Small note here. It is not just commit description that changed. Also
error value of intel_alpm_init_dpcd is handled and there is early exit
in intel_edp_init_dpcd.

Why not propagate the original error instead of flattening to a boolean?
What does boolean true/false mean for a function that's not a predicate
function but "init"?

From a maintenance perspective, the mixing of bool vs. int return values
is a problem because you never know what is being checked for in the
caller side:

	if (!intel_alpm_init_dpcd())

Does that return bool and false means failure? Or does that return int
and false means success?!

Jani.

false indicates that it is not correctly initialized.
Got your concern, will try to keep return value as int.

[PATCH v6 03/18] drm/i915/alpm: alpm_init() for DP2.1

[Animesh Manna]

Initialize ALPM for DP2.1 and separate out ALPM mutex-init
from alpm-init.

v2: Separate out mutex-init. [Jani]
v3: Refactor further to avoid DISPLAY_VER check in multiple places. [Jani]
v4: Cosmetic changes. [Suraj]
v5: Reset alpm_dpcd and simplify source-supported check.
v6: Drop display-version check for eDP for backward compatible.

[Severity: Medium]
Does clearing this capability flag during the detect callback cause a 
hardware state leak on hot-unplug?

When an active display is hot-unplugged, intel_dp_detect() runs and zeroes 
intel_dp->alpm_dpcd here. However, userspace will subsequently issue an 
atomic commit to disable the CRTC. 

During that disable sequence, intel_alpm_disable() in intel_alpm.c checks 
intel_dp->alpm_dpcd to see if it should proceed. Since the capability was 
already cleared, the check evaluates to false and the function exits early. 
This skips the register cleanup, leaving the transcoder's ALPM_CTL hardware 
registers enabled.

This is done already for eDP. You could make it conditional to
!intel_dp_is edp.

I also found it a bit confusing why alpm_init_dpcd is conditional to
intel_alpm_source_supported in case of DP but not in case of eDP. How
about moving intel_alpm_source_supported in intel_alpm_init/_dpcd?

[PATCH v6 04/18] drm/i915/alpm: Enable debugfs for DP2.1

[Animesh Manna]

Enable ALPM debug info through lobf debug info.

v2: cosmetic change. [Suraj]
v3: Use common api instead of DISPLAY_VER check in multiple places. [Jani]
v4: Add display-version check as it dropped for EDP.

These are named as i915_edp_lobf_debug even if they are created on DP
connector.

We have couple of options,
i) rename to i915_lobf_debug, but backward compatibility will be broken.
ii) create a new debugfs for dp - i915_dp_lobf_debug. Code duplication will be there.
ii) as LOBF introduced first on edp to so DP will use existing edp-interface. 

Good to know your opinion, I see all these options have pros and cons.

I would vote for naming both as i915_lobf_debug. DP/eDP is already in
connector path. Code (IGT in practice) could first try new interface
and then if not found try old naming.

Here you could return SILENCE_PERIOD_TIME + t1 + tcds.

I think you should keep num_ml_phy_lock also in your helper. Just to
keep readability. Also in patch 6 you will have then:

if (intel_crtc_has_type(crtc_state, INTEL_OUTPUT_EDP)) {
	num_ml_phy_lock = 7 + DIV_ROUND_UP(6500, tml_phy_lock) + 1;
} else {
...
	num_ml_phy_lock = 7;
...

tcds = num_ml_phy_lock * tml_phy_lock;

[PATCH v6 06/18] drm/i915/alpm: Auxless wake time calculation for Xe3p

[Animesh Manna]

Add support for auxless waketime calculation for DP2.1 ALPM
as dependent parameter got changed.

v1: Initial version.
v2: Use intel_dp_is_uhbr(). [Jani]
v3:
- Separate out switch to active latency calculation.
- Use macro definition for ML_PHY_LOCK length. [Suraj]
v4:
- Fix 32-bit signed integer overflow. [sashiko]
- Fix negative return of drm_dp_lttpr_count(). [sashiko]
- Introduce get_ml_phy_lock_len() and get_dp_link_symbol_size(). [Jouni]
- Align variable naming with bpec formula of establishment_period. [Jouni]

tml_phy_lock:

