[PATCH 00/15] drm/i915: refactor display funcs, add display irq hooks

[Jani Nikula]

I was going to add display irq hooks first, but decided the organization
of the existing hooks under display->funcs is a bit weird. Spread them
out by function first. And then add hooks for display irq calls.

The end goal is to reduce the number of functions exposed from display
to i915 and xe core.

Jani Nikula (15):
  drm/i915/display: move audio funcs under audio sub-struct
  drm/i915/display: move color funcs under color sub-struct

  drm/i915/irq: move VLV/CHV LPE irq handler call after irq acks
  drm/i915/irq: constify pipe stats parameters
  drm/i915/irq: add display irq funcs, start with
    intel_display_irq_reset()
  drm/i915/irq: add intel_display_irq_postinstall() to irq funcs
  drm/i915/irq: add intel_display_irq_ack() to irq funcs

[PATCH 01/15] drm/i915/display: move audio funcs under audio sub-struct

[Jani Nikula]

Move audio related functions under audio sub-struct of struct
intel_display.

The funcs sub-struct of struct intel_display seems unnecessary. Instead
of display->funcs.FEATURE, prefer display->FEATURE.funcs.

[PATCH 05/15] drm/i915/display: move hotplug irq funcs under hotplug sub-struct

[Jani Nikula]

Move hotplug irq related functions under hotplug sub-struct of struct
intel_display.

The funcs sub-struct of struct intel_display seems unnecessary. Instead
of display->funcs.FEATURE, prefer display->FEATURE.funcs.

[PATCH 08/15] drm/i915/display: move display funcs under modeset sub-struct

[Jani Nikula]

Move generic crtc-ish modeset related functions under a new modeset
sub-struct of struct intel_display. Rename struct intel_display_funcs to
intel_modeset_funcs to make it a little bit more specific. Remove the
funcs sub-struct.

The funcs sub-struct of struct intel_display seems unnecessary. Instead
of display->funcs.FEATURE, prefer display->FEATURE.funcs.

[PATCH 09/15] drm/i915/irq: deduplicate dg1_de_irq_postinstall() and gen11_de_irq_postinstall()

[Jani Nikula]

dg1_de_irq_postinstall() and gen11_de_irq_postinstall() are exactly the
same. Remove dg1_de_irq_postinstall() and call
gen11_de_irq_postinstall() instead.

The location of the intel_lpe_audio_irq_handler() call seems too

This thing acks the irq too, so I believe it needs to stay here.

That was lost on me with the rabbit hole the lpe irq handler is.

I think I can put this in the intel_display_irq_ack() part, although the
name becomes misleading as it also handles some parts. Oh well.

[PATCH 11/15] drm/i915/irq: constify pipe stats parameters

The pipe stat irq handling doesn't need to modify the pipe stats
arrays. Make them const.

[PATCH 12/15] drm/i915/irq: add display irq funcs, start with intel_display_irq_reset()

[Jani Nikula]

Introduce display irq hooks with struct intel_display_irq_funcs, and add
the ->reset hook as the first thing. Call the reset hooks from i915 and
xe core via intel_display_irq_reset().

[PATCH 14/15] drm/i915/irq: add intel_display_irq_ack() to irq funcs

[Jani Nikula]

Some platforms have a separate step for acking display irqs. Call the
platform specific display irq ack hooks, if any, via
intel_display_irq_ack().

Introduce struct intel_display_irq_state to group together all the data
the ack hooks need. In the follow-up, this state will be passed on to a
shared handler function.

[PATCH 15/15] drm/i915/irq: add intel_display_irq_handler() to irq funcs

[Jani Nikula]

Call the platform specific display irq handler hooks via
intel_display_irq_handler(). Add master_ctl to struct
intel_display_irq_state, and pass the state pointer to the handler where
necessary.

I would prefer a function rather than the extra variable. The other
option is to just use the CHV mask always. There is nothing on the
extra bit on VLV so we never unmask it.

Ideally I'd like a separate structs for different platforms,
but until I resurrect my old ack vs. handle split for all
platforms I guess we don't need anything else here for
ilk+. So good enough for now I suppose.

Hmm. reset and postinstall also have slight variations for VLV vs. CHV,
but only very slight. I think they're overall close enough that
splitting out a funcs struct and separate funcs for CHV is more
distracting and duplication than helpful.

Or would something like this be satisfactory? Just a couple of small
wrapper functions around intel_lpe_audio_irq_handler() here that the
compiler would just inline:

	if (display->platform.cherryview)
		chv_lpe_audio_irq_handler(display, state->iir);		
	else
		vlv_lpe_audio_irq_handler(display, state->iir);		

Of course this would need to move to the ack part per your other review
comment.

You mean per-platform substructs/unions within struct
intel_display_irq_state? I can do that.

I think with DPINVGTT we could just switch to using full 16bit masks
and get rid of the vlv/chv difference. I should check if the unused
bits are all tied to 0...

I was just thinking of having something like 
vlv_lpe_irq_mask()
{
	if (chv)
		return ...;
	else
		return ...;
}

Yeah something like that. Not super important right since
we just have the master_ctl for non-gmch platforms.
