Ville Syrjälä 72618ebfde drm/i915: Use fb modifiers for display tiling decisions
Soon the fence tiling mode may not always match the fb modifier
even for X tiled buffers. So let's use the fb modifier
consistently for all display tiling decisions.

Ville Syrjälä 2949056c86 drm/i915: Pass around plane_state instead of fb+rotation
intel_compute_tile_offset() and intel_add_fb_offsets() get passed the fb
and the rotation. As both of those come from the plane state we can just
pass that in instead.

For extra consitency pass the plane state to intel_fb_xy_to_linear() as
well even though it only really needs the fb.

Ville Syrjälä ef78ec9423 drm/i915: Don't pass pitch to intel_compute_page_offset()
intel_compute_page_offset() can dig up the correct pitch from the fb
itself, no need for the caller to pass it in.

A bit of extra care is needed for the lower level
_intel_compute_page_offset() since that one gets called before the
rotated pitch under intel_fb is populated. Note that we don't actually
call it with anything but DRM_ROTATE_0 there so we wouldn't actually
look up the rotated pitch there, but still, leave the pitch as something
the caller has to pass to _intel_compute_page_offset() as an
indicator that something is a bit special.

This leaves 'stride_div' in the skl plane update hooks as a mostly useless
variable so just get rid of it.

v2: Add a note why stride_div got nuked
v3: Extract intel_fb_pitch() since it can be useful later

Ville Syrjälä 6687c9062c drm/i915: Rewrite fb rotation GTT handling
Redo the fb rotation handling in order to:
- eliminate the NV12 special casing
- handle fb->offsets[] properly
- make the rotation handling easier for the plane code

To achieve these goals we reduce intel_rotation_info to only contain
(for each plane) the rotated view width,height,stride in tile units,
and the page offset into the object where the plane starts. Each plane
is handled exactly the same way, no special casing for NV12 or other
formats. We then store the computed rotation_info under
intel_framebuffer so that we don't have to recompute it again.

To handle fb->offsets[] we treat them as a linear offsets and convert
them to x/y offsets from the start of the relevant GTT mapping (either
normal or rotated). We store the x/y offsets under intel_framebuffer,
and for some extra convenience we also store the rotated pitch (ie.
tile aligned plane height). So for each plane we have the normal
x/y offsets, rotated x/y offsets, and the rotated pitch. The normal
pitch is available already in fb->pitches[].

While we're gathering up all that extra information, we can also easily
compute the storage requirements for the framebuffer, so that we can
check that the object is big enough to hold it.

When it comes time to deal with the plane source coordinates, we first
rotate the clipped src coordinates to match the relevant GTT view
orientation, then add to them the fb x/y offsets. Next we compute
the aligned surface page offset, and as a result we're left with some
residual x/y offsets. Finally, if required by the hardware, we convert
the remaining x/y offsets into a linear offset.

For gen2/3 we simply skip computing the final page offset, and just
convert the src+fb x/y offsets directly into a linear offset since
that's what the hardware wants.

After this all platforms, incluing SKL+, compute these things in exactly
the same way (excluding alignemnt differences).

v2: Use BIT(DRM_ROTATE_270) instead of ROTATE_270 when rotating
    plane src coordinates
    Drop some spurious changes that got left behind during
    development
v3: Split out more changes to prep patches (Daniel)
    s/intel_fb->plane[].foo.bar/intel_fb->foo[].bar/ for brevity
    Rename intel_surf_gtt_offset to intel_fb_gtt_offset
    Kill the pointless 'plane' parameter from intel_fb_gtt_offset()
v4: Fix alignment vs. alignment-1 when calling
    _intel_compute_tile_offset() from intel_fill_fb_info()
    Pass the pitch in tiles in
    stad of pixels to intel_adjust_tile_offset() from intel_fill_fb_info()
    Pass the full width/height of the rotated area to
    drm_rect_rotate() for clarity
    Use u32 for more offsets
v5: Preserve the upper_32_bits()/lower_32_bits() handling for the
    fb ggtt offset (Sivakumar)
v6: Rebase due to drm_plane_state src/dst rects

Daniel Vetter 618100f8a8 Add get_eld audio component for i915/HD-audio
Here are the patchset to add get_eld op to audio component for
 communicating more directly between i915 and HD-audio.
 
