Hello Antti,
As we known that AF9013 has the hardware pid filter capability.
How to implement the hardware pid filter, which the demodulator has this
capability?
For usb, i find
struct dvb_usb_adapter_fe_properties {
int (*pid_filter_ctrl) (struct dvb_usb_adapter *, int);
int (*pid_filter) (struct dvb_usb_adapter *, int, u16, int);
.......
It can implement the hardware filter if the demodulator has.
But on the other interface, i do not find similar solution.
For example, we have a hardware of AF9013 and CX23885 pcie chip and want to use
the hardware pid filter in AF9013.
i find some codes to hook the dvb.demux to do that pid filtering.
I think it is demod property, but the current "dvb_frontend_ops" has no
definition for this.
It is better that adding a function pointer of pid filtering in
"dvb_frontend_ops" to do in general way.
What is your idea?
It is not supported currently - only DVB USB supports it.
In order to PID filter for the demodulator you will need to change DVB
fronted code. Copy some PID -filtering stuff from the DVB USB to the
frondend handling.
regards
Antti
