Whenever a connector on an MST network is attached, detached, or
undergoes a modeset, the DSC configs for each stream on that
topology will be recalculated. This can change their required
bandwidth, requiring a full reprogramming, as though a modeset
was performed, even if that stream did not change timing.
Therefore, whenever a crtc has drm_atomic_crtc_needs_modeset,
for each crtc that shares a MST topology with that stream and
supports DSC, add that crtc (and all affected connectors and
planes) to the atomic state and set mode_changed on its state

multiple displays per link.
[How]
We can create an array per link to cache the displays, but it
complicates the design. Instead we can use the module to cache the
displays.
Now we will always add all the displays to the module, but we use the
adjustment flag to disable hdcp on all of them before they are added.
When we want to enable hdcp we just query the display(cache), remove
it then add it back with different adjustments. Its the similar for

[Why]
HDCP 2.2 uses type0 and type1 content type. This is passed to the receiver
to stream the proper content.
For example, in a MST case if the main
device is HDCP2.2 capable but the secondary device is only 1.4 capabale
we can use Type0
Type0 content: use HDCP 1.4 or HDCP2.2 type0
Type1 content: Only use HDCP 2.2 type1
[How]
We use the "hdcp content type" property in drm. We use the
disable_type1 flag in hdcp module to select the type based on the
properties.
For updating the property we use the same logic as 1.4, but now we
consider content_type as well and update the property if the
requirements are met

[Why]
On DCN hardware, the crtc_high_irq handler makes vupdate_high_irq
handler redundant.
All the vupdate handler does is handle vblank events, and update vrr
for DCE hw (excluding VEGA, more on that later). As far as usermode is
concerned. vstartup happens close enough to vupdate on DCN that it can
be considered the "same". Handling vblank and updating vrr at vstartup
effectively replaces vupdate on DCN.
Vega is a bit special. Like DCN, the VRR registers on Vega are
double-buffered, and swapped at vupdate. But Unlike DCN, it lacks a
vstartup interrupt. This means we can't quite remove the vupdate handler
for it, since delayed user events due to vrr are sent off there.
[How]
Remove registration of vupdate interrupt handler for DCN. Disable
vupdate interrupt if asic family DCN, enable otherwise.

[Why]
For DCN hardware, the crtc_high_irq handler is assigned to the vstartup
interrupt. This is different from DCE, which has it assigned to vblank
start.
We'd like to send vblank and user events at vstartup because:
* It happens close enough to vupdate - the point of no return for HW.
* It is programmed as lines relative to vblank end - i.e. it is not in
the variable portion when VRR is enabled. We should signal user
events here.
* The pflip interrupt responsible for sending user events today only
fires if the DCH HUBP component is not clock gated. In situations
where planes are disabled - but the CRTC is enabled - user events won't
be sent out, leading to flip done timeouts.
Consequently, this makes vupdate on DCN hardware redundant. It will be
removed in the next change.
[How]
Add a DCN-specific crtc_high_irq handler, and hook it to the VStartup
signal. Inside the DCN handler, we send off user events if the pflip
handler hasn't already done so.

[Why]
It is confusing to sinks if we send VSC SDP only on some format. Today we
signal colorimetry format using MSA while in formats like sRGB.
But when we switch to BT2020 we set the bit to ignore MSA colorimetry and
instead use the colorimetry information in the VSC SDP.
But if sink supports signaling of colorimetry via VSC SDP we should always
set the MSA MISC1 bit 6, instead of doing so selectively.
[How]

[Why]
We need DMCUB on Renoir to support DMCU and PHY initialization.
The DMUB service provides a mechanism to load the DMCUB.
[How]
Include the DMUB service in amdgpu_dm.
Frontdoor loading of the DMCUB firmware needs to happen via PSP. To
pass the firmware to PSP we need to hand it off to the firmware list
in the base driver during software initialization.
Most of the DMUB service can technically be initialized at this point
in time, but we don't want to be allocating framebuffer memory for
hardware that doesn't support the DMCUB and in order to check that we
need to be able to read registers - something DM helpers aren't setup
to do in software initialization.
So everything but the service creation itself will get deferred to
hardware initialization.

