[PATCH v7 01/20] 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.

Since the fields now encode 1 to 32 symbols, update the bounds check
in _lnl_compute_aux_less_alpm_params() to accept a half cycle of 32
symbols and reject 0, which cannot be encoded.

v2: Adjust half cycle bounds check for zero-based encoding. [sashiko]

[PATCH v7 02/20] drm/dp: Add DPCD definitions for DP2.1 ALPM capability

[Animesh Manna]

Add the LTTPR ALPM capabilities register (0xf0009) with the AUX-less
ALPM supported bit, and the total LTTPR count register (0xf000a), both
added in DP2.1. They are needed to enable DP2.1 ALPM with LTTPRs.

Extend DP_LTTPR_COMMON_CAP_SIZE from 8 to 10 so that the LTTPR ALPM
capability is read as part of the LTTPR common capabilities. This makes
drm_dp_read_lttpr_common_caps() read two more bytes for all its users,
DP_PHY_REPEATER_EQ_DONE (0xf0008) and DP_LTTPR_ALPM_CAPABILITIES
(0xf0009). The existing helpers don't use these bytes.

v2: Add DP_LTTPR_AUX_LESS_ALPM_SUPPORTED bit definition.
v3: Use drm/dp prefix and describe the DP_LTTPR_COMMON_CAP_SIZE change.

[PATCH v7 04/20] 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.
v7:
- Read ALPM DPCD in detect only for DP, eDP already does it. [Jouni]
- Move source-supported check into intel_alpm_init/_dpcd(). [Jouni]
- Check source support instead of sink caps in intel_alpm_disable()
  as alpm_dpcd is reset on disconnect before the CRTC is disabled.

[PATCH v7 05/20] drm/i915/alpm: Enable debugfs for DP2.1

[Animesh Manna]

Enable ALPM debug info through lobf debug info.

As LOBF debugfs entries are now created for both DP and eDP connectors,
rename i915_edp_lobf_debug/i915_edp_lobf_info to i915_lobf_debug/
i915_lobf_info. The connector type is already part of the debugfs path.

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.
v5:
- Rename debugfs entries to i915_lobf_debug/i915_lobf_info. [Jouni]
- Rebase on intel_alpm_source_supported() taking intel_dp and skip
  MST connectors as they have no fixed encoder.

[PATCH v7 06/20] drm/i915/alpm: Refactor Auxless wake time calculation

[Animesh Manna]

Divide the auxless wake time calculation in parts which will
help later to add Xe3p related modification.

v2: Refactor first existing calculation. [Jani]
v3: Cosmetic changes. [Jani, Suraj]
v4: Keep num_ml_phy_lock for readability and return the
    establishment period directly. [Jouni]

[PATCH v7 08/20] 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. Also use the wider
limit when validating the computed wake lines and for the safest params
fallback.

v2: Modify AUX_LESS_WAKE_TIME bitfield for xe3lpd. [Suraj]
v3: Separate out AUX_LESS_WAKE_TIME bitfield change into its own
patch. [Jouni]
v4: Use the wider bitfield limit in aux-less wake time computation
and safest params. [Jouni, sashiko]

[PATCH v7 09/20] drm/i915/alpm: table based establishment period

[Animesh Manna]

With LTTPRs present, the establishment period calculated by the formula
is shorter than the values tabulated in the DP2.1 VESA spec by roughly
one LFPS period per LTTPR, even when max silence and LFPS periods are
used. This has been observed to cause flip done timeouts during ALPM
testing on a setup with LTTPRs.

Use the establishment period from the VESA spec table for the listed
link rates with 1 to 6 LTTPRs. Fall back to the calculated value for
link rates not in the table, LTTPR counts beyond the table and when no
LTTPR is present, where the formula already matches the spec.

v2: Add check for negative error codes from drm_dp_lttpr_count(). [sashiko]
v3:
- Explain why the spec table is used instead of the formula. [Jouni]
- Drop the no-LTTPR row as the formula matches the spec there.
- Drop link rates without tabulated values and replace the link rate
  enum and switch with a port_clock based lookup table.

[PATCH v7 11/20] drm/i915/alpm: Modify LFPS cycle count for DP ALPM

[Animesh Manna]

For DP minimum LFPS count is set to minimum 16.

