5 tristate "Fusion MPT (base + ScsiHost) drivers"
8 LSI Logic Fusion(TM) Message Passing Technology (MPT) device support
9 provides high performance SCSI host initiator, and LAN [1] interface
10 services to a host system. The Fusion architecture is capable of
11 duplexing these protocols on high-speed Fibre Channel
12 (up to 2 GHz x 2 ports = 4 GHz) and parallel SCSI (up to Ultra-320)
15 [1] LAN is not supported on parallel SCSI medium.
18 int "Maximum number of scatter gather entries"
22 This option allows you to specify the maximum number of scatter-
23 gather entries per I/O. The driver defaults to 40, a reasonable number
24 for most systems. However, the user may increase this up to 128.
25 Increasing this parameter will require significantly more memory
26 on a per controller instance. Increasing the parameter is not
27 necessary (or recommended) unless the user will be running
28 large I/O's via the raw interface.
31 tristate "Enhanced SCSI error reporting"
32 depends on MODULES && FUSION && m
34 The isense module (roughly stands for Interpret SENSE data) is
35 completely optional. It simply provides extra English readable
36 strings in SCSI Error Report(s) that might be generated from the
37 Fusion MPT SCSI Host driver, for example when a target device
38 returns a SCSI check condition on a I/O. Without this module
41 SCSI Error Report =-=-= (ioc0,scsi5:0)
42 SCSI_Status=02h (CHECK_CONDITION)
43 Original_CDB[]: 2A 00 00 00 00 41 00 00 02 00
44 SenseData[12h]: 70 00 02 00 00 00 00 0A 00 00 00 00 04 02 02 00 00 00
45 SenseKey=2h (NOT READY); FRU=02h
48 Where otherwise, if this module had been loaded, you would see:
50 SCSI Error Report =-=-= (ioc0,scsi5:0)
51 SCSI_Status=02h (CHECK_CONDITION)
52 Original_CDB[]: 2A 00 00 00 00 41 00 00 02 00 - "WRITE(10)"
53 SenseData[12h]: 70 00 02 00 00 00 00 0A 00 00 00 00 04 02 02 00 00 00
54 SenseKey=2h (NOT READY); FRU=02h
55 ASC/ASCQ=29h/00h "LOGICAL UNIT NOT READY, INITIALIZING CMD. REQUIRED"
57 Say M for "Enhanced SCSI error reporting" to compile this optional module,
58 creating a driver named: isense.
60 NOTE: Support for building this feature into the kernel is not
61 available, due to kernel size considerations.
64 tristate "Fusion MPT misc device (ioctl) driver"
65 depends on MODULES && FUSION && m
67 The Fusion MPT misc device driver provides specialized control
68 of MPT adapters via system ioctl calls. Use of ioctl calls to
69 the MPT driver requires that you create and use a misc device
71 mknod /dev/mptctl c 10 240
73 One use of this ioctl interface is to perform an upgrade (reflash)
74 of the MPT adapter firmware. Refer to readme file(s) distributed
75 with the Fusion MPT linux driver for additional details.
77 If enabled by saying M to this, a driver named: mptctl
80 If unsure whether you really want or need this, say N.
83 tristate "Fusion MPT LAN driver"
84 depends on FUSION && NET_FC
86 This module supports LAN IP traffic over Fibre Channel port(s)
87 on Fusion MPT compatible hardware (LSIFC9xx chips).
88 The physical interface used is defined in RFC 2625.
89 Please refer to that document for details.
91 Installing this driver requires the knowledge to configure and
92 activate a new network interface, "fc0", using standard Linux tools.
94 If enabled by saying M to this, a driver named: mptlan
97 If unsure whether you really want or need this, say N.
