7 bool "Enable DVB memory-mapped API (EXPERIMENTAL)"
9 depends on VIDEO_V4L2=y || VIDEO_V4L2=DVB_CORE
10 select VIDEOBUF2_VMALLOC
12 This option enables DVB experimental memory-mapped API, which
13 reduces the number of context switches to read DVB buffers, as
14 the buffers can use mmap() syscalls.
16 Support for it is experimental. Use with care. If unsure,
20 bool "DVB Network Support"
22 depends on NET && INET && DVB_CORE
24 This option enables DVB Network Support which is a part of the DVB
25 standard. It is used, for example, by automatic firmware updates used
26 on Set-Top-Boxes. It can also be used to access the Internet via the
27 DVB card, if the network provider supports it.
29 You may want to disable the network support on embedded devices. If
32 config DVB_MAX_ADAPTERS
33 int "maximum number of DVB/ATSC adapters"
38 Maximum number of DVB/ATSC adapters. Increasing this number
39 increases the memory consumption of the DVB subsystem even
40 if a much lower number of DVB/ATSC adapters is present.
41 Only values in the range 4-32 are tested.
43 If you are unsure about this, use the default value 16
45 config DVB_DYNAMIC_MINORS
46 bool "Dynamic DVB minor allocation"
50 If you say Y here, the DVB subsystem will use dynamic minor
51 allocation for any device that uses the DVB major number.
52 This means that you can have more than 4 of a single type
53 of device (like demuxes and frontends) per adapter, but udev
54 will be required to manage the device nodes.
56 If you are unsure about this, say N here.
