[-- Attachment #1 --] hi! * yes this is awesome! * send over what you have when you're comfortable and we can figure out how to get what bits landed * i prefer reviews in https://reviews.freebsd.org/ , if you have your work in a github or similar branch then please share what you have and we can figure it out from there * yes i really should sit down and get ppc64le/ppc64 packages built for 16 and 15 * yes please send through a list of technical challenges, that'd be great! also: * for us who have hardware (eg i have an S822 which I need to setup to run LPARs) it would be nice to cover what you did and how to get it going. I've had issues even trying to get the bootloader to be loaded and jumped into in previous testing so any/all info you have to get this going would be super great.
