1 2menuconfig I2O 3 tristate "I2O device support" 4 depends on PCI 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. 16 17 If you say Y here, you will get a choice of interface adapter 18 drivers and OSM's with the following questions. 19 20 To compile this support as a module, choose M here: the 21 modules will be called i2o_core. 22 23 If unsure, say N. 24 25if I2O 26 27config I2O_LCT_NOTIFY_ON_CHANGES 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. 35 36 If unsure, say Y. 37 38config 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". 45 46config 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. 54 55config 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. 62 63 To compile this support as a module, choose M here: the 64 module will be called i2o_config. 65 66 Note: If you want to use the new API you have to download the 67 i2o_config patch from http://i2o.shadowconnect.com/ 68 69config I2O_CONFIG_OLD_IOCTL 70 bool "Enable ioctls (OBSOLETE)" 71 depends on I2O_CONFIG 72 default y 73 ---help--- 74 Enables old ioctls. 75 76config 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. 82 83 To compile this support as a module, choose M here: the 84 module will be called i2o_bus. 85 86config 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. 95 96 To compile this support as a module, choose M here: the 97 module will be called i2o_block. 98 99config 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. 107 108 To compile this support as a module, choose M here: the 109 module will be called i2o_scsi. 110 111config 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. 117 118 To compile this support as a module, choose M here: the 119 module will be called i2o_proc. 120 121endif # I2O 122
