From d188db8aed74547f98b905254d4f57baf225f1d6 Mon Sep 17 00:00:00 2001 From: Mathew McBride Date: Mon, 21 Aug 2023 06:10:35 +0000 Subject: [PATCH] kernel: add vhost-net module vhost-net is used to accelerate traffic to virtualisation guests that use the virtio-net network card in QEMU. Generally it is invoked by specifying "vhost=on" to a QEMU -netdev device: qemu-system-aarch64 -nographic -M virt -cpu host \ --enable-kvm -bios u-boot.bin -smp 1 -m 2048 \ -drive file=openwrt-armsr-armv8.img,format=raw,index=0,media=disk \ -device "virtio-net,netdev=landev,disable-legacy=off,disable-modern=off" \ -netdev "tap,id=landev,helper=/usr/lib/qemu-bridge-helper --br=br-lan,vhost=on" Signed-off-by: Mathew McBride --- package/kernel/linux/modules/virt.mk | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) diff --git a/package/kernel/linux/modules/virt.mk b/package/kernel/linux/modules/virt.mk index 90226b4806..1d9caa9bc8 100644 --- a/package/kernel/linux/modules/virt.mk +++ b/package/kernel/linux/modules/virt.mk @@ -117,3 +117,27 @@ define KernelPackage/vfio-pci/description endef $(eval $(call KernelPackage,vfio-pci)) + + +define KernelPackage/vhost + SUBMENU:=Virtualization + TITLE:=Host kernel accelerator for virtio (base) + KCONFIG:=CONFIG_VHOST + FILES:=$(LINUX_DIR)/drivers/vhost/vhost.ko \ + $(LINUX_DIR)/drivers/vhost/vhost_iotlb.ko + AUTOLOAD:=$(call AutoProbe,vhost vhost_iotlb) +endef + +$(eval $(call KernelPackage,vhost)) + + +define KernelPackage/vhost-net + SUBMENU:=Virtualization + TITLE:=Host kernel accelerator for virtio-net + DEPENDS:=+kmod-tun +kmod-vhost + KCONFIG:=CONFIG_VHOST_NET + FILES:=$(LINUX_DIR)/drivers/vhost/vhost_net.ko + AUTOLOAD:=$(call AutoProbe,vhost_net) +endef + +$(eval $(call KernelPackage,vhost-net)) -- 2.30.2
