13	select APERTURE_HELPERS if (DRM || FB || VFIO_PCI_CORE)
14	default y
15	help
16	  Saying Y here will allow you to use Linux in text mode through a
17	  display that complies with the generic VGA standard. Virtually
18	  everyone wants that.
19
20	  The program SVGATextMode can be used to utilize SVGA video cards to
21	  their full potential in text mode. Download it from
22	  <ftp://ibiblio.org/pub/Linux/utils/console/>.
23
24	  Say Y.

26config MDA_CONSOLE
27	depends on !M68K && !PARISC && ISA
28	tristate "MDA text console (dual-headed)"
29	help
30	  Say Y here if you have an old MDA or monochrome Hercules graphics
31	  adapter in your system acting as a second head ( = video card). You
32	  will then be able to use two monitors with your Linux system. Do not
33	  say Y here if your MDA card is the primary card in your system; the
34	  normal VGA driver will handle it.
35
36	  To compile this driver as a module, choose M here: the
37	  module will be called mdacon.
38
39	  If unsure, say N.

41config SGI_NEWPORT_CONSOLE
42	tristate "SGI Newport Console support"
43	depends on SGI_IP22 && HAS_IOMEM
44	select FONT_SUPPORT
45	help
46	  Say Y here if you want the console on the Newport aka XL graphics
47	  card of your Indy.  Most people say Y here.

54	int "Initial number of console screen columns"
55	depends on DUMMY_CONSOLE && !ARM
56	default 160 if PARISC
57	default 80
58	help
59	  On PA-RISC, the default value is 160, which should fit a 1280x1024
60	  monitor.
61	  Select 80 if you use a 640x480 resolution by default.
62
63config DUMMY_CONSOLE_ROWS
64	int "Initial number of console screen rows"
65	depends on DUMMY_CONSOLE && !ARM
66	default 64 if PARISC
67	default 25
68	help
69	  On PA-RISC, the default value is 64, which should fit a 1280x1024
70	  monitor.
71	  Select 25 if you use a 640x480 resolution by default.

80	  Low-level framebuffer-based console driver.

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