0007 bool "Enable DVB memory-mapped API (EXPERIMENTAL)"

0010 select VIDEOBUF2_VMALLOC
0011 help
0012 This option enables DVB experimental memory-mapped API, which
0013 reduces the number of context switches to read DVB buffers, as
0014 the buffers can use mmap() syscalls.
0015
0016 Support for it is experimental. Use with care. If unsure,
0017 say N.

0019 config DVB_NET
0020 bool "DVB Network Support"
0021 default (NET && INET)
0022 depends on NET && INET && DVB_CORE
0023 help
0024 This option enables DVB Network Support which is a part of the DVB
0025 standard. It is used, for example, by automatic firmware updates used
0026 on Set-Top-Boxes. It can also be used to access the Internet via the
0027 DVB card, if the network provider supports it.
0028
0029 You may want to disable the network support on embedded devices. If
0030 unsure say Y.

0035 default 16
0036 range 1 255
0037 help
0038 Maximum number of DVB/ATSC adapters. Increasing this number
0039 increases the memory consumption of the DVB subsystem even
0040 if a much lower number of DVB/ATSC adapters is present.
0041 Only values in the range 4-32 are tested.
0042
0043 If you are unsure about this, use the default value 16
0044
0045 config DVB_DYNAMIC_MINORS
0046 bool "Dynamic DVB minor allocation"
0047 depends on DVB_CORE
0048 default y
0049 help
0050 If you say Y here, the DVB subsystem will use dynamic minor
0051 allocation for any device that uses the DVB major number.
0052 This means that you can have more than 4 of a single type
0053 of device (like demuxes and frontends) per adapter, but udev
0054 will be required to manage the device nodes.
0055
0056 If you are unsure about this, say N here.

0061 help
0062 Enable extra log messages meant to detect packet loss
0063 inside the Kernel.
0064
0065 Should not be enabled on normal cases, as logs can
0066 be very verbose.
0067
0068 If you are unsure about this, say N here.

0075 handling DVB network ULE packet loss inside the Kernel.
0076
0077 Should not be enabled on normal cases, as logs can
0078 be very verbose.
0079
0080 If you are unsure about this, say N here.
