91888b5b - drm/i915/dp: Add support for DP tunnel BW allocation

Mon, 26 Feb 2024 18:52:46 +0000

drm/i915/dp: Add support for DP tunnel BW allocationAdd support to enable the DP tunnel BW allocation mode. Follow-uppatches will call the required helpers added here to prepare for amodeset on a link with DP tunnels, the last change in the patchsetactually enabling BWA.With BWA enabled, the driver will expose the full mode list a displaysupports, regardless of any BW limitation on a shared (Thunderbolt)link. Such BW limits will be checked against only during a modeset, whenthe driver has the full knowledge of each display's BW requirement.If the link BW changes in a way that a connector's modelist may alsochange, userspace will get a hotplug notification for all the connectorssharing the same link (so it can adjust the mode used for a display).The BW limitation can change at any point, asynchronously to modesetson a given connector, so a modeset can fail even though the atomic checkfor it passed. In such scenarios userspace will get a bad linknotification and in response is supposed to retry the modeset.v2:- Fix old vs. new connector state in intel_dp_tunnel_atomic_check_state(). (Ville)- Fix propagating the error from intel_dp_tunnel_atomic_compute_stream_bw(). (Ville)- Move tunnel==NULL checks from driver to DRM core helpers. (Ville)- Simplify return flow from intel_dp_tunnel_detect(). (Ville)- s/dp_tunnel_state/inherited_dp_tunnels (Ville)- Simplify struct intel_dp_tunnel_inherited_state. (Ville)- Unconstify object pointers (vs. states) where possible. (Ville)- Init crtc_state while declaring it in check_group_state(). (Ville)- Join obj->base.id, obj->name arg lines in debug prints to reduce LOC. (Ville)- Add/rework intel_dp_tunnel_atomic_alloc_bw() to prepare for moving the BW allocation from encoder hooks up to intel_atomic_commit_tail() later in the patchset.- Disable BW alloc mode during system suspend.- Allocate the required BW for all tunnels during system resume.- Add intel_dp_tunnel_atomic_clear_stream_bw() instead of the open-coded sequence in a follow-up patch.- Add function documentation to all exported functions.- Add CONFIG_USB4 dependency to CONFIG_DRM_I915_DP_TUNNEL.v3:- Rebase on intel_dp_get_active_pipes() change in previous patch.Cc: Ville Syrjälä Reviewed-by: Ville Syrjälä Reviewed-by: Uma Shankar Signed-off-by: Imre Deak Link: https://patchwork.freedesktop.org/patch/msgid/20240226185246.1276018-4-imre.deak@intel.com List of files: /linux-6.15/drivers/gpu/drm/i915/Kconfig
