v2: Send the two related patches together as a series, as requested
by Jani. No code changes from v1.
This series fixes two related issues in MST payload bandwidth
accounting that together caused 4K@60Hz to fail alongside two
1080p@60Hz displays in a 3-display MST daisy-chain topology
(PS8650 hub -> ViewSonic VP2468 x2 -> Lenovo Pro 27UD-10).
Patch 1 fixes the PBN value passed in the ALLOCATE_PAYLOAD sideband
request. The driver was using a TU-aligned PBN (e.g. 537) instead of
the actual video stream bandwidth (e.g. 496 for 1080p@59.94Hz),
inflating the requested PBN and causing -ENOSPC failures for
configurations that should fit within the available link bandwidth.
Patch 2 tracks the allocated_pbn returned in the ALLOCATE_PAYLOAD
reply, and uses it alongside @pbn for bandwidth limit checks. This
ensures that any per-hop capacity constraints from intermediate MST
branches are correctly reflected in the source-side bandwidth check.

When computing the number of time slots for an MST stream,
intel_dp_mtp_tu_compute_config() was passing the TU-aligned PBN value
to drm_dp_atomic_find_time_slots() instead of the actual video
bandwidth PBN.
The aligned PBN is computed by rounding up the raw video bandwidth to
the nearest TU boundary and aligning to the hardware TU granularity
(4 / lane_count). This inflated PBN is then used as the requested PBN
in the ALLOCATE_PAYLOAD sideband message, causing the MST core's
bandwidth check in drm_dp_mst_atomic_check_port_bw_limit() to
incorrectly reject configurations that should fit within the available
link bandwidth.
Per DP v2.1b Section 2.6.4.1, the PBN in an ALLOCATE_PAYLOAD request
represents the video stream bandwidth and is independent of the source
TX link rate. The same video stream should result in the same PBN value
regardless of the link rate used on the source side. Passing the
TU-aligned PBN violates this requirement, as it incorporates link-rate-
specific TU granularity into the payload bandwidth value.
This was observed in a 3-display MST daisy-chain topology (PS8650 MST
hub → ViewSonic VP2468 × 2 → Lenovo Pro 27UD-10) where switching
Lenovo to 4K@60Hz failed with -ENOSPC despite the actual video
bandwidth fitting within the DFP link capacity. The inflated PBN of
the VP2468 streams (537 instead of the correct 532 for 1920x1080@60Hz)
consumed excess slots, leaving insufficient room for the 4K@60Hz stream.
Fix this by separating raw_pbn (the actual video bandwidth used for
payload allocation and ALLOCATE_PAYLOAD) from the aligned pbn (used
only for TU hardware programming). Pass raw_pbn to
drm_dp_atomic_find_time_slots() so that bandwidth accounting in the
MST core reflects the true stream requirements.
Depends-on: <20260908132844.2309047-1-xiaolu.xie@intel.com>
("drm/dp/mst: track allocated_pbn from ALLOCATE_PAYLOAD reply")
The companion patch above tracks the allocated_pbn returned in the
ALLOCATE_PAYLOAD reply from the branch device. Together with this fix,
the correct raw_pbn is used as the requested PBN in the
ALLOCATE_PAYLOAD request, and the allocated_pbn from the reply is used
for bandwidth limit checks. This pairing ensures that both the request
and the check accurately reflect the actual video stream bandwidth
and any per-hop capacity constraints along the MST path.

The DP MST ALLOCATE_PAYLOAD sideband message returns the payload bandwidth actually allocated by the branch in the allocated_pbn field of the down-reply. That value may differ from the requested PBN when an intermediate branch applies its own constraints, so the source should keep track of it instead of only relying on the local request.
Store the allocated_pbn returned by the ALLOCATE_PAYLOAD down-reply sideband message and use the larger of requested PBN and allocated PBN for the MST bandwidth limit checks. Also carry the value across dependent atomic commits and clear it when releasing the payload, matching the lifetime of the remote allocation state.

I bounced this series to intel-xe@lists.freedesktop.org as well, since
the display code is shared with xe, and we want to run xe CI on it too.
MAINTAINERS should indicate this. For future reference, please send
Intel display patches to both intel-xe and intel-gfx mailing lists.
Thanks,
Jani.

Author: Xiao Lu <xiaolu.xie@intel.com>
Subject: drm/i915/dp: fix PBN in ALLOCATE_PAYLOAD request to use actual video bandwidth
This commit modifies intel_dp_mtp_tu_compute_config() to separate the actual
video bandwidth (raw_pbn) from the aligned PBN used for hardware TU
programming. It passes raw_pbn to drm_dp_atomic_find_time_slots() so that the
MST core allocates payload bandwidth reflecting true stream requirements rather
than incorporating link-rate-specific TU granularity.

