Works for me. Keeping your patch "OvmfPkg: use relaxed AP SMM synchronization mode" in the build (and not broadcasting SMIs in either component) certainly results in a functional binary. The perf penalty could be fine-tuned by decimating the timeout. (I don't recall if I *planned* to divide the current timeout by ten, or actually *tested* it. In any case, I recall thinking that 1/10th of the otherwise seen lag would be pretty tolerable.) So, this works for me definitely.
