8config VGA_CONSOLE
9	bool "VGA text console" if EXPERT || !X86
10	depends on !4xx && !PPC_8xx && !SPARC && !M68K && !PARISC &&  !SUPERH && \
11		(!ARM || ARCH_FOOTBRIDGE || ARCH_INTEGRATOR || ARCH_NETWINDER) && \
12		!ARM64 && !ARC && !MICROBLAZE && !OPENRISC && !NDS32 && !S390
13	default y
14	help
15	  Saying Y here will allow you to use Linux in text mode through a
16	  display that complies with the generic VGA standard. Virtually
17	  everyone wants that.
18
19	  The program SVGATextMode can be used to utilize SVGA video cards to
20	  their full potential in text mode. Download it from
21	  <ftp://ibiblio.org/pub/Linux/utils/console/>.
22
23	  Say Y.
24
25config MDA_CONSOLE
26	depends on !M68K && !PARISC && ISA
27	tristate "MDA text console (dual-headed)"
28	help
29	  Say Y here if you have an old MDA or monochrome Hercules graphics
30	  adapter in your system acting as a second head ( = video card). You
31	  will then be able to use two monitors with your Linux system. Do not
32	  say Y here if your MDA card is the primary card in your system; the
33	  normal VGA driver will handle it.
34
35	  To compile this driver as a module, choose M here: the
36	  module will be called mdacon.
37
38	  If unsure, say N.
39
40config SGI_NEWPORT_CONSOLE
41	tristate "SGI Newport Console support"
42	depends on SGI_IP22 && HAS_IOMEM
43	select FONT_SUPPORT
44	help
45	  Say Y here if you want the console on the Newport aka XL graphics
46	  card of your Indy.  Most people say Y here.
47
48config DUMMY_CONSOLE
49	bool
50	default y
51
52config DUMMY_CONSOLE_COLUMNS
53	int "Initial number of console screen columns"
54	depends on DUMMY_CONSOLE && !ARM
55	default 160 if PARISC
56	default 80
57	help
58	  On PA-RISC, the default value is 160, which should fit a 1280x1024
59	  monitor.
60	  Select 80 if you use a 640x480 resolution by default.
61
62config DUMMY_CONSOLE_ROWS
63	int "Initial number of console screen rows"
64	depends on DUMMY_CONSOLE && !ARM
65	default 64 if PARISC
66	default 25
67	help
68	  On PA-RISC, the default value is 64, which should fit a 1280x1024
69	  monitor.
70	  Select 25 if you use a 640x480 resolution by default.
71
72config FRAMEBUFFER_CONSOLE
73	bool "Framebuffer Console support"
74	depends on FB && !UML
75	select VT_HW_CONSOLE_BINDING

77	select FONT_SUPPORT
78	help
79	  Low-level framebuffer-based console driver.

81config FRAMEBUFFER_CONSOLE_DETECT_PRIMARY
82       bool "Map the console to the primary display device"
83       depends on FRAMEBUFFER_CONSOLE
84       default n
85	help
86	 If this option is selected, the framebuffer console will
87	 automatically select the primary display device (if the architecture
88	 supports this feature).  Otherwise, the framebuffer console will
89	 always select the first framebuffer driver that is loaded. The latter
90	 is the default behavior.
91
92	 You can always override the automatic selection of the primary device
93	 by using the fbcon=map: boot option.
94
95	 If unsure, select n.
96
97config FRAMEBUFFER_CONSOLE_ROTATION
98       bool "Framebuffer Console Rotation"
99       depends on FRAMEBUFFER_CONSOLE
100       help
101	 Enable display rotation for the framebuffer console.  This is done
102	 in software and may be significantly slower than a normally oriented
103	 display.  Note that the rotation is done at the console level only
104	 such that other users of the framebuffer will remain normally
105	 oriented.
106
107config FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER
108	bool "Framebuffer Console Deferred Takeover"
109	depends on FB=y && FRAMEBUFFER_CONSOLE && DUMMY_CONSOLE
110	help
111	  If enabled this defers the framebuffer console taking over the
112	  console from the dummy console until the first text is displayed on
113	  the console. This is useful in combination with the "quiet" kernel
114	  commandline option to keep the framebuffer contents initially put up
115	  by the firmware in place, rather then replacing the contents with a
116	  black screen as soon as fbcon loads.
117
118config STI_CONSOLE
119	bool "STI text console"
120	depends on PARISC && HAS_IOMEM
121	select FONT_SUPPORT
122	select CRC32
123	default y
124	help
125	  The STI console is the builtin display/keyboard on HP-PARISC
126	  machines.  Say Y here to build support for it into your kernel.
127	  The alternative is to use your primary serial port as a console.
