From: Brian Song <hibrians...@gmail.com> Hello,
This is a GSoC project. You could check out more here: https://wiki.qemu.org/Google_Summer_of_Code_2025#FUSE-over-io_uring_exports This series: - Merges the request processing functions for both traditional FUSE and FUSE-over-io_uring modes - Implements multi-threading (Multi-IOThread) - Improves FUSE-over-io_uring termination handling Due to kernel limitations, when the FUSE-over-io_uring option is enabled, you must create and assign nr_cpu IOThreads. For example: qemu-storage-daemon \ --object iothread,id=iothread1 \ --object iothread,id=iothread2 \ --blockdev node-name=prot-node,driver=file,filename=img.qcow2 \ --blockdev node-name=fmt-node,driver=qcow2,file=prot-node \ --export type=fuse,id=exp0,node-name=fmt-node,mountpoint=mount-point, \ writable=on,iothread.0=iothread1,iothread.1=iothread2 More detail on the v1 cover letter: https://lists.nongnu.org/archive/html/qemu-block/2025-07/msg00280.html Brian Song (3): fuse: add FUSE-over-io_uring enable opt and init fuse: Handle FUSE-uring requests fuse: Safe termination for FUSE-uring block/export/fuse.c | 632 ++++++++++++++++++++------- docs/tools/qemu-storage-daemon.rst | 11 +- qapi/block-export.json | 5 +- storage-daemon/qemu-storage-daemon.c | 1 + util/fdmon-io_uring.c | 5 +- 5 files changed, 486 insertions(+), 168 deletions(-) -- 2.45.2
