docs: fb: convert docs to ReST and rename to *.rst

The conversion is actually:
  - add blank lines and identation in order to identify paragraphs;
  - fix tables markups;
  - add some lists markups;
  - mark literal blocks;
  - adjust title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

Also, removed the Maintained by, as requested by Geert.

 There's also named equivalents like gray1..x provided you have an rgb.txt.
 
 Somewhere in X's callchain, this results in a call to X code that handles the
 colormap. For example, Xfbdev hits the following:

+  BigNumAdd (&sum, &temp, &sum);
 
 co.local.red are entries that were brought in through FBIOGETCMAP which come
 directly from the info->cmap.red that was listed above. The prgb is the rgb
 that the app wants to match to. The above code is doing what looks like a least
 squares matching function. That's why the cmap entries can't be set to the left
 hand side boundaries of a color range.

+
+Introduction
+============
+
+This is a frame buffer device driver for 3dfx' Voodoo Graphics
+(aka voodoo 1, aka sst1) and Voodoo² (aka Voodoo 2, aka CVG) based
+video boards. It's highly experimental code, but is guaranteed to work
+on my computer, with my "Maxi Gamer 3D" and "Maxi Gamer 3d²" boards,
+and with me "between chair and keyboard". Some people tested other
+combinations and it seems that it works.
+The main page is located at <http://sstfb.sourceforge.net>, and if
+you want the latest version, check out the CVS, as the driver is a work
+in progress, I feel uncomfortable with releasing tarballs of something
+not completely working...Don't worry, it's still more than usable
+(I eat my own dog food)
+
+Please read the Bug section, and report any success or failure to me
+(Ghozlane Toumi <gtoumi@laposte.net>).
+BTW, If you have only one monitor , and you don't feel like playing
+with the vga passthrou cable, I can only suggest borrowing a screen
+somewhere...
+
+
+Installation
+============
+
+This driver (should) work on ix86, with "late" 2.2.x kernel (tested
+with x = 19) and "recent" 2.4.x kernel, as a module or compiled in.
+It has been included in mainstream kernel since the infamous 2.4.10.
+You can apply the patches found in `sstfb/kernel/*-2.{2|4}.x.patch`,
+and copy sstfb.c to linux/drivers/video/, or apply a single patch,
+`sstfb/patch-2.{2|4}.x-sstfb-yymmdd` to your linux source tree.
+
+Then configure your kernel as usual: choose "m" or "y" to 3Dfx Voodoo
+Graphics in section "console". Compile, install, have fun... and please
+drop me a report :)
+
+
+Module Usage
+============
+
+.. warning::
+
+       #. You should read completely this section before issuing any command.
+
+       #. If you have only one monitor to play with, once you insmod the
+	  module, the 3dfx takes control of the output, so you'll have to
+	  plug the monitor to the "normal" video board in order to issue
+	  the commands, or you can blindly use sst_dbg_vgapass
+	  in the tools directory (See Tools). The latest solution is pass the
+	  parameter vgapass=1 when insmodding the driver. (See Kernel/Modules
+	  Options)
+
+Module insertion
+----------------
+
+       #. insmod sstfb.o
+
+	  you should see some strange output from the board:
+	  a big blue square, a green and a red small squares and a vertical
+	  white rectangle. why? the function's name is self-explanatory:
+	  "sstfb_test()"...
+	  (if you don't have a second monitor, you'll have to plug your monitor
+	  directly to the 2D videocard to see what you're typing)
+
+       #. con2fb /dev/fbx /dev/ttyx
+
+	  bind a tty to the new frame buffer. if you already have a frame
+	  buffer driver, the voodoo fb will likely be /dev/fb1. if not,
+	  the device will be /dev/fb0. You can check this by doing a
+	  cat /proc/fb. You can find a copy of con2fb in tools/ directory.
+	  if you don't have another fb device, this step is superfluous,
+	  as the console subsystem automagicaly binds ttys to the fb.
+       #. switch to the virtual console you just mapped. "tadaaa" ...
+
+Module removal
+--------------
+
+       #. con2fb /dev/fbx /dev/ttyx
+
+	  bind the tty to the old frame buffer so the module can be removed.
+	  (how does it work with vgacon ? short answer : it doesn't work)
+
+       #. rmmod sstfb
+
+
+Kernel/Modules Options
+----------------------
+
+You can pass some options to the sstfb module, and via the kernel
+command line when the driver is compiled in:
+for module : insmod sstfb.o option1=value1 option2=value2 ...
+in kernel :  video=sstfb:option1,option2:value2,option3 ...
+
+sstfb supports the following options:
+
+=============== =============== ===============================================
+Module		Kernel		Description
+=============== =============== ===============================================
+vgapass=0	vganopass	Enable or disable VGA passthrou cable.
+vgapass=1	vgapass		When enabled, the monitor will get the signal
+				from the VGA board and not from the voodoo.
+
+				Default: nopass
+
+mem=x		mem:x		Force frame buffer memory in MiB
+				allowed values: 0, 1, 2, 4.
+
+				Default: 0 (= autodetect)
+
+inverse=1	inverse		Supposed to enable inverse console.
+				doesn't work yet...
+
+clipping=1	clipping	Enable or disable clipping.
+clipping=0	noclipping	With clipping enabled, all offscreen
+				reads and writes are discarded.
+
+				Default: enable clipping.
+
+gfxclk=x	gfxclk:x	Force graphic clock frequency (in MHz).
+				Be careful with this option, it may be
+				DANGEROUS.
+
+				Default: auto
+
+					- 50Mhz for Voodoo 1,
+					- 75MHz for Voodoo 2.
+

