If we have framebuffers that are >= 4GiB in size we will overflow
the fb size check in intel_fill_fb_info().
Currently that is only possible with NV12 and CCS as offsets[1]
may be anything between 0 and 0xffffffff. offsets[0] is currently
required to be 0 so we can't hit the overflow with any single
plane format (thanks to max fb size of 8kx8k and max stride of
32 KiB).
In the future we may allow almost any framebuffer to exceed 4GiB
in size so we really should fix the overflow. Not that the overflow
is particularly dangerous. It's mostly just a sanity check against
insane userspace. The display engine can't write to memory anyway
so I suppose in the worst case we might anger the hw by attempting
scanout past the end of the ggtt, or we might scan out some data
that we're not supposed to see from other parts of the ggtt.
Note that triggering this overflow depends on the driver
aligning the fb height to the next tile boundary to push the
calculated size above 4GiB. With linear buffers the effective
tile height is one so that never happens, and the core already
has a check for 32bit overflow of offsets[]+pitches[]*height.

The optimisation inherent in commit 6a2c4232ec ("drm/i915: Make the
physical object coherent with GTT") relies on that once we allocated a
cursor we would have coherent, zero overhead access to the scanout plane
holding the cursor. That is we could then do the very frequent cursor
updates X enjoys with no indirection or kernel involvement. However,
that all hinges on the GGTT mmap of the cursor being pinned and not
require refaulting on each access -- handling such a page fault likely
requires the busy GGTT to be rearranged causing a stall. A very simple
fix is then to handle the physical cursor exactly like other cursors and
keep its vma pinned while active.

After
commit 2cd9a689e9 ("drm/i915: Refactor intel_display_set_init_power() logic")
it makes more sense to check the power domain/well refcounts after
enabling the power domains functionality. Before that it's guaranteed
that most power wells (in the INIT domain) will have a reference held,
so not an interesting state.
While at it also add the check after the init_hw/fini_hw, disable and
suspend/resume steps. Make the test optional on a Kconfig option since
it may add substantial overhead: on VLV/CHV the corresponding PUNIT reg
access for each power well may take up to 20ms.
v2:
- Add the state check to more spots. (Chris)
v3:
- During suspend check the state before deiniting display core.
Afterwards DC states are disabled (and so the dc_off power well is
enabled) even though we don't hold a reference on it.
- Do the test conditionally based on a new Kconfig option. (Chris)

We require that we keep the list of outstanding work short so that we do
not "leak" memory while pageflipping under stress. However that system
stress may delay kernel workers virtually indefinitely, which incurs the
pageflips stall and eventually hit a timeout waiting for the cleanup.
Try to combat CPU starvation of our short-lived cleanup workers by
switching to a high priority workqueue.

Similarly to the previous patch use a separate request/status HW flag
index defined right after the corresponding control registers instead of
depending for this on the power well IDs. Since the set of
control/status registers varies among the different power wells (on a
single platform), also add a new i915_power_well_registers struct that
we populate and assign to each DDI power well as needed.
Also clarify a bit the code comment describing the function and layout
of the control registers.
This also fixes a problem on ICL, where we incorrectly read the KVMR
control register in hsw_power_well_requesters() even for DDI and AUX
power wells.
v2:
- Clarify platform range tags in code comments. (Paulo)
- Fix line over 80 chars checkpatch warning.

RPS provides a feedback loop where we use the load during the previous
evaluation interval to decide whether to up or down clock the GPU
frequency. Our responsiveness is split into 3 regimes, a high and low
plateau with the intent to keep the gpu clocked high to cover occasional
stalls under high load, and low despite occasional glitches under steady
low load, and inbetween. However, we run into situations like kodi where
we want to stay at low power (video decoding is done efficiently
inside the fixed function HW and doesn't need high clocks even for high
bitrate streams), but just occasionally the pipeline is more complex
than a video decode and we need a smidgen of extra GPU power to present
on time. In the high power regime, we sample at sub frame intervals with
a bias to upclocking, and conversely at low power we sample over a few
frames worth to provide what we consider to be the right levels of
responsiveness respectively. At low power, we more or less expect to be
kicked out to high power at the start of a busy sequence by waitboosting.
Prior to commit e9af4ea2b9 ("drm/i915: Avoid waitboosting on the active
request") whenever we missed the frame or stalled, we would immediate go
full throttle and upclock the GPU to max. But in commit e9af4ea2b9, we
relaxed the waitboosting to only apply if the pipeline was deep to avoid
over-committing resources for a near miss. Sadly though, a near miss is
still a miss, and perceptible as jitter in the frame delivery.
To try and prevent the near miss before having to resort to boosting
after the fact, we use the pageflip queue as an indication that we are
in an "interactive" regime and so should sample the load more frequently
to provide power before the frame misses it vblank. This will make us
more favorable to providing a small power increase (one or two bins) as
required rather than going all the way to maximum and then having to
work back down again. (We still keep the waitboosting mechanism around
just in case a dramatic change in system load requires urgent uplocking,
faster than we can provide in a few evaluation intervals.)
v2: Reduce rps_set_interactive to a boolean parameter to avoid the
confusion of what if they wanted a new power mode after pinning to a
different mode (which to choose?)
v3: Only reprogram RPS while the GT is awake, it will be set when we
wake the GT, and while off warns about being used outside of rpm.
v4: Fix deferred application of interactive mode
v5: s/state/interactive/
v6: Group the mutex with its principle in a substruct