For 8b/10b: 
252 Symbol clocks * ( 10 / (Link Rate in Mbps) )

For 128b/132b:
396 Super Symbol clocks * ( 32/ (Link Rate in Mbps) )

In comment you should have:
* (10000 * 10000)/intel_dp_link_symbol_size()

[PATCH v6 07/18] drm/i915/alpm: Modify AUX_LESS_WAKE_TIME bitfield for xe3lpd

[Animesh Manna]

The AUX_LESS_WAKE_TIME bitfield in ALPM_CTL is widened from 6 bits to
8 bits starting from xe3lpd (display version 35). Add the register mask
and field macro for the wider bitfield and program the wake time using
the appropriate macro based on the display version.

v2: Modify AUX_LESS_WAKE_TIME bitfield for xe3lpd. [Suraj]
v3: Separate out AUX_LESS_WAKE_TIME bitfield change into its own
patch. [Jouni]

commit fefc7fdf839fcf4154d50e19eac0f82242cca5ad
Author: Animesh Manna <animesh.manna@intel.com>
Subject: drm/i915/alpm: Modify AUX_LESS_WAKE_TIME bitfield for xe3lpd

This commit widens the ALPM_CTL_AUX_LESS_WAKE_TIME bitfield from 6 bits
to 8 bits for xe3lpd (display version 35) and later. It introduces new
register macros and updates lnl_alpm_configure() to program the wake time
using the appropriate macro based on the display version.

[Severity: Medium]
While this successfully programs the wider 8-bit wake time on xe3lpd hardware,
does _lnl_compute_aux_less_alpm_params() in the same file also need to be
updated to use this new mask?

Looking at _lnl_compute_aux_less_alpm_params(), the bounds check is still
hardcoded to the 6-bit legacy mask ALPM_CTL_AUX_LESS_WAKE_TIME_MASK on all
platforms:

	if (aux_less_wake_lines > ALPM_CTL_AUX_LESS_WAKE_TIME_MASK ||
	    silence_period > PORT_ALPM_CTL_SILENCE_PERIOD_MASK ||
	    lfps_half_cycle > PORT_ALPM_LFPS_CTL_LAST_LFPS_HALF_CYCLE_DURATION_MASK)
		return false;

Will this restrict aux_less_wake_lines to a maximum of 63, causing validation
to fail and aborting ALPM if the computed wake time is larger on xe3lpd?

Additionally, the safest params fallback is also restricted to the legacy mask:

	if (display->params.psr_safest_params)
		aux_less_wake_lines = ALPM_CTL_AUX_LESS_WAKE_TIME_MASK;

Will this cap the safest params to 63 instead of 255 on xe3lpd?

You should modify _lnl_compute_aux_less_wake_time to take this change
into account.

[PATCH v6 08/18] drm/i915/alpm: table based establishment period

[Animesh Manna]

Only use the table when the link rate is listed (idx valid)
and the LTTPR count is within the table bounds. A zero entry
means the rate has no tabulated value, so fall back to the
computed establishment period below.

Note: The table and its values are taken from DP2.1 vesa spec.

v2: Add check for negative error codes from drm_dp_lttpr_count(). [sashiko]

Difference between what this table is giving us and what we are getting
from the formula is coming from SILENCE_PERIOD_TIME and tlfps_period.
In DP spec they are using max values while our calculation is using
midpoint.

I think we could just switch to max values on these and drop adding
tables completely.

This would unnecessarily increase our wake-time. Maybe we could just
accept the difference between calculated and pre-calculated values as
we understand where it comes from? We are using mid point in the
configuration and that is what we use in wake time calculation as well.
Values table from VESA spec are calculated using max values.

As per I know the formula-based approach with max values also little short from the values coming from Vesa spec. This is found little sensitive during ALPM testing on specific test setup and resulting flip-done timeout. To overcome the issue currently prefer to direct values from vesa spec. And if not present will fallback to formula based approach.

drm/i915/alpm: Half LFPS cycle calculation

This commit adds support for half LFPS cycle calculation for DP2.1 ALPM
as dependent parameters got changed.

[Severity: High]
Does this function leave min and max completely uninitialized for
non-eDP configurations?

For instance, when connecting an external DisplayPort sink on LunarLake
with ALPM capabilities, intel_crtc_has_type(..., INTEL_OUTPUT_EDP) would
be false, and the function returns without setting these parameters.

