353 tristate "Support for CHSC subchannels"
354 help
355 This driver allows usage of CHSC subchannels. A CHSC subchannel
356 is usually present on LPAR only.
357 The driver creates a device /dev/chsc, which may be used to
358 obtain I/O configuration information about the machine and
359 to issue asynchronous chsc commands (DANGEROUS).
360 You will usually only want to use this interface on a special
361 LPAR designated for system management.
362
363 To compile this driver as a module, choose M here: the
364 module will be called chsc_sch.
