Building on top of : the new infrastructure, this series adds support for handling access : faults (i.e. updating the access flag) in parallel. : : This is expected to provide a performance uplift for cores that do not : implement FEAT_HAFDBS, such as those from the fruit company. KVM: arm64: Condition HW AF updates on config option KVM: arm64: Handle access faults behind the read lock KVM: arm64: Don't serialize if the access flag isn't set KVM: arm64: Return EAGAIN for invalid PTE in attr walker KVM: arm64: Ignore EAGAIN for walks outside of a fault KVM: arm64: Use KVM's pte type/helpers in handle_access_fault() Signed-off-by: Oliver Upton --- 52b603628a2c06be38648aa025daa81e4355a7fc
