console for userspace. Do NOT enable in production kernels. |

This console uses the JTAG DCC on ARM to create a console under the HVC |

driver. This console is used through a JTAG only on ARM. If you don't have |

help |
|
Partitionable IBM Power5 ppc64 machines allow hosting of |
|
firmware virtual consoles from one Linux partition by |
|
another Linux partition. This driver allows console data |
|
from Linux partitions to be accessed through TTY device |
|
interfaces in the device tree of a Linux partition running |
|
this driver. |
|
|
|
To compile this driver as a module, choose M here: the |
|
module will be called hvcs. Additionally, this module |
|
will depend on arch specific APIs exported from hvcserver.ko |
|
which will also be compiled when this driver is built as a |
|
module.
