This patch adds support to real-mode KVM to search for a core
running in the host partition and send it an IPI message with
VCPU to be woken. This avoids having to switch to the host
partition to complete an H_IPI hypercall when the VCPU which
is the target of the the H_IPI is not loaded (is not ru
Redirecting the wakeup of a VCPU from the H_IPI hypercall to
a core running in the host is usually a good idea, most workloads
seemed to benefit. However, in one heavily interrupt-driven SMT1
workload, some regression was observed. This patch adds a kvm_hv
module parameter called h_ipi_redirect to

Why did I pick that one? A later patch plans on deleting the

could have renamed that one for less

Hi, Kevin,
Can you tell how to reset/reboot this VM, if it goes to the handle_hwpic1()
on its booting procedure? I mean, usually, SeaBIOS would not go to
handle_hwpic routine. But in my test case, SeaBIOS calls handle_hwpic when
KVM injects a #UD expcetion (not irq) and SeaBIOS will loop to handl