+dev=x		dev:x		Attach the driver to device number x.
+				0 is the first compatible board (in

+Tools
+=====
+
+These tools are mostly for debugging purposes, but you can
+find some of these interesting:
+
+- `con2fb`, maps a tty to a fbramebuffer::
+
+	con2fb /dev/fb1 /dev/tty5
+
+- `sst_dbg_vgapass`, changes vga passthrou. You have to recompile the
+  driver with SST_DEBUG and SST_DEBUG_IOCTL set to 1::
+
+	sst_dbg_vgapass /dev/fb1 1 (enables vga cable)
+	sst_dbg_vgapass /dev/fb1 0 (disables vga cable)
+
+- `glide_reset`, resets the voodoo using glide
+  use this after rmmoding sstfb, if the module refuses to
+  reinsert.
+
+Bugs
+====
+
+- DO NOT use glide while the sstfb module is in, you'll most likely
+  hang your computer.
+- If you see some artefacts (pixels not cleaning and stuff like that),
+  try turning off clipping (clipping=0), and/or using slowpci
+- the driver don't detect the 4Mb frame buffer voodoos, it seems that
+  the 2 last Mbs wrap around. looking into that .
+- The driver is 16 bpp only, 24/32 won't work.
+- The driver is not your_favorite_toy-safe. this includes SMP...
+
+	[Actually from inspection it seems to be safe - Alan]
+
+- When using XFree86 FBdev (X over fbdev) you may see strange color
+  patterns at the border of your windows (the pixels lose the lowest
+  byte -> basically the blue component and some of the green). I'm unable
+  to reproduce this with XFree86-3.3, but one of the testers has this
+  problem with XFree86-4. Apparently recent Xfree86-4.x solve this
+  problem.
+- I didn't really test changing the palette, so you may find some weird
+  things when playing with that.
+- Sometimes the driver will not recognise the DAC, and the
+  initialisation will fail. This is specifically true for
+  voodoo 2 boards, but it should be solved in recent versions. Please
+  contact me.
+- The 24/32 is not likely to work anytime soon, knowing that the
+  hardware does ... unusual things in 24/32 bpp.
+- When used with another video board, current limitations of the linux
+  console subsystem can cause some troubles, specifically, you should
+  disable software scrollback, as it can oops badly ...
+
+Todo
+====
+
+- Get rid of the previous paragraph.
+- Buy more coffee.
+- test/port to other arch.
+- try to add panning using tweeks with front and back buffer .
+- try to implement accel on voodoo2, this board can actually do a
+  lot in 2D even if it was sold as a 3D only board ...

