Subject: [PATCH] fastboot: fix issues and improve output of bootgraph.pl
|
|
|
|
David Sanders reported some issues with bootgraph.pl's display
|
|
of his sytems bootup; this commit fixes these by scaling the graph
|
|
not from 0 - end time but from the first initcall to the end time;
|
|
the minimum display size etc also now need to scale with this, as does
|
|
the axis display.
