| config I2O |
| 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_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. |
| |
| 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. |
