tristate "I2O support"
|
|
depends on PCI
|
|
---help---
|
|
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.
|
|
|
|
config I2O_LCT_NOTIFY_ON_CHANGES
|
|
bool "Enable LCT notification"
|
|
depends on I2O
|
|
default y
|
|
---help---
|
|
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.
|
|
|
|
config I2O_EXT_ADAPTEC
|
|
bool "Enable Adaptec extensions"
|
|
depends on I2O
|
|
default y
|
|
---help---
|
|
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".
|
|
|
|
config I2O_EXT_ADAPTEC_DMA64
|
|
bool "Enable 64-bit DMA"
|
|
depends on I2O_EXT_ADAPTEC && ( 64BIT || HIGHMEM64G )
|
|
default y
|
|
---help---
|
|
Say Y for support of 64-bit DMA transfer mode on Adaptec I2O
|
|
controllers.
|
|
Note: You need at least firmware version 3709.
|
|
|
|
config I2O_CONFIG
|
|
tristate "I2O Configuration support"
|
|
depends on I2O
|
|
---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.
|
|
|
|
Note: If you want to use the new API you have to download the
|
|
i2o_config patch from http://i2o.shadowconnect.com/
|
|
|
|
config I2O_CONFIG_OLD_IOCTL
|
|
bool "Enable ioctls (OBSOLETE)"
|
|
depends on I2O_CONFIG
|
|
default y
|
|
---help---
|
|
Enables old ioctls.
|
|
|
|
config I2O_BUS
|
|
tristate "I2O Bus Adapter OSM"
|
|
depends on I2O
|
|
---help---
|
|
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.
|
|
|
|
To compile this support as a module, choose M here: the
|
|
module will be called i2o_bus.
|
|
|
|
config I2O_BLOCK
|
|
tristate "I2O Block OSM"
|
|
depends on I2O
|
|
---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.
|
|
|
|
config I2O_SCSI
|
|
tristate "I2O SCSI OSM"
|
|
depends on I2O && SCSI
|
|
---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.
|
|
|
|
To compile this support as a module, choose M here: the
|
|
module will be called i2o_scsi.
|
|
|
|
config I2O_PROC
|
|
tristate "I2O /proc support"
|
|
depends on I2O
|
|
---help---
|
|
If you say Y here and to "/proc file system support", you will be
|
|
able to read I2O related information from the virtual directory
|
|
/proc/i2o.
|
|
|
|
To compile this support as a module, choose M here: the
|
|
module will be called i2o_proc.
