  20          pSeries machines when partitioned support a hypervisor virtual

 111          Partitionable IBM Power5 ppc64 machines allow hosting of
 112          firmware virtual consoles from one Linux partition by
 113          another Linux partition.  This driver allows console data
 114          from Linux partitions to be accessed through TTY device
 115          interfaces in the device tree of a Linux partition running
 116          this driver.

 118          To compile this driver as a module, choose M here: the
 119          module will be called hvcs.  Additionally, this module
 120          will depend on arch specific APIs exported from hvcserver.ko
 121          which will also be compiled when this driver is built as a
 122          module.
