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.
SCSI HOST support for a parallel SCSI host adapters. List of supported controllers: LSI53C1020 LSI53C1020A LSI53C1030 LSI53C1035 ATTO UL4D
SCSI HOST support for a Fiber Channel host adapters. List of supported controllers: LSIFC909 LSIFC919 LSIFC919X LSIFC929 LSIFC929X LSIFC929XL LSIFC949X LSIFC949E Brocade FC 410/420
SCSI HOST support for a SAS host adapters. List of supported controllers: LSISAS1064 LSISAS1068 LSISAS1064E LSISAS1068E LSISAS1078
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.
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.
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.
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
