[CI 00/32] [PATCH 00/32] drm/i915/display: Add MTL+ platforms to support dpll framework

[Mika Kahola]

This is v2 of [1], with the following changes

- Add support for eDP on C20 phy pll on PantherLake.

- As required by the above point use the non_tc_phy instead of c10phy term
  for the PLL hooks computing the state for, getting/putting etc. the PLLs
  of the non TypeC ports/outputs (on port A and B). Use the tc_phy instead
  of the c20phy term for the PLLs of all the other TypeC ports/outputs
  (port TC1-4).Support for eDP on C20 phy pll on PantherLake.

[CI 03/32] drm/i915/display: Sanitize setting the Cx0 PLL use_c10 flag

[Mika Kahola]

From: Imre Deak <imre.deak@intel.com>

Sanitize setting the Cx0 PLL use_c10 flag during state computation and
HW readout, making sure they happen the same way in the
intel_c{10,20}pll_calc_state() and intel_c{10,20}pll_readout_hw_state()
functions.

Follow-up changes will add more state computation/HW readout, this
change prepares for those as well.

[CI 04/32] drm/i915/display: Sanitize calculating C20 PLL state from tables

[Mika Kahola]

From: Imre Deak <imre.deak@intel.com>

A follow up change adds a computation for the C20 PLL VDR state, which
is common to both the HDMI algorithmic and DP/HDMI table based method.
To prepare for that streamline the code. The C10 counterpart would
benefit from the same change, leave that for later adding a TODO
comment.

So this is something I have been meaning to fix we should really be using the HDMI tables already defined
Computing them ourselves, that should be reserved for only when we do not have any HDMI table for the said port clock available.
Also if we use the computed tables directly that means we never end up using the defined tables.

SO the flow here should be

err = intel_c20pll_calc_state_from_table(crtc_state, encoder);

if (err && intel_crtc_has_type(crtc_state, INTEL_OUTPUT_HDMI)))
	err = intel_c20_compute_hdmi_tmds_pll(crtc_state);

something like this.

This patch is not meant to change the logic, it simply wants to make the
logic clearer to the reader. What you suggest should be a separate
patch.

I am fine with that do you want to add that as a part of this series or should I send a separate
Patch fixing this.

I think that change is not in the scope of this patchset, so it would be
better if you could follow up with it separately.

[CI 05/32] drm/i915/display: Track the C20 PHY VDR state in the PLL state

[Mika Kahola]

From: Imre Deak <imre.deak@intel.com>

The Cx0 PLL enable programming needs to know if the PLL is in DP or HDMI
mode. The PLL manager framework doesn't pass the CRTC state to the PLL's
enable hook, so prepare here for the conversion to use the PLL manager
for Cx0 PHY PLLs by tracking the DP/HDMI mode in the PLL state.

This change has the advantage, that the VDR HW/SW state can be verified
now.

A follow up change will convert the PLL enable function to retrieve the
DP/HDMI mode parameter from the PLL state.

This also allows dropping the is_dp and port clock params from the
intel_c20_pll_program() function, since it can retrieve these now from
the PLL state.

[CI 06/32] drm/i915/display: Move definition of Cx0 PHY functions earlier

[Mika Kahola]

From: Imre Deak <imre.deak@intel.com>

Move the definitions of the
  intel_c10pll_calc_port_clock()
  intel_c20_get_dp_rate()
  intel_c20_get_hdmi_rate()
  is_hdmi_frl()
  is_dp2()
  intel_get_c20_custom_width()
functions earlier to avoid the forward declarations.

[CI 07/32] drm/i915/display: Add macro to get DDI port width from a register value

[Mika Kahola]

From: Imre Deak <imre.deak@intel.com>

A follow-up change will need to retrieve the DDI port field from the
register value, add a macro for this. Make things symmetric with setting
the field in the register.

