| config DVB_MMAP |
| bool "Enable DVB memory-mapped API (EXPERIMENTAL)" |
| depends on DVB_CORE |
| depends on VIDEO_DEV=y || VIDEO_DEV=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. |
