AMD Posts Newest Linux Patches To Accelerate Page Migration For More Performance
AMD has submitted updated Linux kernel patches to improve page migration performance by enabling batched folio copying and hardware offloading via the DMA interface. The patches, now maintained by AMD engineers after originating from a NVIDIA developer, aim to replace the current single-threaded, folio-by-folio migration method. Testing on an EPYC Zen 3 system showed promising performance gains, with the latest version re-based to Linux 7.1-rc1 and including code improvements.

AMD Posts Newest Linux Patches To Accelerate Page Migration For Better Performance Written by Michael Larabel in Linux Kernel on 30 April 2026 at 06:12 AM EDT. Add A Comment Posted to the Linux kernel mailing list this week was the newest revision of a patch series originally started in early 2025 by a NVIDIA engineer for accelerating page migration. Now being worked on by AMD engineers, this accelerated page migration via batch copies and hardware offloading continues to show promising results. AMD engineer Shivank Garg posted the latest request for comments (RFC) patches on speeding up page migration in the Linux kernel by batching folio-copy operations and providing accelerated hardware offloading using the DMA offload interface.
