[Intel-gfx] [PATCH 00/11] drm/i915: Audio fastset, and some fixes

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Implement audio fastset. Probably mosy useful in avoiding
some fastboot blinks, runtime audio fastset is less likely
to be a typical use case.

Also try to fix up a mess with pre_plane_update() vs.
already disabled pipe.

Ville Syrjälä (11):
  drm/i915: Check pipe active state in
    {planes,vrr}_{enabling,disabling}()
  drm/i915: Call intel_pre_plane_updates() also for pipes getting
    enabled
  drm/i915: Polish some RMWs
  drm/i915: Push audio enable/disable further out
  drm/i915: Wrap g4x+ DP/HDMI audio enable/disable
  drm/i915: Split g4x+ DP audio presence detect from port enable
  drm/i915: Split g4x+ HDMI audio presence detect from port enable
  drm/i915: Convert audio enable/disable into encoder vfuncs
  drm/i915: Hoist the encoder->audio_{enable,disable}() calls higher up
  drm/i915: Push audio_{enable,disable}() to the pre/post pane update
    stage
  drm/i915: Implement audio fastset

[Intel-gfx] [PATCH 01/11] drm/i915: Check pipe active state in {planes, vrr}_{enabling, disabling}()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

{planes,vrr}_{enabling,disabling}() are supposed to indicate
whether the specific hardware feature is supposed to be enabling
or disabling. That can only makes sense if the pipe is active
overall. So check for that before we go poking at the hardware.

I think we're semi-safe currently on due to:
- intel_pre_plane_update() doesn't get called when the pipe
  was not-active prior to the commit, but this is actually a bug.
  This saves vrr_disabling(), and vrr_enabling() is called from
  deeper down where we have already checked hw.active.
- active_planes mirrors the crtc's hw.active

[Intel-gfx] [PATCH 02/11] drm/i915: Call intel_pre_plane_updates() also for pipes getting enabled

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We used to call intel_pre_plane_updates() for any pipe going through
a modeset whether the pipe was previously enabled or not. This in
fact needed to apply all the necessary clock gating workarounds/etc.
Restore the correct behaviour.

[Intel-gfx] [PATCH 03/11] drm/i915: Polish some RMWs

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Doing the if-else around RMWs is kinda silly. Just set/clear the
apporiate bits with a single RMW.

Also unify the coding style a bit icl_wa_cursorclkgating() while at it.

[Intel-gfx] [PATCH 04/11] drm/i915: Push audio enable/disable further out

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Push the audio enable/disable to be the last/first thing
respectively that is done in the encoder enable/disable hooks.
The goal is to move it further out of these encoder hooks entirely.

[Intel-gfx] [PATCH 05/11] drm/i915: Wrap g4x+ DP/HDMI audio enable/disable

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Put a wrapper around the intel_audio_codec_{enable,disable}()
calls in the g4x+ DP/HDMI code. We shall move the presence
detect enable/disable into the wrappers later.

[Intel-gfx] [PATCH 06/11] drm/i915: Split g4x+ DP audio presence detect from port enable

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Follow the hsw+ approach toggle the audio presence detect
when we set up the ELD, instead of doing it when turning the
port on/off.

This will facilitate audio enable/disable to happen during
fastsets instead of requiring a full modeset.

[Intel-gfx] [PATCH 08/11] drm/i915: Convert audio enable/disable into encoder vfuncs

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Add encoder vfuncs for audio enable/disable. This will enable
audio to be enable/disabe during fastsets. An encoder hook
is necessary as on pre-hsw platforms different encoder types
implement audio in different ways.

[Intel-gfx] [PATCH 10/11] drm/i915: Push audio_{enable, disable}() to the pre/post pane update stage

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Relocate the audio enable/disable from the full modeset hooks into
the common pre/post plane update stage of the commit. Audio fastset
is within easy reach now.

[Intel-gfx] [PATCH 11/11] drm/i915: Implement audio fastset

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

There's no real why we'd need a full modeset for audio changes.
So let's allow audio to be toggled during fastset. In case the
ELD changes while has_audio isn't changing state we force both
audio disable and enable so the new ELD gets propagated to the
audio driver.

Makes me wonder if these check should've been added to the
is_enabling/is_disabling macros instead. *shrug*

I had it like that originally, but then I decided against it for
some reason that I seem to have forgotten already...

I *think* I was planning to use is_{enabling,disabling}() in some
other context where that check doesn't make sense. But I think in
the end I convinced myself that I can't actually do that due to
other reasons. So yeah, putting these into is_{enabling,disabling}()
would probably make sense. But I think I'll have to mull it over a
bit more.

After further thought it won't work because we do stuff like
	is_enabling(...) || other_conditions

So we need the crtc_state->hw.active check to catch both sides
of the OR.