Also use the link symbol clock instead of the link rate when computing
the half LFPS cycle in symbols. Both are the same for 8b/10b, which was
the only case so far with eDP, but they differ for 128b/132b.

v2:
- Drop unneeded comment. [Jouni]
- Use intel_dp_link_symbol_clock() for half LFPS cycle calculation. [Jouni]

[PATCH v7 12/20] 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]

[PATCH v7 15/20] 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]
v3:
- Use intel_dp_link_symbol_clock(). [Jouni]
- Fix switch to active time which was 32 times too long as the symbol
  clock already accounts for the 32 bits per symbol. [sashiko]
- Round the switch to active time up to microseconds. [sashiko]
- Check the switch to active latency fits into ALPM_CTL2. [sashiko]

[PATCH v7 16/20] 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.

ALPM is possible if the sink supports AUX-wake or AUX-less ALPM. With
LTTPRs present only AUX-less ALPM is possible, so both the sink and the
LTTPRs must support AUX-less ALPM.

LOBF enable/disable are only called based on has_lobf in the crtc state,
which is computed using alpm_is_possible(), so drop the capability check
from there. This also avoids leaving ALPM_CTL enabled on hot-unplug, as
the sink capabilities are reset before LOBF is disabled.

v2: Drop DISPLAY_VER() check as intel_alpm_source_supported
already checking and populating dpcd info. [Jouni]
v3:
- Check ALPM capability bits of sink and LTTPR. [sashiko]
- Drop alpm_is_possible() check from LOBF enable/disable. [Jouni, sashiko]

[PATCH v7 17/20] 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. Report ALPM as not possible in intel_alpm_is_possible() for
external DP running at a UHBR rate on display version 35, so that ALPM
and the features relying on it are not enabled in that case. eDP is
excluded so eDP ALPM keeps working at any link rate.

v2:
- Move the check into intel_alpm_is_possible(). [Jouni]

[PATCH v7 18/20] drm/i915/alpm: Compute ALPM config before PSR config

[Animesh Manna]

The ALPM params are computed by alpm_config_valid() while computing the
PSR config and again by intel_alpm_lobf_compute_config() for LOBF.

Add intel_alpm_compute_config() which computes the ALPM params once
before the PSR config and records whether AUX wake and AUX-less ALPM
are possible in alpm_state.aux_wake_possible and
alpm_state.aux_less_possible. Do the LOBF compute from there as well.
alpm_config_valid() now uses these flags to choose between PSR, PSR2
and Panel Replay.

No functional change intended.

[PATCH v7 19/20] 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. It is set in one place, in the new
intel_alpm_compute_config_late(), once the final PSR, Panel Replay and
LOBF state is known:

 - eDP Panel Replay and PSR2 always use ALPM.
 - DP Panel Replay uses ALPM only if AUX-less ALPM is possible and its
   wake time fits, otherwise Panel Replay is used without ALPM.
 - Otherwise ALPM follows LOBF.

intel_alpm_compute_config_late() also does the late LOBF checks that
intel_alpm_lobf_compute_config_late() did before.

Use has_alpm in the ALPM configure and sink enable paths, and require
it in intel_alpm_is_aux_less() (renamed from
intel_alpm_is_alpm_aux_less()) so that AUX-less ALPM programming,
including the AS SDP part of PR_ALPM_CTL and the MAC transmit LFPS, is
skipped when ALPM is not used. Require the ALPM DPCD caps for AUX-less
ALPM on eDP as well.

v2:
- Set has_alpm in one place in intel_alpm_compute_config_late(). [Jouni]
- Don't let selective update overwrite has_alpm. [sashiko]
- Don't leave has_alpm set when PSR features are dropped late. [sashiko]
- Keep clearing the port ALPM registers when ALPM is not used. [sashiko]
- Require has_alpm for AUX-less ALPM programming. [sashiko]
- Keep ALPM enabled for PSR2 regardless of the ALPM DPCD caps.

[PATCH v7 20/20] drm/i915/dp: Enable AS SDP for DP Panel Replay with AUX-less ALPM

[Animesh Manna]

AS SDP for Panel Replay with AUX-less ALPM and the related
DP_FIXED_VTOTAL_AS_SDP_EN_IN_PR_ACTIVE setting are limited to eDP by
intel_psr_needs_alpm_aux_less(). DP Panel Replay can now use AUX-less
ALPM as well, so base these on the ALPM state instead.

has_alpm is decided only in the late compute config, after AS SDP has
been computed. Use alpm_state.aux_less_possible to decide whether AS
SDP is needed, and has_alpm for the link training DPCD setting, which
happens with the final state.

intel_psr_needs_alpm_aux_less() is now used only within intel_psr.c,
so make it static.

drm/i915/alpm: Half LFPS cycle calculation

This patch updates the LFPS cycle period minimum and maximum calculation for
DP2.1 ALPM by splitting it into HAS_LT_PHY() and non-LT-PHY helpers that check
whether the output type is eDP.