The warning is seen when mode_setcrtc() is called for pipeB
during bootup and before we get a mode_setcrtc() for pipeA,
while doing update_crtcs() in intel_atomic_commit_tail().
Now since, plane1A is still active after commit, update_crtcs()
is done for pipeA and eventually update_plane() for plane1A.
intel_plane_state->ctl for plane1A is not updated since set_modecrtc() is
called for pipeB. So intel_plane_state->ctl for plane 1A will be 0x0.
So doing an update_plane() for plane1A, will result in clearing
PLANE_CTL_ENABLE bit, and hence the warning.
To fix this warning, force all active planes to recompute their states
in probe.

On GLK NUC platforms the HDMI retiming buffer needs additional disabled
time to correctly sync to a faster incoming signal.
When measured on a scope the highspeed lines of the HDMI clock turn off
for ~400uS during a normal resolution change. The HDMI retimer on the
GLK NUC appears to require at least a full frame of quiet time before a
new faster clock can be correctly sync'd. Wait 100ms due to msleep
inaccuracies while waiting for a completed frame. Add a quirk to the
driver for GLK boards that use ITE66317 HDMI retimers.
V2: Add more devices to the quirk list
V3: Delay increased to 100ms, check to confirm crtc type is HDMI.
V4: crtc type check extended to include _DDI and whitespace fixes
v5: Fix white spaces, remove the macro for delay. Revert the crtc type
check introduced in v4.

We can simplify the encoder's get_power_domains() hook by calling it
only if the encoder is active. That way the hook can return its power
domains unconditionally without checking the active state by calling
encoder::get_hw_state(). This get_hw_state() query is in fact
redundant since it's already done by intel_modeset_readout_hw_state()
setting the encoder's crtc or leaving it NULL accordingly. Let's use
this fact to decide if the encoder is active.
While at it clarify the comment in intel_ddi_get_power_domains() about
primary vs. fake MST encoders and make sure we never do an incorrect
encoder->dig_port cast for fake MST encoders.

Avoid confusion with the functions to be added for the new ICL or gen 11
DSI implementation by renaming the current DSI functions. While at it,
permutate the words in the function names to make them all start with
"vlv_dsi" or "vlv_dsi_pll" etc.
Reduce the platform abstractions in the PLL file while at it, moving the
checks to vlv_dsi.c instead, where we typically already have the
necessary if ladders.
Leave the static functions as-is for now; they could be renamed later if
needed.
No functional changes.
v2: use "gen7" prefix.
v3: use "vlv" and "bxt" prefixes, reduce the abstractions.

So far we got an AUX power domain reference only for the duration of DP
AUX transfers. However, the following suggests that we also need these
for main link functionality:
- The specification doesn't state whether it's needed or not for main
link functionality, but suggests that these power wells need to be
enabled already during display core initialization (Sequences to
Initialize Display).
- For PSR we need to keep the AUX power well enabled.
- On ICL combo PHY ports (non-TC) the AUX power well is needed for
link training too: while the port is enabled with a DP link training
test pattern trying to toggle the AUX power well will time out.
- On ICL MG PHY ports (TC) the AUX power well is needed also for main
link functionality (both in DP and HDMI modes).
- Windows enables these power wells both for main and AUX lane
functionality.
Based on the above take an AUX power reference for main link
functionality too. This makes a difference only on GEN10+ (GLK+)
platforms, where we have separate port specific AUX power wells.
For PSR we still need to distinguish between port A and the other
ports, since on port A DC states must stay enabled for main link
functionality, but DC states must be disabled for driver initiated
AUX transfers. So re-use the corresponding helper from intel_psr.c.
Since we take now a reference for main link functionality on all DP
ports we can forgo taking the separate power ref for PSR functionality.
v2:
- Make sure DC states stay enabled when taking the ref on port A.
(Ville)
v3: (Ville)
- Fix comment about logic for encoders without a crtc state and
add FIXME note for a simplification to avoid calling get_power_domains
in such cases.
- Use intel_crtc_has_dp_encoder() instead !intel_crtc_has_type(HDMI).

