[osv-dev] [PATCH 5/6] virtio-fs: add basic read using the DAX window

When the DAX window is available from the device, the filesystem prefers to use it instead of the regular FUSE_READ request. If that fails, FUSE_READ is used as a fallback. To use the DAX window, a part of the file is mapped to it with FUSE_SETUPMAPPING, the contents are copied from it to the

[osv-dev] [PATCH 0/6] virtio-fs: initial support for DAX window

This adds initial support for utilizing the DAX window of a virtio-fs device, building on top of the low-level support for shared memory regions in PCI virtio devices. The focus for this patch series is on getting the implementation right and not on optimizing performance (which is the motive

[osv-dev] [PATCH 6/6] virtio-fs: refactor driver / fs

Since in virtio-fs the filesystem is very tightly coupled with the driver, this tries to make clear the dependence of the first on the second, as well as simplify. This includes: - The definition of fuse_request is moved from the fs to the driver, since it is part of the interface it provides.