[Severity: High]
Can tlfps_cycle_min and tlfps_cycle_max be used uninitialized in
get_lfps_cycle_time()?

In get_lfps_cycle_time(), tlfps_cycle_min and tlfps_cycle_max are declared
without initialization and passed to get_lfps_period_min_max_time(). When
HAS_LT_PHY(display) is false, get_lfps_period_min_max_time() calls
lnl_get_lfps_period_min_max_time(), which only assigns *min and *max when
intel_crtc_has_type(crtc_state, INTEL_OUTPUT_EDP) is true.

For non-eDP outputs on !HAS_LT_PHY(display) platforms, *min and *max are
never written before get_lfps_cycle_time() computes:

	return tlfps_cycle_min +  (tlfps_cycle_max - tlfps_cycle_min) / 2;

In particular, get_establishment_period() calls get_lfps_cycle_time() when
lttpr_count > 0, which only occurs in the !intel_crtc_has_type(crtc_state,
INTEL_OUTPUT_EDP) branch:

drivers/gpu/drm/i915/display/intel_alpm.c:get_establishment_period() {
	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;

		lttpr_count = drm_dp_lttpr_count(intel_dp->lttpr_common_caps);
		...
	}
	...
	if (lttpr_count > 0) {
		/* tlw and tcs values are taken from DP2.1 spec */
		int tlw = 13000;
		int tcs = 10000;
		int tlfps_period = get_lfps_cycle_time(crtc_state);
		...
	}
}

Would this leave tlfps_cycle_min and tlfps_cycle_max uninitialized at
runtime for non-eDP DP outputs and trigger -Wmaybe-uninitialized or
-Wsometimes-uninitialized warnings during the build?

drm/i915/alpm: alpm_init() for DP2.1

This commit initializes ALPM for DP 2.1 on display version 35 and newer,
separating the ALPM mutex initialization from DPCD capability initialization
and checking source support instead of sink capabilities in
intel_alpm_disable().

[Severity: High]
Can replacing the intel_dp->alpm_dpcd check with
intel_alpm_source_supported(intel_dp) here cause intel_alpm_disable() to
modify ALPM_CTL on the wrong transcoder when ALPM was never configured on
intel_dp?

Because struct intel_digital_port is zero-allocated,
intel_dp->alpm.transcoder starts at 0 (TRANSCODER_A, rather than
INVALID_TRANSCODER), and intel_alpm_init() does not initialize it. Across
the driver, intel_dp->alpm.transcoder is only set in
intel_alpm_configure():

drivers/gpu/drm/i915/display/intel_alpm.c:intel_alpm_configure() {
	lnl_alpm_configure(intel_dp, crtc_state);
	intel_dp->alpm.transcoder = crtc_state->cpu_transcoder;
}

which is only called from intel_psr_enable_source() when
crtc_state->has_psr is true or from intel_alpm_lobf_enable() when
new_crtc_state->has_lobf is true.

However, intel_ddi_disable_dp() unconditionally calls
intel_alpm_disable(intel_dp) whenever any DP or eDP encoder is disabled:

drivers/gpu/drm/i915/display/intel_ddi.c:intel_ddi_disable_dp() {
	...
	intel_panel_unprepare(old_conn_state);
	intel_psr_disable(intel_dp, old_crtc_state);
	intel_alpm_disable(intel_dp);
	...
}

And intel_dp_short_pulse() also calls intel_alpm_disable(intel_dp) if
reading DP_RECEIVER_ALPM_STATUS fails or reports an error:

drivers/gpu/drm/i915/display/intel_dp.c:intel_dp_short_pulse() {
	...
	if (intel_alpm_get_error(intel_dp)) {
		intel_alpm_disable(intel_dp);
		intel_dp->alpm.sink_alpm_error = true;
	}
	...
}

Previously, !intel_dp->alpm_dpcd caused intel_alpm_disable() to return
early for external DP connectors and eDP panels without ALPM support. With
this change, if an external DP connector on DISPLAY_VER(display) >= 35 (or
an eDP connector on DISPLAY_VER(display) >= 20) is enabled on
TRANSCODER_B/C/D without PSR, Panel Replay, or LOBF, intel_alpm_configure()
is never called and intel_dp->alpm.transcoder remains TRANSCODER_A (or a
stale transcoder from a previous modeset).