If we avoid cleaning up the old state immediately in
intel_atomic_commit_tail() and defer it to a second task, we can avoid
taking heavily contended locks when the caller is ready to procede.
Subsequent modesets will wait for the cleanup operation (either directly
via the ordered modeset wq or indirectly through the atomic helperr)
which keeps the number of inflight cleanup tasks in check.
As an example, during reset an immediate modeset is performed to disable
the displays before the HW is reset, which must avoid struct_mutex to
avoid recursion. Moving the cleanup to a separate task, defers acquiring
the struct_mutex to after the GPU is running again, allowing it to
complete. Even in a few patches time (optimist!) when we no longer
require struct_mutex to unpin the framebuffers, it will still be good
practice to minimise the number of contention points along reset. The
mutex dependency still exists (as one modeset flushes the other), but in
the short term it resolves the deadlock for simple reset cases.

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.

Like we do for encoder let's make the plane->get_hw_state() return
the pipe to which the plane is currently attached. We don't currently
allow planes to move between the pipes, but perhaps one day we will.
In either case this makes the code more uniform and perhaps makes
intel_plane_mapping_ok() slightly more clear.
Note that for i965 and g4x planes A and B still have pipe select bits
but they're hardwired to pipe A and B respectively. This means we can
safely interpret those bits just like on gen2/3. This allows the
same readout code work for plane C (which can still be assigned
to eiter pipe on i965) should we ever expose it.
g4x no longer allows moving the cursor planes between the pipes,
but the pipe select bits can still be set in the register. Thus
we have to ignore those bits. OTOH i965 still allows the cursors
to move between pipes thus we have to trust the bits there.

Let's suppress the underruns around every modeset sequence instead
of trying to avoid it. Planes are disabled at this point anyway so
we don't really gain anything from keeping the underrun reporting
enabled. Also for PCH ports we already suppress all underruns here
anyway so trying avoid it for the CPU eDP doesn't seem all that
important.
Maybe this gets rid of some lingering spurious underruns?

My ILK seems to generate a spurious PCH underrun with most interlaced
HDMI modes. Add a second vblank wait to avoid it.
We have seen some spurious PCH underruns still in CI as well, some
of which seem to be progressive DP. The logs also point towards some
spurious underrins with progressive HDMI on SNB. While I don't have
a solid explanation for those let's try to kill all the birds with one
stone and always do the double wait.

We can always figure out which pipe is affected by the panel power
sequencer lockout mechanism. So no need for the pipe A fallback
anymore. The only case we may have to worry about is an invalid
port select in the power sequencer, but INVALID_PIPE is just fine
in that case. We'll get the WARN about the bogus pps port select
anyway.

'Pipe CSC enable' bit is more than just deprecated in ICL+, it was
disabled in commit 077ef1f09c ("drm/i915/icl: Don't set pipe
CSC/Gamma in PLANE_COLOR_CTL") for primary and sprite planes as it was
causing those planes to be rendered as always black but it was not
disabled in cursor plane, also causing it to be rendered as black.
As mentioned in the commit referenced above, this is a workaround
too and the CSC and gamma per plane values needs to be setup before
enable CSC and gamma again.

For all platforms that run haswell_crtc_enable, our spec tells us to
configure the transcoder clocks and do link training before it tells
us to set pipeconf and the other pipe/transcoder/plane registers.
Starting from Icelake, we get machine hangs if we try to touch the
pipe/transcoder registers without having the clocks configured and not
having some chicken bits set. So this patch changes
haswell_crtc_enable() to issue the calls at the appropriate order
mandated by the spec.
While setting the appropriate chicken bits would also work here, it's
better if we actually program the hardware the way it is intended to
be programmed. And the chicken bit also has some theoretical downsides
that may or may not affect us. Also, correctly programming the
hardware does not prevent us from setting the chicken bits in a later
patch in case we decide to.
v2: Don't forget link training (Ville).