>  
>  	return tlfps_cycle_min +  (tlfps_cycle_max - tlfps_cycle_min) / 2;
>  }

[Severity: High]
Can these stack variables be consumed while still uninitialized?

Because lnl_get_lfps_period_min_max_time() lacks a non-eDP fallback, it
appears tlfps_cycle_min and tlfps_cycle_max could retain their uninitialized
stack values here when called for a standard DisplayPort setup.

These garbage values would then be used in the arithmetic calculation and
subsequently programmed into hardware ALPM registers. Could this potentially
cause display link corruption, link training failures, or hardware timeouts?

As you are checking HAS_LT_PHY better prefix would be lt_.

Just realized that this has to be
intel_dp_link_symbol_clock(crtc_state>port_clock). For eDP it have been
working as crtc_state->port_clock ==
intel_dp_link_symbol_clock(crtc_state>port_clock) always.

Maybe also good to rename this as get_lfps_half_cycle_symbols.

[PATCH v6 11/18] drm/i915/alpm: Modify LFPS_CYCLE_COUNT bitfield for xe3lpd

[Animesh Manna]

The LFPS_CYCLE_COUNT bitfield in PORT_ALPM_LFPS_CTL is widened from
4 bits (27:24) to 7 bits (30:24) starting from xe3lpd. Add the wider
register mask and field macro, and program the cycle count using the
appropriate macro based on the display version.

v2: Split in a separate patch. [Jouni]

[Severity: Medium]
Does this assignment to a u32 variable cause error codes to go unhandled?

The function drm_dp_lttpr_count() can return negative error codes like
-ERANGE or -EINVAL on failure. If this happens, assigning it to the unsigned
lttpr_count variable strips the negative sign and results in a large value
being passed into ALPM_CTL2_NUMBER_OF_LTTPR(). This could corrupt the
register programming by injecting invalid bits via REG_FIELD_PREP.

[Severity: Low]
This isn't a bug, but the comment specifies "less than 0x20", while the
code below implements a less than or equal to 0x20 (<= 0x20) check.

> +	if (!intel_dp_is_edp(intel_dp) ||
> +	    lttpr_count < 0 ||

[Severity: Low]
Is this lttpr_count < 0 check reachable?

In intel_dp_start_link_train(), the lttpr_count is clamped to 0 on error
before being passed to this function:

	if (lttpr_count < 0)
		/* Still continue with enabling the port and link training. */
		lttpr_count = 0;

	intel_dp_prepare_link_train(intel_dp, crtc_state);
	intel_dp_update_lttpr_count(intel_dp, lttpr_count);

> +	    intel_dp->lttpr_common_caps[0] <= 0x20)

[Severity: High]
Can this LTTPR programming ever be reached for either DP or eDP configurations?

For standard DP connections, the function returns immediately because of the
!intel_dp_is_edp(intel_dp) check above.

For eDP connections, intel_dp_init_lttpr_and_dprx_caps() explicitly skips
LTTPR capabilities initialization, leaving intel_dp->lttpr_common_caps[0]
as 0. That causes the function to also return immediately due to this
<= 0x20 check, rendering the feature unreachable.

No need to check this. It's already set as 0 in start_link_train if <

[PATCH v6 13/18] drm/i915/alpm: Enable MAC Transmitting LFPS for LT PHY

[Animesh Manna]

Enable MAC to transmit LFPS via LT PHY during aux-less alpm.

v2:
- Correct commit description. [Suraj]
- Remove loop as no dependency on the transmitter LT_PHY_CMN_CTL0. [Suraj]
v3: Cosmetic changes. [Suraj]

LT_PHY_CMN_MAC_TRANSMIT_LFPS would better follow what is in Bspec.

[PATCH v6 14/18] drm/i915/alpm: Replace is_edp() with alpm_is_possible()

[Animesh Manna]

Add a separate alpm_is_possible() which will check for alpm
capability from dpcd info.

v2: Drop DISPLAY_VER() check as intel_alpm_source_supported
already checking and populating dpcd info. [Jouni]

commit f95070b21da14e9f299aa7eaa97682597723ecc9
Author: Animesh Manna <animesh.manna@intel.com>
Subject: drm/i915/alpm: Replace is_edp() with alpm_is_possible()

This commit introduces a separate intel_alpm_is_possible() function to
check for ALPM capability from DPCD information, replacing earlier checks
that relied solely on the panel being eDP.

