Some atomic properties are common between the various kinds of
connectors, for example a lot of them use panel fitting mode.
It makes sense to put a lot of it in a common place, so each
connector can use it while they're being converted.
Implement the properties required for the connectors:
- scaling mode property
- force audio property
- broadcast rgb
- aspect ratio
While at it, make clear that intel_digital_connector_atomic_get_property
is a hack that has to be removed when all connector properties
are converted to atomic.
Changes since v1:
- Scaling mode and aspect ratio are partly handled in core now.
Changes since v2:
- Split out the scaling mode / aspect ratio changes to a preparation
patch.
- Use mode_changed for panel fitter, changes to this property
are checked by fastset.
- Allowed_scaling_modes is removed, handled through core now.

The first step in converting connector properties to atomic is
wiring up the atomic state. We're still not completely supoprting
the scaling mode in the atomic case, but this is the first step
towards it.

Move cursor_base, cursor_cntl, and cursor_size from intel_crtc
into intel_plane so that we don't need the crtc for cursor stuff
so much.
Also entirely nuke cursor_addr which IMO doesn't provide any benefit
since it's not actually used by the cursor code itself. I'm not 100%
sure what the SKL+ DDB is code is after by looking at cursor_addr so
I just make it do its checks unconditionally. If that's not correct
then we should likely replace it with somehting like
plane_state->visible.

Implement proper two stage watermark programming for g4x. As with
other pre-SKL platforms, the watermark registers aren't double
buffered on g4x. Hence we must sequence the watermark update
carefully around plane updates.
The code is quite heavily modelled on the VLV/CHV code, with some
fairly significant differences due to the different hardware
architecture:
* g4x doesn't use inverted watermark values
* CxSR actually affects the watermarks since it controls memory self
refresh in addition to the max FIFO mode
* A further HPLL SR mode is possible with higher memory wakeup
latency
* g4x has FBC2 and so it also has FBC watermarks
* max FIFO mode for primary plane only (cursor is allowed, sprite is not)
* g4x has no manual FIFO repartitioning
* some TLB miss related workarounds are needed for the watermarks
Actually the hardware is quite similar to ILK+ in many ways. The
most visible differences are in the actual watermakr register
layout. ILK revamped that part quite heavily whereas g4x is still
using the layout inherited from earlier platforms.
Note that we didn't previously enable the HPLL SR on g4x. So in order
to not introduce too many functional changes in this patch I've not
actually enabled it here either, even though the code is now fully
ready for it. We'll enable it separately later on.

If link training at a link rate optimal for a particular
mode fails during modeset's atomic commit phase, then we
let the modeset complete and then retry. We save the link rate
value at which link training failed, update the link status property
to "BAD" and use a lower link rate to prune the modes. It will redo
the modeset on the current mode at lower link rate or if the current
mode gets pruned due to lower link constraints then, it will send a
hotplug uevent for userspace to handle it.
This is also required to pass DP CTS tests 4.3.1.3, 4.3.1.4,
4.3.1.6.
This patch is a resend of the original commit id (233ce881dd91fb
"drm/i915: Implement Link Rate fallback on Link training failure")
which got reverted in this commit id (afc1ebf4562a14 Revert
"drm/i915: Implement Link Rate fallback on Link training failure")
due to CI failures.
After investigating the CI failures it was found that these
were essentially the failures which were always there but hidden because
they used to be DRM_DEBUG_KMS messages for link failures so never got
caught by CI. But now this patch actually throws DRM_ERROR if the link
training fails at RBR and 1 lane. So it caught these link train failures.
There were two failures:
1. On SKL 6700k this was because the machine in CI lab is a SKL desktop
without eDP on Port A. But our VBT initialization code in the driver writes
VBT defaults in a way that it always sets DP flag on Port A and this does
not get cleared after parsing the VBT outputs. This has been fixed in
commit id (bb1d132935c2f8 "drm/i915/vbt: split out defaults that are set
when there is no VBT) and (665788572c6410b "drm/i915/vbt: don't propagate
errors from intel_bios_init())
2. On ILK-650 desktop - This was happening because of a bad monitor desktop
combination. I switched the monitor in the CI lab and that helped get rid
of the link failures on ILK system.
v10:
* Rebase on drm-tip and resend after revert
v9:
* Use the trimmed max values of link rate/lane count based on
link train fallback (Daniel Vetter)
v8:
* Set link_status to BAD first and then call mode_valid (Jani Nikula)
v7:
Remove the redundant variable in previous patch itself
v6:
* Obtain link rate index from fallback_link_rate using
the helper intel_dp_link_rate_index (Jani Nikula)
* Include fallback within intel_dp_start_link_train (Jani Nikula)
v5:
* Move set link status to drm core (Daniel Vetter, Jani Nikula)
v4:
* Add fallback support for non DDI platforms too
* Set connector->link status inside set_link_status function
(Jani Nikula)
v3:
* Set link status property to BAd unconditionally (Jani Nikula)
* Dont use two separate variables link_train_failed and link_status
to indicate same thing (Jani Nikula)
v2:
* Squashed a few patches (Jani Nikula)

