Available only if 3270 support is compiled in statically. config TN3215 def_bool y prompt "Support for 3215 line mode terminal" depends on CCW && TTY help Include support for IBM 3215 line-mode terminals. config TN3215_CONSOLE def_bool y prompt "Support for console on 3215 line mode terminal" depends on TN3215 help Include support for using an IBM 3215 line-mode terminal as a Linux system console. config CCW_CONSOLE def_bool y if TN3215_CONSOLE || TN3270_CONSOLE config SCLP_TTY def_bool y prompt "Support for SCLP line mode terminal" depends on S390 && TTY help Include support for IBM SCLP line-mode terminals. config SCLP_CONSOLE def_bool y prompt "Support for console on SCLP line mode terminal" depends on SCLP_TTY help Include support for using an IBM HWC line-mode terminal as the Linux system console. config SCLP_VT220_TTY def_bool y prompt "Support for SCLP VT220-compatible terminal" depends on S390 && TTY help Include support for an IBM SCLP VT220-compatible terminal. config SCLP_VT220_CONSOLE def_bool y prompt "Support for console on SCLP VT220-compatible terminal" depends on SCLP_VT220_TTY help Include support for using an IBM SCLP VT220-compatible terminal as a Linux system console. config HMC_DRV def_tristate m prompt "Support for file transfers from HMC drive CD/DVD-ROM" depends on S390 select CRC16 help This option enables support for file transfers from a Hardware Management Console (HMC) drive CD/DVD-ROM. It is available as a module, called 'hmcdrv', and also as kernel built-in. There is one optional parameter for this module: cachesize=N, which modifies the transfer cache size from it's default value 0.5MB to N bytes. If N is zero, then no caching is performed. config SCLP_OFB def_bool n prompt "Support for Open-for-Business SCLP Event" depends on S390 help This option enables the Open-for-Business interface to the s390 Service Element. config S390_UV_UAPI def_tristate m prompt "Ultravisor userspace API" depends on S390 help Selecting exposes parts of the UV interface to userspace by providing a misc character device at /dev/uv. Using IOCTLs one can interact with the UV. The device is only available if the Ultravisor Facility (158) is present. config S390_TAPE def_tristate m prompt "S/390 tape device support" depends on CCW help Select this option if you want to access channel-attached tape devices on IBM S/390 or zSeries. If you select this option you will also want to select at least one of the tape interface options and one of the tape hardware options in order to access a tape device. This option is also available as a module. The module will be called tape390 and include all selected interfaces and hardware drivers. comment "S/390 tape hardware support" depends on S390_TAPE config S390_TAPE_34XX def_tristate m prompt "Support for 3480/3490 tape hardware" depends on S390_TAPE help Select this option if you want to access IBM 3480/3490 magnetic tape subsystems and 100% compatibles.
