| 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. |
