0. Preface
The previous ten lectures introduced the Go runtime scheduler, and this lecture provides a general overview of the Go runtime scheduler along with some diagrams.
1. State transition diagrams
First is the state transition diagram of the Goroutine:
Most of the transfer paths have also been described in previous lectures and will not be continued here (below).
Next is the state transfer diagram for P:
Finally, there is a state transfer diagram for thread M:
