Nicholas Piggin 6cd8b30790 KVM: PPC: Book3S HV Nested: L2 LPCR should inherit L1 LPES setting ... [ Upstream commit 2852ebfa10 ] The L1 should not be able to adjust LPES mode for the L2. Setting LPES if the L0 needs it clear would cause external interrupts to be sent to L2 and missed by the L0. Clearing LPES when it may be set, as typically happens with XIVE enabled could cause a performance issue despite having no native XIVE support in the guest, because it will cause mediated interrupts for the L2 to be taken in HV mode, which then have to be injected.
