menuconfig FUSION
bool "Fusion MPT device support"
depends on PCI
---help---
Say Y here to get to see options for Fusion Message
Passing Technology (MPT) drivers.
This option alone does not add any kernel code.
If you say N, all options in this submenu will be skipped and disabled.
if FUSION
config FUSION_SPI

---help---
SCSI HOST support for a parallel SCSI host adapters.

---help---
SCSI HOST support for a SAS host adapters.
List of supported controllers:

config FUSION_MAX_SGE
int "Maximum number of scatter gather entries (16 - 128)"
default "128"
range 16 128
help
This option allows you to specify the maximum number of scatter-
gather entries per I/O. The driver default is 128, which matches
SCSI_MAX_PHYS_SEGMENTS. However, it may decreased down to 16.
Decreasing this parameter will reduce memory requirements
on a per controller instance.
config FUSION_CTL
tristate "Fusion MPT misc device (ioctl) driver"
depends on FUSION_SPI || FUSION_FC || FUSION_SAS
---help---
The Fusion MPT misc device driver provides specialized control
of MPT adapters via system ioctl calls. Use of ioctl calls to
the MPT driver requires that you create and use a misc device
node ala:
mknod /dev/mptctl c 10 240
One use of this ioctl interface is to perform an upgrade (reflash)
of the MPT adapter firmware. Refer to readme file(s) distributed
with the Fusion MPT linux driver for additional details.
If enabled by saying M to this, a driver named: mptctl
will be compiled.
If unsure whether you really want or need this, say N.
config FUSION_LAN
tristate "Fusion MPT LAN driver"
depends on FUSION_FC && NET_FC
---help---
This module supports LAN IP traffic over Fibre Channel port(s)
on Fusion MPT compatible hardware (LSIFC9xx chips).
The physical interface used is defined in RFC 2625.
Please refer to that document for details.
Installing this driver requires the knowledge to configure and
activate a new network interface, "fc0", using standard Linux tools.
If enabled by saying M to this, a driver named: mptlan
will be compiled.
If unsure whether you really want or need this, say N.
config FUSION_LOGGING
bool "Fusion MPT logging facility"
---help---
This turns on a logging facility that can be used to debug a number
of Fusion MPT related problems.
The debug level can be programmed on the fly via SysFS (hex values)
echo [level] > /sys/class/scsi_host/host#/debug_level
There are various debug levels that can be found in the source:
file:drivers/message/fusion/mptdebug.h