During state readout we first read out the pipe src size, store
that information in the user mode h/vdisplay, but later on we overwrite
that with the actual crtc timings. That makes our read out crtc state
inconsistent with itself when the BIOS has enabled the panel fitter to
scale the pipe contents. Let's preserve the pipe src size based
information in the user mode to make things consistent again.
This fixes a problem introduced by commit a2936e3d9a ("drm/i915:
Use drm_mode_get_hv_timing() to populate plane clip rectangle")
where the inconsistent state is now leading the plane clipping code
to report a failure on account the plane dst coordinates not matching
the user mode size. Previously we did the plane clipping based on
the pipe src size instead and thus never noticed the inconsistency.
The failure manifests as a WARN:

v6: Rebased (me)

Previous version, where a split of calculation
was done, was wrong. Fixed that issue here.

Alignment issues fixed.
When call to skl_update_scaler is made, 0 was being
sent instead of pixel_format.
When crtc update scaler is called, we dont have the
fb to derive the pixel format. Added the function
parameter bool plane_scaler_check to account for this.
v12: Fixed failure in IGT debugfs_test.
fb is NULL in skl_update_scaler_plane
Due to this, accessing fb->format caused failure.
Patch checks fb before using.
v13: In the previous version there was a flaw.
In skl_update_scaler during plane_scaler_check
if the format was non-NV12, it would set need_scaling
to false. This could reset the previously set need_scaling
from a previous condition check. Patch fixes this.
Patch also adds minimum src height for YUV 420 formats
to 16 (as defined in BSpec) and adds for checking this
range.
v14: Addressed review comments from Maarten
Just add a check for NV12 min src height in
skl_update_scaler and retain the remaining checks
as is. Added Reviewed By from Juha-Pekka Heikkila.
v15: Rebased the series.
v16: Changed fb height restriction to be >= 16 as per
Bspec. Earlier it was > 16.
v17: Adding src width and height to be mult of 4 restriction
to avoid pipe fifo underruns for NV12.

DRM_IOCTL_MODE_CURSOR results in frontbuffer flush before the cursor
plane MMIOs are written to. But this flush should not be necessary for
PSR as hardware tracking triggers PSR exit when MMIOs are written. As
for FBC, the spec says "Flips or changes to plane size and panning" cause
FBC to be nuked. Use origin == ORIGIN_FLIP so that features can ignore
cursor updates in their frontbuffer_flush implementations.

"Compressing: yes" when I move the cursor around.

i915_gem_obj_pin_to_display() calls frontbuffer_flush with origin set to
DIRTYFB. The callers however are at a vantage point to decide if hardware
frontbuffer tracking can do the flush for us. For example, legacy cursor
updates, like flips, write to MMIO registers, which then triggers PSR flush
by the hardware. Moving frontbuffer_flush out will enable us to skip a
software initiated flush by setting origin to FLIP. Thanks to Chris for the
idea.

On GLK the plane CSC controls moved into the COLOR_CTL register.
Update the code to progam the YCbCr->RGB CSC mode correctly when
faced with an YCbCr framebuffer.
The spec is rather confusing as it calls the mode "YUV601 to RGB709".
I'm going to assume that just means it's going to use the YCbCr->RGB
matrix as specified in BT.601 and doesn't actually change the gamut.

As only a subset of primary planes are FBC capable there's no need
to waste fences on all of them. So let's skip the fence if the plane
isn't even fbc capable.
In the future we might extend this to skip the fence even for FBC
capable planes if the crtc and/or plane state isn't suitable
for FBC.

Currently we pin a fence on every plane doing tiled scanout. The
number of planes we have available is fast apporaching the number
of fences so we really should stop wasting them. Only FBC needs
the fence on gen4+, so let's use fences only for the primary planes
on those platforms.
v2: drop the tiling check from plane_uses_fence() as the obj is
NULL during initial_plane_config() and we don't rally need the
check since i915_vma_pin_fence() does the check anyway

We want to de-emphasize the link between the request (dependency,
execution and fence tracking) from GEM and so rename the struct from
drm_i915_gem_request to i915_request. That is we may implement the GEM
user interface on top of requests, but they are an abstraction for
tracking execution rather than an implementation detail of GEM. (Since
they are not tied to HW, we keep the i915 prefix as opposed to intel.)
In short, the spatch:
@@
@@
- struct drm_i915_gem_request
+ struct i915_request
A corollary to contracting the type name, we also harmonise on using
'rq' shorthand for local variables where space if of the essence and
repetition makes 'request' unwieldy. For globals and struct members,
'request' is still much preferred for its clarity.

i965 and g4x still have the pipe select bits in the plane control
registers, they're just hardcoded to select a specific pipe. However
plane C on i965 can still move between the pipes, thus we should
program the pipe select bits on i965 if we want to expose plane C
some day.
Since there is no harm in programming the bits on any plane on
i965/g4x let's just always set them. This will also make our
pre-computed register value match what the hardware register
would read, should we want to cross check the two.

