2 # DMA engine configuration
5 menu "DMA Engine support"
9 bool "Support for DMA engines"
11 DMA engines offload bulk memory operations from the CPU to dedicated
12 hardware, allowing the operations 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.
36 tristate "Intel IOP ADMA support"
37 depends on DMA_ENGINE && (ARCH_IOP32X || ARCH_IOP33X || ARCH_IOP13XX)
41 Enable support for the Intel(R) IOP Series RAID engines.
