virtio-fs allow sharing a directory between the host and the guest.
It require virtiofsd daemon running before starting Qemu.
The wiki [1] recommand to enable the following kernel options:
CONFIG_VIRTIO
CONFIG_VIRTIO_FS
CONFIG_DAX
CONFIG_FS_DAX
CONFIG_DAX_DRIVER
CONFIG_ZONE_DEVICE
But virtio-fs works fine with only VIRTIO_FS.
Note: ZONE_DEVICE can only be enabled on aarch64 since kernel >= 5.7.
ARCH_ENABLE_MEMORY_HOTREMOVE support is missing for previous kernel [2].

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