G4x cursor control registers still allow us to write to the pipe select
bits even though cursors are supposed to be fixed to a specific pipe.
Bspec tells us that we should only ever write 0 to these bits. Let's
follow that recommendation. On ilk+ the bits become hardwired to 0.
Also looks like ICL repurposes these bits for some other use, so
we had better stop setting them to bogus values there.

Deprecate the silly I915_SET_COLORKEY_NONE flag. The obvious
way to disable colorkey is to just set flags to 0, which is
exactly what the intel ddx has been doing all along.
Currently when userspace sets the flags to 0, we end up in a
funny state where colorkey is disabled, but various colorkey
vs. scaling checks still consider colorkey to be enabled, and
thus we don't allow plane scaling to kick in.
In case there is some other userspace out there that actually
uses this flag (unlikely as this is an i915 specific uapi)
we'll keep on accepting it.

While running the kms_plane clipping test I noticed a similar problem to
the one described in Display WA #1175. In this case, similarly for
planes other than the cursor, with 1 or 3 pixels visible from the left
edge of the screen to the end of the plane and an odd plane X offset
used for clipping causes the same kind of underflow and display
corruption as described for WA #1175. Fix this in a similar way as that
WA rejecting planes ending <4 pixels from the left screen edge.

As described in the WA on GLK and CNL planes on the right edge of the
screen that have less than 4 pixels visible from the beginning of the
plane to the edge of the screen can cause FIFO underflow and display
corruption.
On GLK/CNL I could trigger the problem only if the plane was at the same
time also aligned to the top edge of the screen (after clipping) and
there were exactly 2 pixels visible from the start of the plane to the
right edge of the screen (so couldn't trigger it with 1 or 3 pixels
visible). Nevertheless, to be sure, I also applied the WA for these cases.
I also couldn't see any problem with the cursor plane and later Art
confirmed that it's not affected, so the WA is applied only for the
other plane types.
v2:
- Use -ERANGE instead of -EINVAL. (Chris)

We never support certain mode flags etc. Reject those early on in the
mode_config.mode_valid() hook. That allows us to remove some duplicated
checks from the connector .mode_valid() hooks, and it guarantees that
we never see those flags even from user mode as the
mode_config.mode_valid() hooks gets executed for those as well.

In order to guarantee that pipe_src_w/h matches the user mode h/vdisplay
we must not adjust pipe_src_w to accommodate double wide/dual link.
Instead just reject the mode outright.

Allow sprites to scan out compressed framebuffers.
Since different platforms have a different set of planes that
support CCS let's add a small helper to determine whether a
specific plane supports CCS or not. Currently that information
is spread around in many places, and not all the pieces of
code even agree with each other.
In addition to allowing sprites to scan out compressed fbs,
the other fix here is that we stop rejecting them on pipe C
on CNL.

Watching a light workload on Baytrail (running glxgears and a 1080p
decode), instead of the system remaining at low frequency, the glxgears
would regularly trigger waitboosting after which it would have to spend
a few seconds throttling back down. In this case, the waitboosting is
counter productive as the minimal wait for glxgears doesn't prevent it
from functioning correctly and delivering frames on time. In this case,
glxgears happens to almost always be waiting on the current request,
which we already expect to complete quickly (see i915_spin_request) and
so avoiding the waitboost on the active request and spinning instead
provides the best latency without overcommitting to upclocking.
However, if the system falls behind we still force the waitboost.
Similarly, we will also trigger upclocking if we detect the system is
not delivering frames on time - again using a mechanism that tries to
detect a miss and not preemptively upclock.
v2: Also skip boosting for after missed vblank if the desired request is
already active.

This patch adds the framework required to add HDCP support to intel
connectors. It implements Aksv loading from fuse, and parts 1/2/3
of the HDCP authentication scheme.
Note that without shim implementations, this does not actually implement
HDCP. That will come in subsequent patches.

