This week, Demi and I continued the review of the patches adding PipeWire to guests, now on their seventh revision[1], with some preparatory patches having already been applied[2][3]. She also opened a couple of Cloud Hypervisor PRs[4][5], one of which adds support for a generic vhost-user device. This would be a very exciting feature for Cloud Hypervisor to gain, because it would mean using new kinds of vhost-user device with Cloud Hypervisor wouldn't require any Cloud Hypervisor modifications. I believe (but we haven't confirmed yet) that this should allow using a vhost-user-sound device with Cloud Hypervisor straight away, and eventually allow us to drop our patches for GPU support altogether, although that also requires some extra vhost-user messages to be standardised (an effort which is still ongoing[6]).

As for me, aside from reviewing and applying some of Demi's fixes, I updated Spectrum's pinned Nixpkgs[7] and released a new version of the Cloud Hypervisor patches[8], and did the usual round of server updates. Sometimes, updating the pinned Nixpkgs is easy, otherwise, due to a change that looked entirely inconsequential upstream, it can take a lot of work, and this has been one of the latter variety, so I'm glad it's finally done. Since then, and having just returned home from a couple of months of travelling, I've been feeling very tired. A few weeks ago[8], I mentioned that I'd been thinking I might have to calm things down a bit for myself to make sure I'm on the right side of burnout, and I think now is probably the time for that, so I'd expect there won't be much direct progress from me for the next week or two, although I should still be keeping up with emails — feeling like I'd come back to a mountain of them would be much worse than just dealing with them roughly as they come in — and doing what I can to make sure nobody else is blocked.
