It should be rethought and rewritten. Repent! % % Requires the devices /dev/cgfour0, /dev/cgfour0_ovl, and /dev/cgfour0_ove % (which can all be major 39 minor 0, or whatever), and the following patch % to the NeWS 1.1 server sources (but X11/NeWS doesn't need to be patched!), % in order to take advantage of a cg4 under NeWS 1.1 (Otherwise it falls back % to using exclusive-or). % % Put the flag -DCG4_ENABLE_HACK into COPTS in the top level server Makefile. % Make the following patch to the file SUN/src/server/dev/sunw/pixrectint.c: % In function cg4_make: % Replace the block starting with the following comment: % /* set up pixrect initial state */ % { % #ifdef CG4_ENABLE_HACK % int initplanes, initfb = CG4_INITFB; % extern char *sun_fb_name; % char *index(); % int len = strlen (sun_fb_name); % % /* Special file names get overlay and enable planes */ % if (index(sun_fb_name, '_') != NULL) { % if (sun_fb_name[len-1] == 'l') /* cgfour0_ovl */ % initfb = 0; /* overlay plane */ % else if (sun_fb_name[len-1] == 'e') /* cgfour0_ove */ % initfb = 1; /* enable plane */ % else initfb = 2; /* color plane */ % } % % initplanes = % PIX_GROUP(fbdesc[initfb].group) | % fbdesc[initfb].allplanes; % #else !CG4_ENABLE_HACK % int initplanes = % PIX_GROUP(fbdesc[CG4_INITFB].group) | % fbdesc[CG4_INITFB].allplanes; % #endif !CG4_ENABLE_HACK % % (void) cg4_putattributes(pr, &initplanes); % } % % Damn damn damn!
