CONFIG_MMC_ATMELMCI_DMA: Atmel MCI DMA support

General informations

The Linux kernel configuration item CONFIG_MMC_ATMELMCI_DMA has multiple definitions:

Atmel MCI DMA support found in drivers/mmc/host/Kconfig

The configuration item CONFIG_MMC_ATMELMCI_DMA:

• prompt: Atmel MCI DMA support
• type: bool
• depends on: CONFIG_MMC_ATMELMCI && ( CONFIG_AVR32 || CONFIG_ARCH_AT91SAM9G45 ) && CONFIG_DMA_ENGINE
• defined in drivers/mmc/host/Kconfig
• found in Linux kernels: 3.1–3.9

Help text

Say Y here to have the Atmel MCI driver use a DMA engine to do data transfers and thus increase the throughput and reduce the CPU utilization.

If unsure, say N.

Atmel MCI DMA support (EXPERIMENTAL) found in drivers/mmc/host/Kconfig

The configuration item CONFIG_MMC_ATMELMCI_DMA:

• prompt: Atmel MCI DMA support (EXPERIMENTAL)
• type: bool
• depends on: CONFIG_MMC_ATMELMCI && ( CONFIG_AVR32 || CONFIG_ARCH_AT91SAM9G45 ) && CONFIG_DMA_ENGINE && CONFIG_EXPERIMENTAL
• defined in drivers/mmc/host/Kconfig
• found in Linux kernels: 2.6.28–2.6.39, 3.0

Help text

Say Y here to have the Atmel MCI driver use a DMA engine to do data transfers and thus increase the throughput and reduce the CPU utilization. Note that this is highly experimental and may cause the driver to lock up.

If unsure, say N.
