danobi/vmtest is going to migrate from using 9p to using virtio_fs to mount the local rootfs: https://github.com/danobi/vmtest/pull/88 BPF CI uses danobi/vmtest to run bpf selftests and will need to support VIRTIO_FS. This change enables new kconfigs to be able to support the upcoming danobi/vmtest. Tested by building a new kernel with those config and confirming it would successfully run with 9p (currently what is used by vmtest), and with virtio_fs (using a local build of vmtest). $ vmtest -k arch/x86/boot/bzImage "findmnt /" => bzImage ===> Booting ===> Setting up VM ===> Running command TARGET SOURCE FSTYPE OPTIONS / /dev/root 9p rw,relatime,cache=5,access=client,msize=512000,trans=virtio $ /home/chantra/local/danobi-vmtest/target/debug/vmtest -k arch/x86/boot/bzImage "findmnt /" => bzImage ===> Initializing host environment ===> Booting ===> Setting up VM ===> Running command TARGET SOURCE FSTYPE OPTIONS / rootfs virtiofs rw,relatime Signed-off-by: Manu Bretelle <chantr4@xxxxxxxxx> --- tools/testing/selftests/bpf/config.vm | 3 +++ 1 file changed, 3 insertions(+) diff --git a/tools/testing/selftests/bpf/config.vm b/tools/testing/selftests/bpf/config.vm index a9746ca78777..b96b1fad2a04 100644 --- a/tools/testing/selftests/bpf/config.vm +++ b/tools/testing/selftests/bpf/config.vm @@ -10,3 +10,6 @@ CONFIG_VIRTIO_CONSOLE=y CONFIG_VIRTIO_NET=y CONFIG_VIRTIO_PCI=y CONFIG_VIRTIO_VSOCKETS_COMMON=y +CONFIG_FUSE_FS=y +CONFIG_VIRTIO_FS=y +CONFIG_FUSE_PASSTHROUGH=y -- 2.43.5
