[PATCH v4 00/15] virtio-mem: paravirtualized memory
This series is based on v5.7-rc4. The patches are located at:
https://github.com/davidhildenbrand/linux.git virtio-mem-v4
This is basically a resend of v3 [1], now based on v5.7-rc4 and restested.
One patch was reshuffled and two ACKs I missed to add were added. The
rebase did not require any modifications to patches.
Details about virtio-mem can be found in the cover letter of v2 [2]. A

[PATCH v2 00/10] virtio-mem: paravirtualized memory
This series is based on latest linux-next. The patches are located at:
https://github.com/davidhildenbrand/linux.git virtio-mem-v2
I now have acks for all !virtio-mem changes. I'll be happy to get review
feedback, testing reports, etc. for the virtio-mem changes. If there are
no further comments, I guess this is good to go as a v1 soon.
The basic idea of virtio-mem is to provide a

This series is based on latest linux-next. The patches are located at:
https://github.com/davidhildenbrand/linux.git virtio-mem-rfc-v4
The basic idea of virtio-mem is to provide a flexible,
cross-architecture memory hot(un)plug solution that avoids many limitations
imposed by existing technologies, architectures, and interfaces. More
details can be found below and in linked material.

[PATCH RFC v3 0/9] virtio-mem: paravirtualized memory
Long time no RFC! I finally had time to get the next version of the Linux
driver side of virtio-mem into shape, incorporating ideas and feedback from
previous discussions.
This RFC is based on the series currently on the mm list:
- [PATCH 0/3] Remove __online_page_set_limits()
- [PATCH v1 0/3] mm/memory_hotplug: Export generic_online_page()
- [PATCH v4 0/8] mm/memory_hotplug: Shrink zones before

[PATCH v2 00/24] virtio: config space endian-ness cleanup
Config space endian-ness is currently a mess: fields are
not tagged with the correct endian-ness so it's easy
to make mistakes like instanciating config space in
native endian-ness.
The following patches adding sparse tagging are currently in my tree.
Lightly tested.
As a follow-up, I plan to add new APIs that handle modern config space
in a more efficient way (bypassing the version check).
