on ARM, a devid field is populated in kvm_msi struct in case the flag is set to KVM_MSI_VALID_DEVID. Let's propagate both flags and devid field in kvm_kernel_irq_routing_entry. Signed-off-by: Eric Auger <eric.auger@linaro.org> --- v2 -> v3: - do not set the type to KVM_IRQ_ROUTING_EXTENDED_MSI anymore as suggested by Andre - correct msi->flags check - propagate the flags --- virt/kvm/irqchip.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) -- 1.9.1
