- DAXFS is a new read-only open-source file-system for Linux.
- It uses the Linux kernel's direct access (DAX) infrastructure for efficiency.
- Designed for zero-copy reads, bypassing traditional block I/O stack, buffer heads, and page cache.
- Key features include zero-copy efficiency, true physical sharing, hardware integration (GPUs, CXL), and simplicity.
- Primary use cases: multikernel environments, CXL memory pooling, container rootfs sharing, and accelerator data handling.
- Developed by Multikernel.io to enhance multi-kernel architecture and CXL support.
- Announced on Linux Kernel Mailing List; code available on GitHub pending upstream interest.
