42a0d25649 drm/i915: Extract skl_watermark.c
Pull all the skl+ watermark code (and the dbuf/sagv/ipc code
since it's all sort of intertwined and I'm too lazy to think
of a finer grained split right now) into its own file from the
catch-all intel_pm.c.

Also sneak in the s/dev_priv/i915/ rename while at it.

Since we now have the bigjoiner_pipes bitmask the boolean
is redundant. Get rid of it.

f8a005eb89 drm/i915: Optimize icl+ universal plane programming
On icl+ all plane registers are armed by PLANE_SURF, so we can
move almost everything over into the update_noarm() hook.

The PLANE_CTL write has to stay in the icl_update_arm() hook though
as it still exhibits the somewhat annoying self-arming behaviour
when the plane transitioning from disabled to enabled.

We could either do a full split for skl+ vs. icl+, or we could try
some other kind of split where we'd eg. keep most things in the skl+
functions and call them from the icl+ functions. I think a full split
is probably the cleaner approach since we've anyway accumulated quite
a bit of icl+ specific things, so that is what I opted to do.

Also the masks we're using now don't even match the actual hardware

f84b336a2f drm/i915: Get rid of the 64bit PLANE_CC_VAL mmio
Let's just stick to 32bit mmio accesses so we can get rid
of the bare "uncore" reg access in display code. The register
are defined as 32bit in the spec anyway.

We could define a 64bit "de" variant I suppose, but doesn't
really make much sense just for this one case, and when we
start to use the DSB for this stuff we'd also need another
64bit variant for that. Just easier to do 32bit always.

While at it we can reorder stuff a bit so that we write the
registers in order of increasing offset (more or less).

0e959b4e99 drm/i915: Add PLANE_CUS_CTL restriction in max_width
PLANE_CUS_CTL has a restriction of 4096 width even though
PLANE_SIZE and scaler size registers supports max 5120.
Take care of this restriction in max_width.

Without this patch, when 5k content is sent on HDR plane
with NV12 content, FIFO underrun is seen and screen blanks
out.

v2: Addressed review comments from Ville. Added separate
functions for max_width - for HDR and SDR

v3: Addressed review comments from Ville. Changed names of

8ac80733cf drm/i915: Split update_plane() into update_noarm() + update_arm()
The amount of plane registers we have to write has been steadily
increasing, putting more pressure on the vblank evasion mechanism
and forcing us to increase its time budget. Let's try to take some
of the pressure off by splitting plane updates into two parts:
1) write all non-self arming plane registers, ie. the registers
   where the write actually does nothing until a separate arming
   register is also written which will cause the hardware to latch
   the new register values at the next start of vblank
2) write all self arming plane registers, ie. registers which always
   just latch at the next start of vblank, and registers which also
   arm other registers to do so

Here we just provide the mechanism, but don't actually implement
the split on any platform yet. so everything stays now in the _arm()
hooks. Subsequently we can move a whole bunch of stuff into the
_noarm() part, especially in more modern platforms where the number
of registers we have to write is also the greatest. On older
platforms this is less beneficial probably, but no real reason
to deviate from a common behaviour.

And let's sprinkle some TODOs around the areas that will need
adapting.

50faf7a194 drm/i915: Fix async flip with decryption and/or DPT
We're currently forgetting to set the PLANE_SURF_DECRYPT
flag in the async flip path. So if the hardware were to
latch that bit despite this being an async flip we'd start
scanning out garbage. And if it doesn't latch it then I
guess we'd just end up with a weird register value that
doesn't actually match the hardware state, which isn't
great for anyone staring at register dumps.

Similarly the async flip path also forgets to call
skl_surf_address() which means the DPT address space to
GGTT address space downshift is not being applied to
the offset. Which means we are pointing PLANE_SURF
at some random location in GGTT instead of the correct
DPT page.

So let's fix two birds with one stone and extract the
PLANE_SURF calculation from skl_program_plane() into
a small helper and use it in the async flip path as well.

e6d6f68943 drm/i915/adlp/fb: Remove restriction on CCS AUX plane strides
As opposed to other GEN12 platforms ADLP provides a way to program the
stride of CCS surfaces independently of the main surface stride (within
the corresponding limit of the preceding and succeeding power-of-two
values of the main surface stride). Using this HW feature we can remove
the POT stride restriction on CCS surfaces, making the ADLP CCS FB uAPI
(FB modifiers) identical to that of TGL.

