2024-02-27drm/i915/dp: Add intel_dp_max_link_data_rate()Imre Deak
Add intel_dp_max_link_data_rate() to get the link BW vs. the sink DPRX BW used by a follow-up patch enabling the DP tunnel BW allocation mode. The link BW can be below the DPRX BW due to a BW limitation on a link shared by multiple sinks.

2024-02-27drm/i915/dp: Add support to notify MST connectors to retry modesetsImre Deak
On shared (Thunderbolt) links with DP tunnels, the modeset may need to be retried on all connectors on the link due to a link BW limitation arising only after the atomic check phase. To support this add a helper function queuing a work to retry the modeset on a given port's connector and at the same time any MST connector with streams through the same port. A follow-up change enabling the DP tunnel Bandwidth Allocation Mode will take this into use. v2: - Send the uevent only to enabled MST connectors.

2024-02-27drm/i915: Fix display bpp limit computation during system resumeImre Deak
The system resume display mode restoration should happen with an output configuration matching that of the suspend time saved mode. Since the restored mode configuration is subject to the bpp fallback logic, starting out with an unlimited bpp and reducing the bpp as required by any (MST) link BW limit, the resulting bpp will match the one during suspend only if the BW limit checks during suspend and resume are applied in an identical way. The latter is not guaranteed at the moment, since the pre-suspend MST topology may not be in place during resume (for instance if the MST sink was disconnected while being suspended), which makes the MST link BW check accept the unlimited bpp mode configuration unconditionally without ensuring that the required BW fits into the available MST link BW. To fix the above, initialize the bpp fallback logic with the max link bpp / force-FEC limits left behind by the suspend time mode save.

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. (Ville) - Simplify API removing drm_dp_tunnel_get/put_untracked(). (Ville) - Reuse str_yes_no() instead of a local yes_no_chr().

2024-02-20drm/i915/tv: Fix TV modeMaxime Ripard
Commit 1fd4a5a36f9f ("drm/connector: Rename legacy TV property") failed to update all the users of the struct drm_tv_connector_state mode field, which resulted in a build failure in i915. However, a subsequent commit in the same series reintroduced a mode field in that structure, with a different semantic but the same type, with the assumption that all previous users were updated. Since that didn't happen, the i915 driver now compiles, but mixes accesses to the legacy_mode field and the newer mode field, but with the previous semantics. This obviously doesn't work very well, so we need to update the accesses that weren't in the legacy renaming commit.
