8 ---help---
9 The Intelligent Input/Output (I2O) architecture allows hardware
10 drivers to be split into two parts: an operating system specific
11 module called the OSM and an hardware specific module called the
12 HDM. The OSM can talk to a whole range of HDM's, and ideally the
13 HDM's are not OS dependent. This allows for the same HDM driver to
14 be used under different operating systems if the relevant OSM is in
15 place. In order for this to work, you need to have an I2O interface
16 adapter card in your computer. This card contains a special I/O
17 processor (IOP), thus allowing high speeds since the CPU does not
18 have to deal with I/O.
19
20 If you say Y here, you will get a choice of interface adapter
21 drivers and OSM's with the following questions.
22
23 To compile this support as a module, choose M here: the
24 modules will be called i2o_core.
25
26 If unsure, say N.
27
28config I2O_LCT_NOTIFY_ON_CHANGES
29 bool "Enable LCT notification"
30 depends on I2O
31 default y
32 ---help---
33 Only say N here if you have a I2O controller from SUN. The SUN
34 firmware doesn't support LCT notification on changes. If this option
35 is enabled on such a controller the driver will hang up in a endless
36 loop. On all other controllers say Y.
37
38 If unsure, say Y.
39
40config I2O_EXT_ADAPTEC
41 bool "Enable Adaptec extensions"
42 depends on I2O
43 default y
44 ---help---
45 Say Y for support of raidutils for Adaptec I2O controllers. You also
46 have to say Y to "I2O Configuration support", "I2O SCSI OSM" below
47 and to "SCSI generic support" under "SCSI device configuration".
48
49config I2O_EXT_ADAPTEC_DMA64
50 bool "Enable 64-bit DMA"
51 depends on I2O_EXT_ADAPTEC && ( 64BIT || HIGHMEM64G )
52 default y
53 ---help---
54 Say Y for support of 64-bit DMA transfer mode on Adaptec I2O
55 controllers.
56 Note: You need at least firmware version 3709.
57
58config I2O_CONFIG
59 tristate "I2O Configuration support"
60 depends on I2O
61 ---help---
62 Say Y for support of the configuration interface for the I2O adapters.
63 If you have a RAID controller from Adaptec and you want to use the
64 raidutils to manage your RAID array, you have to say Y here.
65
66 To compile this support as a module, choose M here: the
67 module will be called i2o_config.
68
69 Note: If you want to use the new API you have to download the
70 i2o_config patch from http://i2o.shadowconnect.com/
71
72config I2O_CONFIG_OLD_IOCTL
73 bool "Enable ioctls (OBSOLETE)"
74 depends on I2O_CONFIG
75 default y
76 ---help---
77 Enables old ioctls.
78
79config I2O_BUS
80 tristate "I2O Bus Adapter OSM"
81 depends on I2O
82 ---help---
83 Include support for the I2O Bus Adapter OSM. The Bus Adapter OSM
84 provides access to the busses on the I2O controller. The main purpose
85 is to rescan the bus to find new devices.
86
87 To compile this support as a module, choose M here: the
88 module will be called i2o_bus.
89
90config I2O_BLOCK
91 tristate "I2O Block OSM"
92 depends on I2O && BLOCK
93 ---help---
94 Include support for the I2O Block OSM. The Block OSM presents disk
95 and other structured block devices to the operating system. If you
96 are using an RAID controller, you could access the array only by
97 the Block OSM driver. But it is possible to access the single disks
98 by the SCSI OSM driver, for example to monitor the disks.
99
100 To compile this support as a module, choose M here: the
101 module will be called i2o_block.
102
103config I2O_SCSI
104 tristate "I2O SCSI OSM"
105 depends on I2O && SCSI
106 ---help---
107 Allows direct SCSI access to SCSI devices on a SCSI or FibreChannel
108 I2O controller. You can use both the SCSI and Block OSM together if
109 you wish. To access a RAID array, you must use the Block OSM driver.
110 But you could use the SCSI OSM driver to monitor the single disks.
111
112 To compile this support as a module, choose M here: the
113 module will be called i2o_scsi.
114
115config I2O_PROC
116 tristate "I2O /proc support"
117 depends on I2O
118 ---help---
119 If you say Y here and to "/proc file system support", you will be
120 able to read I2O related information from the virtual directory
121 /proc/i2o.
122
123 To compile this support as a module, choose M here: the
124 module will be called i2o_proc.
