KVM: PPC: Book3S HV: Add tunable to control H_IPI redirection 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 control this feature. The default value for this tunable is 1 - that is enable the feature. Signed-off-by: Suresh Warrier <warrier@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
