Peter Ujfalusi 49efffc7fb drm: Add drm_mode_config->normalize_zpos boolean
Instead of drivers duplicating the drm_atomic_helper_check() code to be
able to normalize the zpos they can use the normalize_zpos flag to let the
drm core to do it.

Andy Shevchenko 7056a2bccc drm/dp/mst: Fix off-by-one typo when dump payload table
It seems there is a classical off-by-one typo from the beginning
when commit

  ad7f8a1f9c ("drm/helper: add Displayport multi-stream helper (v0.6)")

introduced a new helper.

Fix a typo by introducing a macro constant.

Ville Syrjälä 8017e422af drm/scdc-helper: Convert errors into debug messages
Since we may attempt to reconfigure SCDC when the sink has already been
disconnected we probably shouldn't scare the user with errors in dmesg
that are 100% expected in that case. Just leave it up to the caller
whether to print an error message or not, and just output debug
messages from the helper itself.

Daniel Vetter 3903117609 drm/gem: Document that handle_create must be the last step
It published the gem object to userspace, by that point other threads
can guess the id and start using it. And gem IDs are _very_ easy to
guess (it's just an idr).

Since gem objects is the only thing we allow drivers to create
themselves (all the kms/prime/syncobj stuff is handled by the core) no
other functions seem to be in need of this clarification.

Motivated by reviewing the xen-front kms driver.

Dave Airlie 19c800caa6 drm/tegra: Changes for v4.17-rc1
This fixes mmap() for fbdev devices by providing a custom implementation
 based on the KMS variant. This is a fairly exotic case these days, hence
 why it is not flagged for stable.
 
 There is also support for dedicating one of the overlay planes to serve
 as a hardware cursor on older Tegra that did support hardware cursors
 but not RGBA formats for it.
 
 Planes will now also export the IN_FORMATS property by supporting the
 various block-linear tiling modifiers for RGBA pixel formats.
 
 Other than that, there's a bit of cleanup of DMA API abuse, use of the
 private object infrastructure for global state (rather than subclassing
 atomic state objects) and an implementation of ->{begin,end}_cpu_access
 callbacks for PRIME exported buffers, which allow users to perform cache
 maintenance on these buffers.

drm/sun4i: backend: Support YUV planes
Now that we have the guarantee that we will have only a single YUV plane,
actually support them. The way it works is not really straightforward,
since we first need to enable the YUV mode in the plane that we want to
setup, and then we have a few registers to setup the YUV buffer and
parameters.

We also need to setup the color correction to actually have something
displayed.

drm/sun4i: Add support for A80 TCONs
The Allwinner A80 SoC has 2 documented TCONs. The display pipeline
diagram from the user manual shows a third TCON, but it's missing
an interrupt line, and its registers are not explained either.
It's also not used in Allwinner's vendor BSP.

The first TCON only has channel 0, for LCD panel output. The TCON
hardware setup is peculiar in that the eDP reset must also be
deasserted to allow access to the TCON. How the eDP module is wired
in the SoC itself is never explained.

The second TCON only has channel 1, and its output is connected to
the HDMI encoder block.

This patch adds a "needs_edp_reset" field to the tcon quirks structure,
and adds quirks and compatible strings for the 2 documented TCONs.

drm/sun4i: Add DT binding for Detail Enhancement Unit in Allwinner A80 SoC
The display pipeline on the A80 SoC has what is called the Detail
Enhancement Unit, or DEU for short, block in between the display
frontend and backend. This unit can sharpen images in both luma
and chroma channels. It seems to also do colorspace conversion.

This patch adds the device tree binding for this hardware block.

drm/sun4i: Add compatible strings for A80 TCONs
The A80 has 2 or 3 TCONs. The documentation and vendor kernel are very
vague about the third TCON, to the point that it might not exist.

In the documentation, the first TCON is missing channel 1, and the
second is missing channel 0. However the vendor kernel seems to be
able to use them regardless. Here we model them like the old TCONs.

An oddity is that TCON0 requires the reset control for the eDP block
to be deasserted, for any register access to stick.

This patch adds compatible strings for TCON0 and TCON1, with TCON0
requiring an extra "edp" reset control.

Joe Perches db87086492 drm: Reduce object size of DRM_DEV_<LEVEL> uses
These macros are similar to the DRM_<LEVEL> with the addition
of a struct device * to the arguments.

Convert the single drm_dev_printk function into 2 separate functions.
drm_dev_printk with a KERN_<LEVEL> * for generic use and drm_dev_dbg
for conditional masked use.

Remove the __func__ argument and use __builtin_return_address(0) to be
similar to the DRM_<LEVEL> macros uses.

Convert the DRM_DEV_<LEVEL> macros to remove now unnecessary arguments
and use a consistent style.

These macros are rarely used in the generic gpu/drm code so the code
size does not change much for a defconfig, but when more drivers are
enabled, there is ~4k savings.

Many of these macros have no existing use at all.

Rob Clark f9cb8d8d83 drm/msm/mdp5: rework CTL START signal handling
For DSI cmd-mode and writeback, we need to write the CTL's START
register to kick things off, but we only want to do that once both
the encoder and the crtc have a chance to write their corresponding
flush bits.  The difficulty is that when there is a full modeset
(ie. encoder state has changed) we want to defer the start until
encoder->enable().  But if only plane's have changed, we want to do
this from crtc->commit().

The start_mask was a previous attempt to handle this, but it didn't
really do the right thing since atomic conversion.

Instead track in the crtc state that the start should be deferred,
set to try from encoder's (or in future writeback's) atomic_check().
This way the state is part of the atomic state, and rollback can
work properly if an atomic test fails.

Bjorn Andersson 79d57bf6fa drm/msm: Trigger fence completion from GPU
Interrupt commands causes the CP to trigger an interrupt as the command
is processed, regardless of the GPU being done processing previous
commands. This is seen by the interrupt being delivered before the
fence is written on 8974 and is likely the cause of the additional
CP_WAIT_FOR_IDLE workaround found for a306, which would cause the CP to
wait for the GPU to go idle before triggering the interrupt.

Instead we can set the (undocumented) BIT(31) of the CACHE_FLUSH_TS
which will cause a special CACHE_FLUSH_TS interrupt to be triggered from
the GPU as the write event is processed.

Add CACHE_FLUSH_TS to the IRQ masks of A3xx and A4xx and remove the
workaround for A306.

Gustavo A. R. Silva 0126b23c55 drm/vc4_validate: Remove VLA usage
In preparation to enabling -Wvla, remove VLA. In this particular
case use macro ARRAY_SIZE so the length of array _bo_ can be
computed at preprocessing time.

The use of stack Variable Length Arrays needs to be avoided, as they
can be a vector for stack exhaustion, which can be both a runtime bug
or a security flaw. Also, in general, as code evolves it is easy to
lose track of how big a VLA can get. Thus, we can end up having runtime
failures that are hard to debug.

Also, fixed as part of the directive to remove all VLAs from
