2024-02-28drm/dp: Don't attempt AUX transfers when eDP panels are not poweredDouglas Anderson
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.

2024-02-27drm/i915/dp: Handle DP tunnel IRQsImre Deak
Handle DP tunnel IRQs a sink (or rather a BW management component like the Thunderbolt Connection Manager) raises to signal the completion of a BW request by the driver, or to signal any state change related to the link BW.

2024-02-27drm/dp: Add support for DP tunnelingImre Deak
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.

2023-11-08drm/dp: Add helpers to calculate the link BW overheadImre Deak
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.

2023-11-08drm/dp_mst: Fix fractional DSC bpp handlingVille Syrjälä
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.

2023-09-08drm/mst: Refactor the flow for payload allocation/removementWayne Lin
[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'.

2023-06-15drm/dp_mst: Clear MSG_RDY flag before sending new messageWayne Lin
[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>