- drm_hdcp.c under MIT license (Daniel)
- Move intel_hdcp_disable() call above ddi_disable (Ram)
- Fix // comments (I wore a cone of shame for 12 hours to atone) (Daniel)
- Justify intel_hdcp_shim with comments (Daniel)
- Fixed async locking issues by adding hdcp_mutex (Daniel)
- Don't alter connector_state in enable/disable (Daniel)
Changes in v3:
- Added hdcp_mutex/hdcp_value to make async reasonable
- Added hdcp_prop_work to separate link checking & property setting
- Added new helper for atomic_check state tracking (Daniel)
- Moved enable/disable into atomic_commit with matching helpers
- Moved intel_hdcp_check_link out of all locks when called from dp
- Bumped up ksv_fifo timeout (noticed failure on one of my dongles)
Changes in v4:
- Remove SKL_ prefix from most register names (Daniel)
- Move enable/disable back to modeset path (Daniel)
- s/get_random_long/get_random_u32/ (Daniel)
- Remove mode_config.mutex lock in prop_work (Daniel)
- Add intel_hdcp_init to handle init of conn components (Daniel)
- Actually check return value of attach_property
- Check Bksv is valid before trying to authenticate (Ram)
Changes in v5:
- checkpatch whitespace changes
- s/DRM_MODE_CONTENT_PROTECTION_OFF/DRM_MODE_CONTENT_PROTECTION_UNDESIRED/

We have plenty of global registers and whatnot programmed without
any further locking by the modeset code. Currently non-bocking
modesets are allowed to execute in parallel which could corrupt
said registers.
To avoid the problem let's run all non-blocking modesets on an
ordered workqueue. We still put page flips etc. to system_unbound_wq
allowing page flips on one pipe to execute in parallel with page flips
or a modeset on a another pipe (assuming no known state is shared
between them, at which point they would have been added to the same
atomic commit and serialized that way).
Blocking modesets are already serialized with each other by
connection_mutex, and thus are safe. To serialize them with
non-blocking modesets we just flush the workqueue before executing
blocking modesets.

Cleaning up one small piece of the atomic conversion cruft at the time
...
Quick explanation on why the plane->fb assignment is ok to delete: The
core code takes care of the refcounting and legacy ->fb pointer
updating, but drivers are allowed to update it ahead of time. Most
legacy modeset drivers did that as part of their set_config callback
(since that's how the legacy/crtc helpers worked). In i915 we only
need that to make the fbc code happy.
v2: don't nuke the assignement of intel_crtc->config, I accidentally
set CI ablaze :-) Spotted by Maarten. And better explain why nuking
the ->fb assignement shouldn't set off alarm bells.

We should make sure the pipe has fully started when we enable it from
the i830 "power well". Otherwise theoretically i830 could also hit
problems with vblank timestamps jumping around (since we skip the
wait during modeset on i830). Additionally moving planes between the
pipes etc. might not work correctly until both pipes are actually up and
running.

Previously I was under the impression that the scanline counter
reads 0 when the pipe is off. Turns out that's not correct, and
instead the scanline counter simply stops when the pipe stops, and
it retains it's last value until the pipe starts up again, at which
point the scanline counter jumps to vblank start.
These jumps can cause the timestamp to jump backwards by one frame.
Since we use the timestamps to guesstimage also the frame counter
value on gen2, that would cause the frame counter to also jump
backwards, which leads to a massice difference from the previous value.
The end result is that flips/vblank events don't appear to complete as
they're stuck waiting for the frame counter to catch up to that massive
difference.
Fix the problem properly by actually making sure the scanline counter
has started to move before we assume that it's safe to enable vblank
processing.

i830_disable_pipe() gets called from the power well code, and thus
we're already holding the power domain mutex. That means we can't
call plane->get_hw_state() as it will also try to grab the
same mutex and will thus deadlock.
Replace the assert_plane() calls (which calls ->get_hw_state()) with
just raw register reads in i830_disable_pipe(). As a bonus we can
now get a warning if plane C is enabled even though we don't even
expose it as a drm plane.

Previously we would enable hotplug polling on the outputs immediately
upon construction. This would allow a very early hotplug event to
trigger before we had finishing setting up the driver to handle it.
Instead, move the output polling to the last step of registration, after
we have set up all handlers, including the fbdev configuration.
v2: Symmetrically turnoff the hotplug helper in unregister after the
fbdev is first synchronised then finalized. This stops a late hotplug
event being processed after the interrupts are disabled.

Unify the plane disabling during state readout by pulling the code into

diabled.
Additonally we change the plane<->pipe mapping sanitation to work by
simply disabling the offending planes instead of entire pipes. And
we do it before we otherwise sanitize the crtcs, which means we don't
have to worry about misassigned planes during crtc sanitation anymore.