Finally! For a very long time, our MST helpers have had one very
annoying issue: They don't know how to reprobe the topology state when
coming out of suspend. This means that if a user has a machine connected
to an MST topology and decides to suspend their machine, we lose all
topology changes that happened during that period. That can be a big
problem if the machine was connected to a different topology on the same
port before resuming, as we won't bother reprobing any of the ports and
likely cause the user's monitors not to come back up as expected.
So, we start fixing this by teaching our MST helpers how to reprobe the
link addresses of each connected topology when resuming. As it turns
out, the behavior that we want here is identical to the behavior we want
when initially probing a newly connected MST topology, with a couple of
important differences:
- We need to be more careful about handling the potential races between
events from the MST hub that could change the topology state as we're
performing the link address reprobe
- We need to be more careful about handling unlikely state changes on
ports - such as an input port turning into an output port, something
that would be far more likely to happen in situations like the MST hub
we're connected to being changed while we're suspend
Both of which have been solved by previous commits. That leaves one
requirement:
- We need to prune any MST ports in our in-memory topology state that
were present when suspending, but have not appeared in the post-resume
link address response from their parent branch device
Which we can now handle in this commit by modifying
drm_dp_send_link_address(). We then introduce suspend/resume reprobing
by introducing drm_dp_mst_topology_mgr_invalidate_mstb(), which we call
in drm_dp_mst_topology_mgr_suspend() to traverse the in-memory topology
state to indicate that each mstb needs it's link address resent and PBN
resources reprobed.
On resume, we start back up &mgr->work and have it reprobe the topology
in the same way we would on a hotplug, removing any leftover ports that
no longer appear in the topology state.
Changes since v4:
* Split indenting changes in drm_dp_mst_topology_mgr_resume() into a
separate patch
* Only fire hotplugs when something has actually changed after a link
address probe
* Don't try to change port->connector at all on ports, just throw out
ports that need their connectors removed to make things easier.

This is a complicated one. Essentially, there's currently a problem in the MST
core that hasn't really caused any issues that we're aware of (emphasis on "that
we're aware of"): locking.
When we go through and probe the link addresses and path resources in a
topology, we hold no locks when updating ports with said information. The
members I'm referring to in particular are:
- ldps
- ddps
- mcs
- pdt
- dpcd_rev
- num_sdp_streams
- num_sdp_stream_sinks
- available_pbn
- input
- connector
Now that we're handling UP requests asynchronously and will be using some of
the struct members mentioned above in atomic modesetting in the future for
features such as PBN validation, this is going to become a lot more important.
As well, the next few commits that prepare us for and introduce suspend/resume
reprobing will also need clear locking in order to prevent from additional
racing hilarities that we never could have hit in the past.
So, let's solve this issue by using &mgr->base.lock, the modesetting
lock which currently only protects &mgr->base.state. This works
perfectly because it allows us to avoid blocking connection_mutex
unnecessarily, and we can grab this in connector detection paths since
it's a ww mutex. We start by having drm_dp_mst_handle_up_req() hold this
when updating ports. For drm_dp_mst_handle_link_address_port() things
are a bit more complicated. As I've learned the hard way, we can grab
&mgr->lock.base for everything except for port->connector. See, our
normal driver probing paths end up generating this rather obvious
lockdep chain:
&drm->mode_config.mutex
-> crtc_ww_class_mutex/crtc_ww_class_acquire
-> &connector->mutex
However, sysfs grabs &drm->mode_config.mutex in order to protect itself
from connector state changing under it. Because this entails grabbing
kn->count, e.g. the lock that the kernel provides for protecting sysfs
contexts, we end up grabbing kn->count followed by
&drm->mode_config.mutex. This ends up creating an extremely rude chain:
&kn->count
-> &drm->mode_config.mutex
-> crtc_ww_class_mutex/crtc_ww_class_acquire
-> &connector->mutex
I mean, look at that thing! It's just evil!!! This gross thing ends up
making any calls to drm_connector_register()/drm_connector_unregister()
impossible when holding any kind of modesetting lock. This is annoying
because ideally, we always want to ensure that
drm_dp_mst_port->connector never changes when doing an atomic commit or
check that would affect the atomic topology state so that it can
reliably and easily be used from future DRM DP MST helpers to assist
with tasks such as scanning through the current VCPI allocations and
adding connectors which need to have their allocations updated in
response to a bandwidth change or the like.
Being able to hold &mgr->base.lock throughout the entire link probe
process would have been _great_, since we could prevent userspace from
ever seeing any states in-between individual port changes and as a
result likely end up with a much faster probe and more consistent
results from said probes. But without some rework of how we handle
connector probing in sysfs it's not at all currently possible. In the
future, maybe we can try using the sysfs locks to protect updates to
connector probing state and fix this mess.
So for now, to protect everything other than port->connector under
&mgr->base.lock and ensure that we still have the guarantee that atomic
check/commit contexts will never see port->connector change we use a
silly trick. See: port->connector only needs to change in order to
ensure that input ports (see the MST spec) never have a ghost connector
associated with them. But, there's nothing stopping us from simply
throwing the entire port out and creating a new one in order to maintain
that requirement while still keeping port->connector consistent across
the lifetime of the port in atomic check/commit contexts. For all
intended purposes this works fine, as we validate ports in any contexts
we care about before using them and as such will end up reporting the
connector as disconnected until it's port's destruction finalizes. So,
we just do that in cases where we detect port->input has transitioned
from true->false. We don't need to worry about the other direction,
since a port without a connector isn't visible to userspace and as such
doesn't need to be protected by &mgr->base.lock until we finish
registering a connector for it.
For updating members of drm_dp_mst_port other than port->connector, we
simply grab &mgr->base.lock in drm_dp_mst_link_probe_work() for already
registered ports, update said members and drop the lock before
potentially registering a connector and probing the link address of it's
children.
Finally, we modify drm_dp_mst_detect_port() to take a modesetting lock
acquisition context in order to acquire &mgr->base.lock under
&connection_mutex and convert all it's users over to using the
.detect_ctx probe hooks.
With that, we finally have well defined locking.
Changes since v4:
* Get rid of port->mutex, stop using connection_mutex and just use our own
modesetting lock - mgr->base.lock. Also, add a probe_lock that comes
before this patch.
* Just throw out ports that get changed from an output to an input, and
replace them with new ports. This lets us ensure that modesetting
contexts never see port->connector go from having a connector to being
NULL.
* Write an extremely detailed explanation of what problems this is
trying to fix, since there's a _lot_ of context here and I honestly
forgot some of it myself a couple times.
* Don't grab mgr->lock when reading port->mstb in
drm_dp_mst_handle_link_address_port(). It's not needed.