+
+    viafb_active_dev:
+	This option is used to specify active devices.(CRT, DVI, CRT+LCD...)
+	DVI stands for DVI or HDMI, E.g., If you want to enable HDMI,
+	set viafb_active_dev=DVI. In SAMM case, the previous of
+	viafb_active_dev is primary device, and the following is
+	secondary device.
+
+	For example:
+
+	To enable one device, such as DVI only, we can use::
+
+	    modprobe viafb viafb_active_dev=DVI
+
+	To enable two devices, such as CRT+DVI::
+
+	    modprobe viafb viafb_active_dev=CRT+DVI;
+
+	For DuoView case, we can use::
+
+	    modprobe viafb viafb_active_dev=CRT+DVI
+
+	OR::
+
+	    modprobe viafb viafb_active_dev=DVI+CRT...
+
+	For SAMM case:
+
+	If CRT is primary and DVI is secondary, we should use::
+
+	    modprobe viafb viafb_active_dev=CRT+DVI viafb_SAMM_ON=1...
+
+	If DVI is primary and CRT is secondary, we should use::
+
+	    modprobe viafb viafb_active_dev=DVI+CRT viafb_SAMM_ON=1...
+
+    viafb_display_hardware_layout:
+	This option is used to specify display hardware layout for CX700 chip.
+
+	- 1 : LCD only
+	- 2 : DVI only
+	- 3 : LCD+DVI (default)
+	- 4 : LCD1+LCD2 (internal + internal)
+	- 16: LCD1+ExternalLCD2 (internal + external)
+
+    viafb_second_size:
+	This option is used to set second device memory size(MB) in SAMM case.
+	The minimal size is 16.
+
+    viafb_platform_epia_dvi:
+	This option is used to enable DVI on EPIA - M
+
+	- 0 : No DVI on EPIA - M (default)
+	- 1 : DVI on EPIA - M
+
+    viafb_bus_width:
+	When using 24 - Bit Bus Width Digital Interface,
+	this option should be set.
+
+	- 12: 12-Bit LVDS or 12-Bit TMDS (default)
+	- 24: 24-Bit LVDS or 24-Bit TMDS
+
+    viafb_device_lcd_dualedge:
+	When using Dual Edge Panel, this option should be set.
+
+	- 0 : No Dual Edge Panel (default)
+	- 1 : Dual Edge Panel
+
+    viafb_lcd_port:
+	This option is used to specify LCD output port,
+	available values are "DVP0" "DVP1" "DFP_HIGHLOW" "DFP_HIGH" "DFP_LOW".
+
+	for external LCD + external DVI on CX700(External LCD is on DVP0),
+	we should use::
+
+	    modprobe viafb viafb_lcd_port=DVP0...
+
+Notes:
+    1. CRT may not display properly for DuoView CRT & DVI display at
+       the "640x480" PAL mode with DVI overscan enabled.
+    2. SAMM stands for single adapter multi monitors. It is different from
+       multi-head since SAMM support multi monitor at driver layers, thus fbcon
+       layer doesn't even know about it; SAMM's second screen doesn't have a
+       device node file, thus a user mode application can't access it directly.
+       When SAMM is enabled, viafb_mode and viafb_mode1, viafb_bpp and
+       viafb_bpp1, viafb_refresh and viafb_refresh1 can be different.
+    3. When console is depending on viafbinfo1, dynamically change resolution
+       and bpp, need to call VIAFB specified ioctl interface VIAFB_SET_DEVICE
+       instead of calling common ioctl function FBIOPUT_VSCREENINFO since
