Howto configure the Linux kernel / drivers / media / dvb / cinergyT2



  • Option: DVB_CINERGYT2
    • Kernel Versions: 2.6.15.6 ...
    • (on/off/module) Terratec CinergyT2/qanu USB2 DVB-T receiver
    • depends on DVB_CORE && USB
      Support for "TerraTec CinergyT2" USB2.0 Highspeed DVB Receivers
      Say Y if you own such a device and want to use it.



  • Option: DVB_CINERGYT2_TUNING
    • Kernel Versions: 2.6.15.6 ...
    • (on/off) sophisticated fine-tuning for CinergyT2 cards
    • depends on DVB_CINERGYT2
      Here you can fine-tune some parameters of the CinergyT2 driver.
      Normally you don't need to touch this, but in exotic setups you may fine-tune your setup and adjust e.g. DMA buffer sizes for a particular application.



  • Option: DVB_CINERGYT2_STREAM_URB_COUNT
    • Kernel Versions: 2.6.15.6 ...

"Number of queued USB Request Blocks for Highspeed Stream Transfers"

    • depends on DVB_CINERGYT2_TUNING default "32"
      USB Request Blocks for Highspeed Stream transfers are scheduled in a queue for the Host Controller.
      Usually the default value is a safe choice.
      You may increase this number if you are using this device in a Server Environment with many high-traffic USB Highspeed devices sharing the same USB bus.



  • Option: DVB_CINERGYT2_STREAM_BUF_SIZE
    • Kernel Versions: 2.6.15.6 ...

"Size of URB Stream Buffers for Highspeed Transfers"

    • depends on DVB_CINERGYT2_TUNING default "512"
      Should be a multiple of native buffer size of 512 bytes. Default value is a safe choice.
      You may increase this number if you are using this device in a Server Environment with many high-traffic USB Highspeed devices sharing the same USB bus.



  • Option: DVB_CINERGYT2_QUERY_INTERVAL
    • Kernel Versions: 2.6.15.6 ...

"Status update interval [milliseconds]"

    • depends on DVB_CINERGYT2_TUNING default "250"
      This is the interval for status readouts from the demodulator. You may try lower values if you need more responsive signal quality measurements.
      Please keep in mind that these updates cause traffic on the tuner control bus and thus may or may not affect receiption sensitivity.
      The default value should be a safe choice for common applications.



  • Option: DVB_CINERGYT2_ENABLE_RC_INPUT_DEVICE
    • Kernel Versions: 2.6.15.6 ...
    • (on/off) Register the onboard IR Remote Control Receiver as Input Device
    • depends on DVB_CINERGYT2_TUNING default "yes"
      Enable this option if you want to use the onboard Infrared Remote Control Receiver as Linux-Input device.
      Right now only the keycode table for the default Remote Control delivered with the device is supported, please see the driver source code to find out how to add support for other controls.



  • Option: DVB_CINERGYT2_RC_QUERY_INTERVAL
    • Kernel Versions: 2.6.15.6 ...

"Infrared Remote Controller update interval [milliseconds]"

    • depends on DVB_CINERGYT2_TUNING && DVB_CINERGYT2_ENABLE_RC_INPUT_DEVICE default "50"
      If you have a very fast-repeating remote control you can try lower values, for normal consumer receivers the default value should be a safe choice.