Display is not sending a PMRsp when a PMReq is received
at the same time that all planes are turned off.
State machine in the dcprunit is stuck in the WAIT4DONE
state which means that there is no fill_done.
WA: disable arbiter clock gating, set bit [27] of 0x46530
v2: As Ville pointed out, based on the description the issue
can happen when disabling the planes, similar to
WaRsPkgCStateDisplayPMReq:hsw
Also description of the issue was updated on commit
message to make it more clear that we need this

We no longer use intel_crtc->wm.active for watermarks any more,
which was incorrect. But this uncovered a bug in sanitize_watermarks(),
which meant that we wrote the correct watermarks, but the next
update would still use the wrong hw watermarks for calculating.
This caused all further updates to fail with -EINVAL and the
log would reveal an error like the one below:

Apparently setting up a bunch of GT registers before we've properly
initialized the rest of the GT hardware leads to these setting being
lost. So looks like I broke HSW with commit b7048ea12f ("drm/i915:
Do .init_clock_gating() earlier to avoid it clobbering watermarks")
by doing init_clock_gating() too early. This should actually affect
other platforms as well, but apparently not to such a great degree.
What I was ultimately after in that commit was to move the
ilk_init_lp_watermarks() call earlier. So let's undo the damage and
move init_clock_gating() back to where it was, and call
ilk_init_lp_watermarks() just before the watermark state readout.
This highlights how fragile and messed up our init order really is.
I wonder why we even initialize the display before gem. The opposite
order would make much more sense to me...
v2: Keep WaRsPkgCStateDisplayPMReq:hsw early as it really must

Currently the DDI encoder->type will change at runtime depending on
what kind of hotplugs we've processed. That's quite bad since we can't
really trust that that current value of encoder->type actually matches
the type of signal we're trying to drive through it.
Let's eliminate that problem by declaring that non-eDP DDI port will
always have the encoder type as INTEL_OUTPUT_DDI. This means the code
can no longer try to distinguish DP vs. HDMI based on encoder->type.
We'll leave eDP as INTEL_OUTPUT_EDP, since it'll never change and
there's a bunch of code that relies on that value to identify eDP
encoders.
We'll introduce a new encoder .compute_output_type() hook. This allows
us to compute the full output_types before any encoder .compute_config()
hooks get called, thus those hooks can rely on output_types being
correct, which is useful for cloning on oldr platforms. For now we'll
just look at the connector type and pick the correct mode based on that.
In the future the new hook could be used to implement dynamic switching
between LS and PCON modes for LSPCON.

Rather than having the caller of .get_config() set output_types based on
encoder->type, let's just have .get_config() itself populate

On CNL we may need to bump up the system agent voltage not only due
to CDCLK but also when driving DDI port with a sufficiently high clock.
To that end start tracking the minimum acceptable voltage for each crtc.
We do the tracking via crtcs because we don't have any kind of encoder
state. Also there's no downside to doing it this way, and it matches how
we track cdclk requirements on account of pixel rate.
v2: Allow disabled crtcs to use the min voltage
Add IS_CNL check to intel_ddi_compute_min_voltage() since
we're using CNL specific values there

Reuse the normal state readout code to get the fixed mode for LVDS/DVO
encoders. This removes some partially duplicated state readout code
from LVDS/DVO encoders. The duplicated code wasn't actually even
populating the negative h/vsync flags, leading to possible state checker
complaints. The normal readout code populates that stuff fully.

Following the pattern now used for obj->mm.pages, use just pin_fence and

On GLK and CNL enabling a pipe with its pipe scaler enabled will result
in a FIFO underrun. This happens only once after driver loading or
system/runtime resume, more specifically after power well 1 gets
enabled; subsequent modesets seem to be free of underruns. The BSpec
workaround for this is to disable the pipe scaler clock gating for the
duration of modeset. Based on my tests disabling clock gating must be
done before enabling pipe scaling and we can re-enable it after the pipe
is enabled and one vblank has passed.
For consistency I also checked if plane scaling would cause the same
problem, but that doesn't seem to trigger this problem.
The patch is based on an earlier version from Ander.

- Set also CLKGATE_DIS_PSL bits 8 and 9.

By always keeping track of the last commit in plane_state, we know
whether there is an active update on the plane or not. With that
information we can reject the fast update, and force the slowpath
to be used as was originally intended.
We cannot use plane_state->crtc->state here, because this only mentions
the most recent commit for the crtc, but not the planes that were part
of it. We specifically care about what the last commit involving this
plane is, which can only be tracked with a pointer in the plane state.
Changes since v1:
- Clean up the whole function here, instead of partially earlier.
- Add mention in the commit message why we need commit in plane_state.
- Swap plane->state in intel_legacy_cursor_update, instead of
reassigning all variables. With this commit We know that the cursor
is not part of any active commits so this hack can be removed.

