After registering the audio component in i915_audio_component_init()
the audio driver may call i915_audio_component_get_power() via the
component ops. This could program AUD_FREQ_CNTRL with an uninitialized
value if the latter function is called before display.audio.freq_cntrl
gets initialized. The get_power() function also does a modeset which in
the above case happens too early before the initialization step and
triggers the
"Reject display access from task"
error message added by the Fixes: commit below.
Fix the above issue by registering the audio component only after the
initialization step.

WA_14020863754: Corner case with Min Hblank Fix can cause
audio hang
Issue: Previously a fix was made to avoid issues with extremely
small hblanks, called the "Min Hblank Fix". However, this can
potentially cause an audio hang.
Workaround :
During "Audio Programming Sequence" Audio Enabling -
When DP mode is enabled Set mmio offset 0x65F1C bit 18 = 1b,
before step #1 "Enable audio Presence Detect"
During "Audio Programming Sequence" Audio Disabling -
When DP mode is enabled Clear mmio offset 0x65F1C bit 18 = 0b,
after step #6 "Disable Audio PD (Presence Detect)"
If not clearing PD bit, must also not clear 0x65F1C bit 18 (leave = 1b)

Intel hardware is capable of programming the Maud/Naud SDPs on its

of any deviations from the theoretical values. Programming the registers
explicitly with static values can interfere with this logic. Therefore,

If we have to force the hardware to go through a full modeset
due to eg. cdclk reprogramming, we need to preserve
crtc_state->inherited for all crtcs that have not otherwise
gone through the whole compute_config() stuff after connectors
have been detected.
Otherwise eg. cdclk induced modeset glk_force_audio_cdclk()
will clear the inherited flag, and thus the first real commit
coming from userspace later on will not be forced through
the full .compute_config() path and so eg. audio state may
not get properly recomputed.
But instead of adding all kinds of ad-hoc crtc_state->inherited
preservation hacks all over, let's change things so that we
only clear it for the crtcs directly included in userspace/client
initiated commits.
Should be far less fragile since now we just need to remember
to flag the internal commits, and not worry about where new
crtcs might get pulled in.

The audio logic lives in the transcoder rather than the pipe,
so start tracking it like that.
This is only really important for bigjoiner cases where tracking
by pipe doesn't work at all since intel_audio_codec_{enable,disable}()
won't even be called for the slave pipe. This means the state
checker won't find the ELD for the slave pipe and gets upset.
The PD->has_audio readout does currently work since that gets
read out from the same transcoder for both pipes.
For other cases this doesn't actually matter since it's only
the normal pipe transcoders that are audio capable, whereas
the more special transcoders (EDP/DSI) are not.

Since we use the audio component to transfer the ELD to the audio
driver on hsw+ platforms there is no point in even programming
the hardware ELD buffer. Stop doing so.
The one slight caveat here is that this is not strictly legal
according to the HDA spec. PD=1;ELD=0 is only documented as
an intermediate state during modeset. But if there is no hardware
that depends on that then I guess we're fine. Or we could
perhaps set ELD=1 without actually programming the buffer?
Note that the bspec sequence of PD=0;ELD=0 -> PD=1;ELD=0 ->
PD=1;ELD=1 is also not strictly correct according to the HDA
spec, as the only documented transition from PD=0;ELD=0 is
straight to PD=1;ELD=1.
Additionally on hsw/bdw the hardware buffer is tied in with the
dedicated display HDA controller's power state, so currently
we mostly fail at proramming the buffer anyway. When the HDA
side is not sufficiently powered up the ELD address bits get
stuck and the ELD data register accesses go nowhere.

The FIXMEs are nonsense since we do the audio disable very

enabled when we do this.
TODO not sure we actually want these since we don't even rely

Currently that should not happen since we only do audio
enable/disable from full modesets, and those are fully

audio on/off from fastsets too.
The hsw codepaths already have the same locking.
g4x should not need it since it can only do audio to a

We don't use the audio code on crestline (CL) since it doesn't
support native HDMI output, and SDVO has it's own way of doing
audio.
And Bearlake-C (BLC) doesn't even exist in the real world, so
no point it trying to deal with it.

Rename the 'dev_priv' variables to 'i915' in the audio code
to match modern style conventions.
v2: Drop some needless braces in intel_audio_hooks_init()

Split out audio registers to a header of its own to reduce the size of
i915_reg.h.
TODO: Remove direct audio register access from intel_ddi.c. However,
unification of audio get config is cumbersome due to the audio enable
bit being in the DP or HDMI registers on older platforms.

The audio codec enable/disable debug logging is spread around in callers
and the platform specific hooks. Put them all together in one place on
both the enable and disable paths.

Add display/intel_display_trace.[ch] for defining display
tracepoints. The main goal is to reduce cross-includes between gem and
display. It would be possible split up tracing even further, but that
would lead to more boilerplate.
We end up having to include intel_crtc.h in a few places because it was
pulled in implicitly via intel_de.h -> i915_trace.h -> intel_crtc.h, and
that's no longer the case.
There should be no changes to tracepoints.
v3:
- Rebase
v2:
- Define TRACE_INCLUDE_PATH relative to define_trace.h (Chris)
- Remove useless comments (Ville)
