| # DMA engine configuration |
| bool "DMA Offload Engine support" |
| depends on (PCI && X86) || ARCH_IOP32X || ARCH_IOP33X || ARCH_IOP13XX |
| Intel(R) offload engines enable offloading memory copies in the |
| network stack and RAID operations in the MD driver. |
| tristate "Intel I/OAT DMA support" |
| Enable support for the Intel(R) I/OAT DMA engine present |
| in recent Intel Xeon chipsets. |
| Say Y here if you have such a chipset. |
| tristate "Intel IOP ADMA support" |
| depends on ARCH_IOP32X || ARCH_IOP33X || ARCH_IOP13XX |
| Enable support for the Intel(R) IOP Series RAID engines. |
| bool "Network: TCP receive copy offload" |
| depends on DMA_ENGINE && NET |
| 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; |