[Why]
HDMI 2.0 requires scrambling under specific conditions. We refer to
stream property LTE_340MCSC_SCRAMBLE to determine whether en/dis
scrambling.
While creating stream for sink, we setup LTE_340MCSC_SCRAMBLE by
referring to edid_caps. However, dm_helpers_parse_edid_caps()
doesn't construct HDMI Forum block data for edid_caps.
Moreover, fill_stream_properties_from_drm_display_mode() aslo
unconsciously clear the LTE_340MCSC_SCRAMBLE flag.
[How]
Drm already provides drm_display_info to refer HDMI Forum vsdb info.
Set stream LTE_340MCSC_SCRAMBLE by drm_display_info and remove
memset in fill_stream_properties_from_drm_display_mode()

[Why]
To compare the crc of the framebuffer data at input of
display pipeline with the crc of the otg, we need to
disable pixel formatter's dynamic expansion feature during
crc capture and keep it enable in the normal operation.
[HOW]
Expose a new interface in DM and dc for pixel formatter
(fmt dynamic bitdepth expansion control). Interface control
the FMT_DYNAMIC_EXP_EN bit, during crc capture keep

[Why]
A lot of the time, the backlight characteristic curve maps min backlight
to a non-zero value.
But there are cases where we want the curve to intersect at 0.
In this scenario even if OS never asks to set 0% backlight, the ABM
reduction can result in backlight being lowered close to 0.
This particularly can cause problems in some LED drivers, and in
general just looks like backlight is completely off.
[How]
Add default cap to disallow backlight from dropping below 1%
even after ABM reduction is applied.

Laptops with AMD APU doesn't restore display backlight brightness after
system resume.
This issue started when DC was introduced.
Let's use BL_CORE_SUSPENDRESUME so the backlight core calls
update_status callback after system resume to restore the backlight
level.
Tested on Dell Inspiron 3180 (Stoney Ridge) and Dell Latitude 5495
(Raven Ridge).

[Why]
We need to ensure that we're holding the lock on the CRTC when setting
the CRC source since we're modifying the CRTC state directly.
We also need to wait for any outstanding non-blocking commits to finish
so they aren't reading state that's potentially being modified -
non-blocking commits don't hold the CRTC lock while doing commit tail
work.
[How]
Lock the CRTC using its mutex. While holding the lock check if there's
any commit active on the CRTC - if there is, it's non-blocking and
we should wait until it's finished by waiting for hw_done to be
signaled since that's the last point where we touch CRTC state.

