2 menu "I2O device support"
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.
19 If you say Y here, you will get a choice of interface adapter
20 drivers and OSM's with the following questions.
22 To compile this support as a module, choose M here: the
23 modules will be called i2o_core.
28 tristate "I2O Configuration support"
31 Say Y for support of the configuration interface for the I2O adapters.
32 If you have a RAID controller from Adaptec and you want to use the
33 raidutils to manage your RAID array, you have to say Y here.
35 To compile this support as a module, choose M here: the
36 module will be called i2o_config.
38 config I2O_CONFIG_OLD_IOCTL
39 bool "Enable ioctls (OBSOLETE)"
46 tristate "I2O Bus Adapter OSM"
49 Include support for the I2O Bus Adapter OSM. The Bus Adapter OSM
50 provides access to the busses on the I2O controller. The main purpose
51 is to rescan the bus to find new devices.
53 To compile this support as a module, choose M here: the
54 module will be called i2o_bus.
57 tristate "I2O Block OSM"
60 Include support for the I2O Block OSM. The Block OSM presents disk
61 and other structured block devices to the operating system. If you
62 are using an RAID controller, you could access the array only by
63 the Block OSM driver. But it is possible to access the single disks
64 by the SCSI OSM driver, for example to monitor the disks.
66 To compile this support as a module, choose M here: the
67 module will be called i2o_block.
70 tristate "I2O SCSI OSM"
71 depends on I2O && SCSI
73 Allows direct SCSI access to SCSI devices on a SCSI or FibreChannel
74 I2O controller. You can use both the SCSI and Block OSM together if
75 you wish. To access a RAID array, you must use the Block OSM driver.
76 But you could use the SCSI OSM driver to monitor the single disks.
78 To compile this support as a module, choose M here: the
79 module will be called i2o_scsi.
82 tristate "I2O /proc support"
85 If you say Y here and to "/proc file system support", you will be
86 able to read I2O related information from the virtual directory
89 To compile this support as a module, choose M here: the
90 module will be called i2o_proc.
