Actually this is the same code as in the ilbm directory, except that here the
conversion from normal bitplanes to interleaved bitplanes didn't happen.

What is it?
-----------
Xdaniver is a fast, colour X11R6 server for the Amiga's custom chip set
under NetBSD 1.0 and NetBSD-current, supporting all the Amiga's display
depths from 1 to 4 (upto 16 colours) on ECS machines and 1 to 8 (upto 256
colours) on AGA machines (though, not all resolutions are available, see
General Information below).
Xdaniver is designed to be a drop-in replacement for the Xmono server provided
with the X11R6 binary distribution supplied by Bernd Ernesti available from
ftp.uni-regensburg.de or one of its mirrors.
Unlike previous colour X servers for the Amiga that emulate a chunky pixel
screen in fast RAM, use the standard frame buffer drivers provided with the
X11R6 source code to draw and then use a chunky to planar conversion routine
to write the results to the screen (all very slow), Xdaniver uses a heavily
modified mono frame buffer driver to draw directly using the Amiga's planar
format. The net result is much faster drawing and support for all the Amiga's
custom display depths but, as usual, the fewer planes used, the faster the
drawing operations of the X server. Even so, on my A1200 with a 33Mhz 68030,
I'm getting reasonable performance when using 8 bit planes in Dbl NTSC mode.
Installation
------------
You will need to have first obtained and installed the X11R6 binary
distribution available from ftp.uni-regensburg.de in
/pub/NetBSD-Amiga/contrib/X11 or one of its mirrors. Xdaniver has been
compiled to expect font and configuration files sitting under
/usr/local/X11R6, if your setup is different you will need to provide a
symbolic link from /usr/local/X11R6 to where your tree resides or supply
several command line flags to the server.
To get Xdaniver running as the default X server, copy the uncompressed binary
into /usr/local/X11R6/bin, remove the current X file from that directory
(which is a symbolic link to Xmono) and replace it with a link to Xdaniver:
gzip -d < X11R6.Xdaniver.1.01.tar.gz | tar xvf -
mv Xdaniver /usr/local/X11R6/bin
cd /usr/local/X11R6/bin
rm X
ln -s Xdaniver X
Note that on some setups, the devices /dev/kbd, /dev/mouse and /dev/view??
have been created to be accessable only by superuser; Xdaniver needs to open
these devices. To workaround this problem, log on as superuser and then
either make Xdaniver setuid root:
chown root Xdaniver
chmod 4755 Xdaniver
or give everyone access the devices:
chmod 666 /dev/kbd /dev/mouse /dev/view??
the latter option is a possible cause of a security hole if your machine is
ever used multi-user.
General Information
-------------------
The default resolution of the server is 700x430 and the default depth 4. AGA
users might what to increase the display depth by editing the startx script
and providing a -depth <depth> argument to Xdaniver on the xinit line of the
script. As always, the lower the depth, the faster the drawing and window
manipulation of the server.
The resolution can be altered similarly by suppling -width <width> and
-height <height> arguments to the server.
The NetBSD kernel selects actual screen modes by picking a mode who's
natural, non-overscanned size best-fits the requested resolution.
Unfortunately, for AGA users, the 1.0 kernel only has support for the
Dbl-NTSC AGA display mode and only this mode has support for depths greater
than 4. The NetBSD-current (work-in-progress) kernel also has support for
Dbl-PAL but still no support for the Super72 or other super-hires modes
(perhaps some kind, kernel-hacker could add support for them ?).
If you have a 2 button mouse (like me) you might want to try and use the 3
button mouse emulation. On other systems, it is usual for the left and right
buttons to be provided and emulate the middle button by pressing both
buttons together, however, the middle button is tends to be used more than
the right button so I have provided two options:
-emulateright (or -3), the two physical mouse buttons act as left and middle
and pressing them both together emulates the right button.
-emulatemiddle (or -2), the two physical mouse buttons act as left and right
and pressing them both together emulated the middle button.
When using screen depths of less than 6 (4 is the maximum for ECS machines)
the lack of possible colours on screen at once causes problems for many X
