.Sh DESCRIPTION
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
is part of the
|
|
|
|
|
.Fx
|
|
|
|
|
NAND framework
|
|
|
|
|
.Xr nand 4
|
|
|
|
|
and can be characterized with the following highlights:
|
|
|
|
|
.Bl -bullet
|
|
|
|
|
.It
|
|
|
|
|
plugs into the
|
|
|
|
|
.Xr nand 4
|
|
|
|
|
framework APIs as if it were a hardware controller (hanging on the nexus bus)
|
|
|
|
|
with real NAND chips connected to it
|
|
|
|
|
.It
|
|
|
|
|
physically part of the kernel code (either statically linked into the kernel
|
|
|
|
|
image or built as a module)
|
|
|
|
|
.It
|
|
|
|
|
controlled with a user space program

|
|
From the user perspective, the
|
|
|
|
|
.Nm
|
|
|
|
|
allows for imitating ONFI-compliant NAND Flash devices as if they were
|
|
|
|
|
attached to the system via a virtual controller.
|
|
|
|
|
.Pp
|
|
|
|
|
Some
|
|
|
|
|
.Nm
|
|
|
|
|
features rely on the ability to log contents to a file, which is achieved
|
|
|
|
|
through the
|
|
|
|
|
.Xr alq 9
|
|
|
|
|
facility.
