Currently packed pixel modes in MHL2 can't be displayed. The device
automatically recognizes output format, so setting format other than
RGB causes failure. Fix it by writing proper values to registers.
Tested on MHL1 and MHL2 using various vendors' dongles both in
DVI and HDMI mode.

This reverts commit 2c17a4368aad2b88b68e4390c819e226cf320f70.
The offending commit triggers a run-time fault when accessing the panel
element of the sun4i_tcon structure when no such panel is attached.
It was apparently assumed in said commit that a panel is always used with
the TCON. Although it is often the case, this is not always true.
For instance a bridge might be used instead of a panel.
This issue was discovered using an A13-OLinuXino, that uses the TCON
in RGB mode for a simple DAC-based VGA bridge.

MHL bridge is usually connected to TV via MHL dongle. Currently plugging
HDMI cable to dongle is handled improperly.
Fix it by splitting connecting of a dongle and a HDMI cable. The driver
should now handle unplugging a sink from a dongle and plugging a
different sink with new edid.
Tested on MHL1, MHL2 and MHL3 using various vendors' dongles both in
DVI and HDMI mode.

HSIC initialization was taken from the vendor code. HSIC in MHL circuit
is not connected, so it is not possible to test it. Tests prove that
without HSIC the device works well. Therefore it can be removed.

The vendor code waits for infoframe to detect video mode set by source.
We do not need to follow this pattern, because video mode information is
provided by drm core. As a result most of the infoframe handling
code can be removed.
Start transmission immediately after detecting stream on HDMI lines
in irq_scdt() function without waiting for infoframe interrupt.

Buffer overflow error should not occur, as mode_fixup() callback
filters pixel clock value and it should never exceed 600000. However,
current implementation is not obviously safe and relies on
implementation of mode_fixup().
Make 'i' variable never reach unsafe value in order to avoid buffer

The SF and clipper units mishandle the provoking vertex in some cases,
which can cause misrendering with shaders that use flat shaded inputs.
There are chicken bits in 3D_CHICKEN3 (for SF) and FF_SLICE_CHICKEN
(for the clipper) that work around the issue. These registers are
unfortunately not part of the logical context (even the power context),
and so we must reload them every time we start executing in a context.

If client is smart or lucky enough to create a new context
after each hang, our context banning mechanism will never
catch up, and as a result of that it will be saved from
client banning. This can result in a never ending streak of
gpu hangs caused by bad or malicious client, preventing
access from other legit gpu clients.
Fix this by always incrementing per client ban score if
it hangs in short successions regardless of context ban
scoring. The exception are non bannable contexts. They remain
detached from client ban scoring mechanism.

While Bspec doesn't list a specific sequence for turning off the DP port
on g4x we are getting an underrun if the port is disabled in the
.disable() hook. Looks like the pipe stops when the port stops, and by
that time the plane disable may not have completed yet. Also the plane(s)
seem to end up in some wonky state when this happens as they also signal
another underrun immediately after we turn them back on during the next
enable sequence.
We could add a vblank wait in .disable() to avoid wedging the planes,
but I assume we're still tripping up the pipe in some way. So it seems
better to me to just follow the ILK+ sequence and turn off the DP port
in .post_disable() instead. This sequence doesn't seem to suffer from
this problem. Could be it was always the intended sequence for DP and
the gen4 bspec was just never updated to include it.
Originally we used the bad sequence even on ilk+, but I changed that
in commit 08aff3fe26ae ("drm/i915: Move DP port disable to post_disable
for pch platforms") as it was causing issues on those platforms as well.
I left out g4x then only because I didn't have the hardware to test it.
Now that I do it's fairly clear that the ilk+ sequence is also the
right choice for g4x.

On i965/g4x IIR is edge triggered. So in order for IIR to notice that
there is still a pending interrupt we have to force and edge in ISR.
For the ISR/IIR pipe event bits we can do that by temporarily
clearing all the PIPESTAT enable bits when we ack the status bits.
This will force the ISR pipe event bit low, and it can then go back
high when we restore the PIPESTAT enable bits.
This avoids the following race:
1. stat = read(PIPESTAT)
2. an enabled PIPESTAT status bit goes high
3. write(PIPESTAT, enable|stat);
4. write(IIR, PIPE_EVENT)
The end result is IIR==0 and ISR!=0. This can lead to nasty
vblank wait/flip_done timeouts if another interrupt source
doesn't trick us into looking at the PIPESTAT status bits despite
the IIR PIPE_EVENT bit being low.
Before i965 IIR was level triggered so this problem can't actually
happen there. And curiously VLV/CHV went back to the level triggered
scheme as well. But for simplicity we'll use the same i965/g4x
compatible code for all platforms.

When encountering a connector with the scaling mode property both
intel and modesetting ddxs sometimes add tons of DBLSCAN modes
to the output's mode list. The idea presumably being that since the
output will be going through the panel fitter anyway we can pretend
to use any kind of mode.
Sadly that means we can't reject user modes with the DBLSCAN flag
until we know whether we're going to be using the panel's native
mode or the user mode directly. Doing otherwise means X clients using
xf86vidmode/xrandr will get a protocol error (and often self
terminate as a result) when the kernel refuses to use the requested
mode with the DBLSCAN flag.
To undo the regression we'll move the DBLSCAN checks into the
connector->mode_valid() and encoder->compute_config() hooks.

We special case the position of the batch within the GTT to prevent
negative self-relocation deltas from underflowing. However, that
restriction is being applied after a trial pin of the batch in its
current position. Thus we are not rejecting an invalid location if the
batch has been used before, leading to an assertion if we happen to need
to rearrange the entire payload. In the worst case, this may cause a GPU
hang on gen7 or perhaps missing state.

We've had a number of users report failures to detect and light up
display with DC with LVDS and VGA. These connector types are not
currently supported with DC. I'd like to add support but unfortunately
don't have a system with LVDS or VGA available.
In order not to cause regressions we should probably fallback to the
non-DC driver for ASICs that support VGA and LVDS.
These ASICs are:
* Bonaire
* Kabini

"qxl_bo_unref" may sleep, but calling "qxl_release_map" causes
"preempt_disable()" to be called and "preempt_enable()" isn't called
until "qxl_release_unmap" is used. Move the call to "qxl_bo_unref" out
from in between the two to avoid sleeping from an atomic context.
This issue can be demonstrated on a kernel with CONFIG_LOCKDEP=y by
creating a VM using QXL, using a desktop environment using Xorg, then
moving the cursor on or off a window.

When unplugging a hotpluggable DRM device we first unregister it
with drm_dev_unregister and then set drm_device.unplugged flag which
is used to mark device critical sections with drm_dev_enter()/
drm_dev_exit() preventing access to device resources that are not
available after the device is gone.
But drm_dev_unregister may lead to hotplug uevent(s) fired to
user-space on card and/or connector removal, thus making it possible
for user-space to try accessing a disconnected device.
Fix this by first making sure device is properly marked as
disconnected and only then unregister it.

Ctxdmas for cursors from all heads are setup in the core channel, and due
to us tracking allocated handles per-window, we were failing with -EEXIST
on multiple-head setups trying to allocate duplicate handles.
The cursor code is hardcoded to use the core channel vram ctxdma already,
so just skip ctxdma allocation for cursor fbs to fix the issue.

As hw required, soc clock must large than mclk, So we set max soc
clock to OD Max Memory clk.
But on workstation, vbios do not support OD feature, the OD max memory
clock is equal to 0. In this case, driver can support underclocking.
and set od max memory clock to the value in highest memory dpm level.
So the od max memory clock should be less than highest soc clock.
and driver should not change the soc clock.

Fixes stale buffer object (bo) usage for cursor plane
Cursor plane's bo operations are handled in DC code.
Currently, atomic_commit() does not handle bo operations
for cursor plane, as a result the bo assigned for cursor
plane in dm_plane_helper_prepare_fb() is not coherent
with the updates to the same made in dc code.This mismatch
leads to "bo" corruption and hence crashes during S3 entry.
This patch cleans up the code which was added as a hack
for 4.9 version only.

So, unfortunately I recently made the discovery that in the upstream
kernel, the only reason that amdgpu is not currently suffering from
issues with runtime PM putting the GPU into suspend while it's driving
displays is due to the fact that on most prime systems, we have sound
devices associated with the GPU that hold their own runtime PM ref for
the GPU.
What this means however, is that in the event that there isn't any kind
of sound device active (which can easily be reproduced by building a
kernel with sound drivers disabled), the GPU will fall asleep even when
there's displays active. This appears to be in part due to the fact that
amdgpu has not actually ever relied on it's rpm_idle() function to be
the only thing keeping it running, and normally grabs it's own power
references whenever there are displays active (as can be seen with the
original pre-DC codepath in amdgpu_display_crtc_set_config() in
amdgpu_display.c). This means it's very likely that this bug was
introduced during the switch over the DC.
So to fix this, we start grabbing runtime PM references every time we
enable a previously disabled CRTC in atomic_commit_tail(). This appears
to be the correct solution, as it matches up with what i915 does in
i915/intel_runtime_pm.c.
The one sideaffect of this is that we ignore the variable that the
pre-DC code used to use for tracking when it needed runtime PM refs,
adev->have_disp_power_ref. This is mainly because there's no way for a
driver to tell whether or not all of it's CRTCs are enabled or disabled
when we've begun committing an atomic state, as there may be CRTC
commits happening in parallel that aren't contained within the atomic
state being committed. So, it's safer to just get/put a reference for
each CRTC being enabled or disabled in the new atomic state.

gfx_off_control handler
Patch 9667849bbb8d: "drm/amd/powerplay: add control gfxoff enabling in late
init" from Mar 13, 2018, leads to the following static checker warning:
drivers/gpu/drm/amd/amdgpu/../powerplay/amd_powerplay.c:194
pp_late_init()
error: we previously assumed 'hwmgr' could be null (see line 185)
drivers/gpu/drm/amd/amdgpu/../powerplay/amd_powerplay.c
This patch fixes the warning to add hwmgr checking.
