help
|
|
This option enables DVB experimental memory-mapped API, which
|
|
reduces the number of context switches to read DVB buffers, as
|
|
the buffers can use mmap() syscalls.
|
|
|
|
Support for it is experimental. Use with care. If unsure,
|
|
say N.

config DVB_NET

depends on NET && INET && DVB_CORE
|
|
help
|
|
This option enables DVB Network Support which is a part of the DVB
|
|
standard. It is used, for example, by automatic firmware updates used
|
|
on Set-Top-Boxes. It can also be used to access the Internet via the
|
|
DVB card, if the network provider supports it.
|
|
|
|
You may want to disable the network support on embedded devices. If
|
|
unsure say Y.

config DVB_MAX_ADAPTERS

|
int "maximum number of DVB/ATSC adapters"
|

depends on DVB_CORE
|
|
default 16
|
|
range 1 255
|
|
help
|
|
Maximum number of DVB/ATSC adapters. Increasing this number
|
|
increases the memory consumption of the DVB subsystem even
|
|
if a much lower number of DVB/ATSC adapters is present.
|
|
Only values in the range 4-32 are tested.
|
|
|
|
If you are unsure about this, use the default value 16
|
|
|
|
config DVB_DYNAMIC_MINORS
|
|
bool "Dynamic DVB minor allocation"
|
|
depends on DVB_CORE
|
|
default y
|
|
help
|
|
If you say Y here, the DVB subsystem will use dynamic minor
|
|
allocation for any device that uses the DVB major number.
|
|
This means that you can have more than 4 of a single type
|
|
of device (like demuxes and frontends) per adapter, but udev
|
|
will be required to manage the device nodes.
|
|
|
|
If you are unsure about this, say N here.

config DVB_DEMUX_SECTION_LOSS_LOG

Enable extra log messages meant to detect packet loss
|
|
inside the Kernel.
|
|
|
|
Should not be enabled on normal cases, as logs can
|
|
be very verbose.

If you are unsure about this, say N here.

help

Enable extra log messages meant to detect problems while
|
|
handling DVB network ULE packet loss inside the Kernel.
|
|
|
|
Should not be enabled on normal cases, as logs can
|
|
be very verbose.
