drm/dp: Don't attempt AUX transfers when eDP panels are not powered
If an eDP panel is not powered on then any attempts to talk to it over the DP AUX channel will timeout. Unfortunately these attempts may be quite slow. Userspace can initiate these attempts either via a /dev/drm_dp_auxN device or via the created i2c device. Making the DP AUX drivers timeout faster is a difficult proposition. In theory we could just poll the panel's HPD line in the AUX transfer function and immediately return an error there. However, this is easier said than done. For one thing, there's no hard requirement to hook the HPD line up for eDP panels and it's OK to just delay a fixed amount. For another thing, the HPD line may not be fast to probe. On parade-ps8640 we need to wait for the bridge chip's firmware to boot before we can get the HPD line and this is a slow process. The fact that the transfers are taking so long to timeout is causing real problems. The open source fwupd daemon sometimes scans DP busses looking for devices whose firmware need updating. If it happens to scan while a panel is turned off this scan can take a long time. The fwupd daemon could try to be smarter and only scan when eDP panels are turned on, but we can also improve the behavior in the kernel. Let's let eDP panels drivers specify that a panel is turned off and then modify the common AUX transfer code not to attempt a transfer in this case.

drm/dp: Add support for DP tunneling
Add support for Display Port tunneling. For now this includes the support for Bandwidth Allocation Mode (BWA), leaving adding Panel Replay support for later. BWA allows using displays that share the same (Thunderbolt) link with their maximum resolution. Atm, this may not be possible due to the coarse granularity of partitioning the link BW among the displays on the link: the BW allocation policy is in a SW/FW/HW component on the link (on Thunderbolt it's the SW or FW Connection Manager), independent of the driver. This policy will set the DPRX maximum rate and lane count DPCD registers the GFX driver will see (0x00000, 0x00001, 0x02200, 0x02201) based on the available link BW. The granularity of the current BW allocation policy is coarse, based on the required link rate in the 1.62Gbs..8.1Gbps range and it may prevent using higher resolutions all together: the display connected first will get a share of the link BW which corresponds to its full DPRX capability (regardless of the actual mode it uses). A subsequent display connected will only get the remaining BW, which could be well below its full capability. BWA solves the above coarse granularity (reducing it to a 250Mbs..1Gps range) and first-come/first-served issues by letting the driver request the BW for each display on a link which reflects the actual modes the displays use. This patch adds the DRM core helper functions, while a follow-up change in the patchset takes them into use in the i915 driver. v2: - Fix prepare_to_wait vs. wake-up cond check order in allocate_tunnel_bw(). (Ville) - Move tunnel==NULL checks from callers in drivers to here. (Ville) - Avoid var inits in declaration blocks that can fail or have side-effects. (Ville) - Use u8 for driver and group IDs. (Ville) - Simplify API removing drm_dp_tunnel_get/put_untracked(). (Ville) - Reuse str_yes_no() instead of a local yes_no_chr(). (Ville) - s/drm_dp_tunnel_atomic_clear_state()/free_tunnel_state() and unexport the function. (Ville) - s/clear_tunnel_group_state()/free_group_state() and move kfree() to this function. (Ville) - Add separate group_free_bw() helper and describe what the tunnel estimated BW includes. (Ville) - Improve help text for CONFIG_DRM_DISPLAY_DP_TUNNEL. (Ville) - Add code comment explaining the purpose of DPCD reg read helpers. (Ville) - Add code comment describing the tunnel group name prefix format. (Ville) - Report the allocated BW as undetermined until the first allocation request. - Skip allocation requests matching the previous request. - Clear any stale BW request status flags before a new request. - Add missing error return check of drm_dp_tunnel_atomic_get_group_state() in drm_dp_tunnel_atomic_set_stream_bw(). - Add drm_dp_tunnel_get_allocated_bw(). - s/drm_dp_tunnel_atomic_get_tunnel_bw/drm_dp_tunnel_atomic_get_required_bw - Fix return value description in function doc of drm_dp_tunnel_detect(). - Add function documentation to all exported functions. v3: - Improve grouping of fields in drm_dp_tunnel_group struct. (Uma) - Fix validating the BW granularity DPCD reg value. (Uma) - Document return value of check_and_clear_status_change(). (Uma) - Fix resetting drm_dp_tunnel_ref::tunnel in drm_dp_tunnel_ref_put().