Now that source rates are static and sink rates are updated whenever
DPCD is updated, we can do and cache the intersection of them whenever
sink rates are updated. This reduces code complexity, as we don't have
to keep calling the functions to intersect. We also get rid of several
common rates arrays on stack.
Limiting the common rates by a max link rate can be done by picking the
first N elements of the cached common rates.

Looking at DPCD DP_MAX_LINK_RATE may be completely bogus for eDP 1.4
which is allowed to use link rate select method and have 0 in max link
rate. With this change, it makes sense to store the max rate as the
actual rate rather than as a bw code.

There is some conflation related to sink rates, making this change more
complicated than it would otherwise have to be. There are three changes
here that are rather difficult to split up:
1) Use the intel_dp->sink_rates array for all DP, not just eDP 1.4. We
initialize it from DPCD on eDP 1.4 like before, but generate it based
on DP_MAX_LINK_RATE on others. This reduces code complexity when we
need to use the sink rates; they are all always in the sink_rates
array.
2) Update the sink rate array whenever we read DPCD, and use the
information from there. This increases code readability when we need
the sink rates.
3) Disentangle fallback rate limiting from sink rates. In the code, the
max rate is a dynamic property of the *link*, not of the *sink*. Do
the limiting after intersecting the source and sink rates, which are
static properties of the devices.
This paves the way for follow-up refactoring that I've refrained from
doing here to keep this change as simple as it possibly can.

drm_helper_probe_single_connector_modes, v4.
mode_valid() called from drm_helper_probe_single_connector_modes()
may need to look at connector->state because what a valid mode is may
depend on connector properties being set. For example some HDMI modes
might be rejected when a connector property forces the connector
into DVI mode.
Some implementations of detect() already lock all state,
so we have to pass an acquire_ctx to them to prevent a deadlock.
This means changing the function signature of detect() slightly,
and passing the acquire_ctx for locking multiple crtc's.
For the callbacks, it will always be non-zero. To allow callers
not to worry about this, drm_helper_probe_detect_ctx is added
which might handle -EDEADLK for you.
Changes since v1:
- Always set ctx parameter.
Changes since v2:
- Always take connection_mutex when probing.
Changes since v3:
- Remove the ctx from intel_dp_long_pulse, and add
WARN_ON(!connection_mutex) (danvet)
- Update docs to clarify the locking situation. (danvet)

Geminilake platform sports a native HDMI 2.0 controller, and is
capable of driving pixel-clocks upto 594Mhz. HDMI 2.0 spec
mendates scrambling for these higher clocks, for reduced RF footprint.
This patch checks if the monitor supports scrambling, and if required,
enables it during the modeset.
V2: Addressed review comments from Ville:
- Do not track scrambling status in DRM layer, track somewhere in
driver like in intel_crtc_state.
- Don't talk to monitor at such a low layer, set monitor scrambling
in intel_enable_ddi() before enabling the port.
V3: Addressed review comments from Jani
- In comments, function names, use "sink" instead of "monitor",
so that the implementation could be close to the language of
HDMI spec.
V4: Addressed review comment from Maarten
- scrambling -> hdmi_scrambling
- high_tmds_clock_ratio -> hdmi_high_tmds_clock_ratio
V5: Addressed review comments from Ville and Ander
- Do not modifiy the crtc_state after compute_config. Move all
scrambling and tmds_clock_ratio calcutations to compute_config.
- While setting scrambling for source/sink, do not check the
conditions again, just go by the crtc_state flags. This will
simplyfy the condition checks.
V6: Addressed review comments from Ville
- Do not add IS_GLK check in disable/enable function, instead add it
in compute_config, while setting state flags.
- Remove unnecessary paranthesis.
- Simplyfy handle_sink_scrambling function as suggested.
- Add readout code for scrambling status in get_ddi_config and add a
check for the same in pipe_config_compare.
V7: Addressed review comments from Ander/Ville
- No separate function for source scrambling, make it inline
- Align the last line of the macro TRANS_DDI_HDMI_SCRAMBLING_MASK
- Do not add platform check while setting source scrambling
- Use pipe_config instead of crtc->config to set sink scrambling
- To readout scrambling status, Compare with SCRAMBLING_MASK
not any of its bits
- Remove platform check in intel_pipe_config_compare while checking
scrambling status
V8: Fixed mege conflict, Addressed review comments from Ander
- Remove the desciption/comment about scrambling fom the caller, move
it to the function
- Move the IS_GLK check into scrambling function
- Fix alignment
V9: Fixed review comments from Ville, Ander
- Pass the scrambling state variables as bool input to the sink_scrambling
function and let the disable call be unconditional.
- Fix alignments in function calls and debug messages.
- Add kernel doc for function intel_hdmi_handle_sink_scrambling

