CONFIG_BLK_DEV_UMEM: Micro Memory MM5415 Battery Backed RAM support

General informations

The Linux kernel configuration item CONFIG_BLK_DEV_UMEM has multiple definitions:

Micro Memory MM5415 Battery Backed RAM support found in drivers/block/Kconfig

The configuration item CONFIG_BLK_DEV_UMEM:

• prompt: Micro Memory MM5415 Battery Backed RAM support
• type: tristate
• depends on: CONFIG_PCI
• defined in drivers/block/Kconfig
• found in Linux kernels: 3.7–3.19, 4.0–4.20, 5.0–5.12
• modules built: umem

Help text

Saying Y here will include support for the MM5415 family of battery backed (Non-volatile) RAM cards. http://www.umem.com/

The cards appear as block devices that can be partitioned into as many as 15 partitions.

To compile this driver as a module, choose M here: the module will be called umem.

The umem driver has not yet been allocated a MAJOR number, so one is chosen dynamically.
