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.

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.

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.

79	  Low-level framebuffer-based console driver.

81config FRAMEBUFFER_CONSOLE_LEGACY_ACCELERATION
82	bool "Enable legacy fbcon hardware acceleration code"
83	depends on FRAMEBUFFER_CONSOLE
84	default y if PARISC
85	default n
86	help
87	  This option enables the fbcon (framebuffer text-based) hardware
88	  acceleration for graphics drivers which were written for the fbdev
89	  graphics interface.
90
91	  On modern machines, on mainstream machines (like x86-64) or when
92	  using a modern Linux distribution those fbdev drivers usually aren't used.
93	  So enabling this option wouldn't have any effect, which is why you want
94	  to disable this option on such newer machines.
95
96	  If you compile this kernel for older machines which still require the
97	  fbdev drivers, you may want to say Y.
98
99	  If unsure, select n.
100
101config FRAMEBUFFER_CONSOLE_DETECT_PRIMARY
102       bool "Map the console to the primary display device"
103       depends on FRAMEBUFFER_CONSOLE
104       default n
105	help
106	 If this option is selected, the framebuffer console will
107	 automatically select the primary display device (if the architecture
108	 supports this feature).  Otherwise, the framebuffer console will
109	 always select the first framebuffer driver that is loaded. The latter
110	 is the default behavior.
111
112	 You can always override the automatic selection of the primary device
113	 by using the fbcon=map: boot option.
114
115	 If unsure, select n.
116
117config FRAMEBUFFER_CONSOLE_ROTATION
118       bool "Framebuffer Console Rotation"
119       depends on FRAMEBUFFER_CONSOLE
120       help
121	 Enable display rotation for the framebuffer console.  This is done
122	 in software and may be significantly slower than a normally oriented
123	 display.  Note that the rotation is done at the console level only
124	 such that other users of the framebuffer will remain normally
125	 oriented.
126
127config FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER
128	bool "Framebuffer Console Deferred Takeover"
129	depends on FB=y && FRAMEBUFFER_CONSOLE && DUMMY_CONSOLE
130	help
131	  If enabled this defers the framebuffer console taking over the
132	  console from the dummy console until the first text is displayed on
133	  the console. This is useful in combination with the "quiet" kernel
134	  commandline option to keep the framebuffer contents initially put up
135	  by the firmware in place, rather then replacing the contents with a
136	  black screen as soon as fbcon loads.
137
138config STI_CONSOLE
139	bool "STI text console"
140	depends on PARISC && HAS_IOMEM
141	select FONT_SUPPORT
142	select CRC32
143	default y
144	help
145	  The STI console is the builtin display/keyboard on HP-PARISC
146	  machines.  Say Y here to build support for it into your kernel.
147	  The alternative is to use your primary serial port as a console.
