Chandra Konduru 663a36407a drm/i915: Preserve scaler state when clearing crtc_state
crtc_state is cleared during mode set which wipes out complete
scaler state too. This is causing issues. To fix, ensure scaler
state is preserved because it contains not only crtc
scaler usage, but also planes using scalers on this crtc.

Ander Conselvan de Oliveira 9bdbd0b911 drm/i915: Allocate connector state together with the connectors
Connector states were being allocated in intel_setup_outputs() in loop
over all connectors. That meant hot-added connectors would have a NULL
state. Since the change to use a struct drm_atomic_state for the legacy
modeset, connector states are necessary for the i915 driver to function
properly, so that would lead to oopses.

Matt Roper 70a101f863 drm/i915: Switch to full atomic helpers for plane updates/disable, take two
Switch from our plane update/disable entrypoints to use the full atomic
helpers (which generate a top-level atomic transaction) rather than the
transitional helpers (which only create/manipulate orphaned plane states
independent of a top-level transaction).  Various upcoming work (SKL
scalers, atomic watermarks, etc.) requires a full atomic transaction to
behave properly/cleanly.

Last time we tried this, we had to back out the change because we still
call the drm_plane vfuncs directly from within our legacy modesetting
code.  This potentially results in nested atomic transactions, locking
collisions, and other failures.  To avoid that problem again, we
sidestep the issue by calling the transitional helpers directly (rather
than through a vfunc) when we're nested inside of other legacy
modesetting code.  However this does allow legacy SetPlane() ioctl's to
process an entire drm_atomic_state transaction, which is important for
upcoming patches.

Chris Wilson 6ad790c0f5 drm/i915: Boost GPU frequency if we detect outstanding pageflips
If we hit a vblank and see that have a pageflip queue but not yet
processed, ensure that the GPU is running at maximum in order to clear
the backlog. Pageflips are only queued for the following vblank, if we
miss it, there will be a visible stutter. Boosting the GPU frequency
doesn't prevent us from missing the target vblank, but it should help
the subsequent frames hitting theirs.

flip after processing the completion events, and avoid spurious boosts.

Chris Wilson cf5d8a46a0 drm/i915: Fix the flip synchronisation to consider mmioflips
Currently we emit semaphore synchronisation as if we were going to flip
using the target CS engine, but we then change our minds and do the flip
using the CPU. Consequently we write instructions to the ring but never
use them - even to the point of filling that ring up entirely and never
submitting a request.

The wrinkle in the ointment is that we have to tell a white lie to
pin-to-display for it to skip the synchronisation for mmioflips as we
will create a task specifically for that slow synchronisation. An oddity
of note is the discrepancy in requests that we tell to pin-display to
serialise to and that we then eventually wait upon. This is due to a
limitation in the i915_gem_object_sync() routine that will be lifted
later.

The best_encoder field of connector_state wasn't properly set when a
connector was being disabled, leading to an incosistent atomic state.

For now, this doesn't cause anything to blow up, because everywhere
we're using connector_state->best_encoder there is a check for
connector_state->crtc which is properly initialized. I reached the issue
while testing some patches I haven't sent out yet, that remove the usage
of intel_connector->new_encoder from check_digital_port_conflicts(). In
that case, it would be possible to trigger the converted version of the
WARN in that function.

Joonas Lahtinen 9abc464854 drm/i915: Compare GGTT view structs instead of types
To allow for views where the view type is not defined by the view type only,
like it is in stereo or rotated 90 degree view, change the semantic to require
the whole view structure for comparison when we match a GGTT view.

This allows including parameters like offset to be included in the view which
is useful for eg. partial views.

v3:
- Rely on ggtt_view type being 0 for non-GGTT vma's, which equals to
  I915_GGTT_VIEW_NORMAL. (Daniel Vetter)
- Do not use potentially slower comparison when we only want to know if
  something is or is not a normal view.
- Rebase on top of rotated view patches. Add rotated view singleton.
- If one view is missing in comparison they're equal only if both are missing.

v4:
- Use comparison helper in obj_to_ggtt_view too. (Tvrtko Ursulin)
- Do WARN_ON if one view is NULL. (Tvrtko Ursulin)

    drm/i915: Fix modeset state confusion in the load detect code

But this time around it was the initial fb code that forgot to update
the plane->crtc pointer. Otherwise it's the exact same bug, with the
exact same restrains (any set_config call/ioctl that doesn't disable
the pipe papers over the bug for free, so fairly hard to hit in normal
testing). So if you want the full explanation just go read that one
over there - it's rather long ...

Rodrigo Vivi ab585dea12 drm/i915: kill i915.powersave
This flag was being mostly used as a meta flag in some
cases and not covering other cases.

One of the risks is that it was masking some frontbuffer
trackings without disabling PSR.

So, better to kill this at once and avoid umbrella parameters.

Tvrtko Ursulin 50470bb011 drm/i915/skl: Support secondary (rotated) frame buffer mapping
90/270 rotated scanout needs a rotated GTT view of the framebuffer.

This is put in a separate VMA with a dedicated ggtt view and wired such that
it is created when a framebuffer is pinned to a 90/270 rotated plane.

Rotation is only possible with Yb/Yf buffers and error is propagated to
user space in case of a mismatch.

Special rotated page view is constructed at the VMA creation time by
borrowing the DMA addresses from obj->pages.

v2:
    * Do not bother with pages for rotated sg list, just populate the DMA
      addresses. (Daniel Vetter)
    * Checkpatch cleanup.

v3:
    * Rebased on top of new plane handling (create rotated mapping when
      setting the rotation property).
    * Unpin rotated VMA on unpinning from display plane.
    * Simplify rotation check using bitwise AND. (Chris Wilson)

v4:
    * Fix unpinning of optional rotated mapping so it is really considered
      to be optional.

v5:
   * Rebased for fb modifier changes.
   * Rebased for atomic commit.
   * Only pin needed view for display. (Ville Syrjälä, Daniel Vetter)

v6:
   * Rebased after preparatory work has been extracted out. (Daniel Vetter)

v7:
   * Slightly simplified tiling geometry calculation.
   * Moved rotated GGTT view implementation into i915_gem_gtt.c (Daniel Vetter)

v8:
   * Do not use i915_gem_obj_size to get object size since that actually
     returns the size of an VMA which may not exist.
   * Rebased for ggtt view changes.

v9:
   * Rebased after code review changes on the preceding patches.
   * Tidy function definitions. (Joonas Lahtinen)
