Use Coccinelle to convert most of the usage of INTEL_GEN() and IS_GEN()
in the display code to use DISPLAY_VER() comparisons instead. The
following semantic patch was used:
@@ expression dev_priv, E; @@
- INTEL_GEN(dev_priv) == E
+ IS_DISPLAY_VER(dev_priv, E)
@@ expression dev_priv; @@
- INTEL_GEN(dev_priv)
+ DISPLAY_VER(dev_priv)
@@ expression dev_priv; expression E; @@
- IS_GEN(dev_priv, E)
+ IS_DISPLAY_VER(dev_priv, E)
@@
expression dev_priv;
expression from, until;
@@
- IS_GEN_RANGE(dev_priv, from, until)
+ IS_DISPLAY_RANGE(dev_priv, from, until)
There are still some display-related uses of INTEL_GEN() in intel_pm.c
(watermark code) and i915_irq.c. Those will be updated separately.
v2:
- Use new IS_DISPLAY_RANGE and IS_DISPLAY_VER helpers. (Jani)

commit 33267703df15 ("drm/i915/dsi: Enable software vblank counter")
claims to get the mode_flags from the crtc_state, but in fact does
not. Fix it to do it right.

For platforms/outputs without hardware frame counters we can't
call drm_crtc_accurate_vblank_count() when the vblank support is
disabled or we just get a WARN due to the crtc timings
(vblank->hwmode) being considered invalid. Note that until the
pipe in question has been enabled and drm_crtc_set_max_vblank_count()
has been called on it we would also take this path on platforms
which have a working frame counter. So getting the WARN is rather
likely on any platform unless you always boot with lots of displays
plugged in.
Also even on hardware with a working frame counter we may not be
able to read the actual frame counter register on disabled pipes
due the relevant power well being disabled. Ie. would just result
in the unclaimed reg spew.
So let's just avoid all this an directly report zero in case
the pipe is disabled.

On platforms/outputs without a working frame counter we rely
on the vblank code to cook up the frame counter from the timestamps.
That requires that vblank support is enabled. Thus we need to
move the pipe enable/disable tracepoints to the other side
of the drm_vblank_{on,off}() calls. There shouldn't really be
much happening between these old and new call sites so the
tracepoints should still provide reasonable data.
The alternative would be to give up on having the frame counter
values in the trace which would render the tracepoints more or
less pointless.
v2: Missed one case in intel_ddi_post_disable()
Drop the now useless i915_trace.h includes

We tend to use output_format!=RGB as a shorthand for YCbCr, but
this fails if we have a disabled crtc where output_format==INVALID.
We're now getting some fail from intel_color_check() when we have:
hw.enable==false
hw.ctm!=NULL
output_format==INVALID
Let's avoid that by throwing INTEL_OUTPUT_FORMAT_INVALID to the
dumpster, and thus everything defaults to RGB when the crtc
is disabled.
This does beg the deeper question of how much of the state
should we in fact be validating when hw/uapi.enable==false.
And should we even be doing the uapi->hw copy when
uapi.enable==false? So far I've not been able to come up with
satisfactory answers for myself, so I'm putting it off for the
moment.

Rework the plane init calls to do the gen test one level higher.
Rework some of the plane helpers so they can live in new file,
there is still some scope to clean up the plane/fb interactions
later.
v2: drop atomic code back, rename file to Ville suggestions,
add header file.
v3: move scaler bits back
v4: drop wrong new includes (Ville)
v5: integrate the ccs gen12 changes
v6: fix unrelated code movement (Ville)