drm/dp: Add helpers to calculate the link BW overhead
Add helpers drivers can use to calculate the BW allocation overhead -
due to SSC, FEC, DSC and data alignment on symbol cycles - and the
channel coding efficiency - due to the 8b/10b, 128b/132b encoding. On
128b/132b links the FEC overhead is part of the coding efficiency, so
not accounted for in the BW allocation overhead.
The drivers can use these functions to calculate a ratio, controlling
the stream symbol insertion rate of the source device in each SST TU
or MST MTP frame. Drivers can calculate this
m/n = (pixel_data_rate * drm_dp_bw_overhead()) /
(link_data_rate * drm_dp_bw_channel_coding_efficiency())
ratio for a given link and pixel stream and with that the
slots_per_mtp = CEIL(64 * m / n)
allocated slots per MTP for the stream in a link frame and with
that the
pbn = slots_per_mtp * drm_mst_get_pbn_divider()
allocated PBNs for the stream on the MST link path.
Take drm_dp_bw_overhead() into use in drm_dp_calc_pbn_mode(), for
drivers calculating the PBN value directly.
v2:
- Add dockbook description to drm_dp_bw_channel_coding_efficiency().
(LKP).
- Clarify the way m/n ratio is calculated in the commit log.
v3:
- Fix compile breakage for !CONFIG_BACKLIGHT_CLASS_DEVICE. (LKP)
- Account for FEC_PM overhead (+ 0.0015625 %), add comment
with the formula to calculate the total FEC overhead. (Ville)
v4:
- Rename DRM_DP_OVERHEAD_SSC to DRM_DP_OVERHEAD_SSC_REF_CLK. (Ville)
v5:
- Clarify in the commit log what MTP means.
- Simplify the commit log's formula to calculate PBN.

drm/dp_mst: Allow DSC in any Synaptics last branch device
The Synaptics MST branch devices support DSC decompression on all their output ports, provided that they are last branch devices (with their output ports connected to the sinks). The Thinkpad 40B0 TBT dock for instance has two such branch devices, a secondary one connected to one of the output ports of the primary; hence the decompression needs to be enabled in both branch devices to enable decompression for all the sinks. Based on the above add support for enabling decompression in last Synaptics branch devices.

drm/dp_mst: Swap the order of checking root vs. non-root port BW limitations
drm_dp_mst_atomic_check_mgr() should check for BW limitation starting from sink ports continuing towards the root port, so that drivers can use the @failing_port returned to resolve a BW overallocation in an ideal way. For instance from streams A,B,C in a topology A,B going through @failing_port and C not going through it, a BW overallocation of A,B due to a limit of the port must be resolved first before considering the limits of other ports closer to the root port. This way can avoid reducing the BW of stream C unnecessarily due to a BW limit closer to the root port. Based on the above swap the order of the BW check for the root port and the check for all the ports downstream of it (the latter going through the topology already in the sink->root port direction).

drm/dp_mst: Fix fractional DSC bpp handling
The current code does '(bpp << 4) / 16' in the MST PBN
calculation, but that is just the same as 'bpp' so the
DSC codepath achieves absolutely nothing. Fix it up so that
the fractional part of the bpp value is actually used instead
of truncated away. 64*1006 has enough zero lsbs that we can
just shift that down in the dividend and thus still manage
to stick to a 32bit divisor.
And while touching this, let's just make the whole thing more
straightforward by making the passed in bpp value .4 binary
fixed point always, instead of having to pass in different
things based on whether DSC is enabled or not.
v2:
- Fix DSC kunit test cases.

drm/mst: Refactor the flow for payload allocation/removement
[Why]
Today, the allocation/deallocation steps and status is a bit unclear.
For instance, payload->vc_start_slot = -1 stands for "the failure of
updating DPCD payload ID table" and can also represent as "payload is not
allocated yet". These two cases should be handled differently and hence
better to distinguish them for better understanding.
[How]
Define enumeration - ALLOCATION_LOCAL, ALLOCATION_DFP and ALLOCATION_REMOTE
to distinguish different allocation status. Adjust the code to handle
different status accordingly for better understanding the sequence of
payload allocation and payload removement.
For payload creation, the procedure should look like this:
DRM part 1:
* step 1 - update sw mst mgr variables to add a new payload
* step 2 - add payload at immediate DFP DPCD payload table
Driver:
* Add new payload in HW and sync up with DFP by sending ACT
DRM Part 2:
* Send ALLOCATE_PAYLOAD sideband message to allocate bandwidth along the
virtual channel.
And as for payload removement, the procedure should look like this:
DRM part 1:
* step 1 - Send ALLOCATE_PAYLOAD sideband message to release bandwidth
along the virtual channel
* step 2 - Clear payload allocation at immediate DFP DPCD payload table
Driver:
* Remove the payload in HW and sync up with DFP by sending ACT
DRM part 2:
* update sw mst mgr variables to remove the payload
Note that it's fine to fail when communicate with the branch device
connected at immediate downstrean-facing port, but updating variables of
SW mst mgr and HW configuration should be conducted anyway. That's because
it's under commit_tail and we need to complete the HW programming.
Changes since v1:
* Remove the set but not use variable 'old_payload' in function
'nv50_msto_prepare'. Catched by kernel test robot <lkp@intel.com>

