sure that you know the name of your UFS host adapter (the card |
|
inside your computer that "speaks" the UFS protocol, also |
|
called UFS Host Controller), because you will be asked for it. |

|
help |
|
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. |
