ivshmem has a performance disadvantage for guest-to-host communication. Since the shared memory is exposed as PCI BARs, the guest has to memcpy into the shared memory. vhost-user can access guest memory directly and avoid the copy inside the guest.
Actually, you can avoid this memory copy using frameworks like DPDK.
Unless someone steps up and maintains ivshmem, I think it should be deprecated and dropped from QEMU.
Then I can maintain ivshmem for QEMU. If this is ok, I will send a patch for MAINTAINERS file. -- David Marchand -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