When that connector is later disabled or hits the short HPD pulse error
path, intel_alpm_disable() will lock that connector's intel_dp->alpm.lock
and clear ALPM_CTL_ALPM_ENABLE | ALPM_CTL_LOBF_ENABLE in
ALPM_CTL(display, TRANSCODER_A). If TRANSCODER_A is active on another
connector (such as eDP on Pipe A), this races with Pipe A and disables its
active ALPM/LOBF state; if TRANSCODER_A's power well is off, it triggers an
unclaimed MMIO register access.

Should intel_dp->alpm.transcoder be initialized to INVALID_TRANSCODER in
intel_alpm_init(), reset to INVALID_TRANSCODER in intel_alpm_disable(), and
checked for INVALID_TRANSCODER before accessing ALPM_CTL()?

Author: Animesh Manna <animesh.manna@intel.com>

drm/i915/alpm: Replace is_edp() with alpm_is_possible()

This commit introduces intel_alpm_is_possible() to check ALPM capability
from DPCD and LTTPR info instead of checking intel_dp_is_edp() in
intel_alpm_lobf_compute_config(). It also removes the intel_dp_is_edp()
checks from intel_alpm_lobf_enable() and intel_alpm_lobf_disable().

[Severity: High]
Can removing the intel_dp_is_edp() check in intel_alpm_lobf_disable() cause
mutex_lock(&intel_dp->alpm.lock) to be called on an uninitialized mutex?

In drivers/gpu/drm/i915/display/intel_alpm.c, intel_alpm_init() only
initializes alpm.lock when intel_alpm_source_supported(intel_dp) is true:

void intel_alpm_init(struct intel_dp *intel_dp)
{
	if (!intel_alpm_source_supported(intel_dp))
		return;

	mutex_init(&intel_dp->alpm.lock);
}

On platforms with DISPLAY_VER between 20 and 34, intel_alpm_source_supported()
is only true for eDP encoders, so non-eDP DP encoders leave alpm.lock
uninitialized.

In drivers/gpu/drm/i915/display/intel_display.c, intel_pre_plane_update()
checks whether LOBF is being disabled via intel_crtc_lobf_disabling(), which
inspects old_crtc_state->has_lobf, but then passes new_crtc_state to
intel_alpm_lobf_disable():

	if (intel_crtc_lobf_disabling(old_crtc_state, new_crtc_state))
		intel_alpm_lobf_disable(new_crtc_state);

If a CRTC with LOBF active on an eDP encoder (old_crtc_state->has_lobf is
true) is switched in an atomic modeset to a non-eDP DP encoder
(new_crtc_state->has_lobf is false), intel_alpm_lobf_disable() iterates over
new_crtc_state->uapi.encoder_mask and calls mutex_lock(&intel_dp->alpm.lock)
on the non-eDP encoder whose mutex was never initialized.

Additionally, because intel_alpm_lobf_disable() inspects new_crtc_state
rather than old_crtc_state, disabling a CRTC by detaching its connector
(leaving new_crtc_state->uapi.encoder_mask empty) skips the loop and leaves
ALPM_CTL enabled, or on DISPLAY_VER >= 35 locks the new encoder's alpm.lock
instead of the old encoder's.

Should intel_pre_plane_update() pass old_crtc_state to
intel_alpm_lobf_disable(const struct intel_crtc_state *old_crtc_state) so it
operates on the encoder and transcoder where LOBF was previously enabled?

drm/i915/alpm: Introduce has_alpm to decouple from pr/psr2/lobf

This patch introduces crtc_state->has_alpm in intel_alpm_compute_config_late()
to decouple ALPM enablement from Panel Replay, PSR2, and LOBF so that DP 2.1
Panel Replay can operate with or without ALPM.

[Severity: Medium]
Can intel_psr_wake_lines_fit_into_vblank() fail to enable crtc_state->has_alpm
on external DP Panel Replay because intel_psr_min_guardband() does not reserve
aux_less_wake_lines for non-eDP outputs?

