4config I2O
5 tristate "I2O support"
6 depends on PCI
7 ---help---
8 The Intelligent Input/Output (I2O) architecture allows hardware
9 drivers to be split into two parts: an operating system specific
10 module called the OSM and an hardware specific module called the
11 HDM. The OSM can talk to a whole range of HDM's, and ideally the
12 HDM's are not OS dependent. This allows for the same HDM driver to
13 be used under different operating systems if the relevant OSM is in
14 place. In order for this to work, you need to have an I2O interface
15 adapter card in your computer. This card contains a special I/O
16 processor (IOP), thus allowing high speeds since the CPU does not
17 have to deal with I/O.
18
19 If you say Y here, you will get a choice of interface adapter
20 drivers and OSM's with the following questions.
21
22 To compile this support as a module, choose M here: the
23 modules will be called i2o_core.
24
25 If unsure, say N.
26
27config I2O_LCT_NOTIFY_ON_CHANGES
28 bool "Enable LCT notification"
29 depends on I2O
30 default y
31 ---help---
32 Only say N here if you have a I2O controller from SUN. The SUN
33 firmware doesn't support LCT notification on changes. If this option
34 is enabled on such a controller the driver will hang up in a endless
35 loop. On all other controllers say Y.
36
37 If unsure, say Y.
38
39config I2O_EXT_ADAPTEC
40 bool "Enable Adaptec extensions"
41 depends on I2O
42 default y
43 ---help---
44 Say Y for support of raidutils for Adaptec I2O controllers. You also
45 have to say Y to "I2O Configuration support", "I2O SCSI OSM" below
46 and to "SCSI generic support" under "SCSI device configuration".
47
48config I2O_EXT_ADAPTEC_DMA64
49 bool "Enable 64-bit DMA"
50 depends on I2O_EXT_ADAPTEC && ( 64BIT || HIGHMEM64G )
51 default y
52 ---help---
53 Say Y for support of 64-bit DMA transfer mode on Adaptec I2O
54 controllers.
55 Note: You need at least firmware version 3709.
56
57config I2O_CONFIG
58 tristate "I2O Configuration support"
59 depends on I2O
60 ---help---
61 Say Y for support of the configuration interface for the I2O adapters.
62 If you have a RAID controller from Adaptec and you want to use the
63 raidutils to manage your RAID array, you have to say Y here.
64
65 To compile this support as a module, choose M here: the
66 module will be called i2o_config.
67
68 Note: If you want to use the new API you have to download the
69 i2o_config patch from http://i2o.shadowconnect.com/
70
71config I2O_CONFIG_OLD_IOCTL
72 bool "Enable ioctls (OBSOLETE)"
73 depends on I2O_CONFIG
74 default y
75 ---help---
76 Enables old ioctls.
77
78config I2O_BUS
79 tristate "I2O Bus Adapter OSM"
80 depends on I2O
81 ---help---
82 Include support for the I2O Bus Adapter OSM. The Bus Adapter OSM
83 provides access to the busses on the I2O controller. The main purpose
84 is to rescan the bus to find new devices.
85
86 To compile this support as a module, choose M here: the
87 module will be called i2o_bus.
88
89config I2O_BLOCK
90 tristate "I2O Block OSM"
91 depends on I2O && BLOCK
92 ---help---
93 Include support for the I2O Block OSM. The Block OSM presents disk
94 and other structured block devices to the operating system. If you
95 are using an RAID controller, you could access the array only by
96 the Block OSM driver. But it is possible to access the single disks
97 by the SCSI OSM driver, for example to monitor the disks.
98
99 To compile this support as a module, choose M here: the
100 module will be called i2o_block.
101
102config I2O_SCSI
103 tristate "I2O SCSI OSM"
104 depends on I2O && SCSI
105 ---help---
106 Allows direct SCSI access to SCSI devices on a SCSI or FibreChannel
107 I2O controller. You can use both the SCSI and Block OSM together if
108 you wish. To access a RAID array, you must use the Block OSM driver.
109 But you could use the SCSI OSM driver to monitor the single disks.
110
111 To compile this support as a module, choose M here: the
112 module will be called i2o_scsi.
113
114config I2O_PROC
115 tristate "I2O /proc support"
116 depends on I2O
117 ---help---
118 If you say Y here and to "/proc file system support", you will be
119 able to read I2O related information from the virtual directory
120 /proc/i2o.
121
122 To compile this support as a module, choose M here: the
123 module will be called i2o_proc.