[Severity: High]
Does this cause a timeslot accounting mismatch and a kernel warning?
By passing raw_pbn to drm_dp_atomic_find_time_slots() in
intel_dp_mtp_tu_compute_config(), the function calculates and returns an
unaligned VCPI timeslot allocation. However, the Intel TX hardware requires
timeslots to be aligned (e.g., to a 4-slot boundary for a 1-lane link).
Because the returned slots is unaligned, it diverges from the hardware-aligned
dp_m_n.tu. This leads to two issues:
1. The boundary check immediately following this call:
if (slots > mst_state->total_avail_slots)
slots = -EINVAL;
incorrectly uses the unaligned slots value rather than checking the final
aligned remote_tu that is actually programmed into the hardware. This might
bypass the availability check for streams that exceed link capacity when
aligned.
2. The assertion further down in the function:
drm_WARN_ON(display->drm, slots != crtc_state->dp_m_n.tu);
will falsely and reliably trigger a kernel stack trace on any successful
modeset where alignment padding was applied (like on a 1-lane or 2-lane link
where 4 / lane_count alignment changes the raw TU count).
Additionally, this mismatch between the downstream branch device's DPCD
payload table (receiving the unaligned VCPI slot count) and the Intel TX
(transmitting the padded TU count) violates Bspec synchronization requirements
and risks payload corruption.

drm/dp_mst: Track allocated_pbn from ALLOCATE_PAYLOAD down-reply
This commit stores the allocated_pbn returned by the ALLOCATE_PAYLOAD
down-reply sideband message. It uses the larger of requested PBN and
allocated PBN for the MST bandwidth limit checks, carrying the value across
dependent atomic commits.

[Severity: High]
Is it safe to write to the active atomic state payload from an asynchronous
worker here without modeset locks?
If drm_dp_add_payload_part2() locklessly mutates allocated_pbn concurrently
with drm_dp_mst_duplicate_state(), could this result in a data race?
[Severity: High]
Is this untrusted 16-bit value from the branch device saved into the payload
state here without bounds checking?
If a malicious or malfunctioning branch device replies to the
ALLOCATE_PAYLOAD message with a spoofed allocated_pbn value (e.g., 65535),
could it be stored directly without validation?

Could this unconditional restore overwrite the 0 set by
drm_dp_atomic_find_time_slots() during the atomic check phase?
If it does, could it inflate the perceived bandwidth for concurrent checks?

[Severity: High]
Does evaluating this max() with a potentially stale or artificially inflated
value concurrently produce incorrect bandwidth checks?
If so, could it cause spurious -ENOSPC failures in bandwidth validation,
causing display configurations to fail randomly?
Also, if a maliciously huge value was evaluated here, could it force
pbn_used > port->full_pbn, failing the check?
Since the topology check iterates over all payloads, could this permanently
prevent any future display configurations on this topology?

Use the raw video PBN in ALLOCATE_PAYLOAD requests while keeping the
TU-aligned PBN for source hardware programming. Also track the PBN
actually allocated by downstream branches and use it in later bandwidth
checks.
The series was tested with a three-display PS8650 MST daisy chain.
Changes in v3:
- Preserve allocated_pbn when recalculating an active payload; clear it
only when releasing the payload.
- Patch 1 is unchanged.

