10config DVB_CINERGYT2_TUNING
11 bool "sophisticated fine-tuning for CinergyT2 cards"
12 depends on DVB_CINERGYT2
13 help
14 Here you can fine-tune some parameters of the CinergyT2 driver.
15
16 Normally you don't need to touch this, but in exotic setups you
17 may fine-tune your setup and adjust e.g. DMA buffer sizes for
18 a particular application.

24 default "32"
25 help
26 USB Request Blocks for Highspeed Stream transfers are scheduled in
27 a queue for the Host Controller.
28
29 Usually the default value is a safe choice.
30
31 You may increase this number if you are using this device in a
32 Server Environment with many high-traffic USB Highspeed devices
33 sharing the same USB bus.

41 Should be a multiple of native buffer size of 512 bytes.
42 Default value is a safe choice.

44 You may increase this number if you are using this device in a
45 Server Environment with many high-traffic USB Highspeed devices

49config DVB_CINERGYT2_QUERY_INTERVAL
50 int "Status update interval [milliseconds]"
51 depends on DVB_CINERGYT2_TUNING
52 default "250"
53 help
54 This is the interval for status readouts from the demodulator.
55 You may try lower values if you need more responsive signal quality
56 measurements.
57
58 Please keep in mind that these updates cause traffic on the tuner
59 control bus and thus may or may not affect reception sensitivity.
60
61 The default value should be a safe choice for common applications.

70 Control Receiver as Linux-Input device.

82 If you have a very fast-repeating remote control you can try lower
83 values, for normal consumer receivers the default value should be
84 a safe choice.