[mlankhorst: Amend commit for merge conflicts with drm-intel]
Currently we neatly track the crtc state, but forget to look at
plane/connector state.
When doing a nonblocking modeset, immediately followed by a setprop
before the modeset completes, the setprop will see the modesets new
state as the old state and free it.
This has to be solved by waiting for hw_done on the connector, even
if it's not assigned to a crtc. When a connector is unbound we take
the last crtc commit, and when it stays unbound we create a new
fake crtc commit for that gets signaled on hw_done for all the
planes/connectors.
We wait for it the same way as we do for crtc's, which will make
sure we never run into a use-after-free situation.

- Only create a single disable commit. (danvet)

This patch adds IPC support. This patch also enables IPC in all supported
platforms based on has_ipc flag.
IPC (Isochronous Priority Control) is the hardware feature, which
dynamically controls the memory read priority of Display.
When IPC is enabled, plane read requests are sent at high priority until
filling above the transition watermark, then the requests are sent at
lower priority until dropping below the level 0 watermark.
The lower priority requests allow other memory clients to have better
memory access. When IPC is disabled, all plane read requests are sent at
high priority.

- Remove commandline parameter to disable ipc
- Address Paulo's comments

Currently the .modeset_calc_cdclk() hooks check the final cdclk value
against the max allowed. That's not really sufficient since the low
level calc_cdclk() functions effectively clamp the minimum required
cdclk to the max supported by the platform. Hence if the minimum
required exceeds the platforms capabilities we'd keep going anyway
using the max cdclk frequency.
To fix that let's move the check earlier into
intel_crtc_compute_min_cdclk() and we'll check the minimum required
cdclk of the pipe against the maximum supported by the platform.

Make the min_pixclk thing less confusing by changing it to track
the minimum acceptable cdclk frequency instead. This means moving
the application of the guardbands to a slightly higher level from
the low level platform specific calc_cdclk() functions.
The immediate benefit is elimination of the confusing 2x factors
on GLK/CNL+ in the audio workarounds (which stems from the fact
that the pipes produce two pixels per clock).
v2: Keep cdclk higher on CNL to workaround missing DDI clock voltage handling

The CCS won't have the same stride as the main surface anyway so trying
to guard against the fence stride not matching the CCS stride is
not sensible. Just skip the fence vs. fb alignment check for the aux
plane.

Oneshot disabling of IPS when CRC capturing is started is insufficient.
IPS may get re-enabled by any plane update, and hence tests that keep
CRC capturing on across plane updates will start to see inconsistent
results as soon as IPS kicks back in. Add a new knob into the crtc state
to make sure IPS stays disabled as long as CRC capturing is enabled.
Forcing a modeset is the easiest way to handle this since that's already
how we do the panel fitter workaround. It's a little heavy handed just
for IPS, but seeing as we might already do the panel fitter workaround
I think it's better to follow that. We migth want to optimize both cases
later if someone gets too upset by the extra delay from the modeset.
v2: Check the right thing when deciding whether to force a modeset
v3: Rebase, check HAS_IPS before forcing a modeset,
move ips_force_disable check into pipe_config_supports_ips()

If we miss the current vblank because the gpu was busy, that may cause a
jitter as the frame rate temporarily drops. We try to limit the impact
of this by then boosting the GPU clock to deliver the frame as quickly
as possible. Originally done in commit 6ad790c0f5 ("drm/i915: Boost GPU
frequency if we detect outstanding pageflips") but was never forward
ported to atomic and finally dropped in commit fd3a40242e ("drm/i915:
Rip out legacy page_flip completion/irq handling").
One of the most typical use-cases for this is a mostly idle desktop.
Rendering one frame of the desktop's frontbuffer can easily be
accomplished by the GPU running at low frequency, but often exceeds
the time budget of the desktop compositor. The result is that animations
such as opening the menu, doing a fullscreen switch, or even just trying
to move a window around are slow and jerky. We need to respond within a
frame to give the best impression of a smooth UX, as a compromise we
instead respond if that first frame misses its goal. The result should
be a near-imperceivable initial delay and a smooth animation even
starting from idle. The cost, as ever, is that we spend more power than
is strictly necessary as we overestimate the required GPU frequency and
then try to ramp down.
This of course is reactionary, too little, too late; nevertheless it is
surprisingly effective.

Future platforms increase the number of power wells which require
additional control registers. A convenient way to select the correct
register is to use the high bits of the power well ID as index. This
patch only prepares for this, while upcoming platform enabling patches
will add the actual new power well IDs and corresponding power well
control registers.
