7config VGA_CONSOLE
8	bool "VGA text console" if EMBEDDED || !X86
9	depends on !ARCH_ACORN && !ARCH_EBSA110 && !4xx && !8xx && !SPARC && !M68K && !PARISC && !FRV && !ARCH_VERSATILE && !SUPERH
10	default y
11	help
12	  Saying Y here will allow you to use Linux in text mode through a
13	  display that complies with the generic VGA standard. Virtually
14	  everyone wants that.
15
16	  The program SVGATextMode can be used to utilize SVGA video cards to
17	  their full potential in text mode. Download it from
18	  <ftp://ibiblio.org/pub/Linux/utils/console/>.
19
20	  Say Y.

22config VGACON_SOFT_SCROLLBACK
23       bool "Enable Scrollback Buffer in System RAM"
24       depends on VGA_CONSOLE
25       default n
26       help
27         The scrollback buffer of the standard VGA console is located in
28	 the VGA RAM.  The size of this RAM is fixed and is quite small.
29	 If you require a larger scrollback buffer, this can be placed in
30	 System RAM which is dynamically allocated during intialization.
31	 Placing the scrollback buffer in System RAM will slightly slow
32	 down the console.
33
34	 If you want this feature, say 'Y' here and enter the amount of
35	 RAM to allocate for this buffer.  If unsure, say 'N'.
36
37config VGACON_SOFT_SCROLLBACK_SIZE
38       int "Scrollback Buffer Size (in KB)"
39       depends on VGACON_SOFT_SCROLLBACK
40       default "64"
41       help
42         Enter the amount of System RAM to allocate for the scrollback
43	 buffer.  Each 64KB will give you approximately 16 80x25
44	 screenfuls of scrollback buffer
45
46config VIDEO_SELECT
47	bool "Video mode selection support"
48	depends on  X86 && VGA_CONSOLE
49	---help---
50	  This enables support for text mode selection on kernel startup. If
51	  you want to take advantage of some high-resolution text mode your
52	  card's BIOS offers, but the traditional Linux utilities like
53	  SVGATextMode don't, you can say Y here and set the mode using the
54	  "vga=" option from your boot loader (lilo or loadlin) or set
55	  "vga=ask" which brings up a video mode menu on kernel startup. (Try
56	  "man bootparam" or see the documentation of your boot loader about
57	  how to pass options to the kernel.)
58
59	  Read the file <file:Documentation/svga.txt> for more information
60	  about the Video mode selection support. If unsure, say N.
61
62config MDA_CONSOLE
63	depends on !M68K && !PARISC && ISA
64	tristate "MDA text console (dual-headed) (EXPERIMENTAL)"
65	---help---
66	  Say Y here if you have an old MDA or monochrome Hercules graphics
67	  adapter in your system acting as a second head ( = video card). You
68	  will then be able to use two monitors with your Linux system. Do not
69	  say Y here if your MDA card is the primary card in your system; the
70	  normal VGA driver will handle it.
71
72	  To compile this driver as a module, choose M here: the
73	  module will be called mdacon.
74
75	  If unsure, say N.
76
77config SGI_NEWPORT_CONSOLE
78        tristate "SGI Newport Console support"
79        depends on SGI_IP22
80        help
81          Say Y here if you want the console on the Newport aka XL graphics
82          card of your Indy.  Most people say Y here.
83
84#  bool 'IODC console' CONFIG_IODC_CONSOLE
85
86config PROM_CONSOLE
87	bool "PROM console"
88	depends on SPARC
89	help
90	  Say Y to build a console driver for Sun machines that uses the
91	  terminal emulation built into their console PROMS.
92
93config DUMMY_CONSOLE
94	bool
95	depends on PROM_CONSOLE!=y || VGA_CONSOLE!=y || SGI_NEWPORT_CONSOLE!=y

99        int "Initial number of console screen columns"
100        depends on PARISC && DUMMY_CONSOLE
101        default "160"
102        help
103          The default value is 160, which should fit a 1280x1024 monitor.
104          Select 80 if you use a 640x480 resolution by default.
105
106config DUMMY_CONSOLE_ROWS
107        int "Initial number of console screen rows"
108        depends on PARISC && DUMMY_CONSOLE
109        default "64"
110        help
111          The default value is 64, which should fit a 1280x1024 monitor.
112          Select 25 if you use a 640x480 resolution by default.
113
114config FRAMEBUFFER_CONSOLE
115	tristate "Framebuffer Console support"
116	depends on FB
117	select CRC32
118	help
119	  Low-level framebuffer-based console driver.
120
121config FRAMEBUFFER_CONSOLE_ROTATION
122       bool "Framebuffer Console Rotation"
123       depends on FRAMEBUFFER_CONSOLE
124       help
125         Enable display rotation for the framebuffer console.  This is done
126         in software and may be significantly slower than a normally oriented
127         display.  Note that the rotation is done at the console level only
128         such that other users of the framebuffer will remain normally
129         oriented.
130
131config STI_CONSOLE
132        tristate "STI text console"
133        depends on PARISC
134        default y
135        help
136          The STI console is the builtin display/keyboard on HP-PARISC
137          machines.  Say Y here to build support for it into your kernel.
138          The alternative is to use your primary serial port as a console.
139
140config FONTS
141	bool "Select compiled-in fonts"
142	depends on FRAMEBUFFER_CONSOLE || STI_CONSOLE
143	help
144	  Say Y here if you would like to use fonts other than the default
145	  your frame buffer console usually use.
146
147	  Note that the answer to this question won't directly affect the
148	  kernel: saying N will just cause the configurator to skip all
149	  the questions about foreign fonts.
150
151	  If unsure, say N (the default choices are safe).
152
153config FONT_8x8
154	bool "VGA 8x8 font" if FONTS
155	depends on FRAMEBUFFER_CONSOLE || STI_CONSOLE
156	default y if !SPARC && !FONTS
157	help
158	  This is the "high resolution" font for the VGA frame buffer (the one
159	  provided by the text console 80x50 (and higher) modes).
160
161	  Note that this is a poor quality font. The VGA 8x16 font is quite a
162	  lot more readable.
163
164	  Given the resolution provided by the frame buffer device, answer N
165	  here is safe.
166
167config FONT_8x16
168	bool "VGA 8x16 font" if FONTS
169	depends on FRAMEBUFFER_CONSOLE || SGI_NEWPORT_CONSOLE=y || STI_CONSOLE || USB_SISUSBVGA_CON
170	default y if !SPARC && !FONTS

172	  This is the "high resolution" font for the VGA frame buffer (the one
173	  provided by the VGA text console 80x25 mode.
174
175	  If unsure, say Y.
176
177config FONT_6x11
178	bool "Mac console 6x11 font (not supported by all drivers)" if FONTS
179	depends on FRAMEBUFFER_CONSOLE || STI_CONSOLE
180	default y if !SPARC && !FONTS && MAC
181	help
182	  Small console font with Macintosh-style high-half glyphs.  Some Mac
183	  framebuffer drivers don't support this one at all.
184
185config FONT_7x14
186	bool "console 7x14 font (not supported by all drivers)" if FONTS
187	depends on FRAMEBUFFER_CONSOLE
188	help
189	  Console font with characters just a bit smaller than the default.
190	  If the standard 8x16 font is a little too big for you, say Y.
191	  Otherwise, say N.
192
193config FONT_PEARL_8x8
194	bool "Pearl (old m68k) console 8x8 font" if FONTS
195	depends on FRAMEBUFFER_CONSOLE
196	default y if !SPARC && !FONTS && AMIGA

199	  glyphs.

203	depends on FRAMEBUFFER_CONSOLE
204	default y if !SPARC && !FONTS && ARM && ARCH_ACORN

206	  Small console font with PC-style control characters and high-half
207	  glyphs.

220	bool "Sparc console 12x22 font (not supported by all drivers)"
221	depends on FRAMEBUFFER_CONSOLE && (!SPARC && FONTS || SPARC)
222	help
223	  This is the high resolution console font for Sun machines with very
224	  big letters (like the letters used in the SPARC PROM). If the
225	  standard font is unreadable for you, say Y, otherwise say N.
226
227config FONT_10x18
228	bool "console 10x18 font (not supported by all drivers)" if FONTS
229	depends on FRAMEBUFFER_CONSOLE
230	help
231	  This is a high resolution console font for machines with very
232	  big letters. It fits between the sun 12x22 and the normal 8x16 font.
233	  If other fonts are too big or too small for you, say Y, otherwise say N.
