6 Generic "hypervisor virtual console" infrastructure for various
7 hypervisors (pSeries, iSeries, Xen).
8 It will automatically be selected if one of the back-end console drivers
15 bool "pSeries Hypervisor Virtual Console support"
16 depends on PPC_PSERIES
20 pSeries machines when partitioned support a hypervisor virtual
21 console. This driver allows each pSeries partition to have a console
22 which is accessed via the HMC.
25 bool "Old driver for pSeries serial port (/dev/hvsi*)"
26 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"
78 This is meant to be used during HW bring up or debugging when
79 no other console mechanism exist but udbg, to get you a quick
80 console for userspace. Do NOT enable in production kernels.
83 bool "ARM JTAG DCC console"
84 depends on ARM || ARM64
87 This console uses the JTAG DCC on ARM to create a console under the HVC
88 driver. This console is used through a JTAG only on ARM. If you don't have
89 a JTAG then you probably don't want this option.
92 bool "RISC-V SBI console support"
96 This enables support for console output via RISC-V SBI calls, which
97 is normally used only during boot to output printk.
99 If you don't know what do to here, say Y.
102 tristate "IBM Hypervisor Virtual Console Server support"
103 depends on PPC_PSERIES && HVC_CONSOLE
105 Partitionable IBM Power5 ppc64 machines allow hosting of
106 firmware virtual consoles from one Linux partition by
107 another Linux partition. This driver allows console data
108 from Linux partitions to be accessed through TTY device
109 interfaces in the device tree of a Linux partition running
112 To compile this driver as a module, choose M here: the
113 module will be called hvcs. Additionally, this module
114 will depend on arch specific APIs exported from hvcserver.ko
115 which will also be compiled when this driver is built as a
