Should I have done so? Fact is I waste 38 kB of Ram with two completely senseless DST modules being compiled and loaded into RAM although I do not need them at all!
1) with a 2.6.17+ kernel they aren't loaded (check modinfo dvb-bt8xx) so you can simply remove / not install those modules 2) you should look at bttv and its deps because it even takes 175kb [1] compared to cx878-core which takes 13 kb currently (will stay below 20kb even in a final version i think)

How do I have to imply that tree? Just copy the modules in the kernel tree? Or how? Thanks!
Copy the tree into v4l-dvb and adjust the makefiles ...

Christoph [1] notes about the module sizes (fully stripped, current v4l-dvb) dvb-bt8xx.ko (12812) + bt878.ko (8356) = 21168 bytes dst_ca.ko (11064) + dst.ko (21060) = 32124 bytes size of bttv (needed by bt878.ko) and its dependencies in media/video/* bttv: 108328 video-buf: 15300 v4l2-common: 17768 tveeprom: 12752 videodev: 20628 gives 174776 bytes ... _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
