f1b8859e8d radeon: insert 10ms sleep in dce5_crtc_load_lut
[ Upstream commit ec3d65082d ]

Per at least one tester this is enough magic to recover the regression
introduced for some people (but not all) in

commit b8e2b0199c
Author: Peter Rosin <peda@axentia.se>
Date:   Tue Jul 4 12:36:57 2017 +0200

    drm/fb-helper: factor out pseudo-palette

which for radeon had the side-effect of refactoring out a seemingly
redudant writing of the color palette.

10ms in a fairly slow modeset path feels like an acceptable form of
duct-tape, so maybe worth a shot and see what sticks.

ae2f1cd6a3 drm/nouveau/disp/nv50-: prevent oops when no channel method map provided
[ Upstream commit 0e6176c6d2 ]

The implementations for most channel types contains a map of methods to
priv registers in order to provide debugging info when a disp exception
has been raised.

This info is missing from the implementation of PIO channels as they're
rather simplistic already, however, if an exception is raised by one of
them, we'd end up triggering a NULL-pointer deref.  Not ideal...

1899747eb7 drm/mediatek: handle events when enabling/disabling crtc
[ Upstream commit 411f5c1eac ]

The driver currently handles vblank events only when updating planes on
an already enabled CRTC. The atomic update API however allows requesting
an event when enabling or disabling a CRTC. This currently leads to
event objects being leaked in the kernel and to events not being sent
out. Fix it.

it should set ret in both the success and fail path.

ff19c8c6ea drm/amd/display: Retrain dongles when SINK_COUNT becomes non-zero
[ Upstream commit 3eb6d7aca5 ]

[WHY]
Two years ago the patch referenced by the Fixes tag stopped running
dp_verify_link_cap_with_retries during DP detection when the reason
for the detection was a short-pulse interrupt. This effectively meant
that we were no longer doing the verify_link_cap training on active
dongles when their SINK_COUNT changed from 0 to 1.

A year ago this was partly remedied with:
commit 80adaebd2d ("drm/amd/display: Don't skip link training for empty dongle")

This made sure that we trained the dongle on initial hotplug (without
connected downstream devices).

This is all fine and dandy if it weren't for the fact that there are
some dongles on the market that don't like link training when SINK_COUNT
is 0 These dongles will in fact indicate a SINK_COUNT of 0 immediately
after hotplug, even when a downstream device is connected, and then
trigger a shortpulse interrupt indicating a SINK_COUNT change to 1.

In order to play nicely we will need our policy to not link train an
active DP dongle when SINK_COUNT is 0 but ensure we train it when the
SINK_COUNT changes to 1.

[HOW]
Call dp_verify_link_cap_with_retries on detection even when the detection
is triggered from a short pulse interrupt.

With this change we can also revert this commit which we'll do in a separate
follow-up change:
commit 80adaebd2d ("drm/amd/display: Don't skip link training for empty dongle")

5d358e7e2b drm/gma500: Fixup fbdev stolen size usage evaluation
[ Upstream commit fd1a5e521c ]

psbfb_probe performs an evaluation of the required size from the stolen
GTT memory, but gets it wrong in two distinct ways:
- The resulting size must be page-size-aligned;
- The size to allocate is derived from the surface dimensions, not the fb
  dimensions.

When two connectors are connected with different modes, the smallest will
be stored in the fb dimensions, but the size that needs to be allocated must
match the largest (surface) dimensions. This is what is used in the actual
allocation code.

Fix this by correcting the evaluation to conform to the two points above.
It allows correctly switching to 16bpp when one connector is e.g. 1920x1080
and the other is 1024x768.

4ecba33ec8 drm/dp_mst: Remove VCPI while disabling topology mgr
[ Upstream commit 64e62bdf04 ]

[Why]

This patch is trying to address the issue observed when hotplug DP
daisy chain monitors.

e.g.
src-mstb-mstb-sst -> src (unplug) mstb-mstb-sst -> src-mstb-mstb-sst
(plug in again)

Once unplug a DP MST capable device, driver will call
drm_dp_mst_topology_mgr_set_mst() to disable MST. In this function,
it cleans data of topology manager while disabling mst_state. However,
it doesn't clean up the proposed_vcpis of topology manager.
If proposed_vcpi is not reset, once plug in MST daisy chain monitors
later, code will fail at checking port validation while trying to
allocate payloads.

When MST capable device is plugged in again and try to allocate
payloads by calling drm_dp_update_payload_part1(), this
function will iterate over all proposed virtual channels to see if
any proposed VCPI's num_slots is greater than 0. If any proposed
VCPI's num_slots is greater than 0 and the port which the
specific virtual channel directed to is not in the topology, code then
fails at the port validation. Since there are stale VCPI allocations
from the previous topology enablement in proposed_vcpi[], code will fail
at port validation and reurn EINVAL.

[How]

Clean up the data of stale proposed_vcpi[] and reset mgr->proposed_vcpis
to NULL while disabling mst in drm_dp_mst_topology_mgr_set_mst().

1f1611dc1f drm: atmel-hlcdc: enable clock before configuring timing engine
[ Upstream commit 2c1fb9d86f ]

Changing pixel clock source without having this clock source enabled
will block the timing engine and the next operations after (in this case
setting ATMEL_HLCDC_CFG(5) settings in atmel_hlcdc_crtc_mode_set_nofb()
will fail). It is recomended (although in datasheet this is not present)
to actually enabled pixel clock source before doing any changes on timing
enginge (only SAM9X60 datasheet specifies that the peripheral clock and
pixel clock must be enabled before using LCD controller).

