pmf(9) and Xen domU suspending?
I am working on suspend/resume functionality for port-xen under the
supervision of Manuel Bouyer (bouyer@) and Stoned Elipot (seb@).
Currently, I am mostly trying to get familiar with NetBSD internals, and
While studying the code regarding devices relating to port-xen (xenbus,
xennet, hypervisor...), I was thinking at how I should implement the
suspend/resume mechanisms for theses devices and buses (inspired by ACPI
states). Manuel suggested me to have a look at pmf(9), but the
documentation tends to be scarce (compared to autoconf machinery on
"NetBSD internals"). And since pmf(9) is still a WIP, I am a bit lost
The man page points me to the MI implementation of it in the kernel.
However, I would like to know if there lies somewhere some "canonical"
example (or how-to) I could read just to get a better understanding of it.
Thanking you in advance for your time and patience,
