FSI - the FRU Support Interface - is a simple bus for low-level

access to POWER-based hardware.

config FSI_NEW_DEV_NODE

|
|
---help---
|
|
This option causes char devices created for FSI devices to be
|
|
located under a common /dev/fsi/ directory. Set to N unless your
|
|
userspace has been updated to handle the new location.
|
|
|
|
Additionally, it also causes the char device names to be offset
|
|
by one so that chip 0 will have /dev/scom1 and chip1 /dev/scom2
|
|
to match old userspace expectations.
|
|
|
|
New userspace will use udev rules to generate predictable access
|
|
symlinks in /dev/fsi/by-path when this option is enabled.

This option enables a FSI master driver using GPIO lines.

tristate "FSI hub master"
|
|
---help---
|
|
This option enables a FSI hub master driver. Hub is a type of FSI
|
|
master that is connected to the upstream master via a slave. Hubs
|
|
allow chaining of FSI links to an arbitrary depth. This allows for
|
|
a high target device fanout.

---help---
|
|
This option enables a FSI master using the AST2400 and AST2500 GPIO

|
lines driven by the internal ColdFire coprocessor. This requires

the corresponding machine specific ColdFire firmware to be available.

depends on OF_ADDRESS
|

---help---
|

This option enables an FSI based SBEFIFO device driver. The SBEFIFO is
|
|
a pipe-like FSI device for communicating with the self boot engine
|
|
(SBE) on POWER processors.

---help---
|
|
This option enables an SBEFIFO based On-Chip Controller (OCC) device
|
|
driver. The OCC is a device embedded on a POWER processor that collects
|
|
and aggregates sensor data from the processor and system. The OCC can
|
|
provide the raw sensor data as well as perform thermal and power
|
|
management on the system.