On DISPLAY_VER(display) >= 35, intel_vrr_always_use_vrr_tg() and
intel_vrr_use_optimized_guardband() are used, so before
intel_dp_compute_config_late() -> intel_alpm_compute_config_late() runs,
intel_crtc_compute_config() -> intel_vrr_compute_guardband() ->
intel_vrr_compute_optimized_guardband() computes crtc_state->vrr.guardband and
adjusts crtc_vblank_start:

drivers/gpu/drm/i915/display/intel_vrr.c:intel_vrr_compute_optimized_guardband() {
	...
	if (intel_crtc_has_dp_encoder(crtc_state)) {
		guardband = max(guardband, intel_psr_min_guardband(crtc_state));
		guardband = max(guardband, intel_dp_sdp_min_guardband(crtc_state, true));
		guardband = max(guardband, intel_alpm_lobf_min_guardband(crtc_state));
	}
	...
}

drivers/gpu/drm/i915/display/intel_vrr.c:intel_vrr_compute_guardband() {
	...
	if (intel_vrr_always_use_vrr_tg(display)) {
		adjusted_mode->crtc_vblank_start  =
			adjusted_mode->crtc_vtotal - crtc_state->vrr.guardband;
	...
}

However, intel_psr_min_guardband() in drivers/gpu/drm/i915/display/intel_psr.c
currently skips non-eDP encoders:

drivers/gpu/drm/i915/display/intel_psr.c:intel_psr_min_guardband() {
	...
	if (!intel_crtc_has_type(crtc_state, INTEL_OUTPUT_EDP))
		return 0;

	if (crtc_state->has_panel_replay)
		wake_lines = crtc_state->alpm_state.aux_less_wake_lines;
	...
}

When crtc_state->has_lobf is false (for example, when !intel_dp->as_sdp_supported,
intel_dp->alpm.lobf_disable_debug is set, or intel_dp->alpm.sink_alpm_error is
set), intel_alpm_lobf_min_guardband() also returns 0. That shrinks
crtc_state->vrr.guardband (and therefore intel_crtc_vblank_length(crtc_state))
to the prefill/SDP guardband, which can be smaller than aux_less_wake_lines
even when the mode's full vblank is large enough.

Should intel_psr_min_guardband() also reserve aux_less_wake_lines for external
DP Panel Replay when crtc_state->alpm_state.aux_less_possible is true?

[Severity: High]
With crtc_state->has_alpm now enabling ALPM in lnl_alpm_configure() and
intel_alpm_enable_sink() for non-eDP Panel Replay, can ALPM remain enabled on
both the source and sink when DP Panel Replay is later disabled or reconfigured
to !crtc_state->has_alpm?

In drivers/gpu/drm/i915/display/intel_psr.c, intel_psr_disable_locked() still
guards intel_alpm_disable() with intel_dp_is_edp() and only clears
DP_RECEIVER_ALPM_CONFIG when !intel_dp->psr.panel_replay_enabled:

drivers/gpu/drm/i915/display/intel_psr.c:intel_psr_disable_locked() {
	...
	if (intel_dp->psr.panel_replay_enabled && intel_dp_is_edp(intel_dp))
		intel_alpm_disable(intel_dp);

	/* Disable PSR on Sink */
	if (!intel_dp->psr.panel_replay_enabled) {
		drm_dp_dpcd_write_byte(&intel_dp->aux, DP_PSR_EN_CFG, 0);

		if (intel_dp->psr.sel_update_enabled)
			drm_dp_dpcd_write_byte(&intel_dp->aux,
					       DP_RECEIVER_ALPM_CONFIG, 0);
	}
}

When external DP Panel Replay (!intel_dp_is_edp(intel_dp)) with ALPM is
disabled without a full encoder disable (such as in
intel_psr_pre_plane_update() when all planes become inactive, during fastsets,
or on a sink error in intel_psr_short_pulse()), intel_alpm_disable() is skipped
and ALPM_CTL_ALPM_ENABLE stays set in ALPM_CTL. Subsequent re-enables in
intel_psr_post_plane_update() -> intel_psr_enable_locked() ->
intel_psr_enable_source() -> intel_alpm_configure() -> lnl_alpm_configure()
then rewrite ALPM_CTL, ALPM_CTL2, and PR_ALPM_CTL while ALPM is still enabled
in hardware.

Furthermore, because neither intel_psr_disable_locked() nor
intel_alpm_enable_sink() clears DP_RECEIVER_ALPM_CONFIG for Panel Replay when
transitioning to !crtc_state->has_alpm, won't DP_RECEIVER_ALPM_CONFIG remain
enabled on the sink (and ALPM_CTL remain enabled on the source across a
fastset) if a subsequent commit runs Panel Replay without ALPM?
