+Understanding fbdev's cmap
+--------------------------
+
+These notes explain how X's dix layer uses fbdev's cmap structures.
+
+*. example of relevant structures in fbdev as used for a 3-bit grayscale cmap
+struct fb_var_screeninfo {
+ .bits_per_pixel = 8,
+ .grayscale = 1,
+ .red = { 4, 3, 0 },
+ .green = { 0, 0, 0 },
+ .blue = { 0, 0, 0 },
+}
+struct fb_fix_screeninfo {
+ .visual = FB_VISUAL_STATIC_PSEUDOCOLOR,
+}
+for (i = 0; i < 8; i++)
+ info->cmap.red[i] = (((2*i)+1)*(0xFFFF))/16;
+memcpy(info->cmap.green, info->cmap.red, sizeof(u16)*8);
+memcpy(info->cmap.blue, info->cmap.red, sizeof(u16)*8);
+
+*. X11 apps do something like the following when trying to use grayscale.
+for (i=0; i < 8; i++) {
+ char colorspec[64];
+ memset(colorspec,0,64);
+ sprintf(colorspec, "rgb:%x/%x/%x", i*36,i*36,i*36);
+ if (!XParseColor(outputDisplay, testColormap, colorspec, &wantedColor))
+ printf("Can't get color %s\n",colorspec);
+ XAllocColor(outputDisplay, testColormap, &wantedColor);
+ grays[i] = wantedColor;
+}
+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:
+
+xc-011010/programs/Xserver/dix/colormap.c:
+
+FindBestPixel(pentFirst, size, prgb, channel)
+
+dr = (long) pent->co.local.red - prgb->red;
+dg = (long) pent->co.local.green - prgb->green;
+db = (long) pent->co.local.blue - prgb->blue;
+sq = dr * dr;
+UnsignedToBigNum (sq, &sum);
+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.

+ Metronomefb
+ -----------
+Maintained by Jaya Kumar <jayakumar.lkml.gmail.com>
+Last revised: Nov 20, 2007
+
+Metronomefb is a driver for the Metronome display controller. The controller
+is from E-Ink Corporation. It is intended to be used to drive the E-Ink
+Vizplex display media. E-Ink hosts some details of this controller and the
+display media here http://www.e-ink.com/products/matrix/metronome.html .
+
+Metronome is interfaced to the host CPU through the AMLCD interface. The
+host CPU generates the control information and the image in a framebuffer
+which is then delivered to the AMLCD interface by a host specific method.
+Currently, that's implemented for the PXA's LCDC controller. The display and
+error status are each pulled through individual GPIOs.
+
+Metronomefb was written for the PXA255/gumstix/lyre combination and
+therefore currently has board set specific code in it. If other boards based on
+other architectures are available, then the host specific code can be separated
+and abstracted out.
+
+Metronomefb requires waveform information which is delivered via the AMLCD
+interface to the metronome controller. The waveform information is expected to
+be delivered from userspace via the firmware class interface. The waveform file
+can be compressed as long as your udev or hotplug script is aware of the need
+to uncompress it before delivering it. metronomefb will ask for waveform.wbf
+which would typically go into /lib/firmware/waveform.wbf depending on your
+udev/hotplug setup. I have only tested with a single waveform file which was
+originally labeled 23P01201_60_WT0107_MTC. I do not know what it stands for.
+Caution should be exercised when manipulating the waveform as there may be
+a possibility that it could have some permanent effects on the display media.
+I neither have access to nor know exactly what the waveform does in terms of
+the physical media.
+
+Metronomefb uses the deferred IO interface so that it can provide a memory
+mappable frame buffer. It has been tested with tinyx (Xfbdev). It is known
+to work at this time with xeyes, xclock, xloadimage, xpdf.
