2 # DMA engine configuration
5 menu "DMA Engine support"
9 bool "Support for DMA engines"
11 DMA engines offload copy operations from the CPU to dedicated
12 hardware, allowing the copies to happen asynchronously.
17 bool "Network: TCP receive copy offload"
18 depends on DMA_ENGINE && NET
21 This enables the use of DMA engines in the network stack to
22 offload receive copy-to-user operations, freeing CPU cycles.
23 Since this is the main user of the DMA engine, it should be enabled;
29 tristate "Intel I/OAT DMA support"
30 depends on DMA_ENGINE && PCI
33 Enable support for the Intel(R) I/OAT DMA engine.