+       viafb doesn't support multi-head well, or it will cause screen crush.
+
+
+Configure viafb with "fbset" tool
+---------------------------------
+
+    "fbset" is an inbox utility of Linux.
+
+    1. Inquire current viafb information, type::
+
+	   # fbset -i
+
+    2. Set various resolutions and viafb_refresh rates::
+
+	   # fbset <resolution-vertical_sync>
+
+       example::
+
+	   # fbset "1024x768-75"
+
+       or::
+
+	   # fbset -g 1024 768 1024 768 32
+
+       Check the file "/etc/fb.modes" to find display modes available.
+
+    3. Set the color depth::
+
+	   # fbset -depth <value>
+
+       example::
+
+	   # fbset -depth 16
+
+
+Configure viafb via /proc
+-------------------------
+    The following files exist in /proc/viafb
+
+    supported_output_devices
+	This read-only file contains a full ',' separated list containing all
+	output devices that could be available on your platform. It is likely
+	that not all of those have a connector on your hardware but it should
+	provide a good starting point to figure out which of those names match
+	a real connector.
+
+	Example::
+
+		# cat /proc/viafb/supported_output_devices
+
+    iga1/output_devices, iga2/output_devices
+	These two files are readable and writable. iga1 and iga2 are the two
+	independent units that produce the screen image. Those images can be
+	forwarded to one or more output devices. Reading those files is a way
+	to query which output devices are currently used by an iga.
+
+	Example::
+
+		# cat /proc/viafb/iga1/output_devices
+
+	If there are no output devices printed the output of this iga is lost.
+	This can happen for example if only one (the other) iga is used.
+	Writing to these files allows adjusting the output devices during
+	runtime. One can add new devices, remove existing ones or switch
+	between igas. Essentially you can write a ',' separated list of device
+	names (or a single one) in the same format as the output to those
+	files. You can add a '+' or '-' as a prefix allowing simple addition
+	and removal of devices. So a prefix '+' adds the devices from your list
+	to the already existing ones, '-' removes the listed devices from the
+	existing ones and if no prefix is given it replaces all existing ones
+	with the listed ones. If you remove devices they are expected to turn
+	off. If you add devices that are already part of the other iga they are
+	removed there and added to the new one.
+
+	Examples:
+
+	Add CRT as output device to iga1::
+
+		# echo +CRT > /proc/viafb/iga1/output_devices
+
+	Remove (turn off) DVP1 and LVDS1 as output devices of iga2::
+
+		# echo -DVP1,LVDS1 > /proc/viafb/iga2/output_devices
+
+	Replace all iga1 output devices by CRT::
+
+		# echo CRT > /proc/viafb/iga1/output_devices
+
+
+Bootup with viafb
+-----------------
+
+Add the following line to your grub.conf::
+
+    append = "video=viafb:viafb_mode=1024x768,viafb_bpp=32,viafb_refresh=85"