applications. Specifying -cc 2 as a command line argument to Xdaniver
causes the server to switch the default visual type from PsuedoColor to
StaticColor; to put it simply, the server prefills the colormap with a
selection of 16 colours (depth 4) and when an application asks for a
particular colour, its gets allocated one that is closest to one from the
selection of 16. This removes the 'WARNING: Cannot allocate colormap entry
for "XXX"' errors but at the expense of applications not being able to get
the precise colour they wanted. Also, some badly written X applications fail
altogether when presented with a StaticColor visual.
Bugs/Limitations
----------------
The limited choice of display resolutions for AGA/ECS machines is a real
pain - requires a kernel change to fix. Worse still, the kernel specifies
the maximum overscan resolution on the Dbl-NTSC to be 724x482 but selecting
anything more than 702x430 on my machine causes the screen either sheer
diagonally (as if the bytes per row calculation in Xdaniver or the kernel is
wrong) or completely loose sync (suggesting a custom chip register sync
calculation bug). As other, non-aga modes aren't affected when selection
overscan both problems seem to point to a kernel driver bug. Also, depths
greater than 4 for AGA users are only supported by the kernel in the Dbl-NTSC
mode (and Dbl-PAL with the current-NetBSD kernel).
I know of one bug so-far (there will be more), The PutImage request of an XY
format image expects the bitplane order to be the reverse of that specified
in the X protocol but since virtually all applications use the Z (chunky)
format, you are unlikely to come across this problem.
The PutImage request of Z format images is a little slow - when I have time
I'll try and add one of the fast assembly chunky-to-planar routines developed
for doom style games/demos. Unfortunately, the current crop all require a
picture size that is a multiple of 32 pixels and so cannot be used out-of-the-
box.
Some extra performance could easily be squeezed out of the terminal font
drawing code (used by xterm) - when I have time I'll add the code.
The Amiga's blitter and sprites are totally unused and will remain so
until/if someone else adds support to the kernel. The blitter would help
speed up screen scrolling and window manipulation and sprite support could
be used for the X pointer shape (if small enough) which would speed up all
drawing operations (no need to remove the software based pointer shape
first, draw, then replace the pointer shape).
I removed the X image extension (XIE) from the X server as it increased the
size of the binary by some 400k. I haven't come across any applications that
need it yet (I haven't been looking!) so if you need the extension for some
reason send me e-mail and I'll build a server with the extension included.
The 3 button mouse emulation is very simple - to emulate the 3rd button you
have to press both button precisely at the same moment - I've got quite good
at it now. When I have some spare time I'll add a timer so you will have a
few milli-seconds between one button being pressed and the next and it still
being registered as the emulated button.
AGA users don't forget to provide the -A flag to loadbsd to enable the one
AGA mode in the 1.0 kernel but only if you have a VGA, multisync or dual-scan
monitor, of course !
Xdaniver has been tested on:
A1200, 33Mhz 68030, 8Mb RAM and NetBSD 1.0 by myself.
A4000/40, 12Mb RAM and NetBSD 1.0 by Andreas Holzhammer.
A3000, 12Mb RAM and NetBSD 1.0 by Charlie Root, Stuart Park and others.
A3000, 25Mhz 68040, 18Mb RAM and NetBSD-current by Michael K. Sanders.
A2000, 8Mb RAM and NetBSD (version unknown) by Hubert Feyrer.
Release and Bug Fix History
---------------------------
1.0 - First release
1.01 Bugs fixed:
- Narrow (<32 pixels) Z format GetImage requests corrupted the stack
and could cause the server to core dump. (Xpaint caused this problem)
- Drawing dots (PolyPoint request) into a clipped window caused a
c pointer to go out of range, causing a core dump (xv showed this
problem).
New features:
- Simple 3 button mouse emulation using a 2 button mouse; specify
-emulate_middle (or -2) or -emulate_right (or -3) on the server's
command line and press both mouse buttons together emulate the 'missing'
button.
- Basic beep sound support added by sending bell characters to the
console.
- Source code released.

