2025-01-24drm/dp_mst: Fix drm RAD printWayne Lin
[Why] The RAD of sideband message printed today is incorrect. For RAD stored within MST branch - If MST branch LCT is 1, it's RAD array is untouched and remained as 0. - If MST branch LCT is larger than 1, use nibble to store the up facing port number in cascaded sequence as illustrated below: u8 RAD[0] = (LCT_2_UFP << 4) | LCT_3_UFP RAD[1] = (LCT_4_UFP << 4) | LCT_5_UFP ... In drm_dp_mst_rad_to_str(), it wrongly to use BIT_MASK(4) to fetch the port number of one nibble. [How] Adjust the code by: - RAD array items are valuable only for LCT >= 1. - Use 0xF as the mask to replace BIT_MASK(4) V2: - Document how RAD is constructed (Imre) V3: - Adjust the comment for rad[] so kdoc formats it properly (Lyude) Fixes: 2f015ec6eab6 ("drm/dp_mst: Add sideband down request tracing + selftests") Cc: Imre Deak <imre.deak@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Harry Wentland <hwentlan@amd.com> Cc: Lyude Paul <lyude@redhat.com> Reviewed-by: Lyude Paul <lyude@redhat.com> Signed-off-by: Wayne Lin <Wayne.Lin@amd.com> Signed-off-by: Lyude Paul <lyude@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250113091100.3314533-2-Wayne.Lin@amd.com

2025-01-07drm/mst: remove mgr parameter and debug logging from drm_dp_get_vc_payload_bw()Jani Nikula
The struct drm_dp_mst_topology_mgr *mgr parameter is only used for debug logging in case the passed in link rate or lane count are zero. There's no further error checking as such, and the function returns 0. There should be no case where the parameters are zero. The returned value is generally used as a divisor, and if we were hitting this, we'd be seeing division by zero. Just remove the debug logging altogether, along with the mgr parameter, so that the function can be used in non-MST contexts without the topology manager. v2: Also remove drm_dp_mst_helper_tests_init as unnecessary (Imre) Cc: Imre Deak <imre.deak@intel.com> Cc: Lyude Paul <lyude@redhat.com> Reviewed-by: Imre Deak <imre.deak@intel.com> Acked-by: Maxime Ripard <mripard@kernel.org> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/72d77e7a7fe69c784e9df048b7e6f250fd7599e4.1735912293.git.jani.nikula@intel.com

2024-12-05drm/dp_mst: Fix resetting msg rx state after topology removalImre Deak
If the MST topology is removed during the reception of an MST down reply or MST up request sideband message, the drm_dp_mst_topology_mgr::up_req_recv/down_rep_recv states could be reset from one thread via drm_dp_mst_topology_mgr_set_mst(false), racing with the reading/parsing of the message from another thread via drm_dp_mst_handle_down_rep() or drm_dp_mst_handle_up_req(). The race is possible since the reader/parser doesn't hold any lock while accessing the reception state. This in turn can lead to a memory corruption in the reader/parser as described by commit bd2fccac61b4 ("drm/dp_mst: Fix MST sideband message body length check"). Fix the above by resetting the message reception state if needed before reading/parsing a message. Another solution would be to hold the drm_dp_mst_topology_mgr::lock for the whole duration of the message reception/parsing in drm_dp_mst_handle_down_rep() and drm_dp_mst_handle_up_req(), however this would require a bigger change. Since the fix is also needed for stable, opting for the simpler solution in this patch.

2024-06-12drm/connector: hdmi: allow disabling Audio InfoframeDmitry Baryshkov
Add drm_atomic_helper_connector_hdmi_disable_audio_infoframe(), an API to allow the driver disable sending the Audio Infoframe. This is to be used by the drivers if setup of the infoframes is not tightly coupled with the audio functionality and just disabling the audio playback doesn't stop the HDMI hardware from sending the Infoframe.

2024-05-28drm/connector: hdmi: Add Infoframes generationMaxime Ripard
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.
