menu "DMA Engine support"
depends on !S390
config DMA_ENGINE
bool "Support for DMA engines"
---help---
DMA engines offload bulk memory operations from the CPU to dedicated
hardware, allowing the operations to happen asynchronously.
comment "DMA Clients"
config NET_DMA
bool "Network: TCP receive copy offload"
depends on DMA_ENGINE && NET
default y
---help---
This enables the use of DMA engines in the network stack to
offload receive copy-to-user operations, freeing CPU cycles.
Since this is the main user of the DMA engine, it should be enabled;
say Y here.
comment "DMA Devices"
config INTEL_IOATDMA
tristate "Intel I/OAT DMA support"
depends on DMA_ENGINE && PCI
default m
---help---
Enable support for the Intel(R) I/OAT DMA engine.
