4 bool "Fusion MPT device support"
7 Say Y here to get to see options for Fusion Message
8 Passing Technology (MPT) drivers.
9 This option alone does not add any kernel code.
11 If you say N, all options in this submenu will be skipped and disabled.
16 tristate "Fusion MPT ScsiHost drivers for SPI"
17 depends on PCI && SCSI
20 SCSI HOST support for a parallel SCSI host adapters.
22 List of supported controllers:
31 tristate "Fusion MPT ScsiHost drivers for FC"
32 depends on PCI && SCSI
33 depends on SCSI_FC_ATTRS
35 SCSI HOST support for a Fiber Channel host adapters.
37 List of supported controllers:
50 tristate "Fusion MPT ScsiHost drivers for SAS"
51 depends on PCI && SCSI
54 SCSI HOST support for a SAS host adapters.
56 List of supported controllers:
65 int "Maximum number of scatter gather entries (16 - 128)"
69 This option allows you to specify the maximum number of scatter-
70 gather entries per I/O. The driver default is 128, which matches
71 SCSI_MAX_PHYS_SEGMENTS. However, it may decreased down to 16.
72 Decreasing this parameter will reduce memory requirements
73 on a per controller instance.
76 tristate "Fusion MPT misc device (ioctl) driver"
77 depends on FUSION_SPI || FUSION_FC || FUSION_SAS
79 The Fusion MPT misc device driver provides specialized control
80 of MPT adapters via system ioctl calls. Use of ioctl calls to
81 the MPT driver requires that you create and use a misc device
83 mknod /dev/mptctl c 10 240
85 One use of this ioctl interface is to perform an upgrade (reflash)
86 of the MPT adapter firmware. Refer to readme file(s) distributed
87 with the Fusion MPT linux driver for additional details.
89 If enabled by saying M to this, a driver named: mptctl
92 If unsure whether you really want or need this, say N.
95 tristate "Fusion MPT LAN driver"
96 depends on FUSION_FC && NET_FC
98 This module supports LAN IP traffic over Fibre Channel port(s)
99 on Fusion MPT compatible hardware (LSIFC9xx chips).
100 The physical interface used is defined in RFC 2625.
101 Please refer to that document for details.
103 Installing this driver requires the knowledge to configure and
104 activate a new network interface, "fc0", using standard Linux tools.
106 If enabled by saying M to this, a driver named: mptlan
109 If unsure whether you really want or need this, say N.
111 config FUSION_LOGGING
112 bool "Fusion MPT logging facility"
114 This turns on a logging facility that can be used to debug a number
115 of Fusion MPT related problems.
117 The debug level can be programmed on the fly via SysFS (hex values)
119 echo [level] > /sys/class/scsi_host/host#/debug_level
121 There are various debug levels that can be found in the source:
