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