CONFIG_IEEE1394_SBP2_PHYS_DMA: Enable replacement for physical DMA in SBP2

General informations

The Linux kernel configuration item CONFIG_IEEE1394_SBP2_PHYS_DMA has multiple definitions:

Enable replacement for physical DMA in SBP2 found in drivers/ieee1394/Kconfig

The configuration item CONFIG_IEEE1394_SBP2_PHYS_DMA:

• prompt: Enable replacement for physical DMA in SBP2
• type: bool
• depends on: CONFIG_IEEE1394_SBP2 && CONFIG_VIRT_TO_BUS && CONFIG_EXPERIMENTAL
• defined in drivers/ieee1394/Kconfig
• found in Linux kernels: 2.6.18–2.6.36

Help text

This builds sbp2 for use with non-OHCI host adapters which do not support physical DMA or for when ohci1394 is run with phys_dma=0. Physical DMA is data movement without assistance of the drivers' interrupt handlers. This option includes the interrupt handlers that are required in absence of this hardware feature.

This option is buggy and currently broken on some architectures. If unsure, say N.
