It looks like the BOE panel FW didn't ack the DPCD600 signal from the
host device, this will cause the panel to hang on the startup display.
The root cause is that we use the fast link mode when we enter and
exit PSR, the issue is gone if we switch from the fast link to main
link mode.

So it looks like the code is trying to pick between the passed in fb and
crtc->primary->fb based on that funky 'bool atomic'. But later it will
mix uses of both drm_fb (which was picked by the aforementioned logic)
and crtc->primary->fb. So looks like a bug to me. Let's make it use
drm_fb only.

- Five more DocBook template files converted to Sphinx. Only 27 to go...
Lots of plain-text files have also been converted and integrated.
- Images in binary formats have been replaced with more source-friendly

- Various bits of organizational work, including the renaming of various

- New documentation for the device_link mechanism.
...and, of course, lots of typo fixes and small updates.

Merge tag 'docs-4.10' of git://git.lwn.net/linux into drm-misc-next
Backmerge the docs-next branch from Jon into drm-misc so that we can
apply the dma-buf documentation cleanup patches. Git found a conflict
where there was none because both drm-misc and docs had identical
patches to clean up file rename issues in the rst include directives.
Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
It's deprecated and only should be used by drivers which still use
drm_platform_init, not by anyone else.
And indeed it's entirely unused and can be nuked.
This required a bit more fudging, but I guess kirin_dc_ops really
wants to operate on the platform_device, not something else. Also
bonus points for implementing abstraction, and then storing the vfunc
in a global variable.
v2: Don't break the build soooo badly :(
Note that the cleanup function is a bit confused: ade_data was never
set as drvdata, and calling drm_crtc_cleanup directly is a bug - this
is called indirectly through drm_mode_config_cleanup, which calls into
crtc->destroy, which already has the call to drm_crtc_cleanup. Which
means we can just nuke it.
Note this is the 2nd attempt after the first one failed and had to be
reverted again in

With the last round of changes all ioctls called by modern drivers now
have their own locking. Everything else is only allowed for legacy
drivers and hence the lack of locking doesn't matter.
One exception is nouveau, due to the DRIVER_KMS_LEGACY_CONTEXT flag.
But that only works its magic on the context and bufs ioctls. And
drm_bufs.c is protected with dev->struct_mutex, and drm_context.c by
the same and dev->ctxlist_mutex. That should be all safe, and we can
finally mandata drm-bkl-less ioctls for everyone!

It only updates per-file feature flags. And all the ioctl which change
behaviour depending upon these flags (they're all kms features) do
_not_ hold the BKL. Therefor this is pure cargo-cult and can be
removed.
Note that there's a risk that the ioctl will behave inconsistently
when userspace is racing with itself, but that's ok. The only thing
it's not allowed to do is oops the kernel, and from an audit all
places are safe.
v2: Clarify that the inconsistency is only when userspace races

No one looks at the major/minor versions except the unique/busid
stuff. If we protect that with the master_mutex (since it also affects
the unique of each master, oh well) we can mark these two IOCTL with
DRM_UNLOCKED.
While doing this I realized that the comment for the magic_map is
outdated, I've forgotten to update it in:

Merge tag 'drm-vc4-next-2016-12-09' of https://github.com/anholt/linux into drm-next
This pull request brings in VEC (TV-out) support for vc4, along with a
pageflipping race fix.
* tag 'drm-vc4-next-2016-12-09' of https://github.com/anholt/linux:
drm/vc4: Don't use drm_put_dev
drm/vc4: Document VEC DT binding
drm/vc4: Add support for the VEC (Video Encoder) IP
drm: Add TV connector states to drm_connector_state
drm: Turn DRM_MODE_SUBCONNECTOR_xx definitions into an enum
drm/vc4: Fix ->clock_select setting for the VEC encoder
drm/vc4: Fix race between page flip completion event and clean-up
The Apple GMUX is the one managing the backlight, so there is no need for
Nouveau to register its own backlight interface.
v2: Do not split information message on two lines as it prevents from grepping
it, as pointed out by Lukas Wunner
v3: Add a missing end-of-line character to the printed message

Currently, every backlight interface created by Nouveau uses the same name,
nv_backlight. This leads to a sysfs warning as it tries to create an already
existing folder. This patch adds a incremented number to the name, but keeps
the initial name as nv_backlight, to avoid possibly breaking userspace; the
second interface will be named nv_backlight1, and so on.
Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=86539
v2:
* Switch to using ida for generating unique IDs, as suggested by Ilia Mirkin;
* Allocate backlight name on the stack, as suggested by Ilia Mirkin;
* Move `nouveau_get_backlight_name()` to avoid forward declaration, as
suggested by Ilia Mirkin;
* Fix reference to bug report formatting, as reported by Nick Tenney.
v3:
* Define a macro for the size of the backlight name, to avoid defining
it multiple times;
* Use snprintf in place of sprintf.
v4:
* Do not create similarly named interfaces when reaching the maximum
amount of unique names, but fail instead, as pointed out by Lukas Wunner

TTM was changed a while back to allow for pipelining of buffer moves, and
part of this was the removal of waiting for a BO to idle before calling
move(), placing the responsibility on the driver to do this if required.
That's all well and good, except, we make use of move_notify() to handle
mapping/unmapping from the GPU VMM as move() isn't called on all paths.
This commit adds a wait before unmapping from a VMM in move_notify(), to
prevent GPU page faults where a buffer is still being accessed.

This has been on the TODO list for a while now, recovering from things
such as attempting to execute a push buffer or touch a semaphore in an
unmapped memory area.
The only thing required on the HW side here is that the offending
channel is removed from the runlist, and *not* a full reset of PFIFO.
This used to be a bit messier to handle before the rework to make use
of engine topology info, but is apparently now trivial.

Looping twice when we can do it once is silly. Also use a consistent
style. Note that there's a good race with the connector list walking,
since that is no longer protected by mode_config.mutex. But that's for
a later patch to fix.
v2: Actually try to not blow up, somehow I lost the hunk that checks
we don't copy too much. Noticed by Chris.
v3:
- squash all drm_mode_getresources cleanups into one
- use consistent style for walking objects (Chris)
v4:
- Use u64_to_user_ptr (Chris)
- Don't forget to copy the last connector (Chris)
v5: Chris was right ...
