2024-05-28drm/connector: hdmi: Add Infoframes generationMaxime Ripard1-0/+6
Infoframes in KMS is usually handled by a bunch of low-level helpers that require quite some boilerplate for drivers. This leads to discrepancies with how drivers generate them, and which are actually sent. Now that we have everything needed to generate them in the HDMI connector state, we can generate them in our common logic so that drivers can simply reuse what we precomputed.

2024-04-19drm/i915/dp: Fix DSC line buffer depth programmingImre Deak1-3/+0
Fix the calculation of the DSC line buffer depth. This is limited both by the source's and sink's maximum line buffer depth, but the former one was not taken into account. On all Intel platform's the source's maximum buffer depth is 13, so the overall limit is simply the minimum of the source/sink's limit, regardless of the DSC version. This leaves the DSI DSC line buffer depth calculation as-is, trusting VBT. On DSC version 1.2 for sinks reporting a maximum line buffer depth of 16 the line buffer depth was incorrectly programmed as 0, leading to a corruption in color gradients / lines on the decompressed screen image.

2024-03-26drm/dp: Clarify that wait_hpd_asserted() is not optional for panelsDouglas Anderson1-1/+12
In response to my patch removing the "wait for HPD" logic at the beginning of the MSM DP transfer() callback [1], we had some debate about what the "This is an optional function" meant in the documentation of the wait_hpd_asserted() callback. Let's clarify. As talked about in the MSM DP patch [1], before wait_hpd_asserted() was introduced there was no great way for panel drivers to wait for HPD in the case that the "built-in" HPD signal was used. Panel drivers could only wait for HPD if a GPIO was used. At the time, we ended up just saying that if we were using the "built-in" HPD signal that DP AUX controllers needed to wait for HPD themselves at the beginning of their transfer() callback. The fact that the wait for HPD at the beginning of transfer() was awkward/problematic was the whole reason wait_hpd_asserted() was added. Let's make it obvious that if a DP AUX controller implements wait_hpd_asserted() that they don't need a loop waiting for HPD at the start of their transfer() function. We'll still allow DP controllers to work the old way but mark it as deprecated.

2024-02-28drm/dp: Don't attempt AUX transfers when eDP panels are not poweredDouglas Anderson1-0/+6
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/dp: Add support for DP tunnelingImre Deak2-0/+308
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().
