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