In this case, existing code -keeps adding more sinks to link. - -This change assumes dc_link_detect will detect the correct new state and -add the new sinks properly. -So at the start of dc_link_detect, we should first detach all existing sinks. - -Signed-off-by: Jordan Lazare <Jordan.Lazare@amd.com> -Acked-by: Jordan Lazare <Jordan.Lazare@amd.com> ---- - drivers/gpu/drm/amd/dal/dc/core/dc_link.c | 7 +++++-- - 1 file changed, 5 insertions(+), 2 deletions(-) - -diff --git a/drivers/gpu/drm/amd/dal/dc/core/dc_link.c b/drivers/gpu/drm/amd/dal/dc/core/dc_link.c -index 5e39a41..5f24ef1 100644 ---- a/drivers/gpu/drm/amd/dal/dc/core/dc_link.c -+++ b/drivers/gpu/drm/amd/dal/dc/core/dc_link.c -@@ -571,6 +571,11 @@ void dc_link_detect(const struct dc_link *dc_link) - return; - } - -+ /* Free existing state before doing detection on SST -+ * TODO: For MST, need to investigate if the same is required. */ -+ if (link->public.type != dc_connection_mst_branch) -+ link_disconnect_all_sinks(link); -+ - if (new_connection_type != dc_connection_none) { - link->public.type = new_connection_type; - -@@ -718,8 +723,6 @@ void dc_link_detect(const struct dc_link *dc_link) - /* From Connected-to-Disconnected. */ - if (link->public.type == dc_connection_mst_branch) - dc_helpers_dp_mst_stop_top_mgr(link->ctx, &link->public); -- else -- link_disconnect_all_sinks(link); - - link->public.type = dc_connection_none; - sink_caps.signal = SIGNAL_TYPE_NONE; --- -2.7.4 - |
