[PATCH OLK-6.6] mm: migrate: add dma copy offloading for hugetlb
by Zeng Heng 15 Dec '25

15 Dec '25

From: Tong Tiangen <tongtiangen(a)huawei.com> hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IDBGTZ CVE: NA ------------------------------- Large memory migration imposes significant overhead on the CPU. This patch introduces enhancements to the page migration by offloading the copy to UDMA hardware which based on the DMA engine framework, and a new migration mode has been introduced, If DMA migration fails, it will fall back to CPU migration. DMA migration supports both asynchronous and synchronous modes for subsequent debugging purposes.