The HW makes the CCS stride flexible programming possible by deriving
the stride from the value programmed to the PLANE_STRIDE register. After
that the HW rounds up this value to the next power-of-two value and uses
this for walking the pages of the main surface mapped to GTT/DPT.

To align with the above scheme, introduce a scanout_stride view
parameter which will be programmed to the PLANE_STRIDE register and use
the mapping_stride view param to store the POT aligned value of the
same. By requiring userspace to pass in FBs with a CCS stride that
aligns with the main surface stride (matching the requirement of all
GEN12 platforms), the scanout_stride will be the userspace main surface
stride and the mapping_stride will be the POT rounded value of the same.

10a657dd4c drm/i915/fb: Fold modifier CCS type/tiling attribute to plane caps
By using the modifier plane capability flags to encode the modifiers'
CCS type and tiling attributes, it becomes simpler to the check for
any of these capabilities when providing the list of supported
modifiers.

This also allows distinguishing modifiers on future platforms where
platforms with the same display version support different modifiers. An
example is DG2 and ADLP, both being D13, where DG2 supports only F and X
tiling, while ADLP supports only Y and X tiling. With the
INTEL_PLANE_CAP_TILING_* flags added in this patch we can provide
the correct modifiers for each platform.

v2:
- Define PLANE_HAS_* with macros instead of an enum. (Jani)
- Rename PLANE_HAS_*_ANY to PLANE_HAS_*_MASK. (Jani)
- Rename PLANE_HAS_* to INTEL_PLANE_CAP_*.
- Set the CCS_RC_CC cap only for DISPLAY_VER >= 12.
- Set the TILING_Y cap only for DISPLAY_VER < 13 || ADLP.
- Simplify the SKL plane cap display version checks and move them
  to a separate function.

- Get the modifiers calling intel_fb_get_modifiers() in i9xx_plane.c as
  well.
v3:
- s/.id/.modifier/ (Ville)
- Keep modifier_desc vs. plane_cap filter conditions consistent. (Ville)
- Drop redundant cursor plane check from skl_plane_has_rc_ccs(). (Ville)
- Use from, until display version fields in modifier_desc instead of a mask. (Jani)
- Unexport struct intel_modifier_desc, separate its decl and init. (Jani)
- Remove enum pipe, plane_id forward decls from intel_fb.h, which are
  not needed after v2.
v4:
- Reuse IS_DISPLAY_VER() instead of open-coding it. (Jani)
- Preserve the current modifier order exposed to user space. (Ville)
v5: Use }, { on one line to seperate the descriptor array elements. (Jani)

17dbbe7b25 drm/i915: Rename intel_load_plane_csc_black()
intel_load_plane_csc_black() is specific to icl+ so deserves
a name reflecting that fact. Also rename the variables to
standard form so I won't get confused reading the code.

v2: icl+ not glk+

63d7d05678 drm/i915: Remove the drm_dbg() from the vblank evade critical section
We are inside the vblank evade critical section here, racing
against the raster beam. There is no time to print debug
messages.

841f262e74 drm/i915: Fix up skl_program_plane() pxp stuff
There's lots of expensive stuff inserted between the PLANE_CTL
and  PLANE_SURF writes even though the comment before the PLANE_CTL
write says not to put stuff there. Move it all to a more apporiate
place.

There's also a weird PLANE_COLOR_CTL RMW in there. I guess because
force_black was computed way too late originally, but that is now
sorted.

f9a7b19c48 drm/i915: Move the pxp plane state computation
No real reason to have this pxp state computation in
intel_atomic_check_planes(). Just stuff it into skl_plane_check().

There was also some funny state copying being done from the
old plane state to the new plane state when the plane is anyway
disabled.

The one thing we presumably must remember to do is copy
over the decrypt state when assigning a Y plane for planar
YCbCr scanout, so that the Y plane's PLANE_SURF will get the
appropriate bit set. The force_black thing should not matter
as I'm pretty sure all that stuff is ignored for the Y plane.
I suppose this was the reason for the odd placement for the
state computation, but I see no reason to deviate from the
standard way of doing these things. This also guarantees
that we don't calculate things differently between the
linked UV and Y plane.

v2: Only do stuff for icl+ since 'force_black' depends
    on the plane CSC which is an icl+ feature
