As detailed in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=948519 and https://wiki.debian.org/BoottimeEntropyStarvation, lack of boot-time entropy can contribute to multi-minute pauses during system initialization in some hardware configurations. While userspace workarounds, e.g. haveged, are documented, the in-kernel jitter entropy collector eliminates the need for such workarounds.
It cherry-picks cleanly to 4.19.y and 4.14.y. I'm particularly interested in the former.
Thanks for considering this.
Please cc: the developers of that commit, and the maintainer of that code, and we will be glad to consider it if they agree it is viable for those kernels.
Personally, this looks like a "new feature" to me, if you really need this, what is preventing you from moving to a newer kernel version?
thanks,