../drivers/gpu/drm/msm/disp/mdp4/mdp4_dsi_encoder.c:124:3: warning:
misleading indentation; statement is not part of the previous 'if'
[-Wmisleading-indentation]
         mdp4_crtc_set_config(encoder->crtc,

previous statement is here
        if (mdp4_dsi_encoder->enabled)
        ^

This warning occurs because there is a space after the tab on this line.
Remove it so that the indentation is consistent with the Linux kernel
coding style and clang no longer warns.

abc51506fc drm/amd/dm/mst: Ignore payload update failures
commit 58fe03d6de upstream.

Disabling a display on MST can potentially happen after the entire MST
topology has been removed, which means that we can't communicate with
the topology at all in this scenario. Likewise, this also means that we
can't properly update payloads on the topology and as such, it's a good
idea to ignore payload update failures when disabling displays.
Currently, amdgpu makes the mistake of halting the payload update
process when any payload update failures occur, resulting in leaving
DC's local copies of the payload tables out of date.

This ends up causing problems with hotplugging MST topologies, and
causes modesets on the second hotplug to fail like so:

Note as well, I have only been able to reproduce this on setups with 2
MST displays.

Changes since v1:
* Don't return false when part 1 or part 2 of updating the payloads
  fails, we don't want to abort at any step of the process even if
  things fail

41be0c3295 Revert "drm/sun4i: dsi: Change the start delay calculation"
[ Upstream commit a00d17e0a7 ]

This reverts commit da676c6aa6.

The original commit adds a start parameter to the calculation of the
start delay according to some old BSP versions from Allwinner. However,
there're two ways to add this delay -- add it in DSI controller or add
it in the TCON. Add it in both controllers won't work.

The code before this commit is picked from new versions of BSP kernel,
which has a comment for the 1 that says "put start_delay to tcon". By
checking the sun4i_tcon0_mode_set_cpu() in sun4i_tcon driver, it has
already added this delay, so we shouldn't repeat to add the delay in DSI
controller, otherwise the timing won't match.

6fab6dbff4 drm/radeon: fix bad DMA from INTERRUPT_CNTL2
[ Upstream commit 62d91dd285 ]

The INTERRUPT_CNTL2 register expects a valid DMA address, but is
currently set with a GPU MC address.  This can cause problems on
systems that detect the resulting DMA read from an invalid address
(found on a Power8 guest).

Instead, use the DMA address of the dummy page because it will always
be safe.

2e7d73cb22 drm/msm/dsi: Implement reset correctly
[ Upstream commit 78e31c4226 ]

On msm8998, vblank timeouts are observed because the DSI controller is not
reset properly, which ends up stalling the MDP.  This is because the reset
logic is not correct per the hardware documentation.

The documentation states that after asserting reset, software should wait
some time (no indication of how long), or poll the status register until it
returns 0 before deasserting reset.

wmb() is insufficient for this purpose since it just ensures ordering, not
timing between writes.  Since asserting and deasserting reset occurs on the
same register, ordering is already guaranteed by the architecture, making
the wmb extraneous.

Since we would define a timeout for polling the status register to avoid a
possible infinite loop, lets just use a static delay of 20 ms, since 16.666
ms is the time available to process one frame at 60 fps.

66779aa306 drm/fb-helper: generic: Fix setup error path
[ Upstream commit 6e1490cf43 ]

If register_framebuffer() fails during fbdev setup we will leak the
framebuffer, the GEM buffer and the shadow buffer for defio. This is
because drm_fb_helper_fbdev_setup() just calls drm_fb_helper_fini() on
error not taking into account that register_framebuffer() can fail.

Since the generic emulation uses DRM client for its framebuffer and
backing buffer in addition to a shadow buffer, it's necessary to open code
drm_fb_helper_fbdev_setup() to properly handle the error path.

Error cleanup is removed from .fb_probe and is handled by one function for
all paths.

035e304f95 drm/dp_mst: Skip validating ports during destruction, just ref
[ Upstream commit c54c7374ff ]

Jerry Zuo pointed out a rather obscure hotplugging issue that it seems I
accidentally introduced into DRM two years ago.

Pretend we have a topology like this:

|- DP-1: mst_primary
   |- DP-4: active display
   |- DP-5: disconnected
   |- DP-6: active hub
      |- DP-7: active display
      |- DP-8: disconnected
      |- DP-9: disconnected

If we unplug DP-6, the topology starting at DP-7 will be destroyed but
it's payloads will live on in DP-1's VCPI allocations and thus require
removal. However, this removal currently fails because
drm_dp_update_payload_part1() will (rightly so) try to validate the port
before accessing it, fail then abort. If we keep going, eventually we
run the MST hub out of bandwidth and all new allocations will start to
fail (or in my case; all new displays just start flickering a ton).

We could just teach drm_dp_update_payload_part1() not to drop the port
ref in this case, but then we also need to teach
drm_dp_destroy_payload_step1() to do the same thing, then hope no one
ever adds anything to the that requires a validated port reference in
drm_dp_destroy_connector_work(). Kind of sketchy.

So let's go with a more clever solution: any port that
drm_dp_destroy_connector_work() interacts with is guaranteed to still
exist in memory until we say so. While said port might not be valid we
don't really care: that's the whole reason we're destroying it in the
first place! So, teach drm_dp_get_validated_port_ref() to use the all
mighty current_work() function to avoid attempting to validate ports
from the context of mgr->destroy_connector_work. I can't see any
situation where this wouldn't be safe, and this avoids having to play
whack-a-mole in the future of trying to work around port validation.
