Prepared substructure rps for RPS related state. autoenable_work is
used for RC6 too hence it is defined outside rps structure. As we do
this lot many functions are refactored to use intel_rps *rps to access
rps related members. Hence renamed intel_rps_client pointer variables
to rps_client in various functions.
v2: Rebase.

For certain platforms on certain encoders, timings are driven
from port instead of pipe. Thus, we can't rely on pipe scanline
registers to get the timing information. Some cases scanline
register read will not be functional.
This is causing vblank evasion logic to fail since it relies on
scanline, causing atomic update failure warnings.
This patch uses pipe framestamp and current timestamp registers
to calculate scanline. This is an indirect way to get the scanline.
It helps resolve atomic update failure for gen9 dsi platforms.
v2: Addressed Ville and Daniel's review comments. Updated the
register MACROs, handled race condition for register reads,
extracted timings from the hwmode. Removed the dependency on
crtc->config to get the encoder type.
v3: Made get scanline function generic
v4: Addressed Ville's review comments. Added a flag to decide timestamp
based scanline reporting. Changed 64bit variables to u32
v5: Adressed Ville's review comments. Put the scanline compute function
at the place of caller. Removed hwmode flags from uapi and used a local
i915 data structure instead.
v6: Used vblank hwmode to get the timings.
v7: Fixed sparse warnings, indentation and minor review comments.
v8: Limited this only for Gen9 DSI.

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.
Changes since V1:
- Remove commandline parameter to disable ipc
- Address Paulo's comments
Changes since V2:
- Address review comments
- Set ipc_enabled flag
Changes since V3:
- move ipc_enabled flag assignment inside intel_ipc_enable function
Changes since V4:
- Re-enable IPC after suspend/resume
Changes since V5:
- Enable IPC for all gen >=9 except SKL
Changes since V6:

- after resume program IPC based on SW state.

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,

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.

Merge tag 'drm-for-v4.13' into drm-intel-next-queued
Resync with the main drm-next pull request for 4.13. What we really
need is to fully resync with pending drm-misc, but that's not yet
possible due to the still ongoing merge window.

Once a client has requested a waitboost, we keep that waitboost active
until all clients are no longer waiting. This is because we don't
distinguish which waiter deserves the boost. However, with the advent of
fence signaling, the signaler threads appear as waiters to the RPS
interrupt handler. So instead of using a single boolean to track when to
keep the waitboost active, use a counter of all outstanding waitboosted
requests.
At this point, I have removed all vestiges of the rate limiting on
clients. Whilst this means that compositors should remain more fluid,
it also means that boosts are more prevalent. See commit b29c19b645
("drm/i915: Boost RPS frequency for CPU stalls") for a longer discussion
on the pros and cons of both approaches.
A drawback of this implementation is that it requires constant request
submission to keep the waitboost trimmed (as it is now cancelled when the
request is completed). This will be fine for a busy system, but near
idle the boosts may be kept for longer than desired (effectively tens of
vblanks worstcase) and there is a reliance on rc6 instead.

BackMerge tag 'v4.12-rc5' into drm-next
Linux 4.12-rc5 for nouveau fixes
830 more or less requires both pipes and DPLLs to remain on as long
as either pipe is needed. However, when neither pipe is actually needed,
we can save a bit of power by turning everything off. To do that we add
a new "power well" that turns both pipes and DPLLs on and off in the
right order. Seems to save ~50mW on my Fujitsu-Siemens Lifebook S6010.
This also avoids having to abuse the load detection to force pipe A on
at init time. That was never very robust, and it only worked for one
pipe, whereas 830 really needs both pipes enabled. As a bonus the 830
pipe quirk is now a bit more isolated from the rest of the mode setting
infrastructure, which should mean that it's much less likely someone
will accidentally break it in the future. The extra cost is of course
slight code duplication, but that seems like a worthwile tradeoff here.

A display resolution is only supported if it meets all the restrictions
below for Maximum Pipe Pixel Rate.
The display resolution must fit within the maximum pixel rate output
from the pipe. Make sure that the display pipe is able to feed pixels at
a rate required to support the desired resolution.
For each enabled plane on the pipe {
If plane scaling enabled {
Horizontal down scale amount = Maximum[1, plane horizontal size /
scaler horizontal window size]
Vertical down scale amount = Maximum[1, plane vertical size /
scaler vertical window size]
Plane down scale amount = Horizontal down scale amount *
Vertical down scale amount
Plane Ratio = 1 / Plane down scale amount
}
Else {
Plane Ratio = 1
}
If plane source pixel format is 64 bits per pixel {
Plane Ratio = Plane Ratio * 8/9
}
}
Pipe Ratio = Minimum Plane Ratio of all enabled planes on the pipe
If pipe scaling is enabled {
Horizontal down scale amount = Maximum[1, pipe horizontal source size /
scaler horizontal window size]
Vertical down scale amount = Maximum[1, pipe vertical source size /
scaler vertical window size]
Note: The progressive fetch - interlace display mode is equivalent to a
2.0 vertical down scale
Pipe down scale amount = Horizontal down scale amount *
Vertical down scale amount
Pipe Ratio = Pipe Ratio / Pipe down scale amount
}
Pipe maximum pixel rate = CDCLK frequency * Pipe Ratio
In this patch our calculation is based on pipe downscale amount
(plane max downscale amount * pipe downscale amount) instead of Pipe
Ratio. So,
max supported crtc clock with given scaling = CDCLK / pipe downscale.
Flip will fail if,
current crtc clock > max supported crct clock with given scaling.

SDVO was the last connector that's still using the legacy paths
for properties, and this is with a reason!
This connector implements a lot of properties dynamically,
and some of them shared with the digital connector state,
so sdvo_connector_state subclasses intel_digital_connector_state.
set_property had a lot of validation, but this is handled in the
drm core, so most of the validation can die off. The properties
are written right before enabling the connector, since there is no
good way to update the properties without crtc.

intel_hdmi supports 3 properties, force_audio, broadcast rgb and
scaling mode. The last one is only created for eDP, so the is_eDP
in set_property is not required.
panel fitting and broadcast rgb are straightforward and only requires
changing compute_config.
force_audio is also used to force DVI mode, which means changes to
compute_config and mode_valid. mode_valid is called with
connection_mutex held, so it can safely dereference connector->state.

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.

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.
