This is a continuation of a patch series adding 9p server support for Darwin,
originally submitted by Keno Fischer in mid-2018
(https://lists.gnu.org/archive/html/qemu-devel/2018-06/msg04643.html).
It has since been updated and rebased for NixOS by Michael Roitzsch
(https://github.com/NixOS/nixpkgs/pull/122420) with a goal of resubmitting
upstream. I am submitting his patch set as suggested, as developed by him, with
his Signed-off-by headers included in full.
Additionally, I have run the patches through checkpatch.pl and adjusted coding
style accordingly (with the exception of ignoring warnings about avoid
architecture specific defines in hw/9pfs/9p-util-darwin.c, where they seem
unavoidable), and have signed off on those modified commits.

Hi Will,
It is strongly recommended that you Cc maintainers to increase the odds
they notice your patches in the flood of qemu-devel. FYI I only noticed
them because git-send-email Cc'd me thanks to the Reviewed-by: tags and
my address didn't change in the meantime. I'm thus Cc'ing Christian
who is the primary maintainer now (i.e. the person that can merge
your patches and send a PR for upstream inclusion).
FWIW git-publish [1] can Cc the relevant people for free.

This makes sense. For consistency with that assumption, it would also
make sense to clear all preexisting Reviewed-by: tags.

QEMU cares about tracking of who did what and follows a policy inspired
from the linux kernel [2] [3].
Michael's Signed-off-by: should then appear on all patches, with a
mention of the extra changes that he made, e.g.
Signed-off-by: Keno Fischer <keno@juliacomputing.com>
[Michael Roitzsch: - rebased for NixOS
- some other change]
Signed-off-by: Michael Roitzsch <reactorcontrol@icloud.com>
If no changes were made, you still need to add a Signed-off-by: tag.

Good ! If you have an account on gitlab, you can also push a branch there.
It will be submitted to gitlab CI and maybe give you the opportunity to
polish the patches some more before submission.

As explained above, your Signed-off-by: is also needed in all patches,
even if you didn't change them.

Many thanks for all the clarifications — it’s my first time using
git-send-email and first time with mailing-list-based devel workflows. Will
adjust accordingly, work through gitlab, and eventually resend via
git-publish as v2.

So the intended use case is macOS being host.
Has this been tested, and if yes, using which 9p client and which macOS
version?

Correct. It's been tested and functions when applied to QEMU master, with
host running macOS Big Sur 11.6 (personal machine) using client 9p2000.L
(taking a cue from the guest mounting instructions on
https://wiki.qemu.org/Documentation/9psetup).

So it was the Linux kernel's 9p client on guest side with 9p 'local' fs driver
and 9p transport driver was 'virtio-pci'.
I was just wondering if somebody already bothered for macOS being the guest,
because that use case is a bit more challenging, especially with macOS 11 and
higher. But I see that's nothing you were into.

Correct, sorry for the imprecise language. The use case being contemplated
is limited to Linux as the guest side, specifically for cross-platform
tools where the macOS implementation consists of integrating a Linux VM via
QEMU.
NixOS (updater of the original patch,
https://github.com/NixOS/nixpkgs/pull/122420) would be able to use this to
provide macOS support via a VM.
Lima and Podman as containerization alternatives to Docker would like to
performantly mount volumes between macOS users and their respective VMs.
Lima currently accomplishes this via sshfs, but would like to move to 9p
for stability/performance reasons (https://github.com/lima-vm/lima/issues/20).
Podman has yet to fully settle on an implementation at all due to similar
outstanding concerns, but the furthest along proposed implementation choice
has been 9pfs as well (https://github.com/containers/podman/pull/11454),
pending adoption of such functionality in QEMU upstream.

I only had a glimpse on the patches so far. From what I've seen, I don't
expect much of a problem to bring this series through. I will have a closer
look on v2 though. I also have to read the old discussions where I was not
involved yet.
Soft freeze for QEMU 6.2 is close BTW (November 2nd):