[Severity: High]
Does this logic correctly enforce DP requirements for ALPM?

It looks like this uses a logical OR instead of requiring both the sink and
LTTPR to support ALPM. Additionally, this seems to access the raw capability
byte without masking the specific ALPM capability bit, which could mean
reserved bits will be evaluated as true. 

Can this break standard DP link training invariants when connecting a display
with LTTPRs that support ALPM while the sink does not, or when a sink has
reserved bits set but no ALPM support?

[Severity: High]
Could this dynamic capability check cause ALPM_CTL to be left enabled during
a hot-unplug event?

During a hot-unplug event, the cached DPCD capabilities like alpm_dpcd can
be cleared before the teardown hooks execute. Because this teardown function
checks these dynamic capabilities via intel_alpm_is_possible() instead of
the old hardware state, it might return early and fail to clear the ALPM_CTL
hardware register.

Would this leave the transcoder with ALPM enabled when it is supposed to be
disabled, potentially causing state mismatches on subsequent modesets?

I think rather than converting these you should remove these checks
from enable and disable. LOBF is not supposed to be enabled in
new_crtc_state if "!intel_alpm_is_possible()"

[PATCH v6 15/18] drm/i915/alpm: Introduce has_alpm to decouple from pr/psr2/lobf

[Animesh Manna]

For DP2.1, ALPM (Advanced Link Power Management) is optional: Panel
Replay can be supported without ALPM. Until now ALPM enablement was
derived implicitly from other features - eDP Panel Replay and PSR2
always implied ALPM (intel_psr_needs_alpm()), while LOBF was tracked
separately via has_lobf - so this scattered, feature-coupled logic
cannot express "Panel Replay without ALPM".

Introduce a single crtc_state->has_alpm flag as the source of truth for
whether ALPM is enabled for a pipe configuration, computed during config
validation:

 - Panel Replay: from alpm_config_valid() when ALPM is possible; eDP
   Panel Replay additionally requires has_alpm.
 - PSR2 / Selective Update: from intel_alpm_is_possible().
 - LOBF: from has_lobf.

The Panel Replay path sets has_alpm speculatively, so clear it when
Panel Replay is not the finally selected feature, ensuring a PSR1
fallback never enables ALPM.

Use has_alpm in place of the feature-specific checks in the ALPM
configure, port configure, sink enable and MAC-transmit-LFPS paths, and
key the late wake-line selection off has_alpm / has_panel_replay.

Also rename intel_alpm_is_alpm_aux_less() to intel_alpm_is_aux_less()
and base the aux-less decision on has_panel_replay, keeping the source
programming consistent with the sink's DP_ALPM_MODE_AUX_LESS. The now
unused intel_psr_needs_alpm() is removed.

commit 4dcfef3fd89e0ed18372dabec785892c009d57eb
Author: Animesh Manna <animesh.manna@intel.com>
Subject: drm/i915/alpm: Introduce has_alpm to decouple from pr/psr2/lobf

This commit introduces a single crtc_state->has_alpm flag to track ALPM
enablement, decoupling it from implicit feature tracking like eDP Panel
Replay, PSR2, or LOBF. It updates various ALPM configuration and port
paths to use this new flag as the single source of truth.

[Severity: Medium]
Does this missing check for crtc_state->has_alpm cause incorrect
PR_ALPM_CTL programming?

The intel_alpm_is_aux_less() function evaluates to true for Panel Replay
regardless of the actual has_alpm state. Without an explicit check verifying
that ALPM is actually active, if Panel Replay is explicitly falling back to
a "without ALPM" configuration, this loop will incorrectly write AS SDP
parameters to the ALPM controller, which contradicts the fallback state.

[Severity: Medium]
Will this early return prevent clearing stale ALPM state in the hardware?

Previously, this function would proceed and write the zeroed alpm_ctl_val
and lfps_ctl_val to the hardware when ALPM was disabled. By returning
early when crtc_state->has_alpm is false, any transition from an
ALPM-enabled mode to an ALPM-disabled mode will skip the clearing writes.
This leaves the hardware with an active ALPM configuration while the driver
state considers it disabled.

