2	tristate "I2O device support"
3	depends on PCI
4	---help---
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.
15
16	  If you say Y here, you will get a choice of interface adapter
17	  drivers and OSM's with the following questions.
18
19	  To compile this support as a module, choose M here: the
20	  modules will be called i2o_core.
21
22	  If unsure, say N.

26config I2O_LCT_NOTIFY_ON_CHANGES
27	bool "Enable LCT notification"
28	default y
29	---help---
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.
34
35	  If unsure, say Y.
36
37config I2O_EXT_ADAPTEC
38	bool "Enable Adaptec extensions"
39	default y
40	---help---
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".
44
45config I2O_EXT_ADAPTEC_DMA64
46	bool "Enable 64-bit DMA"
47	depends on I2O_EXT_ADAPTEC && ( 64BIT || HIGHMEM64G )
48	default y
49	---help---
50	  Say Y for support of 64-bit DMA transfer mode on Adaptec I2O
51	  controllers.
52	  Note: You need at least firmware version 3709.
53
54config I2O_CONFIG
55	tristate "I2O Configuration support"
56	depends on VIRT_TO_BUS
57	---help---
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.
61
62	  To compile this support as a module, choose M here: the
63	  module will be called i2o_config.
64
65	  Note: If you want to use the new API you have to download the
66	  i2o_config patch from http://i2o.shadowconnect.com/
67
68config I2O_CONFIG_OLD_IOCTL
69	bool "Enable ioctls (OBSOLETE)"
70	depends on I2O_CONFIG
71	default y
72	---help---
73	  Enables old ioctls.
74
75config I2O_BUS
76	tristate "I2O Bus Adapter OSM"
77	---help---
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.
81
82	  To compile this support as a module, choose M here: the
83	  module will be called i2o_bus.
84
85config I2O_BLOCK
86	tristate "I2O Block OSM"
87	depends on BLOCK
88	---help---
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.
94
95	  To compile this support as a module, choose M here: the
96	  module will be called i2o_block.
97
98config I2O_SCSI
99	tristate "I2O SCSI OSM"
100	depends on SCSI
101	---help---
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.
106
107	  To compile this support as a module, choose M here: the
108	  module will be called i2o_scsi.
109
110config I2O_PROC
111	tristate "I2O /proc support"
112	---help---
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
115	  /proc/i2o.
116
117	  To compile this support as a module, choose M here: the
118	  module will be called i2o_proc.