[Why]
Calling amdgpu_dm_crtc_set_crc_source in amdgpu_dm directly has the
consequence of adding additional vblank references or starting DPRX
CRC capture more than once without calling stop first.
Vblank references for CRC capture should be managed entirely by opening
and closing the CRC file from userspace.
Stream state also shouldn't be required on the CRC so we can close the
file after the CRTC has been disabled.
[How]
Do DC programming required for configuring CRC capture separately from
setting the source. Whenever we re-enable or reset a CRC this
programming should be reapplied.
CRC vblank reference handling in amdgpu_dm can be entirely dropped after
this.
Stream state also no longer needs to be required since we can just defer
the programming to when the stream is actually enabled.

[Why]
Underflow can occur in the case where we change buffer pitch, DCC state,
rotation or mirroring for a plane while also performing an immediate
flip. It can also generate a p-state warning stack trace on DCN1 which
is typically observed during the cursor handler pipe locking because of
how frequent cursor updates can occur.
[How]
Store the update type on each CRTC - every plane will have access to
the CRTC state if it's flipping. If the update type is not
UPDATE_TYPE_FAST then the immediate flip should be disallowed.
No changes to the target vblank sequencing need to be done, we just
need to ensure that the surface registers do a double buffered update.

Underflow (visible or non-visible) can occur if we don't validate this

via the cursor handler when locking.

[Why]
DRM private objects have no hw_done/flip_done fencing mechanism on their
own and cannot be used to sequence commits accordingly.
When issuing commits that don't touch the same set of hardware resources
like page-flips on different CRTCs we can run into the issue below
because of this:
1. Client requests non-blocking Commit #1, has a new dc_state #1,
state is swapped, commit tail is deferred to work queue
2. Client requests non-blocking Commit #2, has a new dc_state #2,
state is swapped, commit tail is deferred to work queue
3. Commit #2 work starts, commit tail finishes,
atomic state is cleared, dc_state #1 is freed
4. Commit #1 work starts,
commit tail encounters null pointer deref on dc_state #1
In order to change the DC state as in the private object we need to
ensure that we wait for all outstanding commits to finish and that
any other pending commits must wait for the current one to finish as
well.
We do this for MEDIUM and FULL updates. But not for FAST updates, nor
would we want to since it would cause stuttering from the delays.
FAST updates that go through dm_determine_update_type_for_commit always
create a new dc_state and lock the DRM private object if there are
any changed planes.
We need the old state to validate, but we don't actually need the new
state here.
[How]
If the commit isn't a full update then the use after free can be
resolved by simply discarding the new state entirely and retaining
the existing one instead.
With this change the sequence above can be reexamined. Commit #2 will
still free Commit #1's reference, but before this happens we actually
added an additional reference as part of Commit #2.
If an update comes in during this that needs to change the dc_state
it will need to wait on Commit #1 and Commit #2 to finish. Then it'll
swap the state, finish the work in commit tail and drop the last
reference on Commit #2's dc_state.

By passing through the dm_determine_update_type_for_commit for atomic

performance penalty by locking access to the global private object
and holding that access until the end of the programming sequence.
This is also allocating a new large dc_state on every access in addition
to retaining all the references on each stream and plane until the end
of the programming sequence.

[Why]
We previously allowed framebuffer swaps as async updates for cursor
planes but had to disable them due to a bug in DRM with async update
handling and incorrect ref counting. The check to block framebuffer
swaps has been added to DRM for a while now, so this check is redundant.
The real fix that allows this to properly in DRM has also finally been
merged and is getting backported into stable branches, so dropping
this now seems to be the right time to do so.
[How]
Drop the redundant check for old_fb != new_fb.
With the proper fix in DRM, this should also fix some cursor stuttering
issues with xf86-video-amdgpu since it double buffers the cursor.
IGT tests that swap framebuffers (-varying-size for example) should
also pass again.

[Why]
The drm_audio_component can be used to give pin ELD notifications
directly to the sound driver. This fixes audio endpoints disappearing
due to missing unsolicited notifications.
[How]
Send the notification via the audio component whenever we enable or
disable audio state on a stream. This matches what i915 does with
their drm_audio_component and what Takashi Iwai's proposed hack for
radeon/amdpgu did.
This is a bit delayed in when the notification actually occurs, however.
We wait until after all the programming is complete rather than sending
the notification mid sequence.
Particular care is needed for the get ELD callback since it can happen
outside the locking and fencing DRM does for atomic commits.