[CI 08/32] drm/i915/display: Track the Cx0 PHY enabled lane count in the PLL state

[Mika Kahola]

From: Imre Deak <imre.deak@intel.com>

The Cx0 PLL enable programming requires the enabled lane count. The PLL
manager framework doesn't pass the CRTC state to the PLL's enable hook,
so prepare here for the conversion to use the PLL manager, by tracking
the enabled lane count in the PLL state as well. This has the advantage,
that the enabled lane count can be verified against the PHY/PLL's
enabled TX lanes.

This also allows dropping the lane count param from the
__intel_cx0pll_enable() function, since it can retrieve this now from
the PLL state.

[CI 09/32] drm/i915/display: Sanitize C10 PHY PLL SSC register setup

[Mika Kahola]

From: Imre Deak <imre.deak@intel.com>

Define the C10 PLL SSC register range via macros, so the HW/SW state of
these register can be verified by a follow-up change, reusing these
macros.

[CI 10/32] drm/i915/display: Read out the Cx0 PHY SSC enabled state

[Mika Kahola]

From: Imre Deak <imre.deak@intel.com>

Read out the C10, C20 PHY PLLs SSC enabled state, so the PLL HW/SW state
verification can check this state as well.

C10 PHY PLLs program some PLL registers zeroed out for the non-SSC case,
while programming non-zero values to the same registers for the SSC
case, so check that these PLL registers being zero or non-zero matches
the PLL's overall SSC-enabled state (stored in the
intel_c10pll_state::ssc_enabled flag).

[CI 11/32] drm/i915/display: Determine Cx0 PLL DP mode from PLL state

[Mika Kahola]

From: Imre Deak <imre.deak@intel.com>

The Cx0 PLL enable programming needs to know if the PLL is in DP or HDMI
mode. The PLL manager framework doesn't pass the CRTC state to the PLL's
enable hook, so prepare here for the conversion to use the PLL manager
for Cx0 PHY PLLs by determining the DP/HDMI mode from the PLL state.

For C10 PHYs use the fact that the HDMI divider value in the PLL
registers are set if and only if the PLL is in HDMI mode.

For C20 PHYs use the DP mode flag programmed to the VDR SERDES register,
which is set if and only if the PLL is in DP mode.

Assert that the above PLL/VDR SERDES register values match the DP/HDMI
mode being configured already during state computation.

This also allows dropping the is_dp param from the
__intel_cx0pll_enable() function, since it can retrieve this now from
the PLL state.

Wouldn't a simple check of drm_encoder's type tell us if it is dp or not ?

For a DDI encoder drm_encoder::encoder_type is DRM_MODE_ENCODER_TMDS,
from which you can't determine if the encoder is used for a DP or HDMI
output. This also applies to intel_encoder_is_dp(), which will return
true if for instance a DDI encoder wired to a DP++ connector is used for
an HDMI output.

[CI 12/32] drm/i915/display: Determine Cx0 PLL port clock from PLL state

[Mika Kahola]

From: Imre Deak <imre.deak@intel.com>

The port clock is tracked in the PLL state, so there is no need to pass
it separately to __intel_cx0pll_enable(). Drop the port clock function
param accordingly.

[CI 13/32] drm/i915/display: Zero Cx0 PLL state before compute and HW readout

[Mika Kahola]

From: Imre Deak <imre.deak@intel.com>

Ensure Cx0 pll state is initialized to zero before any computation or HW
readouts, to prevent leaving some parameter in the state uninitialized
in the actual compute/HW readout functions later.

Why? What if we hit this? At the very least please use
drm_WARN_ON(). What does the comment have to do with the WARN?

Besides after the loop i == ARRAY_SIZE(hw_state->mplla), i.e. the whole
thing can be

The WARN verifies that the additional entry to include in the print
exists and it is the only entry to print.

Yes, BUILD_BUG_ON() is better here, no reason for delaying the check
until runtime.

[CI 15/32] drm/i915/display: Remove state verification

[Mika Kahola]

When pll's are moved to dpll framework we no longer
need Cx0 specific state verification as we can rely
on dpll state verification instead.

