The Intelligent Input/Output (I2O) architecture allows hardware
|
||
|
|
drivers to be split into two parts: an operating system specific
|
||
|
|
module called the OSM and an hardware specific module called the
|
||
|
|
HDM. The OSM can talk to a whole range of HDM's, and ideally the
|
||
|
|
HDM's are not OS dependent. This allows for the same HDM driver to
|
||
|
|
be used under different operating systems if the relevant OSM is in
|
||
|
|
place. In order for this to work, you need to have an I2O interface
|
||
|
|
adapter card in your computer. This card contains a special I/O
|
||
|
|
processor (IOP), thus allowing high speeds since the CPU does not
|
||
|
|
have to deal with I/O.
|
||
|
|
|
||
|
|
If you say Y here, you will get a choice of interface adapter
|
||
|
|
drivers and OSM's with the following questions.
|
||
|
|
|
||
|
|
To compile this support as a module, choose M here: the
|
||
|
|
modules will be called i2o_core.
|
||
|
|
|
||
|
|
If unsure, say N.

|

Only say N here if you have a I2O controller from SUN. The SUN
|
||
|
|
firmware doesn't support LCT notification on changes. If this option
|
||
|
|
is enabled on such a controller the driver will hang up in a endless
|
||
|
|
loop. On all other controllers say Y.
|

If unsure, say Y.

Say Y for support of raidutils for Adaptec I2O controllers. You also
|

|
|
have to say Y to "I2O Configuration support", "I2O SCSI OSM" below
|

and to "SCSI generic support" under "SCSI device configuration".

|

|
|
Say Y for support of 64-bit DMA transfer mode on Adaptec I2O
|

controllers.

Note: You need at least firmware version 3709.

---help---
|

Say Y for support of the configuration interface for the I2O adapters.
|
||
|
|
If you have a RAID controller from Adaptec and you want to use the
|
||
|
|
raidutils to manage your RAID array, you have to say Y here.
|
||
|
|
|

To compile this support as a module, choose M here: the

module will be called i2o_config.

|

Include support for the I2O Bus Adapter OSM. The Bus Adapter OSM
|
||
|
|
provides access to the busses on the I2O controller. The main purpose
|
||
|
|
is to rescan the bus to find new devices.

---help---
|

Include support for the I2O Block OSM. The Block OSM presents disk
|
||
|
|
and other structured block devices to the operating system. If you
|
||
|
|
are using an RAID controller, you could access the array only by
|
||
|
|
the Block OSM driver. But it is possible to access the single disks
|
||
|
|
by the SCSI OSM driver, for example to monitor the disks.
|

To compile this support as a module, choose M here: the

module will be called i2o_block.

---help---
|

Allows direct SCSI access to SCSI devices on a SCSI or FibreChannel
|

|
I2O controller. You can use both the SCSI and Block OSM together if
|
||
|
|
you wish. To access a RAID array, you must use the Block OSM driver.
|

But you could use the SCSI OSM driver to monitor the single disks.
