[RFC PATCH 0/9] drm/i915/display: DC3CO support

[RFC PATCH 0/9] drm/i915/display: DC3CO support

[Dibin Moolakadan Subrahmanian]

Hi all,

This series introduces initial DC3CO DC state support,
replacing the existing PSR2-based TGL DC3CO design
(currently disabled).

The goal of this work is to move DC3CO handling out of PSR2-specific
code paths and into the core atomic display state flow, making the
behaviour consistent across PSR, ALPM and LOBF in line with the new
DC3CO design.

This series is posted as RFC to gather early feedback on the approach
before full integration.

Dibin Moolakadan Subrahmanian (9):
  drm/i915/display: Remove TGL DC3CO support
  drm/i915/display: Replace DC_STATE_EN_DC3CO with
    DC_STATE_EN_UPTO_DC3CO
  drm/i915/display: Add DC3CO enable/disable support
  drm/i915/display: Add DC3CO eligibility logic
  drm/i915/display: Track DC3CO enable source
  drm/i915/display: alpm enable DC3CO support
  drm/i915/display: psr enable DC3CO support
  drm/i915/display: Add intel_dc3co_can_enable() helper
  drm/i915/display: Add DC3CO disable handling for psr2

[PATCH 1/9] drm/i915/display: Remove TGL DC3CO support

[Dibin Moolakadan Subrahmanian]

Remove all Tiger Lake DC3CO-related functions, as the feature is no
longer used. The existing structure members are intentionally left in
place and will be cleaned up in subsequent patches.

[PATCH 2/9] drm/i915/display: Replace DC_STATE_EN_DC3CO with DC_STATE_EN_UPTO_DC3CO

UPTO_DC* enable bits.

[PATCH 3/9] drm/i915/display: Add DC3CO enable/disable support

[Dibin Moolakadan Subrahmanian]

Add explicit handling for DC3CO in the dc_off power well sequencing.
Introduce xe3lpd_enable_dc3co() and wire it into the dc_off power
enable flow. gen9_disable_dc_states() is also updated to disable the
corresponding DMC wakelock when transitioning out of DC3CO.

[PATCH 4/9] drm/i915/display: Add DC3CO eligibility logic

[Dibin Moolakadan Subrahmanian]

Introduce dc3co_allow in struct intel_display and determine DC3CO
eligibility during atomic_check(). DC3CO is permitted only when:

  - the active pipe drives eDP,
  - the pipe is single-pipe (no joiner),
  - the pipe/port combination supports DC3CO.

When eligible, intel_atomic_commit_tail() programs the target DC state
as DC_STATE_EN_UPTO_DC3CO; otherwise we fall back to DC6. Update the
PSR vblank enable/disable path to follow the same policy.

Also extend get_allowed_dc_mask() to expose DC3CO support on
DISPLAY_VER >= 35.

[PATCH 5/9] drm/i915/display: Track DC3CO enable source

[Dibin Moolakadan Subrahmanian]

Introduce a bitmask enum intel_dc3co_source to record which display
features (PSR2, ALPM, LOBF) contribute to allowing DC3CO entry.
The source tracking is added here and will be integrated into the DC3CO
allow logic in follow-up commits.

This source concept is generally confusing. More specifically
DC3CO_SOURCE_ALPM I don't understand:

PSR and LOBF are methods to allow switching link off. ALPM is a method
to switch the link off. DC3CO and DC6 are Display power saving states
which are possible as the link is switched off.

Thank you for comments , I want to track the reason for enabling DC3CO.
I will remove DC3CO_SOURCE_ALPM as you pointed, but want to keep
DC3CO_REASON_PSR2 and DC3CO_REASON_LOBF .

For both LOBF and PSR dc3co will be enabled from intel_atomic_commit_tail() it self.
This patch selects DC6 after 6 idle frames for PSR.

This is for PSR and pretty much following existing (disabled) TGL DC3CO

control. What is your idea how selection between DC6 and DC3CO will be

done in case of LOBF?

For both LOBF and PSR dc3co will be enabled from intel_atomic_commit_tail() it self.

This patch selects DC6 after 6 idle frames for PSR.

But how you are planning to do the same for LOBF? I think they should have common control.

Very few files should touch display->power, and this is not one of them.

'git grep "display->power" -- drivers/gpu/drm/i915/display'

When is it okay to call this function and expect to get sane results?

That's a really complicated way to say

	return num_pipes == 1 && pipe <= PIPEB && port <= PORT_B;

What does "check" mean here? Or in *any* function?

Check sounds like something that's a pure function that doesn't change
anything... but this does.

That's now cached state with no stated rules on when it's valid and when
it's not.

intel_display.[ch] is not the dumping ground for random new code. The
goal is to *reduce* the size of it, not increase.

There's currently one place in intel_psr.c that checks
power_domains->allowed_dc_mask, and I think even that is too much.

display->power belongs to intel_display_power*.c, and nobody else.

I think you probably need a helper function to ask for this stuff from
power modules.

Yes, git grep shows few files , I will try to move all dc3co functions to
drivers/gpu/drm/i915/display/intel_display_power.c.

display->power.dc3co_allow is only updated in intel_dc3co_allow_check() which is called from
intel_atomic_commit_tail().intel_dc3co_allowed() only intended to be called from intel_post_plane_update()
path(ALPM/PSR), which executes as part of intel_atomic_commit_tail().

I will split this function to two , one for check and one for initialization

This function needs encoder,port and pipe information, which is why I added
it in intel_display.c.However,I agree it is updating dc3co_allow . I will check if
it can be moved to intel_display_power.c.

I will add more details.
The intent is to record PSR2 as the source enabling DC3CO.
DC3CO can be entered when either PSR2 or LOBF is enabled, and
dc3co_source is used to track which feature triggered it.

I will add more details to commit message .
On TGL, original code disabled DC3CO after 6 consecutive idle frames and
re-enabled DC6. That logic was removed for the new DC3CO design. This patch
restores the behavior in PSR2, switching from DC3CO to DC6 after 6 idle
frames to maintain correct power management.

Thanks for pointing this out.
I will add a helper function in intel_display_power.c to query this
instead of accessing display->power directly.

The point being, you have a complicated set of rules, and who's going to
know them and how when reading the code?
