[linux-dvb] Re: [RFC] Frontend API, DiSEqC 2.0 additions

[Holger Waechtler <holger@convergence.de>]

Hi all,

I modified the DiSEqC ioctl's to FE_DISEQC_SEND_MASTER_CMD and 
FE_DISEQC_RECV_SLAVE_REPLY so that we can handle two-way DiSEqC 2.0. 
Anyway, I don't have a device here where I can implement and test this...

You can get the complete header file from the NEWSTRUCT branch, here the 
DiSEqC 2.0 related snippets:

------------------------------------------------------------------

struct dvb_diseqc_master_cmd {
         uint8_t msg [6];        /*  { framing, address, command, data 
[3] } */
         uint8_t msg_len;        /*  valid values are 3...6  */
};


struct dvb_diseqc_slave_reply {
         uint8_t msg [4];        /*  { framing, data [3] } */
         uint8_t msg_len;        /*  valid values are 0...4, 0 means no 
msg  */
         int timeout;            /*  return from ioctl after timeout ms 
with */
};                              /*  errorcode when no message was 
received  */


#define FE_DISEQC_SEND_MASTER_CMD  _IOW('o', 63, struct 
dvb_diseqc_master_cmd)
#define FE_DISEQC_RECV_SLAVE_REPLY _IOW('o', 64, struct 
dvb_diseqc_slave_reply)
