I broke AVI/HDMI/SPD infoframes on HSW+ with the register type
safety changes. We were supposed to check that the infoframe data
register is valid before writing the infoframe data, but the check
ended up inverted, and so in practice we never wrote or enabled
these infoframes.
We were still sending out the GCP infoframe when the sink was
deep-color capable. That and the fact that we use a single
bool to track our infoframe state meant that the state checker
only caught this when a HDMI sink that doesn't do deep-color was
used.
We really need to fix our infoframe state checking to be much
more anal. But in the meantime let's just fix the regression.
In fact let's just throw out the register validity check and
convert some of the "unknown info frame type" debug messages
into MISSING_CASE(). So far we support the same set of infoframe
types on all platforms, so the silent debug messages make no
sense.

When creating a new (pageable) GEM object and filling it with data, we
must mark it as 'dirty', i.e. backing store is out-of-date w.r.t. the
newly-written content. This ensures that if the object is evicted under

In various places, a single page of a (regular) GEM object is mapped into
CPU address space and updated. In each such case, either the page or the
the object should be marked dirty, to ensure that the modifications are
not discarded if the object is evicted under memory pressure.
The typical sequence is:
va = kmap_atomic(i915_gem_object_get_page(obj, pageno));
*(va+offset) = ...
kunmap_atomic(va);
Here we introduce i915_gem_object_get_dirty_page(), which performs the
same operation as i915_gem_object_get_page() but with the side-effect
of marking the returned page dirty in the pagecache. This will ensure
that if the object is subsequently evicted (due to memory pressure),
the changes are written to backing store rather than discarded.
Note that it works only for regular (shmfs-backed) GEM objects, but (at
least for now) those are the only ones that are updated in this way --
the objects in question are contexts and batchbuffers, which are always
shmfs-backed.
Separate patches deal with the cases where whole objects are (or may
be) dirtied.

Mainly aux communications on sink_crc
were failing a lot randomly on recent platforms.
The first solution was to try to use intel_dp_dpcd_read_wake, but then
it was suggested to move retries to drm level.
Since drm level was already taking care of retries and didn't want
to through random retries on that level the second solution was to
put the retries at aux_transfer layer what was nacked.
So I realized we had so many retries in different places and
started to organize that a bit. During this organization I noticed
that we weren't handing at all the case were the message size was
zeroed. And this was exactly the case that was affecting sink_crc.
Also we weren't respect BSPec who says this size message = 0 or > 20
are forbidden.
It is a fact that we still have no clue why we are getting this
forbidden value there. But anyway we need to handle that for now
so we return -EBUSY and drm level takes care of the retries that
are already in place.
v2: Print debug messsage when this case is reached as suggested
by Jani.
v3: This patch is crucial to make PSR test cases reliably working
on SKL. So split this patch from the aux re-org series and add
a FIXME as a promisse to continue that effort besides reminding
to remove the sleep when that is merged.
v4: Use a bigger usleep range so kernel doesn't need to be interrupted
on a exact time, as suggested by Paulo.
But anyway we should discuss the better time
ranges on the EBUSY handle re-org at drm level since this one here
is temporary.

Based on Chris Wilson's patch from 6 months ago, rebased and adapted.
The current implementation of intel_ring_initialized() is too heavyweight;
it's a non-inlined function that chases several levels of pointers. This
wouldn't matter too much if it were rarely called, but it's used inside
the iterator test of for_each_ring() and is therefore called quite
frequently. So let's make it simple and inline ...
The idea here is to use ring->dev as an indicator showing which engines
have been initialised and are therefore to be included in iterations that
use for_each_ring(). This allows us to avoid multiple memory references
and a (non-inlined) function call on each iteration of each such loop.

This patch adds a reverse mapping from a digital port number to
intel_encoder object containing the corresponding intel_digital_port.
It simplifies the query of the encoder a lot.
Note that, even if it's a valid digital port, the dig_port_map[] might
point still to NULL -- usually it implies a DP MST port. Due to this
fact, the NULL check in each place has no WARN_ON() and just skips the
port. Once when the situation changes in future, we might introduce
WARN_ON() for a more strict check.

