I can see that h-prod calls are only waking hardware threads from a h-cede call when the caller is on the same core as the thread being awoken (sibling theads). For cross core prods the target thread remains in h-cede until its next decrementer interrupt. That is causing guest OS some significant dispatching delays. The fix is now upstream as commit 8464c8842de2 ("KVM: PPC: Book3S HV: Fix H_PROD to actually wake the target vcpu", 2016-12-06) in v4.11-rc1.
