CONFIG_XEN_BLKDEV_BACKEND: Xen block-device backend driver

General informations

The Linux kernel configuration item CONFIG_XEN_BLKDEV_BACKEND has multiple definitions:

Xen block-device backend driver found in drivers/block/Kconfig

The configuration item CONFIG_XEN_BLKDEV_BACKEND:

• prompt: Xen block-device backend driver
• type: tristate
• depends on: CONFIG_XEN_BACKEND
• defined in drivers/block/Kconfig
• found in Linux kernels: 3.1–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.8, 6.9-rc+HEAD
• modules built: xen-blkback

Help text

The block-device backend driver allows the kernel to export its block devices to other guests via a high-performance shared-memory interface.

The corresponding Linux frontend driver is enabled by the XEN_BLKDEV_FRONTEND configuration option.

The backend driver attaches itself to a any block device specified in the XenBus configuration. There are no limits to what the block device as long as it has a major and minor.

If you are compiling a kernel to run in a Xen block backend driver domain (often this is domain 0) you should say Y here. To compile this driver as a module, chose M here: the module will be called xen-blkback.
