This week, I worked on a patch series[1] that fixes using a USB serial console on the host. This should be helpful for debugging the modesetting issue Yureka was seeing last week[2]. I also wrote a regression test for the issue, which ended up being the bulk of the work because this is only the second automated test we have that runs a full Spectrum system, so I had to factor some shared helpers for doing those out of the existing ad-hoc single test. Aside from that, I attended DevConf.CZ. The more management-focused talks were particularly helpful, as I'm having to pick bits of that up on the fly as Spectrum grows to have more people working on it.

Yureka is working on improving networking in Spectrum. Currently, networking runs through the host kernel, but the idea is to get it out of there and into userspace, and in future ideally its own VM (perhaps even a microkernel). This week, she started working on getting packets out of the physical network interface using XDP. Demi worked on cleaning up unsound Rust APIs in Cloud Hypervisor, and investigated what a kernel implementation of her proposed virtio-iommu interrupt remapping specification[4] would look like. It turns out to be quite complicated[5], so now we're considering alternative approaches to solving the problem.
