DRM_EVENT_CONTEXT_VERSION is the latest context version supported by
whatever version of libdrm is present. modesetting was blindly asserting
it supported whatever version that may be, even if it actually didn't.
With libdrm 2.4.78, setting a higher context version than 2 will attempt
to call the page_flip_handler2 vfunc if it was non-NULL, which being a
random chunk of stack memory, it might well have been.
Set the version as 2, which should be bumped only with the appropriate
version checks.

Currently if modesetting ever fails to set a hardware cursor it will switch
to using a software cursor and never go back. Change this to only
permanently switch to a software cursor if -ENXIO is returned (which means
hardware cursors not supported), and to otherwise still try a hardware
cursor first every time a new one is set. This is needed because hardware
may be able to handle some cursors in hardware and others not, or virtual
hardware may be able to handle hardware cursors at some times and not
others.
Changes since v1, v2 and v3:
* take into account the switch to load_cursor_argb_check
* keep the permanent software cursor fall-back if -ENXIO is returned
* move parts of v3 into separate patches

Based on v4 by Alexandre Courbot <acourbot@nvidia.com>
There is currently no reliable way to report failure to set a HW
cursor. Still such failures can happen if e.g. the MODE_CURSOR DRM
ioctl fails (which currently happens at least with modesetting on Tegra
for format incompatibility reasons).
As failures are currently handled by setting the HW cursor size to
(0,0), the fallback to SW cursor will not happen until the next time the
cursor changes and xf86CursorSetCursor() is called again. In the
meantime, the cursor will be invisible to the user.
This patch addresses that by adding _xf86CrtcFuncs::set_cursor_check and
_xf86CursorInfoRec::ShowCursorCheck hook variants that return booleans.
This allows to propagate errors up to xf86CursorSetCursor(), which can
then fall back to using the SW cursor immediately.
v5:
- Removed parts of patch already committed as part of 14c21ea1.
- Adjusted code slightly to match surrounding code.
- Effectively reverted af916477 which is made unnecessary by this patch.

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.

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.

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

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.

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.

By keeping track of the scanout pixmap in its internal state, modesetting

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.

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.

This is derived from the intel driver DRI2 code, with swapchain and
pageflipping dropped, functions renamed, and vblank event management
shared code moved to a vblank.c for reuse by Present.
This allows AIGLX to load, which means that you get appropriate
visuals exposed in GL, along with many extensions under
direct-rendering that require presence in GLX (which aren't supported
in glxdriswrast.c).
v2: Drop unused header includes in pageflip.c, wrap in #ifdef GLAMOR.
Drop triple-buffering, which was totally broken in practice (I'll
try to fix this later). Fix up some style nits. Document the
general flow of pageflipping and why, rename the DRI2 frame event
type enums to reflect what they're for, and handle them in a
single switch statement so you can understand the state machine
more easily.
v3: Drop pageflipping entirely -- it's unstable on my Intel laptop
(not that the normal 2D driver is stable with pageflipping for
me), and I won't get it fixed before the merge window. It now
passes all of the OML_sync_control tests from Jamey and Theo
(except for occasional warns in timing -fullscreen -divisor 2).
v4: Fix doxygen at the top of vblank.c

If a device is not primary, the PCI device match fails because the
xf86-video-modesetting driver looks specifically for a PCI class match of
0x30000 with a mask of 0xffffff. This fails to match, for example, a
non-primary Intel VGA device, because it is reported as having a class of
0x38000.
Fix that by ignoring the low 16 bits of the class in the pci_id_match table.

A fixed-mode output device like a panel will often only inform of its
preferred mode through its EDID. However, the driver will adjust user
specified modes for display through use of a panel-fitter allowing
greater flexibility in upscaling. This is often used by games to set a
low resolution for performance and use the panel fitter to fill the
screen.
v2: Use the presence of the 'scaling mode' connector property as an
indication that a panel fitter is attached to that pipe.
