I just included the plain Intel patches into the package. There was not yet too much interest in the patches anyway.

DPLL_A (DPLLA_CTRL-DPLL A Control Register) is documented here: Intel® 965 Express Chipset Family, Volume Three Section: Display Clock Control Registers The doc can be found here: http://intellinuxgraphics.org/documentation.html Cheers Thomas _______________________________________________ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