 Currently, the HDMI/DP audio status and ELD are notified and obtained
 via the hardware-level communication over HD-audio unsolicited event
 and verbs although the graphics driver holds the exactly same
 information.  As we already have a notification via audio component,
 this is another step forward; namely, the audio driver may fetch
 directly the audio status and ELD via the new component op.
 
 The commits are based on Dave's latest drm-next branch.

Ville Syrjälä b0b3b79511 drm: Pass 'name' to drm_universal_plane_init()
Done with coccinelle for the most part. It choked on
msm/mdp/mdp5/mdp5_plane.c like so:
"BAD:!!!!!  enum drm_plane_type type;"
No idea how to deal with that, so I just fixed that up
by hand.

Also it thinks '...' is part of the semantic patch, so I put an
'int DOTDOTDOT' placeholder in its place and got rid of it with
sed afterwards.

I didn't convert drm_plane_init() since passing the varargs through
would mean either cpp macros or va_list, and I figured we don't
care about these legacy functions enough to warrant the extra pain.

Wayne Boyer 666a45379e drm/i915: Separate cherryview from valleyview
The cherryview device shares many characteristics with the valleyview
device.  When support was added to the driver for cherryview, the
corresponding device info structure included .is_valleyview = 1.
This is not correct and leads to some confusion.

This patch changes .is_valleyview to .is_cherryview in the cherryview
device info structure and simplifies the IS_CHERRYVIEW macro.
Then where appropriate, instances of IS_VALLEYVIEW are replaced with
IS_VALLEYVIEW || IS_CHERRYVIEW or equivalent.

v2: Use IS_VALLEYVIEW || IS_CHERRYVIEW instead of defining a new macro.
    Also add followup patches to fix issues discovered during the first
    review. (Ville)
v3: Fix some style issues and one gen check. Remove CRT related changes
    as CRT is not supported on CHV. (Imre, Ville)
v4: Make a few more optimizations. (Ville)

VMA offsets are 64 bits. Plane surface offsets are in ggtt and
the hardware register to set this is thus 32 bits. Be explicit

This will make sparse happy by not creating 32bit pointers out

Matt Roper 791a32be6e drm/i915: Drop intel_update_sprite_watermarks
The only platform that still has an update_sprite_wm entrypoint is SKL;
on SKL, intel_update_sprite_watermarks just updates intel_plane->wm and
then performs a regular watermark update.  However intel_plane->wm is
only used to update a couple fields in intel_wm_config, and those fields
are never used by the SKL code, so on SKL an update_sprite_wm is
effectively identical to an update_wm call.  Since we're already
ensuring that the regular intel_update_wm is called any time we'd try to
call intel_update_sprite_watermarks, the whole call is redundant and can
be dropped.

and the primary plane the same.  For the primary plane we do enable
the pipe gamma on the plane so do the same for the non-primary planes.

displayed on the primary plane and something displayed on a sprite
plane when the ARGB8888 format is used.

This is a squash of the following commits:

Revert "drm/i915: Drop intel_update_sprite_watermarks"
This reverts commit 47c99438b5.

Revert "drm/i915/ivb: Move WaCxSRDisabledForSpriteScaling w/a to atomic check"

Revert "drm/i915/skl: Eliminate usage of pipe_wm_parameters from SKL-style WM (v3)"
This reverts commit 3a05f5e2e7.

With these reverts, SKL finally stops failing every single FBC test
with FIFO underrun error messages. After some brief testing, it also
seems that this commit prevents the machine from completely freezing
when we run igt/kms_fbc_crc (see fd.o #92355).

In order to get decnet memory self refresh residency on VLV, flip it
over to the new CHV way of doing things. VLV doesn't do PM5 or DDR DVFS
so it's a bit simpler.

