Subject: [PATCH 0/4] fs: Add 9P filesystem support over virtio
Date: Mon, 6 Jul 2026 21:54:42 +0000 [thread overview]
Message-ID: <20260706215446.4068820-1-visitorckw@gmail.com> (raw)
Add 9P network filesystem support to U-Boot.
It allows U-Boot to directly mount host directories in virtualization
environments via virtio.
The functionality has been verified on qemu arm64 by successfully
loading a Linux kernel image and an initramfs image via 9P, and booting
to the Linux shell.
To test with QEMU:
-fsdev local,id=fsdev0,path=/path/to/host/dir,security_model=none \
-device virtio-9p-device,fsdev=fsdev0,mount_tag=rootfs
U-Boot usage:
=> virtio scan
=> ls 9p - /
=> load 9p - $kernel_addr_r /Image
=> load 9p - $ramdisk_addr_r /initramfs.cpio
=> booti $kernel_addr_r $ramdisk_addr_r:$filesize $fdtcontroladdr
