Performance Hook GC Kind/Flag documentation

[JMTK]

Where can I find more information about the GC Flags and Kind found here: https://nodejs.org/api/perf_hooks.html#performancenodeentrydetail

I started logging GCs using Performance Observer and have been interested in learning more about the differences in the Flags, and also the differences between Major/Minor/Incremental.

I tried googling it to see if they were v8 flags but I didn't find anything.

Thanks!