However this is only true for virtual DP-to-DP peer device.
In general there are three types of virtual DP peer devices.
1. Sink peer device with virtual DPCD.
2. Virtual DP-to-DP Peer device with virtual DPCD.
3. Virtual DP-to-HDMI Protocol Converter Peer Device with
Virtual DPCD.
So we should break the assumption and handle all three types.

DP-to-DP peer device will have virtual DPCD cap upstream.
Sink peer device will have virtual DPCD on the logical port.
Dp to HDMI protocol converter peer device will have virtual DPCD
on its converter port.

[Why]
The module parameter to specify the default ABM level is now defined,
so hook it up in DM.
[How]
On connector reset specify the default level. DC will program this as
part of the modeset since it gets passed onto the stream in
dm_update_crtc_state.
It's only set for eDP connectors, but it doesn't matter if this is
specified for connectors or hardware that doesn't support ABM.
It's DC's responsibility to check that ABM can be set or adjusted, and
DC does check that the DMCU firmware is running and if there's backlight
control available.

[Why]
Whenever the a modeset is allowed (but not neccessarily required) we
currently recreate all the planes in the state. Most IGT tests and
legacy IOCTLs create atomic commits with this flag set, so the pipes
are often unnecessarily reprogrammed.
Poor performance and stuttering can occur when many of these commits
are frequently issued.
This flag was needed when the appropriate conditions for checking
whether the planes needed a reset were not in place, but
should_reset_plane should cover everything needed now.
[How]
Drop the check for state->allow_modeset in should_reset_plane.
All planes on a CRTC should reset in the following conditions:
- The CRTC needs a modeset
- The CRTC degamma changes
- Planes are added or removed to the CRTC
These conditions are all covered in should_reset_plane.
We still can't drop the format change check in should_reset_plane since
fill_dc_plane_info_and_addr isn't called when validating the state, so
we can't tell if a FULL update is needed or not.

[Why]
The old logic for checking which output depth to use relied on using
the current connector state rather than the new proposed state. This
was a problem when performing atomic commits since we weren't verifying
it against the incoming max_requested_bpc.
But switching this to only use the new state and not the current state
breaks filtering modes - it'll always assume that the maximum bpc
supported by the display is in use, which will cause certain modes
like 1440p@144Hz to be filtered even when using 8bpc.
[How]
Still use the connector->state if we aren't passed an explicit state.
This will respect the max_bpc the user currently has when filtering
modes.
Also remember to reset the default max_requested_bpc to 8 whenever
connector reset is called to retain old behavior when using the new
property.

occur when attaching the bpc property since it tries to modify the
connector state.
We need an initial connector state on the connector to avoid the crash.
[How]
Use our reset helper to allocate an initial state and reset the values
to their defaults. We were already doing this before, just not for
MST connectors.

[Why]
When switching from vt to desktop with EDID emulation we can receive
an atomic commit such that we have a crtc where mode_changed = true.
During the dm_update_crtc_state disable pass we remove the stream from
the context and free it on the dm_new_crtc_state.
During the enable pass we compare the new provisional stream to the
dm_old_crtc_state->stream and determine that the stream is unchanged
and no scaling has been changed.
Following this, new_crtc_state->mode_changed is then set to false.
The connectors haven't changed and the CRTC active state hasn't changed
so drm_atomic_crtc_needs_modeset returns false, so we jump to
skip_modeset and we hit:
BUG_ON(dm_new_crtc_state->stream == NULL);
...since the old stream is gone from the context and the new stream is
also still NULL.
[How]
Ensure that we still a stream to reuse before checking if we can reuse
the old stream without a full modeset.

[Why]
For userspace to send static HDR metadata to the display we need to
attach the property on the connector and send it to DC.
[How]
The property is attached to HDMI and DP connectors. Since the metadata
isn't actually available when creating the connector this isn't a
property we can dynamically support based on the extension block
being available or not.
When the HDR metadata is changed a modeset will be forced for now.
We need to switch from 8bpc to 10bpc in most cases anyway, and we want
to fully exit HDR mode when userspace gives us a NULL metadata, so this
isn't completely unnecessary.
The requirement can later be reduced to just entering and exiting HDR
or switching max bpc.

[Why]
There are monitors which can have more than one preferred mode
set. There are chances in these monitors that if common modes are
added in function amdgpu_dm_connector_add_common_modes(), these
common modes can be calculated with different preferred mode than
the one used in function decide_crtc_timing_for_drm_display_mode().
The preferred mode can be different because after common modes
are added, the mode list is sorted and this changes the order of
preferred modes in the list. The first mode in the list with
preferred flag set is selected as preferred mode. Due to this the
preferred mode selected varies.
If same preferred mode is not selected in common mode calculation
and crtc timing, then during mode set instead of setting preferred
timing, common mode timing will be applied which can cause "out of
range" message in the monitor with monitor blanking out.
[How]
Sort the modes before adding common modes. The same sorting function
is called during common mode addition and deciding crtc timing.

The current state on the connector is queried when getting the max bpc

currently take effect on the commit *after* it changes.
The new state should be passed in instead.
[How]
Pass down the dm_state as drm state to where we do color depth lookup.
The passed in state can still be NULL when called from
amdgpu_dm_connector_mode_valid, so make sure that we have reasonable
defaults in place. That should probably be addressed at some point.
This change now (correctly) causes a modeset to occur when changing the

[Why]
When x or y is negative we set the x and y values to 0 and compensate
with a positive cursor hotspot in DM since DC expects positive cursor
values.
When x or y is less than or equal to the maximum cursor width or height
the cursor hotspot is clamped so the hotspot doesn't exceed the
cursor size:
if (x < 0) {
xorigin = min(-x, amdgpu_crtc->max_cursor_width - 1);
x = 0;
}
if (y < 0) {
yorigin = min(-y, amdgpu_crtc->max_cursor_height - 1);
y = 0;
}
This incorrectly forces the cursor to be at least 1 pixel on the screen
in either direction when x or y is sufficiently negative.

Just disable the cursor when it goes far enough off the screen in one
of these directions.

Pre-DCE12 needs special treatment for BTR / low framerate
compensation for more stable behaviour:
According to comments in the code and some testing on DCE-8
and DCE-11, DCE-11 and earlier only apply VTOTAL_MIN/MAX
programming with a lag of one frame, so the special BTR hw
programming for intermediate fixed duration frames must be
done inside the current frame at flip submission in atomic
commit tail, ie. one vblank earlier, and the fixed refresh
intermediate frame mode must be also terminated one vblank
earlier on pre-DCE12 display engines.
To achieve proper termination on < DCE-12 shift the point
when the switch-back from fixed vblank duration to variable
vblank duration happens from the start of VBLANK (vblank irq,
as done on DCE-12+) to back-porch or end of VBLANK (handled
by vupdate irq handler). We must leave the switch-back code
inside VBLANK irq for DCE12+, as before.
Doing this, we get much better behaviour of BTR for up-sweeps,
ie. going from short to long frame durations (~high to low fps)
and for constant framerate flips, as tested on DCE-8 and
DCE-11. Behaviour is still not quite as good as on DCN-1
though.
On down-sweeps, going from long to short frame durations
(low fps to high fps) < DCE-12 is a little bit improved,
although by far not as much as for up-sweeps and constant
fps.

moved around for support enabling CRTCs with no primary planes
active this was no longer being called in the case where there
wasn't a modeset.
This fixes failures in igt@kms_vrr@* with error
"Timed out: Waiting for vblank event".
[How]
Shift them back into the loop that always ran before interrupts were
enabled.
Pull out the logic that updated VRR state into the same loop since
there's no reason these need to be split.
In the case where we're going from VRR off, no planes to VRR on, some
active planes we'll still be covered for having the VRR vupdate
handler enabled - vblank will be re-enabled at this point, it will
see that VRR is active and set the vupdate interrupt on there.

Add a check to reject commits that have cursor planes enabled and
nothing else on CRTCs since we can't handle that. The new helper
does_crtc_have_active_cursor is used for this.
In atomic commit tail, we need to let DC know that there are zero
planes enabled when doing stream updates to let it disable and blank
pipes as appropriate.

[Why]
When disabling all the pipes for a CRTC the page-flip interrupt also
gets disabled on Raven. We can't re-enable the page-flip interrupt
unless we give DC at least one active DC plane.
We currently enable interrupts after the call to dc_commit_state since
there's currently no valid sequence that should disable all the planes
or re-enable planes for a CRTC without first going through
dc_commit_state.
If we were to allow for a CRTC to be enabled with no primary plane this
would not be the case - the call to dc_commit_updates_for_stream would
enable the planes when going from zero to at least one active plane,
but manage_dm_interrupts would have been called too early.
This results in a page-flip timeout on any subsequent commits since we
think the page-flip are now enabled when they're actually disabled.
We need to enable interrupts after the call to
dc_commit_updates_for_stream.
[How]
Split enabling interrupts into two passes. One pass before
dc_commit_updates_for_stream and one after it.
Shifting all the interrupts to be strictly below the call doesn't
currently work even though it should in theory. We end up queuing
off the vblank event to be handle by the flip handler before it's
actually enabled in some cases, particularly:
old_crtc_state->active = false -> new_crtc_state->active = true
The framebuffer states haven't changed and we can technically still
do a "pageflip" in this case and send back the event.