When computing the number of time slots for an MST stream,
intel_dp_mtp_tu_compute_config() was passing the TU-aligned PBN value
to drm_dp_atomic_find_time_slots() instead of the actual video
bandwidth PBN.
The aligned PBN is computed by rounding up the raw video bandwidth to
the nearest TU boundary and aligning to the hardware TU granularity
(4 / lane_count). This inflated PBN is then used as the requested PBN
in the ALLOCATE_PAYLOAD sideband message, causing the MST core's
bandwidth check in drm_dp_mst_atomic_check_port_bw_limit() to
incorrectly reject configurations that should fit within the available
link bandwidth.
Per DP v2.1b Section 2.6.4.1, the PBN in an ALLOCATE_PAYLOAD request
represents the video stream bandwidth and is independent of the source
TX link rate. The same video stream should result in the same PBN value
regardless of the link rate used on the source side. Passing the
TU-aligned PBN violates this requirement, as it incorporates link-rate-
specific TU granularity into the payload bandwidth value.
This was observed in a 3-display MST daisy-chain topology (PS8650 MST
hub → ViewSonic VP2468 × 2 → Lenovo Pro 27UD-10) where switching
Lenovo to 4K@60Hz failed with -ENOSPC despite the actual video
bandwidth fitting within the DFP link capacity. The inflated PBN of
the VP2468 streams (537 instead of the correct 532 for 1920x1080@60Hz)
consumed excess slots, leaving insufficient room for the 4K@60Hz stream.
Fix this by separating raw_pbn (the actual video bandwidth used for
payload allocation and ALLOCATE_PAYLOAD) from the aligned pbn (used
only for TU hardware programming). Pass raw_pbn to
drm_dp_atomic_find_time_slots() so that bandwidth accounting in the
MST core reflects the true stream requirements.
Depends-on: <20260908132844.2309047-1-xiaolu.xie@intel.com>
("drm/dp/mst: track allocated_pbn from ALLOCATE_PAYLOAD reply")
The companion patch above tracks the allocated_pbn returned in the
ALLOCATE_PAYLOAD reply from the branch device. Together with this fix,
the correct raw_pbn is used as the requested PBN in the
ALLOCATE_PAYLOAD request, and the allocated_pbn from the reply is used
for bandwidth limit checks. This pairing ensures that both the request
and the check accurately reflect the actual video stream bandwidth
and any per-hop capacity constraints along the MST path.

The ALLOCATE_PAYLOAD reply may report a larger PBN than requested
when an intermediate branch applies its own constraints.
Store the reported PBN and use the larger of requested and allocated
PBN for bandwidth checks. Preserve it when recalculating time slots,
since clearing it there makes the next atomic check underestimate
active payloads. Clear it only when releasing the payload.

drm/i915/dp: fix PBN in ALLOCATE_PAYLOAD request to use actual video bandwidth
This commit updates intel_dp_mtp_tu_compute_config() to separate the raw
video bandwidth PBN from the aligned hardware TU PBN. The raw PBN is now
passed to drm_dp_atomic_find_time_slots() to fix payload allocation
rejections.

[Severity: High]
Does this cause a mismatch in the programmed VCPI payload size?
By passing the unaligned raw_pbn here, the DRM core calculates an unaligned
VCPI timeslot allocation that is programmed into the downstream branch
device.
Since the i915 hardware transmitter still expects the lane-count aligned
remote_tu, the source hardware and branch device will now have mismatched
payload sizes. Can this mismatch break DP MST frame synchronization and
cause data drops or display corruption?
Additionally, this mismatch appears to deterministically trigger an existing
validation warning later in intel_dp_mtp_tu_compute_config():
if (slots >= 0) {
drm_WARN_ON(display->drm, slots != crtc_state->dp_m_n.tu);
break;
}
Will this unconditionally fire during modesets where the required timeslots
are not a multiple of the lane count?

[Severity: High]
Does this limit check accurately reflect the required slots?
This check now validates the unaligned slots. Because the source hardware
uses remote_tu (which is aligned and thus potentially larger), could the
hardware's aligned timeslots exceed the physical 64-slot limit even if
the unaligned slots pass this check?

drm/dp_mst: Track allocated_pbn from ALLOCATE_PAYLOAD down-reply
This commit stores the reported PBN from an ALLOCATE_PAYLOAD reply. It uses
the larger of the requested and allocated PBN for bandwidth checks to account
for constraints applied by intermediate branches along the path.

[Severity: High]
Can this lockless write to payload->allocated_pbn race with an atomic check?
If a non-blocking atomic commit is executing asynchronously, it receives the
ALLOCATE_PAYLOAD reply and drm_dp_payload_send_msg() updates allocated_pbn
without locks. Concurrently, if userspace initiates a new atomic check,
drm_dp_mst_duplicate_state() will copy the payload struct via kmemdup().
Could this result in the atomic check reading a torn or stale value when
evaluating max(payload->pbn, payload->allocated_pbn) in
drm_dp_mst_atomic_check_port_bw_limit(), potentially bypassing bandwidth
constraints?

[Severity: Medium]
Does this properly handle payloads that shrink in size?
Since payload->allocated_pbn is only cleared here when releasing the payload
entirely (during a full deletion), what happens if a commit simply shrinks an
existing payload (for example, switching to a smaller display mode on the
same CRTC)?
In that scenario, drm_dp_atomic_release_time_slots() skips active CRTCs,
meaning allocated_pbn remains at its old, larger value. When the new
bandwidth is checked, max(payload->pbn, payload->allocated_pbn) in
drm_dp_mst_atomic_check_port_bw_limit() would yield the old larger value,
which could falsely prevent the freed bandwidth from being reallocated to
other displays.
