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.