We only currently drop the vblank reference when the stream is

We also never get the extra reference correctly when re-enabling
interrupts, since grabbing the reference has the following condition:
if (!crtc_state->crc_enabled && enable)
drm_crtc_vblank_get(crtc);
This means that crc_enabled must be *false* in order to grab the extra
reference.
[How]
Always drop the ref whenever we're disabling interrupts.
Only disable CRC capture when the stream is being removed.
Always grab the ref by setting dm_new_crtc_state->crc_enabled = false

[Why]
The vblank and pageflip interrupts should only be enabled for a CRTC
that's enabled and has active planes.
The current logic takes care of this, but isn't setup to handle the case
where the active plane count goes to zero but the stream remains
enabled.
We currently block this case since we don't allow commits that enable a
CRTC with no active planes, but shouldn't be any reason we can't support
this from a hardware perspective and many userspace applications expect
to be able to do it (like IGT).
[How]
The count_crtc_active_planes function fills in the number of
"active_planes" on the dm_crtc_state. This should be the same as
DC's plane_count on the stream_status but easier to access since we
don't need to lock the private atomic state with the DC context.
Add the "interrupts_enabled" flag to the dm_crtc_state and set it based
on whether the stream exists and if there are active planes on the
stream.
Update the disable and enable logic to make use of this new flag.
There shouldn't be any functional change (yet) with this patch.

where the FB hasn't been previously been used.
This isn't quite a refactor, but functionally driver behavior should
be mostly the smae as before. The one exception is that we now check

Afterwards, amdgpu_dm calls dc_set_power_state() with S3 power state.
This invalidates dc->current_state by wiping it to 0, consequently
wiping dm_atomic_state->context.
During resume, the cached atomic state is restored. When getting the
private object however, the dm_atomic_state - containing the wiped
context - is duplicated into the atomic state. This causes DC validation
to fail during atomic check, as necessary function pointers in dc_state
are now NULL.

We want vblank counts and timestamps of flip completion as sent
in pageflip completion events to be consistent with the vblank
count and timestamp of the vblank of flip completion, like in non
VRR mode.
In VRR mode, drm_update_vblank_count() - and thereby vblank
count and timestamp updates - must be delayed until after the
end of front-porch of each vblank, as it is only safe to
calculate vblank timestamps outside of the front-porch, when
we actually know when the vblank will end or has ended.
The function drm_update_vblank_count() which updates timestamps
and counts gets called by drm_crtc_accurate_vblank_count() or by
drm_crtc_handle_vblank().
Therefore we must make sure that pageflip events for a completed
flip are only sent out after drm_crtc_accurate_vblank_count() or
drm_crtc_handle_vblank() is executed, after end of front-porch
for the vblank of flip completion.
Two cases:
a) Pageflip irq handler executes inside front-porch:
In this case we must defer sending pageflip events until
drm_crtc_handle_vblank() executes after end of front-porch,
and thereby calculates proper vblank count and timestamp.
Iow. the pflip irq handler must just arm a pageflip event
to be sent out by drm_crtc_handle_vblank() later on.
b) Pageflip irq handler executes after end of front-porch, e.g.,
after flip completion in back-porch or due to a massively
delayed handler invocation into the active scanout of the new
frame. In this case we can call drm_crtc_accurate_vblank_count()
to safely force calculation of a proper vblank count and
timestamp, and must send the pageflip completion event
ourselves from the pageflip irq handler.
This is the same behaviour as needed for standard fixed refresh
rate mode.
To decide from within pageflip handler if we are in case a) or b),
we check the current scanout position against the boundary of
front-porch. In non-VRR mode we just do what we did in the past.

We add a new vupdate irq, which triggers at the end of the vupdate

For throttling to work correctly, we always need a baseline vblank
count last_flip_vblank that increments at start of front-porch.
This is the case for drm_crtc_vblank_count() in non-VRR mode, where
the vblank irq fires at start of front-porch and triggers DRM core
vblank handling, but it is no longer the case in VRR mode, where
core vblank handling is done later, after end of front-porch.
Therefore drm_crtc_vblank_count() is no longer useful for this.
We also can't use drm_crtc_accurate_vblank_count(), as that would
screw up vblank timestamps in VRR mode when called in front-porch.
To solve this, use the cooked hardware vblank counter returned by
amdgpu_get_vblank_counter_kms() instead, as that one is cooked to
always increment at start of front-porch, independent of when
vblank related irq's fire.
This patch allows vblank irq handling to happen anywhere within
vblank of even after it, without a negative impact on flip
throttling, so followup patches can shift the vblank core
handling trigger point wherever they need it.