[CI 17/32] drm/i915/display: Update C10/C20 state calculation

[Mika Kahola]

For the dpll framework, the state must be computed into
a port PLL state, which is separate from the dpll_hw_state
in crtc_state.

You have state the problem here but failed to mention what the commit does.
Also port PLL state?
Also two different changes are happening here struct crtc_state argument becomes
const struct crtc_state and a addition of a new param dpll_hw_state maybe these need
to be two separate patches.

So you are adding a new param which can be derived from the param you are still passing to
the function ?

Ok, I will try to reword the commit message to better reflect what the patch does.

Switching to const struct crtc_state seemed to me a small change that could embedded into this patch. I will try to reword commit message include reasoning for this change.

At this stage yes as the intel_cx0pll_calc_state() changed. This is, however, an intermediate step as we end up removing the whole mtl_crtc_compute_clock() function.

[CI 18/32] drm/i915/display: Compute plls for MTL+ platform

[Mika Kahola]

To bring MTL+ platform aligned with dpll framework we
need to call and calculate pll state from dpll
framework.

v2: Rename mtl_compute_c10phy_dpll() to mtl_compute_non_tc_phy_dpll().
    The state is computed either for a C10 or on the PTL port B eDP on
    TypeC PHY case for a C20 PHY PLL. Hence refer to this case as
    "non_tc_phy" instead of "c10phy".

    Rename mtl_compute_c20phy_dplls() to mtl_compute_tc_phy_dplls() for
    symmetry with mtl_compute_non_tc_phy_dpll().

Ditto 
Also try avoid statement like "we need to call.."
something like " To bring MTL+ platform aligned call & calculate PLL state from dpll framework

[CI 19/32] drm/i915/display: MTL+ .get_dplls

[Mika Kahola]

Add .get_dplls function pointer for MTL+ platforms
to support dpll framework. Reusing the ICL function
pointer.

v2: Getting configuration either for a C10 or on the PTL port B
    eDP on TypeC PHY case for a C20 PHY PLL. Hence refer to this
    case as "non_tc_phy" instead of "c10phy".

[CI 29/32] drm/i915/display: Add .enable_clock on DDI for MTL+ platforms

[Mika Kahola]

To enable pll clock on DDI we need to move part of the
pll enabling sequence to a ddi clock enabling function.

Simlilarly, we do the pll disabling sequence.

[CI 30/32] drm/i915/display: Get configuration for C10 and C20

[Mika Kahola]

For DDI initialization get configuration for C10 and C20
chips.

v2: Getting configuration either for a C10 or on the PTL port B
    eDP on TypeC PHY case for a C20 PHY PLL. Hence refer to this
    case as "non_tc_phy" instead of "c10phy".

[CI 31/32] drm/i915/display: Add Thunderbolt support

[Mika Kahola]

From: Imre Deak <imre.deak@intel.com>

Add the PLL hooks for the TBT PLL on MTL+. These are simple stubs
similarly to the TBT PLL on earlier platforms, since this PLL is always
on from the display POV - so no PLL enable/disable programming is
required as opposed to the non-TBT PLLs - and the clocks for different
link rates are enabled/disabled at a different level, via the
intel_encoder::enable_clock()/disable_clock() interface.

[CI 32/32] drm/i915/display: Enable dpll framework for MTL+

[Mika Kahola]

Now that MTL+ platforms are supported by dpll framework
we can remove a separate check for hw comparison and
rely solely on dpll framework hw comparison.

Finally, we have all required hooks in place so we can
initialize the PLL manager for MTL+ platforms and remove
the redirections to the legacy code paths from the following
interfaces:

* intel_encoder::clock_enable/disable()
* intel_encoder::get_config()
* intel_dpll_funcs::get_hw_state()
* intel_ddi_update_active_dpll()
* pipe_config_pll_mismatch()
