Ville Syrjälä 449059a969 drm/i915: Consult aux_ch instead of port in ->get_aux_clock_divider()
While it seems totally unlikely that any system would mix a cpu/north
aux channel with a pch/south port (or vice versa) we should still
consult intel_dp->aux_ch rather than encoder->port when figuring out
which clock is actually used by the aux ch.

Mustamin B Mustaffa 73c0fcac97 drm/i915: Enable VBT based BL control for DP
Currently, BXT_PP is hardcoded with value '0'.
It practically disabled eDP backlight on MRB (BXT) platform.

This patch will tell which BXT_PP registers (there are two set of
PP_CONTROL in the spec) to be used as defined in VBT (Video Bios Timing
table) and this will enabled eDP backlight controller on MRB (BXT)
platform.

v2:
 - Remove unnecessary information in commit message.
 - Assign vbt.backlight.controller to a backlight_controller variable and
   return the variable value.
v3:
 - Rebased to latest code base.
 - updated commit title.

Ramalingam C 791a98dd9b drm/i915: Detect panel's hdcp capability
DP HDCP1.4 spec mandates that An can be written to panel only after
detecting the panel's hdcp capability.

For HDMI valid BKSV indicates the panel's hdcp capability.

For HDMI it is optional to detect the panel's hdcp capability before
An Write.

  Added comments explaining the need for action [Seanpaul].
  Made panel's hdcp capability detection optional for hdmi [Seanpaul].
  Defined a func for reading bcaps for DP [Seanpaul].

v2: Simplify the code. Remove unwanted register definitions.
Make code as close to BXT style as possible. (Ville)
Also, remove the use of ICP_SECOND_PPS_BACKLIGHT for now.
Moving forward, if we are sure we need to set this register,
we can access it.

v3: Use INTEL_GEN(dev_priv), make code more readeable. (Ville)

v4 (from Paulo):
 - Coding style fixes.
 - Add a missing HAS_PCH_CNP -> gen10+ check.
 - Rebase.

v5: Use per platform checks rather than INTEL_GEN().
    v4 of this patch breaks on CoffeeLake, since CFL uses
    CNP and per platform check makes sense in that case.

v6 (from Paulo):
 - v5 was a patch on top of v4, not a new version. Now v6 is correctly

Sean Paul 20f24d776d drm/i915: Implement HDCP for DisplayPort
This patch adds HDCP support for DisplayPort connectors by implementing
the intel_hdcp_shim.

Most of this is straightforward read/write from/to DPCD registers. One
thing worth pointing out is the Aksv output bit. It wasn't easily
separable like it's HDMI counterpart, so it's crammed in with the rest
of it.

Changes in v2:
- Moved intel_hdcp_check_link out of intel_dp_check_link and only call
  it on short pulse. Since intel_hdcp_check_link does its own locking,
  this ensures we don't deadlock when intel_dp_check_link is called
  holding connection_mutex.
- Rebased on drm-intel-next
Changes in v3:
- Initialize new worker
Changes in v4:
- Use intel_hdcp_init (Daniel)
- Check for reauth requests in check_link (Ram)
Changes in v5:
- None
Changes in v6:
- Fix build warnings when printing ssize_t

Ville Syrjälä 0502138933 drm/i915: Interlaced DP output doesn't work on VLV/CHV
Reject interlaced modes on VLV/CHV DP outputs. This simply does
not work correctly in the hardware. We do get some output, but
it's quite corrupted.

The available documentation fails to mention this fact. I
contacted some hardware people who eventually managed to locate
the relevant HSD for VLV, which was resolved by declaring
interlaced DP output as not supported. The HSD was never cloned
for CHV even though it inherited most of the hardware and
thus has the same problems with interlaced DP output.

Imre Deak 5643205c63 drm/i915: Avoid PPS HW/SW state mismatch due to rounding
We store a SW state of the t11_t12 timing in 100usec units but have to
program it in 100msec as required by HW. The rounding used during
programming means there will be a mismatch between the SW and HW states
of this value triggering a "PPS state mismatch" error. Avoid this by
storing the already rounded-up value in the SW state.

Note that we still calculate panel_power_cycle_delay with the finer
100usec granularity to avoid any needless waits using that version of
the delay.

Daniel Vetter 42e5e65765 drm/i915: sync dp link status checks against atomic commmits
Two bits:
- check actual atomic state, the legacy stuff can only be looked at
  from within the atomic_commit_tail function, since it's only
  protected by ordering and not by any locks.

- Make sure we don't wreak the work an ongoing nonblocking commit is
  doing.

v2: We need the crtc lock too, because a plane update might change it
without having to acquire the connection_mutex (Maarten). Use
Maarten's changes for this locking, while keeping the logic that uses
the connection->commit->hw_done signal for syncing with nonblocking
commits.

v3: The initial state objects from the hw state readout do not have a
commit object. Check for that (spotted by CI).

v4: Fix deadlock from jumping to put_power with locks still held.

Ville Syrjälä 8ec47de21b drm/i915: Pass around crtc and connector states for audio
Explicitly pass the crtc and connector states into the audio
code enable/disable hooks, and plumb them all the way down.

This gets rid of almost all crtc->config and encoder->crtc
uses. The one place where we still use them is
i915_audio_component_sync_audio_rate() since that gets called from
the audio driver and we don't have explicit states around then.

