It seems like KVM doesn't implement the H_CLEAR_REF and H_CLEAR_MOD
hypervisor calls, which are absolutely critical for memory
management in the FreeBSD kernel (and are marked "mandatory" in the
PAPR manual). It seems some patches have been contributed already
in
https://lists.ozlabs.org/pipermail/linuxppc-dev/2011-December/095013.html,
so it would be fantastic if these could end up upstream.
Paul, I guess we never included this because there was no user. If
FreeBSD does use it though, I think it makes a lot of sense to
resend it for inclusion.
I agree. I just need to check the locking and synchronization around
the reference and change bit recording, then I'll resend it.
Thanks much! Please let me know if I can help at all with this.
Any news on this? I'm happy to test the patch if you like.
