This is a multipart MIME message. --===_0_Sat_Mar_22_16:21:48_PST_1997 Content-Type: text/plain; charset=us-ascii This is patch is against the /sys/pci/brooktree848.c found in 3.0-current. Create a tuner device: mknod tuner0 c 79 16 This means that there can only be a maximum of 15 capture devices . Access your tuner ioctl thru your tuner device handle and anything which controls the video capture process thru the video device handle. The functions which have been added are: tuner_open tuner_close tuner_ioctl Which are access thru the minor device. What this means is that applications if they want to access the tuner, they should open the device "/dev/tuner0", then set channels, mute audio, etc... Tuner hackers now have a nice isolated home in the driver 8) Please let me know if you like the changes or not .
