From: Leo Li <sunpeng.li@xxxxxxx> Hi all, This is a follup to this change made by Ville to add MST aux nodes: https://github.com/vsyrjala/linux/commit/cac63f799ee2f5fbbe4f0a375383f13e03d640a5 Patch 2/2 describes what I added on top. Sending as an RFC since there are some items I'm not certain on: 1) Only expose aux devices for physical ports. FWICT, only DPTX and DPRX can handle AUX transactions, leaving logical ports out. 2) Naming of exposed AUX devices. I'm not sure if the scheme implemented here is the best approach. Let me know your thoughts, Leo Leo Li (1): drm/dp_mst: Use non-cyclic idr, add suffix option for aux device Ville Syrjälä (1): drm/dp_mst: Register aux-dev nodes for MST ports drivers/gpu/drm/drm_crtc_helper_internal.h | 5 +- drivers/gpu/drm/drm_dp_aux_dev.c | 21 ++++-- drivers/gpu/drm/drm_dp_helper.c | 2 +- drivers/gpu/drm/drm_dp_mst_topology.c | 109 +++++++++++++++++++++++++---- include/drm/drm_dp_helper.h | 4 ++ include/drm/drm_dp_mst_helper.h | 6 ++ 6 files changed, 125 insertions(+), 22 deletions(-) -- 2.7.4 _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx
