help
Generic "hypervisor virtual console" infrastructure for various
hypervisors (pSeries, iSeries, Xen, lguest).
It will automatically be selected if one of the back-end console drivers
is selected.

help
pSeries machines when partitioned support a hypervisor virtual
console. This driver allows each pSeries partition to have a console
which is accessed via the HMC.

This driver provides a Hypervisor console (HVC) back-end to access
a Linux (console) terminal via a z/VM IUCV communication path.

help
This is meant to be used during HW bring up or debugging when
no other console mechanism exist but udbg, to get you a quick
console for userspace. Do NOT enable in production kernels.
config HVC_DCC

select HVC_DRIVER
help
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
a JTAG then you probably don't want this option.
config HVC_BFIN_JTAG
bool "Blackfin JTAG console"
depends on BLACKFIN
select HVC_DRIVER
help
This console uses the Blackfin JTAG to create a console under the
the HVC driver. If you don't have JTAG, then you probably don't
want this option.
config HVCS
tristate "IBM Hypervisor Virtual Console Server support"
depends on PPC_PSERIES && HVC_CONSOLE
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.
