Daniel Martin 6804875662 modesetting: Reset output_id if drmModeGetConnector failed
If drmModeGetConnector() fails in drmmode_output_detect(), we have to
reset the output_id to -1 too.

Yet another spot leading to a potential NULL dereference when handling
the mode_output member as output_id was != -1. Though, this case should
be very hard to hit.

Martin Peres bcee1b76aa modesetting: re-set the crtc's mode when link-status goes BAD
Despite all the careful planning of the kernel, a link may become
insufficient to handle the currently-set mode. At this point, the
kernel should mark this particular configuration as being broken
and potentially prune the mode before setting the offending connector's
link-status to BAD and send the userspace a hotplug event. This may
happen right after a modeset or later on.

Upon receiving a hot-plug event, we iterate through the connectors to
re-apply the currently-set mode on all the connectors that have a
link-status property set to BAD. The kernel may be able to get the
link to work by dropping to using a lower link bpp (with the same
display bpp). However, the modeset may fail if the kernel has pruned
the mode, so to make users aware of this problem a warning is outputed
in the logs to warn about having a potentially-black display.

This patch does not modify the current behaviour of always propagating
the events to the randr clients. This allows desktop environments to
re-probe the connectors and select a new resolution based on the new
(currated) mode list if a mode disapeared. This behaviour is expected in
order to pass the Display Port compliance tests.

Michael Thayer eb04b20160 modesetting: allow switching from software to hardware cursors (v5).
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

Michael Thayer ecd0a62323 modesetting: Immediately handle failure to set HW cursor, v5
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.

Adam Jackson fcbafdfd79 modesetting: Implement a double-buffered shadow mode
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.

Takashi Iwai af916477c6 modesetting: Fix hw cursor check at the first call
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.

Alex Goins 80e64dae8a modesetting: Implement PRIME syncing as a sink
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.

Alex Goins b773a9c812 modesetting: Always tear down scanout pixmap
drmmode_set_scanout_pixmap_(cpu/gpu) would only do teardown if ppix ==
NULL. This meant that if there were consecutive calls to
SetScanoutPixmap(ppix != NULL) without calls to SetScanoutPixmap(ppix ==
NULL) in between, earlier calls would be leaked.  RRReplaceScanoutPixmap()
does this today.

Instead, when setting a scanout pixmap, always do teardown of the existing
scanout pixmap before setting up the new one. Then, if there is no new one
to set up, stop there.

This maintains the previous behavior in all cases except those with
multiple consecutive calls to SetScanoutPixmap(ppix != NULL).

Alex Goins f4c37eeee7 modesetting: Internal storage of scanout pixmaps
modesetting relied on randr_crtc->scanout_pixmap being consistent with
calls to SetScanoutPixmap, which is very fragile and makes a lot of
assumptions about the caller's behavior.

For example, RRReplaceScanoutPixmap(), when dropping off with !size_fits,
will set randr_crtc->scanout_pixmap = NULL and then call SetScanoutPixmap.
Without this patch, drmmode_set_scanout_pixmap_(cpu/gpu) will think that
there is no scanout pixmap to tear down, because it's already been set to
NULL.

By keeping track of the scanout pixmap in its internal state, modesetting
can avoid these types of bugs and reduce constraints on calling
conventions.

only deviation is HDMI vs HDMI-A, which kept its original name.

that screen rotation didn't work at all.

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

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.

- 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

    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

Eric Anholt cac4b064f9 modesetting: Add support for DRI2 with glamor.
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

Chris Wilson 75815dbb37 Add missing GTF modes
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.
