pm-graph: AnalyzeBoot v2.2
- add -cgskip option to reduce callgraph output size - add -cgfilter option to focus on a list of devices - add -result option for exporting batch test results - removed all phoronix hooks, use -result to enable batch testing - changed argument -f to match sleegraph, -f = -callgraph - use -fstat for function status instead of -f - add -verbose option to print out timeline stats and kernel options - include command string and kernel params in timeline output header Signed-off-by: Todd Brandt <todd.e.brandt@linux.intel.com> Signed-off-by: Rafael J.
