bt848x driver choose its operating parameter by following strategy:
card-type
parameter automatically.
card-type
parameter is specified in configuration file,
driver will use it.
card-type
parameter is not specified, driver will use “0”
(generic or unknown).
card-type
.
Each parameters can be “overwritten” at latter steps. So values that are described in configuration file will be most priotized.
Driver configuration file locates at /platform/`uname
-m`/kernel/drv/bt848x.conf. Configuration file can hold many
operating parameters. See driver.conf(4)
manual page for
detailed notation and concept. Actual parameters are decribed in
other section. See config.
If you changed configuration file, its change will _NOT_ be reflected immediately.
[Solaris 9 or later] Issue update_drv bt848x command to update driver configuration.
[Solaris 8] “modunload -i 0” command will force to unload unused drivers. Once unloaded, next open of device file will updates driver configuration.
If you have more than 1 card in a machine, you should specify parameters with comma-separated, except 'video-mux' and 'audio-mux' (parameter detail is described later). For example:
card-type=11,13; # type of card #1 is 11, and #2 is 13 video-inputs=3,4; # number of inputs equipted card #1 is 3, #2 is 4 video-mux0=1,2,3; # card #1 video multiplexer config video-mux1=2,0,1,3; # card #2 video multiplexer config
card-type
If capture card has PCI subsystem IDs and known to driver, default
value of card-type
is assumed by them. If else, “0”
(=unknown or generic card) is assumed by default.
This parameter affects all other parameters. But, this parameter is
evaluated ahead of them. So you can overwrite other parameters.

More precise tuning is performed in this order, but more response time is needed. '0' is sufficient for almost case.