[Why]
Black screens or artifacting can occur when enabling FreeSync outside
of the supported range of the monitor. This can happen since the
supported range isn't always the min/max vrefresh range available for
the monitor.
[How]
There was previously a fix that prevented this from happening in the
low range but it didn't cover the upper range. Expand the condition
to include both.

We want DRM planes to be initialized in the following order:
- primary planes
- overlay planes
- cursor planes
to support existing userspace expectations for plane z-ordering. This
means that we also need to register CRTCs after all planes have been
initialized since overlay planes can be placed on any CRTC.
So the only reason why we have the mode_info->planes list is to
remember the primary planes for use later when we need to register
the CRTC.
Overlay planes have no purpose being in this list. DRM will cleanup
any planes that we've registered for us, so the only planes that need to
be explicitly cleaned up are the ones that have failed to register.
By dropping the explicit free on every plane in the mode_info->planes
list this patch also fixes a double-free in the case where we fail to
initialize only some of the planes.

[Why]
The plane_reset callback is subclassed but hasn't been updated since
the drm helper got updated to include resetting alpha related state
(state->alpha and state->pixel_blend_mode). The overlay planes
exposed by amdgpu_dm were therefore being rendered as invisible by
default ever since supported was exposed for alpha blending properties
on overlays.
This caused regressions in igt@kms_plane_multiple@atomic-tiling-none
and igt@kms_plane@plane-position-covered-pipe tests.
[How]
Reset the plane state values to their correct values as defined in
the drm helper.
This fixes the IGT test regression.

[Why]
Incorrect hardcoded assumptions are made regarding luma and chroma
alignment. The actual values set for the DRM framebuffer should be used
when programming the address.
[How]
Respect the given pitch for both luma and chroma planes - it's not like
we can force the alignment to anything else at this point anyway.
Use the FB offset for the chroma planes directly. DRM already
provides this to us so there's no need to calculate it manually.
While we don't actually use the chroma surface size parameters on Raven,
these should have technically been fb->width / 2 and fb->height / 2
since the chroma plane is half size of the luma plane for NV12.
Leave a TODO indicating that those should be set based on the actual
surface format instead since this is only correct for YUV420 formats.

[Why]
For new DC planes the correct plane address fields are filled based
on whether the plane had a graphics or video format.
However, when we perform stream and plane updates using DC we only ever
fill in the graphics format fields. This causing corruption and hangs
when using video surface formats like NV12 for planes.
[How]
Use the same logic everywhere we update dc_plane_address - always
fill in the correct fields based on the surface format type.
There are 3 places this is done:
- Atomic check, during DC plane creation
- Atomic commit, during plane prepare_fb
- Atomic commit tail, during amdgpu_dm_commit_planes
We use the fill_plane_tiling_attributes in all 3 locations and it
already needs the address to update DCC attributes, so the surface
address update logic can be moved into this helper.

[Why]
New DRM versions manage locking for private objects for us, so this
is no longer needed.
This also prevents a WARN_ON from occurring when the private object is
duplicated during the forced atomic commit that occurs from the HPD
handler.
The HPD handler calls drm_modeset_lock_all before the forced commit
and if the private object is duplicated then the
DEBUG_LOCKS_WARN_ON(ww_ctx->done_acquire) warning will be triggered
since we're trying to lock something when everything should have
already been locked.
[How]
Drop the lock and let DRM manage this.

[Why]
Tiling and DCC attributes can change when swapping framebuffers but
these will only ever get updated on full commits where
state->allow_modeset is true. But for the page-flip IOCTL
state->allow_modeset = false so these aren't updated and DCC changes
aren't being programmed.
[How]
Split out updating the tiling and DCC attributes into its own function
that's called when creating the plane for the first time but also
called when switching framebuffers before commit stream updates.
These functions also don't modify the plane state directly since the
plane state being used as reference is often the current one
being used by the hardware.
DC needs to be able to compare plane_state to the stream update
structures to determine if the hardware programming should happen. If
it's modified in place then nothing will be programmed and we can run
into concurrency issues.