Ville Syrjälä 7e732cacb1 drm/i915: Stop frobbing with DDI encoder->type
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.

v2: Fix BXT/GLK PPS explosion with DSI/MST encoders
v3: Avoid the PPS warn on pure HDMI/DVI DDI encoders by checking dp.output_reg
v4: Rebase
v5: Populate output_types in .get_config() rather than in the caller

Jani Nikula 7c838e2a9b drm/i915/edp: read edp display control registers unconditionally
Per my reading of the eDP spec, DP_DPCD_DISPLAY_CONTROL_CAPABLE bit in
DP_EDP_CONFIGURATION_CAP should be set if the eDP display control
registers starting at offset DP_EDP_DPCD_REV are "enabled". Currently we
check the bit before reading the registers, and DP_EDP_DPCD_REV is the
only way to detect eDP revision.

Turns out there are (likely buggy) displays that require eDP 1.4+
features, such as supported link rates and link rate select, but do not
have the bit set. Read the display control registers
unconditionally. They are supposed to read zero anyway if they are not
supported, so there should be no harm in this.

This fixes the referenced bug by enabling the eDP version check, and
thus reading of the supported link rates. The panel in question has 0 in
DP_MAX_LINK_RATE which is only supported in eDP 1.4+. Without the
supported link rates method we default to RBR which is insufficient for
the panel native mode. As a curiosity, the panel also has a bogus value
of 0x12 in DP_EDP_DPCD_REV, but that passes our check for >= DP_EDP_14
(which is 0x03).

This also reduces the code paths you have to think about in the source

Manasi Navare d7ba25bd9e drm/i915/edp: Get the Panel Power Off timestamp after panel is off
Kernel stores the time in jiffies at which the eDP panel is turned
off. This should be obtained after the panel is off (after the
wait_panel_off). When we next attempt to turn the panel on, we use the
difference between the timestamp at which we want to turn the panel on
and timestamp at which panel was turned off to ensure that this is equal
to panel power cycle delay and if not we wait for the remaining
time. Not waiting for the panel power cycle delay can cause the panel to
not turn on giving rise to AUX timeouts for the attempted AUX
transactions.

Ville Syrjälä 1a8ff6076e drm/i915: Reorganize .disable hooks for pre-DDI DP
Most of our DP encoder hooks are split into per-platform variants.
.disable() an exception, and thus it's a bit messy. Let's split it
up as well. We'll leave the common parts in a helper called by
each platform specific hook. Now each platform has mostly its own
hooks. Some hooks are still shared between vlv and chv, and between
g4x and ilk. None of the remaining shared hooks have any platform
checks in them however so duplicating them doesn't seem particularly
useful.

There is a subtle change on VLV/CHV where we now disable PSR before
audio, whereas before we disabled PSR after audio. That should be
totally fine, and PSR is disabled by default anyway. Jani also pointed
out to me that PSR + audio doesn't seem like a particularly realistic
combination.

Rodrigo Vivi 256cfdde42 drm/i915: Simplify hpd pin to port
We will soon need to make that pin port association per
platform, so let's try to simplify it beforehand.

Also we are moving the backwards port to pin
here as well so let's use a standardized way.

One extra possibility here would be to add a
MISSING_CASE along with PORT_NONE, but I don't want
to change this behaviour for now.

Rodrigo Vivi d907b6658a drm/i915/cnl: Add allowed DP rates for Cannonlake.
"Frequencies over 5.4 GHz only supported on certain
DDI ports and SKUs, and requires Vccio >= 0.95V."

More specifically, for current CNL SKUs available
(CNL-U and CNL-Y) we have:

DDI A - 5.4G eDP
DDI B - 8.1G DP
DDI C - 8.1G DP
DDI D - 5.4G DP

v2: Rebase on top of source_rates changes.
v3: Address the max 5.4 x 8.1 per DDI and also consider vccio.

Manasi Navare c99a259b4b drm/i915/edp: Add a T12 panel delay quirk to fix DP AUX CH timeouts
This patch fixes the DP AUX CH timeouts observed during CI IGT
tests thus fixing the CI failures. This is done by adding a
quirk for a particular PCI device that requires the panel power
cycle delay (T12) to be set to 800ms which is 300msecs more than
the minimum value specified in the eDP spec. So a quirk is
implemented for that specific PCI device.

v4:
* Add Bugzilla links for FDO bugs in the commit message (Ville, Jani)
v3:
* Change some comments, specify the delay as 800 * 10 (Ville)
v2:
* Change the function and variable names to from PPS_T12_
to _T12 since it is a T12 delay (Clint)

Final pile of features for 4.13

New uabi:

  (Chris Wilson)
- (sub)slice getparam, needed for mesa perf support (Robert Bragg)

First pile of patches for cnl/cfl support, maintained by Rodrigo but
with lots of contributions from others. Still incomplete since public
review still ongoing.

Features/refactoring:
- Make execbuf faster (Chris Wilson), a pile of series to make execbuf
  buffer handling have fewer passes, use less list walking, postpone
  more work to async workers and shuffle buffers less, all to make the
  common case much faster (in some cases at least).
- cold boot support for glk dsi (Madhav Chauhan)
- Clean up pipe A quirk and related old platform hacks (Ville)
- perf sampling support for kbl/glk (Lionel)
- perf cleanups (Robert Bragg)
- wire atomic state to backlight code, to avoid pipe lookup hacks
  (Maarten)
- reduce request waiting latency/overhead to remove the spinning and
  associated cpu cycle wasting (Chris)
- fix 90/270 rotation wm computation (Ville)
- new ddb allocation algo for skl (Kumar Mahesh)
- fix regression due to system suspend optimiazatino (Imre)
- the usual pile of small cleanups and refactors all over

GVT updates contained in this tag:
- optimization for per-VM mmio save/restore (Changbin)
- optimization for mmio hash table (Changbin)
- scheduler optimization with event (Ping)
- vGPU reset refinement (Fred)