All it does is pick the encoder and call intel_get_shared_dpll(). We
can just do this in the caller. One less indirection level during code
reading.
As another plus, now the two callers of intel_get_shared_dpll() are
{ironlake,haswell}_crtc_compute_clock().

All the pre-SKL sprite planes compute the x/y/tile offsets in a
similar way. There are a couple of minor differences but the primary
planes have those as well. Thus i9xx_check_plane_surface()

On SKL the planes are uniform so the "sprites" can use the
primary plane code perfectly fine. The only difference we
have is the color key handling, but since we never enable that
for the primary plane the same code works just fine.

Backmerge drm-next to get at all the good stuff in drm-misc. We need
that because:
- drm_connector_list_iter conversion for i915 needs the core patches.
- Maarten's patches to use the new atomic state iterators also need
the core patches.
- We need the new link status property to complete the DP retraining
work, merging through 2 branches wasn't a good idea and we had to
partially backtrack.
- Chris needs reservation_object_trylock and we want to roll out
kref_read everywhere.

git://anongit.freedesktop.org/git/drm-misc into drm-next
First slice of drm-misc-next for 4.12:
Core/subsystem-wide:
- link status core patch from Manasi, for signalling link train fail
to userspace. I also had the i915 patch in here, but that had a
small buglet in our CI, so reverted.
- more debugfs_remove removal from Noralf, almost there now (Noralf
said he'll try to follow up with the stragglers).
- drm todo moved into kerneldoc, for better visibility (see
Documentation/gpu/todo.rst), lots of starter tasks in there.
- devm_ of helpers + use it in sti (from Ben Gaignard, acked by Rob
Herring)
- extended framebuffer fbdev support (for fbdev flipping), and vblank
wait ioctl fbdev support (Maxime Ripard)
- misc small things all over, as usual
- add vblank callbacks to drm_crtc_funcs, plus make lots of good use
of this to simplify drivers (Shawn Guo)
- new atomic iterator macros to unconfuse old vs. new state
Small drivers:
- vc4 improvements from Eric
- vc4 kerneldocs (Eric)!
- tons of improvements for dw-mipi-dsi in rockchip from John Keeping
and Chris Zhong.
- MAINTAINERS entries for drivers managed in drm-misc. It's not yet
official, still an experiment, but definitely not complete fail and
better to avoid confusion. We kinda screwed that up with drm-misc a
bit when we started committers last year.
- qxl atomic conversion (Gabriel Krisman)
- bunch of virtual driver polish (qxl, virgl, ...)
- misc tiny patches all over
This is the first time we've done the same merge-window blackout for
drm-misc as we've done for drm-intel for ages, hence why we have a
_lot_ of stuff queued already. But it's still only half of drm-intel
(room to grow!), and the drivers in drm-misc experiment seems to work
at least insofar as that you also get lots of driver updates here
alredy.

If link training at a link rate optimal for a particular
mode fails during modeset's atomic commit phase, then we
let the modeset complete and then retry. We save the link rate
value at which link training failed, update the link status property
to "BAD" and use a lower link rate to prune the modes. It will redo
the modeset on the current mode at lower link rate or if the current
mode gets pruned due to lower link constraints then, it will send a
hotplug uevent for userspace to handle it.
This is also required to pass DP CTS tests 4.3.1.3, 4.3.1.4,
4.3.1.6.

