drm/amdgpu: xgmi_fill_topology_info

2023-12-13T20:09:55+00:00

1. Use the mirrored topology info to fill links for VF. The new solution is required to simplify and optimize host driver logic. Only use the new solution for VFs that support full duplex and extended_peer_link_info otherwise the info would be incomplete. 2. avoid calling extended_link_info on VF as its not supported Signed-off-by: Vignesh Chander Reviewed-by: Zhigang Luo Reviewed-by: Jonathan Kim Signed-off-by: Alex Deucher

drm/amdgpu: expose the connected port num info through sysfs

2023-11-17T14:30:51+00:00

By catting the xgmi_port_num sysfs node, it prints out the info in the format of : -> : for one xgmi link. For example, in case of 4 sockets fully and evenly connected setup, it would be like as below for the first node in the hive. 01:02 -> 02:03 01:03 -> 02:02 01:07 -> 03:04 01:04 -> 03:07 01:06 -> 04:05 01:05 -> 04:06 Based on the fact that there is two xgmi links between each socket pair, "01:02 -> 02:03" means that the current socket in question use the port 2 to connect with port 3 of the second node in the hive and so on. v2: print out the src/dst node id for each xgmi link (lijo) v3: replace the current_node++ with +1 to align with dst node (le) and use the dev_err instead of pr_err (lijo) v4: fix checkpatch warning (alex) Signed-off-by: Shiwu Zhang Acked-by: Lijo Lazar Reviewed-by: Le Ma Signed-off-by: Alex Deucher
