LWN.net | All | [$] Using dma-bufs for read and write operations |
May 13, 2026 6:40 AM * |
||
The kernel's dma-buf subsystem provides a way for drivers to share memory buffers, usually in order to support efficient device-to-device I/O. At the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit, Pavel Begunkov, assisted by Kanchan Joshi, led a joint session of the storage and memory-management tracks to explore ways to make the use of dma-bufs more efficient yet, and to make them available for read and write operations initiated by user space. https://lwn.net/Articles/1072317/ --- SBBSecho 3.37-Linux * Origin: Palantir * palantirbbs.ddns.net * Pensacola, FL * (618:250/24) |
