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

2025-01-14drm/atomic: clarify the rules around drm_atomic_state->allow_modesetSimona Vetter
msm is automagically upgrading normal commits to full modesets, and that's a big no-no: - for one this results in full on->off->on transitions on all these crtc, at least if you're using the usual helpers. Which seems to be the case, and is breaking uapi - further even if the ctm change itself would not result in flicker, this can hide modesets for other reasons. Which again breaks the uapi v2: I forgot the case of adding unrelated crtc state. Add that case and link to the existing kerneldoc explainers.

2025-01-10drm/ttm: Handle cgroup based eviction in TTMMaarten Lankhorst
cgroup resource allocation has to be handled in TTM, so -EAGAIN from cgroups can be converted into -ENOSPC, and the limitcg can be properly evicted in ttm code. When hitting a resource limit through -EAGAIN, the cgroup for which the limit is hit is also returned. This allows eviction to delete only from cgroups which are a subgroup of the current cgroup. The returned CSS is used to determine if eviction is valuable for a given resource, and allows TTM to only target specific resources to lower memory usage.

When memory stats is generated fresh everytime by going though all the BOs, their active information is quite easy to get. But if the stats are tracked with BO's state this becomes harder since the job scheduling part doesn't really deal with individual buffers.

2024-12-17drm/connector: Add a way to init/add a connector in separate stepsImre Deak
Atm when the connector is added to the drm_mode_config::connector_list, the connector may not be fully initialized yet. This is not a problem for static connectors initialized/added during driver loading, for which the driver ensures that look-ups via the above list are not possible until all the connector and other required state is fully initialized already. It's also not a problem for user space looking up either a static or dynamic (see what this is below) connector, since this will be only possible once the connector is registered. A dynamic - atm only a DP MST - connector can be initialized and added after the load time initialization is done. Such a connector may be looked up by in-kernel users once it's added to the connector list. In particular a hotplug handler could perform a detection on all the connectors on the list and hence find a connector there which isn't yet initialized. For instance the connector's helper hooks may be unset, leading to a NULL dereference while the detect helper calls the connector's drm_connector_helper_funcs::detect() or detect_ctx() handler. To resolve the above issue, add a way for dynamic connectors to separately initialize the DRM core specific parts of the connector without adding it to the connector list - by calling the new drm_connector_dynamic_init() - and to add the connector to the list later once all the initialization is complete and the connector is registered - by calling the new drm_connector_dynamic_register(). Adding the above 2 functions was also motivated to make the distinction of the interface between static and dynamic connectors clearer: Drivers should manually initialize and register only dynamic connectors (with the above 2 functions). A driver should only initialize a static connector (with one of the drm_connector_init*, drmm_connector_init* functions) while the registration of the connector will be done automatically by DRM core. v2: (Jani) - Let initing DDC as well via drm_connector_init_core(). - Rename __drm_connector_init to drm_connector_init_core_and_add(). v3: - Rename drm_connector_init_core() to drm_connector_dynamic_init(). (Sima) - Instead of exporting drm_connector_add(), move adding the connector to the registration step via a new drm_connector_dynamic_register(). (Sima) - Update drm_connector_dynamic_init()'s function documentation and the commit log according to the above changes. - Update the commit log describing the problematic scenario during connector detection.

The connector->eld is accessed by the .get_eld() callback. This access can collide with the drm_edid_to_eld() updating the data at the same time. Add drm_connector.eld_mutex to protect the data from concurrenct access.
