[RESEND PATCH 1/5] drm/i915/backlight: Restore backlight on resume, v2.

[Maarten Lankhorst]

Restore our saved values for backlight. This way even with fastset on
S4 resume we will correctly restore the backlight to the active values.

Changes since v1:
- Call enable_backlight() when backlight.level is set. On suspend
  backlight.enabled is always cleared, this makes it not a good
  indicator. Also check for crtc->state->active.

[RESEND PATCH 2/5] drm/i915/backlight: Fix backlight takeover on LPT, v2.

[Maarten Lankhorst]

On lynxpoint the bios sometimes sets up the backlight using the CPU
display, but the driver expects using the PWM PCH override register.

Read the value from the CPU register, then convert it to the other
units by converting from the old duty cycle, to freq, to the new units.

This value is then programmed in the override register, after which
we set the override and disable the CPU display control. This allows
us to switch the source without flickering, and make the backlight
controls work in the driver.

Changes since v1:
- Read BLC_PWM_CPU_CTL2 to cpu_ctl2.
- Clean up cpu_mode if slightly.
- Always disable BLM_PWM_ENABLE in cpu_ctl2.

[HACK for CI] drm/i915: Update crtc scaler settings when update_pipe is set

[Maarten Lankhorst]

From: Hans de Goede <hdegoede@redhat.com>

When the pipe_config's update_pipe flag is set we may need to update the
panel fitting settings. On GEN9+ this means we need to update the crtc's
scaler settings.

This fixes the following WARN_ON, during i915 loading on an Asrock
B150M Pro4S/D3 board with an i5-6500 CPU / graphics:

[drm:pipe_config_err [i915]] *ERROR* mismatch in pch_pfit.enabled
 (expected no, found yes)
pipe state doesn't match!
WARNING: CPU: 3 PID: 305 at drivers/gpu/drm/i915/intel_display.c:12084

With line 12084 being the I915_STATE_WARN call inside the
"if (!intel_pipe_config_compare())" block in verify_crtc_state().

On this board with 2 1920x1080 monitors connected over HDMI the GOP
initializes both monitors at 1920x1080 and despite no scaling being
necessary configures a scaler for one of them.

When booting with fastboot=1 on the initial modeset needs_modeset will
be false while update_pipe is true. Since we were not calling
skl_update_scaler_crtc() in this case we would leave the scaler enabled
causing this error.

If the CPU register is driving the PCH PWM, I think you're good with
using val = pch_get_backlight(connector) directly. In that case, the
modulation frequency should be set in the PCH register anyway, and it
should be all right. The increments and reference clocks and everything
should be the same. So the duty cycle should be the same.

The CPU register modulation frequency stuff should only be used for
driving the backlight in the utility pin. That's a possibility we should
maybe check, but if this patch fixes anything, that's not the case
here. It's a physically different pin, and we only support that on
BXT. IIRC I've been told nobody uses that on HSW/LPT, and I don't recall
any relevant bug reports either.

Using the utility pin would involve:

* Setting the utility pin mode to PWM, and enabling it in UTIL_PIN_CTL
  (0x48400).

* Setting the PWM pin selects in BLC_MISC_CTL (0x48360).

* Setting the modulation frequency in BLC_PWM_CPU_CTL (0x48254) *or* in
  HSW_BLC_PWM2_CTL (0x48354) depending on BLC_MISC_CTL.

Perhaps we should add WARN_ON()s on util pin pwm mode and non-zero blc
misc, but that's another patch.

TL;DR make that:

	if (cpu_mode)
		val = pch_get_backlight(connector);
	else
		val = lpt_get_backlight(connector);

After the simplicication above, perhaps add a debug log here instead
about switching to PCH override.

Please move that within the cpu_mode block above. I want to minimize the
impact on !cpu_mode.

[RESEND PATCH 3/5] drm/i915: Enable fastset for non-boot modesets.

[Maarten Lankhorst]

Now that our state comparison functions are pretty complete, we should
enable fastset by default when a modeset can be avoided. Even if we're
not completely certain about the inherited state, we can be certain
after the first modeset that our sw state matches the hw state.

The patch looks good to me, but we must make sure this passes CI
first, I suggest you test this without the last patch in the series
which unconditionally enables fastset.

Also see Daniel's remarks to my resend of your earlier version of
this patch:

https://www.spinics.net/lists/intel-gfx/msg184622.html

[PATCH 4/5] drm/i915: Make HW readout mark CRTC scaler as in use.

[Maarten Lankhorst]

This way we don't accidentally double allocate it and hopefully disable
it during fastset. I noticed this when I wrote a patch to sanity check
all of the scaler state.

[RESEND PATCH 5/5] drm/i915: Re-enable fastset by default

[Maarten Lankhorst]

Now that we've solved the backlight issue, I think it's time to enable
this again by default. We've enabled it in the past, but backlight
issues prevented us from enabling it by default.

Our hardware readout is pretty complete, and with all of the connector
state moved to atomic I'm hoping we finally have enough capability to
re-enable fastset by default.

Re: [RESEND PATCH 1/5] drm/i915/backlight: Restore backlight on resume, v2.

I think this is a non-trivial commit that requires more explanation in
the commit message and comments.

What does this do for non-fastset resume? It seems to me this
enables/disables backlight twice in that case.

This doesn't take panel power sequencing into account at all. You can't
just go ahead and enable the PWM with no consideration of how that is
fed to the panel. That in turn is encoder code, so I'm not sure how that
could be bolted on here.

So I'm afraid I'm not convinced this will work.

One more detail in-line below.

panel->backlight.level is not necessarily 0-based, it's between
panel->backlight.{min,max}.

Neither, I've seen a very nice encoder update_pipe hook for fastset.

I think using this for S4 resume would solve the issue.