Credits
-------
Thanks to Bernd Ernesti for making the operating system server source code
available for others to use and Eduardo Horvath and Andy Heffernan, who (I
think) did the original Xmono server port.
Also, many thanks to the first brave users who tested Xdaniver for me on other
Amiga setups and found a few bugs in the process.

/** Optimized for drawing pixmaps into windows, especially when drawing into
** unobscured windows. Calls to the general-purpose region code were
** replaced with rectangle-to-rectangle clipping comparisions. This is
** possible, since the pixmap is a single rectangle. In an unobscured
** window, the destination clip is also a single rectangle, and region
** code can be avoided entirely. This is a big savings, since the region
** code uses XAlloc() and makes many function calls.
**
** In addition, if source is a pixmap, there is no need to call the
** expensive miHandleExposures() routine. Instead, we simply return NULL.
**
** Previously, drawing a pixmap into an unobscured window executed at least
** 8 XAlloc()'s, 30 function calls, and hundreds of lines of code.
**
** Now, the same operation requires no XAlloc()'s, no region function calls,
** and much less overhead. Nice for drawing lots of small pixmaps.

we should eventually special-case fixed-width fonts for ImageText.
this works for fonts with glyphs <= 32 bits wide.
the clipping calculations are done for worst-case fonts.
we make no assumptions about the heights, widths, or bearings
of the glyphs. if we knew that the glyphs are all the same height,
we could clip the tops and bottoms per clipping box, rather
than per character per clipping box. if we knew that the glyphs'
left and right bearings were wlle-behaved, we could clip a single
character at the start, output until the last unclipped
character, and then clip the last one. this is all straightforward
to determine based on max-bounds and min-bounds from the font.
there is some inefficiency introduced in the per-character
clipping to make what's going on clearer.
(it is possible, for example, for a font to be defined in which the
next-to-last character in a font would be clipped out, but the last
one wouldn't. the code below deals with this.)
Image text looks at the bits in the glyph and the fg and bg in the
GC. it paints a rectangle, as defined in the protocol dcoument,
and the paints the characters.
the register allocations for startmask and endmask may not
be the right thing. are there two other deserving candidates?
xoff, pdst, pglyph, and tmpSrc seem like the right things, though.

/* single-pixel lines on a color frame buffer
NON-SLOPED LINES
horizontal lines are always drawn left to right; we have to
move the endpoints right by one after they're swapped.
horizontal lines will be confined to a single band of a
region. the code finds that band (giving up if the lower
bound of the band is above the line we're drawing); then it
finds the first box in that band that contains part of the
line. we clip the line to subsequent boxes in that band.
vertical lines are always drawn top to bottom (y-increasing.)
this requires adding one to the y-coordinate of each endpoint
after swapping.
SLOPED LINES
when clipping a sloped line, we bring the second point inside
the clipping box, rather than one beyond it, and then add 1 to
the length of the line before drawing it. this lets us use
the same box for finding the outcodes for both endpoints. since
the equation for clipping the second endpoint to an edge gives us
1 beyond the edge, we then have to move the point towards the
first point by one step on the major axis.
eventually, there will be a diagram here to explain what's going
on. the method uses Cohen-Sutherland outcodes to determine
outsideness, and a method similar to Pike's layers for doing the
actual clipping.

/*
this works for fonts with glyphs <= 32 bits wide.
the clipping calculations are done for worst-case fonts.
we make no assumptions about the heights, widths, or bearings
of the glyphs. if we knew that the glyphs are all the same height,
we could clip the tops and bottoms per clipping box, rather
than per character per clipping box. if we knew that the glyphs'
left and right bearings were wlle-behaved, we could clip a single
character at the start, output until the last unclipped
character, and then clip the last one. this is all straightforward
to determine based on max-bounds and min-bounds from the font.
there is some inefficiency introduced in the per-character
clipping to make what's going on clearer.
(it is possible, for example, for a font to be defined in which the
next-to-last character in a font would be clipped out, but the last
one wouldn't. the code below deals with this.)

this works for fonts with glyphs <= PPW bits wide.
This should be called only with a terminal-emulator font;
this means that the FIXED_METRICS flag is set, and that
glyphbounds == charbounds.
in theory, this goes faster; even if it doesn't, it reduces the
flicker caused by writing a string over itself with image text (since
the background gets repainted per character instead of per string.)
this seems to be important for some converted X10 applications.
Image text looks at the bits in the glyph and the fg and bg in the

* \section GLAPIIntroduction Introduction
*
* The Mesa GL API module is responsible for dispatching all the
* gl*() functions. All GL functions are dispatched by jumping through
* the current dispatch table (basically a struct full of function
* pointers.)
*
* A per-thread current dispatch table and per-thread current context
* pointer are managed by this module too.
*
* This module is intended to be non-Mesa-specific so it can be used
* with the X/DRI libGL also.
