3 tristate "I2O device support"
4 depends on PCI
5 ---help---
6 The Intelligent Input/Output (I2O) architecture allows hardware
7 drivers to be split into two parts: an operating system specific
8 module called the OSM and an hardware specific module called the
9 HDM. The OSM can talk to a whole range of HDM's, and ideally the
10 HDM's are not OS dependent. This allows for the same HDM driver to
11 be used under different operating systems if the relevant OSM is in
12 place. In order for this to work, you need to have an I2O interface
13 adapter card in your computer. This card contains a special I/O
14 processor (IOP), thus allowing high speeds since the CPU does not
15 have to deal with I/O.

17 If you say Y here, you will get a choice of interface adapter
18 drivers and OSM's with the following questions.
19
20 To compile this support as a module, choose M here: the
21 modules will be called i2o_core.
22
23 If unsure, say N.

27config I2O_LCT_NOTIFY_ON_CHANGES

29 default y
30 ---help---
31 Only say N here if you have a I2O controller from SUN. The SUN
32 firmware doesn't support LCT notification on changes. If this option
33 is enabled on such a controller the driver will hang up in a endless
34 loop. On all other controllers say Y.

36 If unsure, say Y.

38config I2O_EXT_ADAPTEC
39 bool "Enable Adaptec extensions"
40 default y
41 ---help---
42 Say Y for support of raidutils for Adaptec I2O controllers. You also
43 have to say Y to "I2O Configuration support", "I2O SCSI OSM" below
44 and to "SCSI generic support" under "SCSI device configuration".

51 Say Y for support of 64-bit DMA transfer mode on Adaptec I2O
52 controllers.
53 Note: You need at least firmware version 3709.

57 depends on VIRT_TO_BUS
58 ---help---
59 Say Y for support of the configuration interface for the I2O adapters.
60 If you have a RAID controller from Adaptec and you want to use the
61 raidutils to manage your RAID array, you have to say Y here.
62
63 To compile this support as a module, choose M here: the
64 module will be called i2o_config.
65
66 Note: If you want to use the new API you have to download the
67 i2o_config patch from http://i2o.shadowconnect.com/

77 tristate "I2O Bus Adapter OSM"
78 ---help---
79 Include support for the I2O Bus Adapter OSM. The Bus Adapter OSM
80 provides access to the busses on the I2O controller. The main purpose
81 is to rescan the bus to find new devices.

83 To compile this support as a module, choose M here: the
84 module will be called i2o_bus.
85
86config I2O_BLOCK
87 tristate "I2O Block OSM"
88 depends on BLOCK
89 ---help---
90 Include support for the I2O Block OSM. The Block OSM presents disk
91 and other structured block devices to the operating system. If you
92 are using an RAID controller, you could access the array only by
93 the Block OSM driver. But it is possible to access the single disks
94 by the SCSI OSM driver, for example to monitor the disks.
95
96 To compile this support as a module, choose M here: the
97 module will be called i2o_block.
98
99config I2O_SCSI
100 tristate "I2O SCSI OSM"
101 depends on SCSI
102 ---help---
103 Allows direct SCSI access to SCSI devices on a SCSI or FibreChannel
104 I2O controller. You can use both the SCSI and Block OSM together if
105 you wish. To access a RAID array, you must use the Block OSM driver.
106 But you could use the SCSI OSM driver to monitor the single disks.
107
108 To compile this support as a module, choose M here: the
109 module will be called i2o_scsi.
110
111config I2O_PROC
112 tristate "I2O /proc support"

114 If you say Y here and to "/proc file system support", you will be
115 able to read I2O related information from the virtual directory
116 /proc/i2o.
