  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.
 20           To compile this support as a module, choose M here: the
 21           modules will be called i2o_core.
 23           If unsure, say N.
 25 if I2O
 28         bool "Enable LCT notification"
 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.
 38 config 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".
 46 config I2O_EXT_ADAPTEC_DMA64
 47         bool "Enable 64-bit DMA"
 48         depends on I2O_EXT_ADAPTEC && ( 64BIT || HIGHMEM64G )
 49         default y
 50         ---help---
 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.
 55 config I2O_CONFIG
 56         tristate "I2O Configuration support"
 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.
 63           To compile this support as a module, choose M here: the
 64           module will be called i2o_config.
 66           Note: If you want to use the new API you have to download the
 67           i2o_config patch from
 70         bool "Enable ioctls (OBSOLETE)"
 71         depends on I2O_CONFIG
 72         default y
 73         ---help---
 74           Enables old ioctls.
 76 config I2O_BUS
 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.
 86 config 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.
 96           To compile this support as a module, choose M here: the
 97           module will be called i2o_block.
 99 config 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.
108           To compile this support as a module, choose M here: the
109           module will be called i2o_scsi.
111 config I2O_PROC
112         tristate "I2O /proc support"
113         ---help---
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.
118           To compile this support as a module, choose M here: the
119           module will be called i2o_proc.
