I have just = joined the list and wanted to briefly introduce some work we have been doin= g at LibrePower.

Over the past few months, we have been working on running Fre= eBSD as a native PowerVM LPAR on IBM POWER9/10/11. We now have an early PoC= with virtual networking and NPIV-backed storage working, currently tested = on IBM Power Virtual Server.

This is still an early and limited system. We hav= e also started building a small powerpc64le package repository to make the = system more usable.

Some parts of the implementation, including the NPIV work,= have been AI-assisted. We understand the review concerns this may raise, s= o our intention is to submit small, documented patches that can be independ= ently reviewed and tested.

Before proceeding, we would appreciate your guidanc= e:

  • Is PowerVM LPAR support of interest to the project?

  • = Where should we publish the current work and start submitting patches?

  • Would a short technical summary of the blockers, changes and tes= t results be a useful first step?

Definitely. We've gotten a few bug reports for FreeBSD on PowerVM, so we definitely have some interest by others.

    hi!

    * yes this is awesome!
    * send over what you have when you're comfortable and we can f= igure out how to get what bits landed
    * i prefer reviews in https://reviews.freebsd.org/ , if y= ou 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 si= t down and get ppc64le/ppc64 packages built for 16 and 15
    * yes p= lease send through a list of technical challenges, that'd be great!

    also:

    * for us who have hard= ware (eg i have an S822 which I need to setup=C2=A0to run LPARs) it would b= e nice to cover what you did and how to get it going.

    Hello everyone,

    First, thank you = to everyone who has kept FreeBSD on PowerPC alive over the years.

    =

    I have just joined the list and wanted to briefly introduce some work we= have been doing at LibrePower.

    <= div style=3D"font-family:"Helvetica Neue",Helvetica,Arial,sans-se= rif;font-size:14px">

    Over the past few months, we ha= ve been working on running FreeBSD as a native PowerVM LPAR on IBM POWER9/1= 0/11. We now have an early PoC with virtual networking and NPIV-backed stor= age working, currently tested on IBM Power Virtual Server.

    <= /div>

    This= is still an early and limited system. We have also started building a smal= l powerpc64le package repository to make the system more usable.

    <= /div>
    <= p>Some parts of the implementation, including the NPIV work, have been AI-a= ssisted. We understand the review concerns this may raise, so our intention= is to submit small, documented patches that can be independently reviewed = and tested.

    =

    Before proceeding, we would appreciate your guidanc= e:

    • Is PowerVM LPAR support of interest to the project?<= /p>

    • Where should we publish the current work and start submittin= g patches?

    • Would a short technical summary of the blockers, = changes and test results be a useful first step?

    <= /div>

    We w= ould be glad to contribute the work upstream and follow the project=E2=80= =99s preferred review process.
