7 Generic "hypervisor virtual console" infrastructure for various
8 hypervisors (pSeries, iSeries, Xen).
9 It will automatically be selected if one of the back-end console drivers
16 bool "pSeries Hypervisor Virtual Console support"
17 depends on PPC_PSERIES
21 pSeries machines when partitioned support a hypervisor virtual
22 console. This driver allows each pSeries partition to have a console
23 which is accessed via the HMC.
26 bool "Old driver for pSeries serial port (/dev/hvsi*)"
27 depends on HVC_CONSOLE
30 bool "OPAL Console support"
31 depends on PPC_POWERNV
36 PowerNV machines running under OPAL need that driver to get a console
39 bool "IBM RTAS Console support"
43 IBM Console device driver which makes use of RTAS
46 bool "z/VM IUCV Hypervisor console support (VM only)"
47 depends on S390 && NET
52 This driver provides a Hypervisor console (HVC) back-end to access
53 a Linux (console) terminal via a z/VM IUCV communication path.
56 bool "Xen Hypervisor Console support"
62 Xen virtual console device driver
64 config HVC_XEN_FRONTEND
65 bool "Xen Hypervisor Multiple Consoles support"
67 select XEN_XENBUS_FRONTEND
70 Xen driver for secondary virtual consoles
73 bool "udbg based fake hypervisor console"
77 This is meant to be used during HW bring up or debugging when
78 no other console mechanism exist but udbg, to get you a quick
79 console for userspace. Do NOT enable in production kernels.
82 bool "ARM JTAG DCC console"
83 depends on ARM || ARM64
86 This console uses the JTAG DCC on ARM to create a console under the HVC
87 driver. This console is used through a JTAG only on ARM. If you don't have
88 a JTAG then you probably don't want this option.
91 bool "RISC-V SBI console support"
95 This enables support for console output via RISC-V SBI calls, which
96 is normally used only during boot to output printk.
98 If you don't know what do to here, say Y.
101 tristate "IBM Hypervisor Virtual Console Server support"
102 depends on PPC_PSERIES && HVC_CONSOLE
104 Partitionable IBM Power5 ppc64 machines allow hosting of
105 firmware virtual consoles from one Linux partition by
106 another Linux partition. This driver allows console data
107 from Linux partitions to be accessed through TTY device
108 interfaces in the device tree of a Linux partition running
111 To compile this driver as a module, choose M here: the
112 module will be called hvcs. Additionally, this module
113 will depend on arch specific APIs exported from hvcserver.ko
114 which will also be compiled when this driver is built as a