[Severity: High]
Does this unconditional assignment overwrite the validated has_alpm state?

The Panel Replay configuration path sets has_alpm based on whether ALPM
timing actually fits into the vblank period. When Panel Replay is validated
but ALPM timing fails, has_alpm is correctly set to false to allow Panel
Replay without ALPM.

This line in intel_sel_update_config_valid() unconditionally overwrites
that calculated state with a simple capability check, forcing it back to
true. This destroys the fallback state, causing the late compute config
to evaluate ALPM wake lines again, fail, and fully disable Panel Replay
on external DP.

[Severity: High]
Does retaining the eDP-only check in intel_psr_needs_alpm_aux_less()
prevent AS SDP configuration for external DP Panel Replay?

While intel_alpm_is_aux_less() was updated to support external DP,
intel_psr_needs_alpm_aux_less() still restricts true return values to
eDP only. Any external DP configuration enabling Panel Replay will fail
this check when evaluated by intel_dp_pr_with_as_sdp_enabled() in the
link training paths.

This leads to silently missing the DP_FIXED_VTOTAL_AS_SDP_EN_IN_PR_ACTIVE
configuration during link training, causing a mismatch between source
programming and the sink DPCD configuration.

[Severity: High]
Can has_alpm leak as true if PSR or Panel Replay features are disabled
late in this function?

When falling back to PSR1 or fully disabling PSR due to vblank timing limits
or hardware workarounds later in intel_psr_compute_config_late():

    if (crtc_state->has_panel_replay) {
            crtc_state->has_panel_replay = false;
            crtc_state->has_psr = false;
    }
    crtc_state->has_sel_update = false;

The corresponding feature flags are cleared, but has_alpm is left as true.
Since ALPM programming paths (like intel_alpm_port_configure) now rely
directly on has_alpm, this leaked state can cause unintended ALPM hardware
programming on unsupported modes.

For PSR2 right place for this is in intel_psr2_config_valid. There is
already alpm_config_valid call.

I would rather set it in one place. At the end of
intel_psr_compute_config_late if doing it this way.

I would rather target to have :

1. alpm_compute_config ()
   doing intel_alpm_compute_params. Setting two new flags in
alpm_state->aux_less_possible and alpm_state->aux_wake_possible. Also
doing what lobf_compute_config is doing now.

2. psr_compute_config
   using values/flags computed by alpm_compute_config and choosing  
psr/psr2/pr based on those.
...

3. psr_compute_config_late
   no changes.

4. alpm_compute_config_late
   set has_lobf and has_alpm based on calculation by
alpm_compute_config, psr_compute_config and psr_compute_config_late.

Next logical move after this would be to have the configuration of ALPM
happening in one place. Not needed in this patch set though.

[PATCH v6 16/18] drm/i915/alpm: Compute and program switch to active latency

[Animesh Manna]

Program the ALPM switch to active latency into ALPM_CTL2. For UHBR link
rates the latency is derived from the link symbol clock and converted to
scanlines, for non-UHBR rates it is zero.

v2: Use macro instead of magic number wherever possible. [Jouni]

commit 6e4638c7fe4ea7d79d2000aac2b17f2fc3edc381
Author: Animesh Manna <animesh.manna@intel.com>
Subject: drm/i915/alpm: Compute and program switch to active latency

This commit programs the ALPM switch to active latency into ALPM_CTL2. For
UHBR link rates, the latency is derived from the link symbol clock and
converted to scanlines, while for non-UHBR rates it is set to zero.

[Severity: High]
Does this logic incorrectly substitute the symbol rate for the bit rate,
inflating the latency by 32x?

In the DP spec formula, fLink is the link rate in Mbps, and multiplying the
symbol count by 32 correctly calculates bits divided by bit-rate. However,
symbol_clock is calculated here as port_clock / 32, meaning the denominator is
32x smaller than intended.

This math error calculates a latency of ~47.4us instead of 1.48us, causing
excessively long ALPM wake sequences. Additionally, standard integer division
here drops fractional microseconds, so if corrected, the wait time might be
shorter than the physical hardware minimum on high-clock displays.