Implement a new i915_audio_component_ops, get_eld(). It's called by
the audio driver to fetch the current audio status and ELD of the
given HDMI/DP port. It returns the size of expected ELD bytes if it's
valid, zero if no valid ELD is found, or a negative error code. The
current state of audio on/off is stored in the given pointer, too.
Note that the returned size isn't limited to the given max bytes. If
the size is greater than the max bytes, it means that only a part of
ELD has been copied back.
For achieving this implementation, a new field audio_connector is
added to struct intel_digital_port. It points to the connector
assigned to the given digital port. It's set/reset at each audio
enable/disable call in intel_audio.c, and protected with av_mutex.

When disable_noatomic is called plane_mask is not correct yet, and
plane_state->visible = true is left as true after disabling the primary
plane.
Other planes are already disabled as part of crtc sanitization, only the
primary is left active. But the plane_mask is not updated here. It gets
updated during fb takeover in modeset_gem_init, or set to the new value
on resume.
This means that to disable the primary plane 1 << drm_plane_index(primary)
needs to be used.
Afterwards because the crtc is no longer active it's forbidden to keep
plane_state->visible set, or a WARN_ON in
intel_plane_atomic_calc_changes triggers. There are other code points
that rely on accurate plane_state->visible too, so make sure the bool is
cleared.
The other planes are already disabled in intel_sanitize_crtc, so they
don't have to be handled here.

hold internal partial results. We can instead declare the temporary
variable inside the macro, so the caller need not provide it.
Some of the old code contained nested iterators that actually reused the
same 'temp' variable for both inner and outer instances. It's quite
surprising that this didn't introduce bugs! But it does show that the
value of 'temp' isn't required to persist during the iterated body.

Kabylake A0 is based on Skylake H0.
v2: Don't assume revid+7 and only load the one we are sure about.
v3: Rebase on top of latest changes.
v4: Accept cleaner solution from Jani with kbl_stepping_info
starting on H0 instead of put a hack on revid.

We were not checking the return value of drm_encoder_init() which can
fail. And if it fails then we will be working with an uninitialized
encoder.

Userspace can pass in an offset that it presumes the object is located
at. The kernel will then do its utmost to fit the object into that
location. The assumption is that userspace is handling its own object
locations (for example along with full-ppgtt) and that the kernel will
rarely have to make space for the user's requests.

v2: Fixed incorrect eviction found by Michal Winiarski - fix suggested by Chris
Wilson. Fixed incorrect error paths causing crash found by Michal Winiarski.
(Not published externally)
v3: Rebased because of trivial conflict in object_bind_to_vm. Fixed eviction
to allow eviction of soft-pinned objects when another soft-pinned object used
by a subsequent execbuffer overlaps reported by Michal Winiarski.
(Not published externally)
v4: Moved soft-pinned objects to the front of ordered_vmas so that they are
pinned first after an address conflict happens to avoid repeated conflicts in
rare cases (Suggested by Chris Wilson). Expanded comment on
drm_i915_gem_exec_object2.offset to cover this new API.
v5: Added I915_PARAM_HAS_EXEC_SOFTPIN parameter for detecting this capability
(Kristian). Added check for multiple pinnings on eviction (Akash). Made sure
buffers are not considered misplaced without the user specifying
EXEC_OBJECT_SUPPORTS_48B_ADDRESS. User must assume responsibility for any
addressing workarounds. Updated object2.offset field comment again to clarify
NO_RELOC case (Chris). checkpatch cleanup.
v6: Trivial rebase on latest drm-intel-nightly
v7: Catch attempts to pin above the max virtual address size and return
EINVAL (Tvrtko). Decouple EXEC_OBJECT_SUPPORTS_48B_ADDRESS and
EXEC_OBJECT_PINNED flags, user must pass both flags in any attempt to pin
something at an offset above 4GB (Chris, Daniel Vetter).

As described in the code comment, I couldn't set the minimum RPS
frequency on my BYT-M B0 to the minimum allowed as reported by Punit.
Fix this by clamping the minimum value to the first one that was
accepted on my machine.
Atm this issue doesn't cause any test failures, since in igt/pm_rps we
only check the cached version of the current frequency which is the same
what has been set. In the future we'll add checks for the actual
frequency too, and for that to pass this fix is necessary.

Currently we disable some parts of FDI setup after a failed link
training. But despite that we continue with the modeset as if everything
is fine. This results in tons of noise from the state checker, and
it means we're not following the proper modeset sequence for the rest of
crtc enabling, nor for crtc disabling.
Ideally we should abort the modeset and follow the proper disable
sequence to shut off everything we enabled so far, but that would
require a big rework of the modeset code. So instead just leave FDI
up and running in its untrained state, and log an error. This is
what we do on older platforms too.
