config DVB_MMAP
bool "Enable DVB memory-mapped API (EXPERIMENTAL)"
depends on DVB_CORE
depends on VIDEO_V4L2=y || VIDEO_V4L2=DVB_CORE
select VIDEOBUF2_VMALLOC
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
bool "DVB Network Support"
default (NET && INET)
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
bool "Enable DVB demux section packet loss log"
depends on DVB_CORE
help
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.
config DVB_ULE_DEBUG
bool "Enable DVB net ULE packet debug messages"
depends on DVB_CORE
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.
If you are unsure about this, say N here.
