Hans De Goede bc3eed379e modesetting: Hide cursor when initializing crtc
When Xorg gets started directly from a wayland-gdm the crtc still has the
wayland hw cursor set. Combine this with Xorg immediately falling back to
a sw cursor because a slave-output has a monitor attached at startup; and
we end up with the wayland hardware cursor overlay fixed in its last
position + the Xorg sw cursor resulting in 2 cursors.

This commit fixes this by hiding any left-over cursors when initializing
the crtc.

Hans De Goede 6c984ac9a7 modesetting: Do not use function local static variables
The modesetting driver may be driving 2 screens (slave and master
gpu), which may have different behavior wrt hardware cursor support.

So stop using static variables and instead store the hw-cursor support
related data in a per screen struct. While at it actually make it per
crtc data as in theory different crtc's could have different hw-cursor
support.

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.

Dave Airlie 21217d0216 modesetting: Implement 32->24 bpp conversion in shadow update
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

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.

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.

glamor_name_from_pixmap and glamor_fd_from_pixmap return CARD16 and
CARD32 values via pointers.  The current code uses uint16_t and
uint32_t which will probably be the same but it's safer to use the
datatypes as specified by the function.

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).

[airlied: took over]
v6: merge async flip support from Mario Kleiner
free sequence after failed vblank queue
handle unflip while DPMS'ed off (Michel)
move flip tracking into its own structure, and
fix up reference counting issues, and add comments.

Dave Airlie 7328fb3f2b modesetting: reverse prime support (v1.1)
This adds support for reverse prime to the modesetting driver.

Reverse prime is where we have two GPUs in the display chain,
but the second GPU can't scanout from the shared pixmap, so needs
an extra copy to the on screen pixmap.

This allows modesetting to support this scenario while still
supporting the USB offload one.

v1.1:
fix comment + ret = bits (Eric)

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.

Jason Ekstrand b4703a5a6e modesetting: Refactor drmmode_glamor_new_screen_pixmap
The original drmmode_glamor_new_screen_pixmap function was specific to the
primary screen pixmap.  This commit pulls the guts out into a new, more
general, drmmode_set_pixmap_bo function for setting a buffer on a pixmap.
The new function also properly tears down the glamor bits if the buffer
being set is NULL.  The drmmode_glamor_new_screen_pixmap function is now
just a 3-line wrapper around drmmode_set_pixmap_bo.

v2 Jason Ekstrand <jason.ekstrand@intel.com>:
 - Re-arranged code in drmmode_set_pixmap_bo and
   drmmode_glamor_handle_new_screen_pixmap so that glamor_set_screen_pixmap
   only gets called for the screen pixmap
 - Guard the call to glamor_set_screen_pixmapa with a drmmode->glamor check
