Does KVM hypervisor work? Previous Qualcomm CPUs have locked hypervisor mode behind Qualcomm proprietary blobs, and only allowed HyperV to use it - this was definitely the case for WOS laptops.

I worked at Linaro, who was contracting for Qualcomm. Qualcomm were pushing for some protected hypervisor called Gunyah (which had its own Linux interface and needed a new qemu port) that apparently no one liked. I tried to port it to KVM [1], but upstream folks (mostly Google) outright rejected the port. Otherwise KVM would have been available on QCOM boards. You can still try it. I have a Linux kernel and a Qemu port on my github [2,3]

MS Windows had an exclusive period for X1, but Google will support Android and ChromeOS on Qualcomm X2-based devices in 2026, which would require the pKVM/KVM hypervisor used by Android, https://news.ycombinator.com/item?id=45368167

The original Oryon systems allowed you to boot directly into EL2 and skip Gunyah via BIOS settings. I assume this will be the same.
