John Keeping c240906d36 drm/atomic-helper: Export framebuffer_changed()
The Rockchip driver cannot use drm_atomic_helper_wait_for_vblanks()
because it has hardware counters for neither vblanks nor scanlines.

In order to simplify re-implementing the functionality for this driver,
export the framebuffer_changed() helper so it can be reused.

Dave Airlie 28f03607bb Merge tag 'topic/drm-misc-2016-01-17' of git://anongit.freedesktop.org/drm-intel into drm-next
Since your main drm-next pull isn't out of the door yet I figured I might
as well flush out drm-misc instead of delaying for 4.6. It's really just
random stuff all over, biggest thing probably connector_mask tracking from
Maarten.

Daniel Vetter df7d678bea drm/docs: more leftovers from the big vtable documentation pile
Another pile of vfuncs from the old gpu.tmpl xml documentation that
I've forgotten to delete. I spotted a few more things to
clarify/extend in the new kerneldoc while going through this once
more.

v2: Spelling fixes (Thierry).

v3: More spelling fixes and use Thierry's proposal to clarify why
drivers need to validate modes both in ->mode_fixup and ->mode_valid.

Daniel Vetter 4cba68507c drm/atomic-helper: Reject legacy flips on a disabled pipe
We want this for consistency with existing page_flip semantics.

Since this spurred quite a discussion on IRC also document why we
reject event generation when the pipe is off: It's not that it's hard
to implement, but userspace has a track recording which proves that it's
way too easy to accidentally abuse and cause havoc. We want to make
sure userspace doesn't get away with that.

v2: Somehow thought we do reject events already, but that code only
existed in my imagination ... Also suggestions from Thierry.

Nicolas Iooss 399368aab3 drm: make drm_dev_set_unique() not use a format string
drm_dev_set_unique() uses a format string to define the unique name of a
device.  This feature is not used as currently all the calls to this
function either use "%s" as a format string or directly use
dev_name().

Even though this second kind of call does not introduce security
problems, because there cannot be "%" characters in dev_name() results,
gcc issues a warning when building with -Wformat-security flag
("warning: format string is not a string literal (potentially
insecure)").  This warning is useful to find real bugs like the one
fixed by commit 3958b79266 ("configfs: fix kernel infoleak through
user-controlled format string").  False positives which do not bring
an extra value make the work of finding real bugs harder.

Therefore remove the format-string feature from drm_dev_set_unique().

Daniel Vetter 618100f8a8 Add get_eld audio component for i915/HD-audio
Here are the patchset to add get_eld op to audio component for
 communicating more directly between i915 and HD-audio.
 
 Currently, the HDMI/DP audio status and ELD are notified and obtained
 via the hardware-level communication over HD-audio unsolicited event
 and verbs although the graphics driver holds the exactly same
 information.  As we already have a notification via audio component,
 this is another step forward; namely, the audio driver may fetch
 directly the audio status and ELD via the new component op.
 
 The commits are based on Dave's latest drm-next branch.

Add get_eld audio component for i915/HD-audio

Currently, the HDMI/DP audio status and ELD are notified and obtained
via the hardware-level communication over HD-audio unsolicited event
and verbs although the graphics driver holds the exactly same
information.  As we already have a notification via audio component,
this is another step forward; namely, the audio driver may fetch
directly the audio status and ELD via the new component op.

Ville Syrjälä 6af3e65612 drm: Drop drm_helper_probe_single_connector_modes_nomerge()
Now that the mode type bit merge logic is fixed to only merge
between new probed modes, hopefully we can eliminat the special
case for qxl and virtio. That is make the merge the mode type
bits from all matching new probed modes, just like every other
driver.

qxl and virtio got excluded from the merging in
commit 3fbd6439e4 ("drm: copy mode type in drm_mode_connector_list_update()")
commit abce1ec9b0 ("Revert "drm: copy mode type in drm_mode_connector_list_update()"")

Takashi Iwai cae666ceb8 drm/i915: Add get_eld audio component
Implement a new i915_audio_component_ops, get_eld().  It's called by
the audio driver to fetch the current audio status and ELD of the
given HDMI/DP port.  It returns the size of expected ELD bytes if it's
valid, zero if no valid ELD is found, or a negative error code.  The
current state of audio on/off is stored in the given pointer, too.

Note that the returned size isn't limited to the given max bytes.  If
the size is greater than the max bytes, it means that only a part of
ELD has been copied back.

For achieving this implementation, a new field audio_connector is
added to struct intel_digital_port.  It points to the connector
assigned to the given digital port.  It's set/reset at each audio
enable/disable call in intel_audio.c, and protected with av_mutex.

Since it's a legacy entry point with only two implementation (one each
in atomic and legacy crtc helpers) I've made the documentation for
set_config fairly sparse - no one should ever need to look at this
again, all the ABI we have is baked into code.

For ->page_flip otoh I kept all the extensive docs from the docbook
and even extended it where it was lacking: Currently we have a pile of
legacy page_flip implemantations, and even for atomic drivers there's
not yet a standard implementation in the helpers. Which means every
driver needs to implement this itself, and precise specs are really
valuable.

Otherwise there's just cursor, which really just boils down to "use at

Originally the idea behind void* was to allow different sets of
helpers. But now we have that (with probe, plane, crtc and atomic
helpers) and we still just use the same set of vtables. That's the
only way to make the individual helpers modular and allow drivers to
pick&choose and transition between them. So this flexibility isn't
really needed. Also we have lots of non-vtable data meanwhile in core
structures too, this is not the first one at all.

Given that the void * is only trouble since gcc can't warn you if you

Given all that it doesn't make sense to put the docs for these next to
specific helpers. Instead extract them into a new header file and
section in the docbook, and add references to them everywhere.

Unfortunately kernel-doc complains when an include directive doesn't
find anything (and it does by dumping crap into the output file). We
have to remove the now empty includes to avoid that, instead of leaving
them in for future proofing.

v2: More OCD in ordering functions.

v3: Spelling plus collate copyright headers properly.

Daniel Vetter b516a9efb7 drm: Move LEAVE/ENTER_ATOMIC_MODESET to fbdev helpers
This is only used for kgdb (and previously panic) handlers in
the fbdev emulation, so belongs there.

Note that this means we'll leave behind a forward declaration, but
once all the helper vtables are consolidated (in the next patch) that
will make more sense.

v2: fixup radone/amdgpu.

Daniel Vetter 264d6970e1 drm: Polish fbdev helper struct docs
Mostly this is just adding extensive docs for the callbacks, but also
a few other additions.

v2: Use FIXME comments to annotate helper hooks that should be
replaced.

v3: Small nits (Thierry).

Eric Anholt 10028c5ab1 drm: Create a driver hook for allocating GEM object structs.
The CMA helpers had no way for a driver to extend the struct with its
own fields.  Since the CMA helpers are mostly "Allocate a
drm_gem_cma_object, then fill in a few fields", it's hard to write as
pure helpers without passing in a driver callback for the allocate
step.

Back merge tag 'v4.4-rc4' into drm-next

We've picked up a few conflicts and it would be nice
to resolve them before we move onwards.
