Universal Flash Storage (UFS) is SCSI transport specification for
|
||
|
|
accessing flash storage on digital cameras, mobile phones and
|
||
|
|
consumer electronic devices.
|
||
|
|
A UFS controller communicates with a UFS device by exchanging
|
||
|
|
UFS Protocol Information Units (UPIUs).
|
||
|
|
UPIUs can not only be used as a transport layer for the SCSI protocol
|
||
|
|
but are also used by the UFS native command set.
|
||
|
|
This transport driver supports exchanging UFS protocol information units
|
||
|
|
with a UFS device. See also the ufshcd driver, which is a SCSI driver
|
||
|
|
that supports UFS devices.
|
||
|
|
|
||
|
|
Select this if you need a bsg device node for your UFS controller.
|
||
|
|
If unsure, say N.

help
|

|
|
Enable Crypto Engine Support in UFS.
|
||
|
|
Enabling this makes it possible for the kernel to use the crypto
|
||
|
|
capabilities of the UFS device (if present) to perform crypto
|
||
|
|
operations on data being transferred to/from the device.

help
|

|
|
The UFS HPB feature improves random read performance. It caches
|
||
|
|
L2P (logical to physical) map of UFS to host DRAM. The driver uses HPB
|
||
|
|
read command by piggybacking physical page number for bypassing FTL (flash
|
||
|
|
translation layer)'s L2P address translation.

Enable fault injection support in the UFS driver. This makes it easier
|
||
|
|
to test the UFS error handler and abort handler.

This provides support for UFS hardware monitoring. If enabled,
|

|

a hardware monitoring device will be created for the UFS device.
