CONFIG_SCSI_NCR53C8XX_IOMAPPED: use normal IO

General informations

The Linux kernel configuration item CONFIG_SCSI_NCR53C8XX_IOMAPPED has multiple definitions:

use normal IO found in drivers/scsi/Kconfig

The configuration item CONFIG_SCSI_NCR53C8XX_IOMAPPED:

• prompt: use normal IO
• type: bool
• depends on: CONFIG_SCSI_SYM53C8XX && !( CONFIG_SCSI_ZALON || CONFIG_SCSI_NCR_Q720 )
• defined in drivers/scsi/Kconfig
• found in Linux kernels: 2.5.74–2.5.75

Help text

If you say Y here, the driver will use normal IO, as opposed to memory mapped IO. Memory mapped IO has less latency than normal IO and works for most Intel-based hardware. Under Linux/Alpha only normal IO is currently supported by the driver and so, this option has no effect on those systems.

The normal answer therefore is N; try Y only if you encounter SCSI related problems.
