2 # DMA engine configuration
6 bool "DMA Offload Engine support"
7 depends on (PCI && X86) || ARCH_IOP32X || ARCH_IOP33X || ARCH_IOP13XX
9 Intel(R) offload engines enable offloading memory copies in the
10 network stack and RAID operations in the MD driver.
17 tristate "Intel I/OAT DMA support"
22 Enable support for the Intel(R) I/OAT DMA engine present
23 in recent Intel Xeon chipsets.
25 Say Y here if you have such a chipset.
30 tristate "Intel IOP ADMA support"
31 depends on ARCH_IOP32X || ARCH_IOP33X || ARCH_IOP13XX
35 Enable support for the Intel(R) IOP Series RAID engines.
44 bool "Network: TCP receive copy offload"
45 depends on DMA_ENGINE && NET
47 This enables the use of DMA engines in the network stack to
48 offload receive copy-to-user operations, freeing CPU cycles.
49 Since this is the main user of the DMA engine, it should be enabled;
