Refresh the the qemu-arm64 and qemu-riscv virtio related configs, and update its README.txt; New virtio-net driver has better performance Compared with previous virtio-mmio-net: | | master/-c | master/-s | this/-c | this/-s | | :--------------------: | :-------: | :-------: | :-----: | :-----: | | qemu-armv8a:netnsh | 539Mbps | 524Mbps | 906Mbps | 715Mbps | | qemu-armv8a:netnsh_smp | 401Mbps | 437Mbps | 583Mbps | 505Mbps | | rv-virt:netnsh | 487Mbps | 512Mbps | 760Mbps | 634Mbps | | rv-virt:netnsh_smp | 387Mbps | 455Mbps | 447Mbps | 502Mbps | | rv-virt:netnsh64 | 602Mbps | 595Mbps | 881Mbps | 769Mbps | | rv-virt:netnsh64_smp | 414Mbps | 515Mbps | 491Mbps | 525Mbps | | rv-virt:knetnsh64 | 515Mbps | 457Mbps | 606Mbps | 540Mbps | | rv-virt:knetnsh64_smp | 308Mbps | 389Mbps | 415Mbps | 474Mbps | Note: Both CONFIG_IOB_NBUFFERS=64, using iperf command, all in Mbits/sec Tested in QEMU 7.2.2 Signed-off-by: wangbowen6 <wangbowen6@xiaomi.com> Signed-off-by: Zhe Weng <wengzhe@xiaomi.com>
