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
29 bool "OPAL Console support"
30 depends on PPC_POWERNV
35 PowerNV machines running under OPAL need that driver to get a console
38 bool "IBM RTAS Console support"
42 IBM Console device driver which makes use of RTAS
45 bool "z/VM IUCV Hypervisor console support (VM only)"
46 depends on S390 && NET
51 This driver provides a Hypervisor console (HVC) back-end to access
52 a Linux (console) terminal via a z/VM IUCV communication path.
55 bool "Xen Hypervisor Console support"
61 Xen virtual console device driver
63 config HVC_XEN_FRONTEND
64 bool "Xen Hypervisor Multiple Consoles support"
66 select XEN_XENBUS_FRONTEND
69 Xen driver for secondary virtual consoles
72 bool "udbg based fake hypervisor console"
76 This is meant to be used during HW bring up or debugging when
77 no other console mechanism exist but udbg, to get you a quick
78 console for userspace. Do NOT enable in production kernels.
81 bool "ARM JTAG DCC console"
82 depends on ARM || ARM64
85 This console uses the JTAG DCC on ARM to create a console under the HVC
86 driver. This console is used through a JTAG only on ARM. If you don't have
87 a JTAG then you probably don't want this option.
90 bool "RISC-V SBI console support"
91 depends on RISCV_SBI_V01
94 This enables support for console output via RISC-V SBI calls, which
95 is normally used only during boot to output printk.
97 If you don't know what do to here, say Y.
100 tristate "IBM Hypervisor Virtual Console Server support"
101 depends on PPC_PSERIES && HVC_CONSOLE
103 Partitionable IBM Power5 ppc64 machines allow hosting of
104 firmware virtual consoles from one Linux partition by
105 another Linux partition. This driver allows console data
106 from Linux partitions to be accessed through TTY device
107 interfaces in the device tree of a Linux partition running
110 To compile this driver as a module, choose M here: the
111 module will be called hvcs. Additionally, this module
112 will depend on arch specific APIs exported from hvcserver.ko
113 which will also be compiled when this driver is built as a
