We use 3 different names to refer to the same render ring INSTDONE
register. This can be confusing when comparing two parts of the code
accessing the register via different names. Although the GEN4 version's
layout is different, we treat it the same way as the GEN7+ version, in
that we simply read it out during error capture. So remove the
duplicates and leave a comment about the GEN4 difference.

Note that there is also a GEN2 version of this register, but that's on a
different address so not handled in this patch.

There are some allocations that must be only referenced by 32-bit
offsets. To limit the chances of having the first 4GB already full,
objects not requiring this workaround use DRM_MM_SEARCH_BELOW/
DRM_MM_CREATE_TOP flags

In specific, any resource used with flat/heapless (0x00000000-0xfffff000)
General State Heap (GSH) or Instruction State Heap (ISH) must be in a
32-bit range, because the General State Offset and Instruction State
Offset are limited to 32-bits.

Objects must have EXEC_OBJECT_SUPPORTS_48B_ADDRESS flag to indicate if
they can be allocated above the 32-bit address range. To limit the
chances of having the first 4GB already full, objects will use
DRM_MM_SEARCH_BELOW + DRM_MM_CREATE_TOP flags when possible.

Calculate pipe watermarks during atomic calculation phase, based on the
contents of the atomic transaction's state structure.  We still program
the watermarks at the same time we did before, but the computation now
happens much earlier.

While this patch isn't too exciting by itself, it paves the way for
future patches.  The eventual goal (which will be realized in future
patches in this series) is to calculate multiple sets up watermark
values up front, and then program them at different times (pre- vs
post-vblank) on the platforms that need a two-step watermark update.

While we're at it, s/intel_compute_pipe_wm/ilk_compute_pipe_wm/ since
this function only applies to ILK-style watermarks and we have a
completely different function for SKL-style watermarks.

Note that the original code had a memcmp() in ilk_update_wm() to avoid
calling ilk_program_watermarks() if the watermarks hadn't changed.  This
memcmp vanishes here, which means we may do some unnecessary result
generation and merging in cases where watermarks didn't change, but the
lower-level function ilk_write_wm_values already makes sure that we
don't actually try to program the watermark registers again.

v2: Squash a few commits from the original series together; no longer
    leave pre-calculated wm's in a separate temporary structure since
    it's easier to follow the logic if we just cut over to using the
    pre-calculated values directly.

v3:
 - Pass intel_crtc instead of drm_crtc to .compute_pipe_wm() entrypoint
   and use intel_atomic_get_crtc_state() to avoid need for extra
   casting.  (Ander)

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.

Let the compiler figure out what I915_MAX_PLANES is from 'enum plane' so
that we don't need a separate #define.

While we're at it, add the cursor plane to the enum.  This will cause
I915_MAX_PLANES to now include the cursor plane in its count (it didn't
previously).   This change is safe since we currently only use this
value in array declarations (never in the actual code logic); we just
wind up allocating slightly more memory than we need to.  A followup
patch will cause various parts of the code to start using the extra
array element where appropriate.

(This patch probably should have been squashed with the followup patch,
but I couldn't figure out how to get Coccinelle to modify enum
declarations...)

            drm/i915: Don't forget to mark crtc as inactive after disable

we added extra watermark updates to all of the .crtc_disable()
entrypoints to avoid problems problems with system resume on SKL.  Those
disable entrypoints are currently called in just two places in the
driver: intel_atomic_commit (i.e., during a modeset) and
intel_crtc_disable_noatomic (which is called during hardware readout).
It seems that this extra watermark recalculation should only be
important in the latter case (which happens during a resume operation);
the former case should always have appropriate watermark programming
happening at other points in the modeset sequence.

Let's move the watermark update out of the .crtc_disable() entrypoints
and place it directly in intel_crtc_disable_noatomic() so that it only
happens on S3 resume and not during a regular modeset (since the
existing watermark handling should properly update watermarks during
normal atomic commits).

Previously we've relied on having basically one backlight and one

support on VLV/CHV platforms with MIPI DSI. In the foreseeable future
we'll have at least DPCD based backlight control on eDP and DCS command
based backlight control on MIPI DSI. Backlight is becoming more and more
connector specific, so reflect this fact by making the backlight control
hooks connector specific.

This enables further work to reuse generic backlight code in
intel_panel.c while adding more specific backlight code accessed via the
hooks.
