Darren Etheridge 39de619413 drm/tilcdc fixing i2c/slave initialization race
In certain senarios drm will initialize before i2c this means that i2c
slave devices like the nxp tda998x will fail to be probed.  This patch
detects this condition then defers the probe of the slave device and
the tilcdc main driver.

The tilcdc has a number of limitations for the allowed sizes of
the various adjustable timing parameter.  Some modes are outside
of these timings.  This commit will prune modes that report timings
that will overflow the allowed sizes in the tilcdc.

Daniel Vetter 160954b7bc drm: kms_helper: don't lose hotplug event
There's a race window (small for hpd, 10s large for polled outputs)
where userspace could sneak in with an unrelated connnector probe
ioctl call and eat the hotplug event (since neither the hpd nor the
poll code see a state change).

To avoid this, check whether the connector state changes in all other
->detect calls (in the current helper code that's only probe_single)
and if that's the case, fire off a hotplug event. Note that we can't
directly call the hotplug event handler, since that expects that no
locks are held (due to reentrancy with the fb code to update the kms
console).

Also, this requires that drivers using the probe_single helper
function set up the poll work. All current drivers do that already,
and with the reworked hpd handling there'll be no downside to
unconditionally setting up the poll work any more.

Daniel Vetter 5cef29aa52 drm: fix fb leak in setcrtc
Drivers are allowed (actually have to) disable unrelated crtcs in
their ->set_config callback (when we steal all the connectors from
that crtc). If they do that they'll clear crtc->fb to NULL.

Which results in a refcount leak, since the drm core is keeping track
of that reference.

To fix this track the old fb of all crtcs and adjust references for
all of them. Of course, since we only hold an additional reference for
the fb for the current crtc we need to increase refcounts before we
drop the old one.

This approach has the benefit that it inches us a bit closer to an
atomic modeset world, where we want to update the config of all crtcs
in one step.

This regression has been introduce in the framebuffer refcount
conversion, specifically in

Daniel Vetter cc85e1217f drm: check that ->set_config properly updates the fb
Historically drm lacked fb refcounting, so the updating of crtc->fb
was done by the lower levels at a point convenient to get their own
refcounting (e.g. refcounts for the underlying gem bo, pinning
refcounts) right. With the introduction of refcounted fbs the drm core
handled the fb refcounts, but still relied on drivers to update the
crtc->fb pointer (this approach required the least invasive changes in
drivers).

Enforce this contract with a WARN_ON.

Daniel Vetter 372835a852 drm/crtc-helper: explicit DPMS on after modeset
Atm the crtc helper implementation of set_config has really
inconsisten semantics: If just an fb update is good enough, dpms state
will be left as-is, but if we do a full modeset we force everything to
dpms on.

This change has already been applied to the i915 modeset code in

    drm/i915: force full modeset if the connector is in DPMS OFF mode

The history of this dpms forcing is pretty interesting. This patch
here is an almost-revert of

of funny stuff in it.

Christopher Harvey a080db9fdd drm/mgag200: Hardware cursor support
G200 cards support, at best, 16 colour palleted images for the cursor
so we do a conversion in the cursor_set function, and reject cursors
with more than 16 colours, or cursors with partial transparency. Xorg
falls back gracefully to software cursors in this case.

We can't disable/enable the cursor hardware without causing momentary
corruption around the cursor. Instead, once the cursor is on we leave
it on, and simulate turning the cursor off by moving it
offscreen. This works well.

Since we can't disable -> update -> enable the cursors, we double
buffer cursor icons, then just move the base address that points to
the old cursor, to the new. This also works well, but uses an extra
page of memory.

The cursor buffers are lazily-allocated on first cursor_set. This is
to make sure they don't take priority over any framebuffers in case of
limited memory.

Here is a representation of how the bitmap for the cursor is mapped in G200 memory :

  Each line of color cursor use 6 Slices of 8 bytes. Slices 0 to 3
  are used for the 4bpp bitmap, slice 4 for XOR mask and slice 5 for
  AND mask. Each line has the following format:

      //      Byte 0  Byte 1  Byte 2  Byte 3  Byte 4  Byte 5  Byte 6 Byte 7
      //
      // S0:  P00-01  P02-03  P04-05  P06-07  P08-09  P10-11  P12-13 P14-15
      // S1:  P16-17  P18-19  P20-21  P22-23  P24-25  P26-27  P28-29 P30-31
      // S2:  P32-33  P34-35  P36-37  P38-39  P40-41  P42-43  P44-45 P46-47
      // S3:  P48-49  P50-51  P52-53  P54-55  P56-57  P58-59  P60-61 P62-63
      // S4:  X63-56  X55-48  X47-40  X39-32  X31-24  X23-16  X15-08 X07-00
      // S5:  A63-56  A55-48  A47-40  A39-32  A31-24  A23-16  A15-08 A07-00
      //
      //       S0 to S5      = Slices 0 to 5
      //       P00 to P63    = Bitmap - pixels 0 to 63
      //       X00 to X63    = always 0 - pixels 0 to 63

Ville Syrjälä b72447cdf1 drm/i915: Drop bogus fbdev sprite disable code
plane->enabled is never set, so this code didn't do anything.

Also drm_fb_helper_restore_fbdev_mode() will now disable all cursors
and sprites for us, so we don't have to bother anymore.

Ville Syrjälä 3858bc5d53 drm/fb-helper: Disable cursors and planes when restoring fbdev mode
Cursors and plane can obscure whatever fbdev wants to show the user.
Disable them all in drm_fb_helper_restore_fbdev_mode.

After the cursors and planes have been disabled, user space needs to
explicitly re-enable them to make them visible again.

Ville Syrjälä 9125e61868 drm: Add drm_plane_force_disable()
drm_plane_force_disable() will forcibly disable the plane even if user
had previously requested the plane to be enabled.

This can be used to force planes to be off when restoring the fbdev
mode.

The code was simply pulled from drm_framebuffer_remove(), which now
calls the new function as well.

v2: Check plane->fb in drm_plane_force_disable(), drop bogus comment

Jerome Glisse 089920f21d drm/radeon: fix write back suspend regression with uvd v2
UVD ring can't use scratch thus it does need writeback buffer to keep
a valid address or radeon_ring_backup will trigger a kernel fault.

It's ok to not unpin the write back buffer on suspend as it leave in
gtt and thus does not need eviction.

v2: Fix the uvd case.

Jerome Glisse 3813f5ca9a drm/radeon: do not try to uselessly update virtual memory pagetable
If a buffer is never bound to a virtual memory pagetable than don't try
to unbind it. Only drawback is that we don't update the pagetable when
unbinding the ib pool buffer which is fine because it only happens at
suspend or module unload/shutdown.

Fixes spurious messages about buffers without VM mappings. E.g.:
radeon 0000:01:00.0: bo ffff88020afac400 don't has a mapping in vm ffff88021ca2b900

Ville Syrjälä e6e792092e drm/edid: Add both 60Hz and 59.94Hz CEA modes to connector's mode list
Having both modes can be beneficial for video playback cases. If you can
match the video framerate exactly, and the audio and video clocks come
from the same source, you should be able to avoid dropped/repeated
frames without expensive operations such as resampling the audio to
match video output rate.

Rather than add both variants based on the CEA extension short video
descriptors in do_cea_modes(), add only one variant there. Once all
the EDID has been fully probed, do a loop over the entire probed mode
list, during which we add the other variants for all modes that match
CEA modes. This allows us to match modes that didn't come via the CEA
short video descriptors. For example one Samsung TV here doesn't have
the 640x480-60 mode as a SVD, but instead it's specified via a detailed
timing descriptor.
