CONFIG_RAW_DRIVER: RAW driver (/dev/raw/rawN)
General informations
The Linux kernel configuration item CONFIG_RAW_DRIVER has multiple definitions:
RAW driver (/dev/raw/rawN) (OBSOLETE) found in arch/um/Kconfig.char
The configuration item CONFIG_RAW_DRIVER:
- prompt: RAW driver (/dev/raw/rawN) (OBSOLETE)
- type: tristate
- depends on:
(none) - defined in arch/um/Kconfig.char
- found in Linux kernels: 2.6.21–2.6.25
- modules built:
raw,raw
Help text
The raw driver permits block devices to be bound to /dev/raw/rawN. Once bound, I/O against /dev/raw/rawN uses efficient zero-copy I/O. See the raw(8) manpage for more details.
The raw driver is deprecated and will be removed soon. Applications should simply open the device (eg /dev/hda1) with the O_DIRECT flag.

The raw driver permits block devices to be bound to /dev/raw/rawN. Once bound, I/O against /dev/raw/rawN uses efficient zero-copy I/O. See the raw(8) manpage for more details.
Applications should preferably open the device (eg /dev/hda1) with the O_DIRECT flag.