I'm not sure the currently memory latency used for CHV is really
appropriate for VLV. Some further testing will probably be needed to
figure that out.

Maarten Lankhorst a539205a16 drm/i915: atomic plane updates in a nutshell
Now that all planes are added during a modeset we can use the
calculated changes before disabling a plane, and then either commit
or force disable a plane before disabling the crtc.

The code is shared with atomic_begin/flush, except watermark updating
and vblank evasion are not used.

This is needed for proper atomic suspend/resume support.

Ville Syrjälä 4e9a86b6bd drm/i915: Actually respect DSPSURF alignment restrictions
Currently intel_gen4_compute_page_offset() simply picks the closest
page boundary below the linear offset. That however may not be suitably
aligned to satisfy any hardware specific restrictions. So let's make
sure the page boundary we choose is properly aligned.

Also to play it a bit safer lets split the remaining linear offset into
x and y values instead of just x. This should make no difference for
most platforms since we convert the x and y offsets back into a linear
offset before feeding them to the hardware. HSW+ are different however
and use x and y offsets even with linear buffers, so they might have
trouble if either the x or y get too big.

There is a mplayer video failure reported with xv.
This is because there is a request to do both plane scaling
and colorkey. Because skl hw doesn't support plane scaling

behavior.

To make xv operate, this patch allows colorkey continue to work
without using scaler. Then behavior would be similar to platforms
without plane scaler support.

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.

Ville Syrjälä bdd7554d56 drm/i915: Kill intel_plane->obj
intel_plane->obj is not used anymore so kill it. Also don't pass both
the fb and obj to the sprite .update_plane() hook, as just passing the fb
is enough.

Tvrtko Ursulin 0fda65680e drm/i915/skl: Update watermarks for Y tiling
Display watermarks need different programming for different tiling
modes.

Set the relevant flag so this happens during the plane commit and
add relevant data into a structure made available to the watermark
computation code.

v2: Pass in tiling info to sprite plane updates as well.
v3: Rebased for plane handling changes.
v4: Handle fb == NULL when plane is disabled.
v5: Refactored for addfb2 interface.
v6: Refactored for fb modifier changes.
v7: Updated for atomic commit by only updating watermarks when tiling changes.
v8: BSpec watermark calculation updates.
v9: Restrict scope of y_tile_minimum variable. (Damien Lespiau)
v10: Get fb from plane state otherwise we are working on old state.

Paulo Zanoni e35fef211b drm/i915: change dev_priv->fbc.plane to dev_priv->fbc.crtc
Since the mapping from CRTCs to planes is fixed, looking at the CRTC
is essentially the same as looking at the plane. Also, the next
patches wil start using the frontbuffer_bits macros, and they take the
pipe as the parameter instead of the plane, and this could differ on
gens 2 and 3.

Another nice thing is that we don't risk accidentally initializing
things to PLANE_A if we don't set the value before it is used for the
first time. But this shouldn't be a problem with the current code.

V2: Rebase.

Matt Roper 65a3fea0a6 drm/i915: Consolidate plane handler vtables
All of the previous refactoring/consolidation of plane code has resulted
in intel_primary_plane_funcs, intel_cursor_plane_funcs, and
intel_sprite_plane_funcs being identical.  Replace all of these with a
single 'intel_plane_funcs' vtable for simplicity.

Matt Roper 8e7d688b7a drm/i915: Move rotation from intel_plane to drm_plane_state
Runtime state that can be manipulated via properties should now go in
intel_plane_state/drm_plane_state so that it can be tracked as part of
an atomic transaction.

We add a new 'intel_create_plane_state' function so that the proper
initial value for this property (and future properties) doesn't have to
be repeated at each plane initialization site.

v2:
 - Stick rotation in common drm_plane_state rather than
   intel_plane_state. (Daniel)
 - Add intel_create_plane_state() to consolidate the places where we
   have to set initial state values.  (Ander)
