They have been unused since 2010, after the code for
intel_tv_save/restore was removed in the below commit:

commit 6443170f
Author: Eric Anholt <eric@anholt.net>
Date:   Fri Apr 2 15:24:27 2010 -0700

    drm/i915: Remove dead KMS encoder save/restore code.

    This was brought over from UMS, and used for a while until we decided
    that drm_helper_resume_force_mode was easier and more reliable, since
    it didn't require duplicating all the code deleted here.  We just
    forgot to delete all that junk for a while.

Similar to commit 8490ae20 ("drm/i915: Suppress busy status for
engines if wedged") we also want to report intel_engine_is_idle() as
true as well as the main intel_engines_are_idle(), as we now check that
the engines are idle when overwriting the HWS page. This is not true
whilst we are setting the device as wedged, at least according to our
bookkeeping, so we have to lie to ourselves!

In link training fallback, we're trying to find a rate that we know is
in a sorted array of common link rates. We don't need to limit the array
using the max rate. For test request, the DP CTS doesn't say we should
limit the rate based on earlier fallback. This lets us get rid of
intel_dp_link_rate_index() and use intel_dp_rate_index() instead.

Now that source rates are static and sink rates are updated whenever
DPCD is updated, we can do and cache the intersection of them whenever
sink rates are updated. This reduces code complexity, as we don't have
to keep calling the functions to intersect. We also get rid of several
common rates arrays on stack.

Limiting the common rates by a max link rate can be done by picking the
first N elements of the cached common rates.

If we needed to do something different for the init functions, we could
always look at the engine instance to make the distinction. But, in any

With this, the init functions depends excusively on the engine class

While we do hold the forcewake for legacy ringbuffer initialisation, we

Since the sandybridge_pcode_read() may be called from
skl_pcode_request() inside an atomic context (with preempt disabled), we
should avoid hitting any sleeping paths. Currently is being called with
a 500ms timeout, irrespective of being inside an atomic context or not.
This is reduced down to 500us to play nice with the atomic context, and
that appears to be sufficient to keep BAT happy (we have a DRM_ERROR
should it timeout), i.e. we do not see any 500us pcode timeouts for
normal use. So leave it as a pure spin without having to introduce new
code paths to separate atomic/normal contexts.

These params are passed by value, const qualifiers are ignored any way.
While around, unify timeout_ms type from long to int.

The void *data passed to debugfs callbacks is actually the
drm_i915_private pointer, so use it thusly and avoid the to_i915(dev)
indirection.
