Add --total option to enable visualization of time spent not within a sub
|
ok, I think I figured out a use case: I could micro-benchmark over a fixed time interval, say for non-regression testing, and then show each flame graph over the same time range to match the interval (with the missing samples due to off-CPU blocking). |

The use case for this option is comparing multiple perf runs directly against one another. Specifying the # of samples to use for the total width means the individual rectangles in each graph can be directly compared to each other rather than being resized differently if one run finished more quickly than another.

This simply makes the "all" line at the bottom of the flame graph wider.