[Severity: High]
Can the computed scanline count overflow the 5-bit register field it is
later written to?

Unlike the other parameters configured in _lnl_compute_aux_less_alpm_params(),
there is no bounds check here against the maximum allowed value before
assigning it to switch_to_active.

With the 32x inflation bug above, on high-refresh-rate displays (like 4K @
360Hz), ~47us translates to > 31 scanlines.

[Severity: High]
Does this silently mask and truncate the unbounded scanline count?

ALPM_CTL2_SWITCH_TO_ACTIVE_LATENCY uses REG_FIELD_PREP with a 5-bit mask.
Any value > 31 is silently truncated. For example, 32 scanlines truncates
to 0, completely removing the required wake latency. This causes the hardware
to exit ALPM before the PHY has locked, leading to link training failures or
display corruption.

[PATCH v6 17/18] drm/i915/alpm: Program zero-based LFPS half cycle duration

[Animesh Manna]

The LFPS Half Cycle Duration field, as well as the First and Last LFPS
Half Cycle Duration fields, in PORT_ALPM_LFPS_CTL are zero-based: per
Bspec the value programmed must be N_Symbol - 1. The number of symbols
was programmed directly, making each half cycle one symbol clock too
long.

Subtract one in the PORT_ALPM_LFPS_CTL_LFPS_HALF_CYCLE_DURATION,
PORT_ALPM_LFPS_CTL_FIRST_LFPS_HALF_CYCLE_DURATION and
PORT_ALPM_LFPS_CTL_LAST_LFPS_HALF_CYCLE_DURATION field macros so the
programmed value matches the zero-based field encoding.

Bspec: 71632

[Severity: Medium]
Since this macro now subtracts 1 for zero-based encoding, does the bounds
check in _lnl_compute_aux_less_alpm_params() also need to be updated?

drivers/gpu/drm/i915/display/intel_alpm.c:_lnl_compute_aux_less_alpm_params() {
	...
	if (aux_less_wake_lines > ALPM_CTL_AUX_LESS_WAKE_TIME_MASK ||
	    silence_period > PORT_ALPM_CTL_SILENCE_PERIOD_MASK ||
	    lfps_half_cycle > PORT_ALPM_LFPS_CTL_LAST_LFPS_HALF_CYCLE_DURATION_MASK)
		return false;
	...
}

It looks like this check restricts the maximum allowed symbols to 31 (the
mask value). With the new zero-based encoding, shouldn't a value of 32 be
permitted? If lfps_half_cycle is 32, this bounds check will return false,
which could artificially restrict the limit and reject valid hardware
display configurations.

[PATCH v6 18/18] drm/i915/alpm: Disallow ALPM for UHBR link rate

[Animesh Manna]

DP2.1 ALPM is not supported on UHBR (128b/132b) link rates on the NVL
platform. Reject the ALPM parameter computation for external DP running
at a UHBR rate on display version 35, so that ALPM (and the Panel Replay
and LOBF features that rely on it) is not enabled in that case. eDP is
excluded so eDP ALPM keeps working at any link rate.

drm/i915/alpm: Disallow ALPM for UHBR link rate

This commit attempts to reject ALPM parameter computation for external DP
running at a UHBR rate on NVL platforms. eDP is explicitly excluded from this
check to keep eDP ALPM working at all link rates.

[Severity: High]
Does returning false here successfully prevent ALPM and Panel Replay from being
enabled on external DP?

Looking at _panel_replay_compute_config() in
drivers/gpu/drm/i915/display/intel_psr.c, there is an early return for non-eDP
displays:

    if (!intel_dp_is_edp(intel_dp))
        return true;

    /* Remaining checks are for eDP only */

    if (!crtc_state->has_alpm)
        return false;

Because of this early return, the failed ALPM parameter computation is bypassed
for external DP. Later in intel_sel_update_config_valid(), has_alpm is
unconditionally overwritten:

    crtc_state->has_alpm = intel_alpm_is_possible(intel_dp);
    return true;

Could this sequence leave ALPM and Panel Replay enabled with uninitialized
(zeroed) wake lines and times, potentially violating DP specifications and
preventing the external display from waking up correctly?

I think more logical place for this would be in intel_alpm_is_possible.
