24bpp front buffers tend to be the least well tested path for client
rendering. On the qemu cirrus emulation, and on some Matrox G200 server
chips, the hardware can't do 32bpp at all. It's better to just allocate
a 32bpp shadow and downconvert in the upload hook than expose a funky
pixmap format to clients.

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
expanded to blacklist all USB transport devices.

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.

Instead, when setting a scanout pixmap, always do teardown of the existing

to set up, stop there.
This maintains the previous behavior in all cases except those with

modesetting relied on randr_crtc->scanout_pixmap being consistent with

Without this patch, drmmode_set_scanout_pixmap_(cpu/gpu) will think that

When the pointer moves from an X11 window to a Wayland native window,
no LeaveNotify event is emitted which can lead to various unexpected
behaviors like tooltips remaining visible after the pointer has left the
window.
Yet the pointer_handle_leave() is called and so is the DIX CheckMotion()
but since the pointer enters a Wayland native window with no other
Xwayland window matching, DoEnterLeaveEvents() does not get invoked and
therefore no LeaveNotify event is sent to the X11 client at the time the
pointer leaves the window for a Wayland native surface.
Restore the XYToWindow() handler in xwayland-input that was previously
removed with commit c1565f3 and use that handler to pretend that the
pointer entered the root window in this case so that the LeaveNotify
event is emitted.

The previous change removed the special case that matched resources of

don't map 1:1 to references on the backing pixmap; a window redirected
by multiple clients (say, by the server since it's on the synthetic
visual, and then manually by a compositor) would have a window pixmap
refcount of 1, but would have those bytes accounted twice.
The right thing is to have Composite wrap window accounting, and add the
pixmap bytes once and only once for the redirection reference.
Note that the view from the client can still be non-intuitive in the
face of Composite. xcompmgr, for example, holds _two_ references to
each window pixmap (one each from CompositeNameWindowPixmap and
RenderCreatePicture), so a synthetic-visual window will have its bytes
split 2/3 to xcompmgr and 1/3 to the server-client. Nothing to be done
about that, and at least this way we're not over-accounting.

I suspect this code predates the common resource hooks for computing
sizes. It's ugly in any case since the Resource extension shouldn't
need to know which extensions can take a reference on pixmaps. Instead,
let's just walk every resource for the client and sum up all the pixmap
bytes that way.
This might be slightly slower since we're calling the size func once for
every resource. On the other hand, it might be slightly faster since we
only walk the resource table once instead of 3-5 times. Probably a
wash, and not really a performance path in any case.

The driver can now specify exactly which aspects of the transform it
wants to handle via XF86DriverTransform* flags.
Since the driver can now choose whether it wants to receive transformed
or untransformed cursor coordinates, xf86CrtcTransformCursorPos no
longer needs to be available to drivers, so make it static.

Even if the driver is handling the transform, we still need to transform
the cursor position for clipping, otherwise we may hide the HW cursor
when the cursor is actually inside the area covered by the CRTC.

Delay expose or configure processing until the event queue is empty so
that we don't end up processing a long series of events one at a
time. Expose events already have a check waiting for the last in a
series, this further improves that by discarding multiple
series of events.

If we end up reading all pending X events in the course of other server
execution, then our notify FD callback won't get invoked and we won't
process them. Fix this by noting that there are queued events in the
block handler, setting the poll timeout to zero and queuing a work
proc to clear the event queue.
v2: use a work proc to clear the event queue rather than doing it in
the block handler directly.

Under glamor, we need to re-create the screen pixmap at the new size
so that we can ask glamor for the associated texture. Fortunately, we
can simply use ephyr_glamor_create_screen_resources to create the new
pixmap.
Because this is being done after the server has started, we need to
walk the window heirarchy and reset any windows pointing at the old
pixmap. I could easily be convinced that this TraverseTree should be
moved to miSetScreenPixmap.

The screen block and wakeup handlers are the only ones which provide a
well known ordering between the wrapping layers; placing these as
close as possible to the server blocking provides a way for the driver
to control the flow of execution correctly.
Switch the shadow code to run in the screen block handler so that it
now occurrs just before the server goes to sleep.
Switch glamor to call down to the driver after it has executed its own
block handler piece, in case the driver needs to perform additional
flushing work after glamor has called glFlush.
These changes ensure that the following modules update the screen in
the correct order:
animated cursors (uses RegisterBlockAndWakeupHandlers dynamically)
composite (dynamic wrapping)
misprite (dynamic wrapping)
shadow (static wrapping)
glamor (static wrapping)
driver (static wrapping)
It looks like there's still a bit of confusion between composite and
misprite; if composite updates after misprite, then it's possible
you'd exit the block handler chain with the cursor left hidden. To fix
that, misprite should be wrapping during ScreenInit time and not
unwrapping. And composite might as well join in that fun, just to make
things consistent.

[v3] ephyr: Use screen block handler for flushing changes
ephyr needs to make sure it calls glXSwapBuffers after glamor finishes
its rendering. As the screen block handler is now called last, we have
to use that instead of a registered block/wakeup handler to make sure
the GL rendering is done before we copy it to the front buffer.

When multiple processes are using GL with indirect rendering a race
condition can make drawables refcount never drop to zero.
This situation could happen when there are many X clients using indirect
GLX:
1 - client1: calls glXMakeCurrent
2 - client2: calls glXMakeCurrent
This is the first context switch for this client. So old_context_tag=0
3 - client1: calls glXRender
For the client, its context is already current.
For the server side lastGLContext points to client2's context.
