We used to synchronize pending MSI-X irq handlers via synchronize_irq(), this may not work for the untrusted device which may keep sending interrupts after reset which may lead unexpected results. Similarly, we should not enable MSI-X interrupt until the device is ready.You mean until the driver is ready.
RIght, I will fix it. Thanks _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