drm/cec: add drm_dp_cec_attach() as the non-edid version of set edid
Connectors have source physical address available in display info. There's no need to parse the EDID again for this. Add drm_dp_cec_attach() to do this. Seems like the set_edid/unset_edid naming is a bit specific now that there's no need to pass the EDID at all, so aim for attach/detach going forward. v2: Fix the embarrashing build failures Cc: Hans Verkuil <hverkuil-cisco@xs4all.nl> Cc: linux-media@vger.kernel.org Signed-off-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Acked-by: Maxime Ripard <mripard@kernel.org> Link: https://patchwork.freedesktop.org/patch/msgid/20230825130120.1250089-1-jani.nikula@intel.com |

drm/display/dp: Assume 8 bpc support when DSC is supported
As per DP v1.4, a DP DSC Sink device shall support 8bpc in DPCD 6Ah. Apparently some panels that do support DSC, are not setting the bit for 8bpc. So always assume 8bpc support by DSC decoder, when DSC is claimed to be supported. v2: Use helper to get check dsc support. (Ankit) v3: Fix styling and other typos.

drm/sysfs: rename drm_sysfs_connector_status_event()
Rename drm_sysfs_connector_status_event() to drm_sysfs_connector_property_event(). Indeed, "status" is a bit vague: it can easily be confused with the connected/disconnected status of the connector. This function has nothing to do with connected/disconnected: it merely sends a notification that a connector's property has changed (e.g. HDCP, privacy screen, etc).

drm: use mgr->dev in drm_dbg_kms in drm_dp_add_payload_part2
I've been experiencing some intermittent crashes down in the display
driver code. The symptoms are ususally a line like this in dmesg:
amdgpu 0000:30:00.0: [drm] Failed to create MST payload for port 000000006d3a3885: -5
...followed by an Oops due to a NULL pointer dereference.
Switch to using mgr->dev instead of state->dev since "state" can be
NULL in some cases.

drm/dp_mst: Clear MSG_RDY flag before sending new message
[Why] The sequence for collecting down_reply from source perspective should be: Request_n->repeat (get partial reply of Request_n->clear message ready flag to ack DPRX that the message is received) till all partial replies for Request_n are received->new Request_n+1. Now there is chance that drm_dp_mst_hpd_irq() will fire new down request in the tx queue when the down reply is incomplete. Source is restricted to generate interveleaved message transactions so we should avoid it. Also, while assembling partial reply packets, reading out DPCD DOWN_REP Sideband MSG buffer + clearing DOWN_REP_MSG_RDY flag should be wrapped up as a complete operation for reading out a reply packet. Kicking off a new request before clearing DOWN_REP_MSG_RDY flag might be risky. e.g. If the reply of the new request has overwritten the DPRX DOWN_REP Sideband MSG buffer before source writing one to clear DOWN_REP_MSG_RDY flag, source then unintentionally flushes the reply for the new request. Should handle the up request in the same way. [How] Separete drm_dp_mst_hpd_irq() into 2 steps. After acking the MST IRQ event, driver calls drm_dp_mst_hpd_irq_send_new_request() and might trigger drm_dp_mst_kick_tx() only when there is no on going message transaction. Changes since v1: * Reworked on review comments received -> Adjust the fix to let driver explicitly kick off new down request when mst irq event is handled and acked -> Adjust the commit message Changes since v2: * Adjust the commit message * Adjust the naming of the divided 2 functions and add a new input parameter "ack". * Adjust code flow as per review comments. Changes since v3: * Update the function description of drm_dp_mst_hpd_irq_handle_event Changes since v4: * Change ack of drm_dp_mst_hpd_irq_handle_event() to be an array align the size of esi[] Signed-off-by: Wayne Lin <Wayne.Lin@amd.com> Reviewed-by: Lyude Paul <lyude@redhat.com> Acked-by: Jani Nikula <jani.nikula@intel.com> Cc: stable@vger.kernel.org Signed-off-by: Alex Deucher <alexander.deucher@amd.com> |

drm/display/dp_mst: convert to struct drm_edid
Convert the topology manager to use struct drm_edid, add drm_dp_mst_edid_read() that returns drm_edid, and rewrite the old drm_dp_mst_get_edid() to use it. Note that the old drm_get_edid() ended up calling drm_connector_update_edid_property(). This responsibility is now deferred to drivers, which all do it anyway after calling drm_dp_mst_edid_read() or drm_dp_mst_get_edid().