* Add fallback support for non DDI platforms too
* Set connector->link status inside set_link_status function

v3:
* Set link status property to BAd unconditionally (Jani Nikula)
* Dont use two separate variables link_train_failed and link_status
to indicate same thing (Jani Nikula)
v2:
* Squashed a few patches (Jani Nikula)

drm_debugfs_cleanup() now removes all minor->debugfs_list entries
automatically, so no need to do this explicitly. Additionally it
uses debugfs_remove_recursive() to clean up the debugfs files,
so no need for adding fake drm_info_node entries.

Pull drm updates from Dave Airlie:
"This is the main drm pull request for v4.11.
Nothing too major, the tinydrm and mmu-less support should make
writing smaller drivers easier for some of the simpler platforms, and
there are a bunch of documentation updates.
Intel grew displayport MST audio support which is hopefully useful to
people, and FBC is on by default for GEN9+ (so people know where to
look for regressions). AMDGPU has a lot of fixes that would like new
firmware files installed for some GPUs.
Other than that it's pretty scattered all over.
I may have a follow up pull request as I know BenH has a bunch of AST
rework and fixes and I'd like to get those in once they've been tested
by AST, and I've got at least one pull request I'm just trying to get
the author to fix up.

During system resume time initialization the HPD level on LSPCON ports
can stay low for an extended amount of time, leading to failed AUX
transfers and LSPCON initialization. Fix this by waiting for HPD to get
asserted.

With atomic plane states we are able to track an allocation right from
preparation, during use and through to the final free after being
swapped out for a new plane. We can couple the VMA we pin for the
framebuffer (and its rotation) to this lifetime and avoid all the clumsy
lookups in between.

v3: Add a description for the vma destruction in

Fences are required to support being released from under an atomic context.
The drm_atomic_state struct may take a mutex when being released and so
we cannot drop a reference to the drm_atomic_state from the fence release
path directly, and so we need to defer that unreference to a worker.

Remove crtc->wm.cxsr_allowed and just rely on crtc_state->disable_cxsr
instead. This was used only by vlv/chv to indicate whether to enable
cxsr in the wm computation. That doesn't really work anymore, and as far
as the optimal watermarks go we'll just consider the number of planes
and the current pipe, and for the intermediate watermarks we'll also
start to consider disable_cxsr which is set appropriately when planes
are being enabled/disabled.
We'll also flip over the crtc_state->wm.need_postvbl_update setup so
that it's the wm code that will set it. Previously the generic code set
it up, and then the wm code cleared it again if it thought it's not
needed after all.

Since the watermark registers arent double buffered on VLV/CHV, we'll
need to play around with intermediate watermarks same was as we do on
ILK-BDW.
The watermark registers on VLV/CHV contain inverted values, so to find
the intermediate watermark value we just take the minimum of the
active and optimal values. This also means that, unlike ILK-BDW,
there's no chance that we'd fail to find a working intermediate
watermarks. As long as both the active and optimal watermarks are valid
the intermediate watermarks will come out valid as well.

Check whether anything relevant has actually change when we compute new
watermarks for each plane in the state. If the watermarks for no
primary/sprite planes changed we don't have to recompute the FIFO split
or reprogram the DSBARB registers. And even the cursor watermarks didn't
change we can skip the merge+invert step between all the planes on
the pipe as well.

Start computing the vlv/chv watermarks the atomic way, from the
.compute_pipe_wm() hook. We'll recompute the actual watermarks
for only planes that are part of the state, the other planes will
keep their watermark from the last time it was computed.
And the actual watermark programming will happen from the
.initial_watermarks() hook. For now we'll just compute the
optimal watermarks, and we'll hook up the intermediate
watermarks properly later.
The DSPARB registers responsible for the FIFO paritioning are
double buffered, so they will be programming from
intel_begin_crtc_commit().

Let's compute the watermarks first and the FIFO size second. This way we
can make sure the FIFO split is the most accommodating to the watermarks.
Previously we could have potentially computed a FIFO split that couldn't
accommodate the PM2 watermarks simply due to a bad split even if the
total FIFO size would have been sufficient.
It'll also allow us to avoid recomputing the wms for all planes whenever
the FIFO split would change. Thus we don't have to add any extra planes
to the state when the FIFO needs to be repartitioned.
To help with this we'll keep around copies of the non-inverted
watermarks in the crtc state. For now that doesn't help too much, but
once we start to do the watermark computation only for the planes
that change we'll need the non-inverted values around for the other
planes.