-        8, 16, 32 (default:32)
-
-    viafb_refresh1: (secondary display device)
-        60, 75, 85, 100, 120 (default:60)
-
-    viafb_active_dev:
-        This option is used to specify active devices.(CRT, DVI, CRT+LCD...)
-        DVI stands for DVI or HDMI, E.g., If you want to enable HDMI,
-        set viafb_active_dev=DVI. In SAMM case, the previous of
-        viafb_active_dev is primary device, and the following is
-        secondary device.
-
-        For example:
-        To enable one device, such as DVI only, we can use:
-            modprobe viafb viafb_active_dev=DVI
-        To enable two devices, such as CRT+DVI:
-            modprobe viafb viafb_active_dev=CRT+DVI;
-
-        For DuoView case, we can use:
-            modprobe viafb viafb_active_dev=CRT+DVI
-            OR
-            modprobe viafb viafb_active_dev=DVI+CRT...
-
-        For SAMM case:
-        If CRT is primary and DVI is secondary, we should use:
-            modprobe viafb viafb_active_dev=CRT+DVI viafb_SAMM_ON=1...
-        If DVI is primary and CRT is secondary, we should use:
-            modprobe viafb viafb_active_dev=DVI+CRT viafb_SAMM_ON=1...
-
-    viafb_display_hardware_layout:
-        This option is used to specify display hardware layout for CX700 chip.
-        1 : LCD only
-        2 : DVI only
-        3 : LCD+DVI (default)
-        4 : LCD1+LCD2 (internal + internal)
-        16: LCD1+ExternalLCD2 (internal + external)
-
-    viafb_second_size:
-        This option is used to set second device memory size(MB) in SAMM case.
-        The minimal size is 16.
-
-    viafb_platform_epia_dvi:
-        This option is used to enable DVI on EPIA - M
-        0 : No DVI on EPIA - M (default)
-        1 : DVI on EPIA - M
-
-    viafb_bus_width:
-        When using 24 - Bit Bus Width Digital Interface,
-        this option should be set.
-        12: 12-Bit LVDS or 12-Bit TMDS (default)
-        24: 24-Bit LVDS or 24-Bit TMDS
-
-    viafb_device_lcd_dualedge:
-        When using Dual Edge Panel, this option should be set.
-        0 : No Dual Edge Panel (default)
-        1 : Dual Edge Panel
-
-    viafb_lcd_port:
-        This option is used to specify LCD output port,
-        available values are "DVP0" "DVP1" "DFP_HIGHLOW" "DFP_HIGH" "DFP_LOW".
-        for external LCD + external DVI on CX700(External LCD is on DVP0),
-        we should use:
-            modprobe viafb viafb_lcd_port=DVP0...
-
-Notes:
-    1. CRT may not display properly for DuoView CRT & DVI display at
-       the "640x480" PAL mode with DVI overscan enabled.
-    2. SAMM stands for single adapter multi monitors. It is different from
-       multi-head since SAMM support multi monitor at driver layers, thus fbcon
-       layer doesn't even know about it; SAMM's second screen doesn't have a
-       device node file, thus a user mode application can't access it directly.
-       When SAMM is enabled, viafb_mode and viafb_mode1, viafb_bpp and
-       viafb_bpp1, viafb_refresh and viafb_refresh1 can be different.
-    3. When console is depending on viafbinfo1, dynamically change resolution
-       and bpp, need to call VIAFB specified ioctl interface VIAFB_SET_DEVICE
-       instead of calling common ioctl function FBIOPUT_VSCREENINFO since
-       viafb doesn't support multi-head well, or it will cause screen crush.
-
-
-[Configure viafb with "fbset" tool]
------------------------------------
-    "fbset" is an inbox utility of Linux.
-    1. Inquire current viafb information, type,
-           # fbset -i
-
-    2. Set various resolutions and viafb_refresh rates,
-           # fbset <resolution-vertical_sync>
-
-       example,
-           # fbset "1024x768-75"
-       or
-           # fbset -g 1024 768 1024 768 32
-       Check the file "/etc/fb.modes" to find display modes available.
-
-    3. Set the color depth,
-           # fbset -depth <value>
-
-       example,
-           # fbset -depth 16
-
-
-[Configure viafb via /proc]
----------------------------
-    The following files exist in /proc/viafb
-
-    supported_output_devices
-
-        This read-only file contains a full ',' separated list containing all
-        output devices that could be available on your platform. It is likely
-        that not all of those have a connector on your hardware but it should
-        provide a good starting point to figure out which of those names match
-        a real connector.
-        Example:
-        # cat /proc/viafb/supported_output_devices
-
-    iga1/output_devices
-    iga2/output_devices
-
-        These two files are readable and writable. iga1 and iga2 are the two
-        independent units that produce the screen image. Those images can be
-        forwarded to one or more output devices. Reading those files is a way
-        to query which output devices are currently used by an iga.
-        Example:
-        # cat /proc/viafb/iga1/output_devices
-        If there are no output devices printed the output of this iga is lost.
-        This can happen for example if only one (the other) iga is used.
-        Writing to these files allows adjusting the output devices during
-        runtime. One can add new devices, remove existing ones or switch
-        between igas. Essentially you can write a ',' separated list of device
-        names (or a single one) in the same format as the output to those
-        files. You can add a '+' or '-' as a prefix allowing simple addition
-        and removal of devices. So a prefix '+' adds the devices from your list
-        to the already existing ones, '-' removes the listed devices from the
-        existing ones and if no prefix is given it replaces all existing ones
-        with the listed ones. If you remove devices they are expected to turn
-        off. If you add devices that are already part of the other iga they are
-        removed there and added to the new one.
-        Examples:
-        Add CRT as output device to iga1
-        # echo +CRT > /proc/viafb/iga1/output_devices
-
-        Remove (turn off) DVP1 and LVDS1 as output devices of iga2
-        # echo -DVP1,LVDS1 > /proc/viafb/iga2/output_devices
-
-        Replace all iga1 output devices by CRT
-        # echo CRT > /proc/viafb/iga1/output_devices
-
-
-[Bootup with viafb]:
---------------------
-    Add the following line to your grub.conf:
-    append = "video=viafb:viafb_mode=1024x768,viafb_bpp=32,viafb_refresh=85"
