+ help
+ This driver allows usage of CHSC subchannels. A CHSC subchannel
+ is usually present on LPAR only.
+ The driver creates a device /dev/chsc, which may be used to
+ obtain I/O configuration information about the machine and
+ to issue asynchronous chsc commands (DANGEROUS).
+ You will usually only want to use this interface on a special
+ LPAR designated for system management.
+
+ To compile this driver as a module, choose M here: the
+ module will be called chsc_sch.
+
+ If unsure, say N.
