrentCursor, which returns the current cursor. With this new
function, we can eliminate the cursor pointer from the
xf86CrtcConfigRec, once drivers are converted over to use it.

All supported hotplug backends (udev, hal, and wscons) will set both

will set ATTR_KEY, but not ATTR_KEYBOARD, for non-keyboard key input
devices (hal and wscons will set both flags in any case). With this
distinction, kdrive input hotplugging mechanism will be allowed to only

216bdbc735 removed the SetRootClip call in the XWayland output-hotplug
handler when running rootless (e.g. as a part of Weston/Mutter), since
the root window has no storage, so generating exposures will result in
writes to invalid memory.
Unfortunately, preventing the segfault also breaks sprite confinement.
SetRootClip updates winSize and borderSize for the root window, which
when combined with RRScreenSizeChanged calling ScreenRestructured,
generates a new sprite-confinment area to update it to the whole screen.
Removing this call results in the window geometry being reported
correctly, but winSize/borderSize never changing from their values at
startup, i.e. out of sync with the root window geometry / screen
information in the connection info / XRandR.
This patch introduces a hybrid mode, where we update winSize and
borderSize for the root window, enabling sprite confinement to work
correctly, but keep the clip emptied so exposures are never generated.

InputClass sections use various MatchFoo directives to decide which device to
apply to. This usually works fine for specific snippets but has drawbacks for
snippets that apply more generally to a multitude of devices.
This patch adds a NoMatchFoo directive to negate a match, thus allowing
snippets that only apply if a given condition is not set. Specifically, this
allows for more flexible fallback driver matching, it is now possible to use a
snippet that says "assign driver foo, but only if driver bar wasn't already
assigned to it". For example:
Section "InputClass"
Identifier "libinput for tablets"
MatchIsTablet "true"
NoMatchDriver "wacom"
Driver "libinput"
EndSection
The above only assigns libinput to tablet devices if wacom isn't already
assigned to this device, making it possible to select a specific driver by
installing/uninstalling it.

(Sorry for double posting)
I repost this patch because I havn't got any replies from maintainers
since I posted the initial patch back in March.
Some instructions are not emulated correctly by x86emu when they
are prefixed by the 0x66 opcode.
I've identified problems in the emulation of these intructions: ret,
enter, leave, iret and some forms of call.
Most of the time, the problem is that these instructions should push or
pop 32-bit values to/from the stack, instead of 16bit, when they are
prefixed by the 0x66 special opcode.
The SeaBIOS project aims to produce a complete legacy BIOS
implementation as well as a VGA option ROM, entirely written in C and
using the GCC compiler.
In 16bit code produced by the GCC compiler, the 0x66 prefix is used
almost everywhere. This patch is necessary to allow the SeaBIOS VGA
option ROM to function with Xorg when using the vesa driver.
SeaBIOS currently use postprocessing on the ROM assembly output to
replace the affected instruction with alternative unaffected instructions.
This is obviously not very elegant, and this fix in x86emu would be
more appropriate.
v2: - Decrement BP instead of EBP in accordance with the Intel Manual
- Assign EIP instead of IP when poping the return address from the
stack in 32-bit operand size mode in ret_far_IMM, ret_far, and iret
- When poping EFLAGS from the stack in iret in 32-bit operand size
mode, apply some mask to preserve Read-only flags.
v3: - Rebase

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.

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.

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.

This patch makes 0/90/180/270 rotation work with USB output

and any updates to the shared pixmap are done using a composite

v3: Hack around DPMS shenanigans. If all monitors are DPMS off, then

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
