interconnect: Add interconnect_graph file to debugfs

2019-12-16T07:49:54+00:00

The interconnect graphs can be difficult to understand and the current "interconnect_summary" file doesn't even display links in any way. Add a new "interconnect_graph" file to debugfs in the graphviz "dot" format which describes interconnect providers, nodes and links. The file is human-readable and can be visualized by piping through graphviz. Example: ssh $TARGET cat /sys/kernel/debug/interconnect/interconnect_graph \ | dot -Tsvg > interconnect_graph.svg Signed-off-by: Leonard Crestez Reviewed-by: Greg Kroah-Hartman Reviewed-by: Bjorn Andersson Signed-off-by: Georgi Djakov
