| tristate "I2O device 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. | |
| if I2O | |
| config I2O_LCT_NOTIFY_ON_CHANGES | |
| bool "Enable LCT notification" | |
| 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" | |
| 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 VIRT_TO_BUS | |
| ---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" | |
| ---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 BLOCK | |
| ---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 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" | |
| ---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. | |
