[linux-dvb] Re: AverTV DVB-T not working under Kernel 2.6.6

[Martin Kenny]

Hi, Further to my last message (about 2.6.6-rc1 vs 2.6.6), I've narrowed the problem down to a new ioctl case handler (FE_GET_TUNE_SETTINGS) in sp887x.c. By commenting that out, everything starts working again. Is this a problem with the implementation of FE_GET_TUNE_SETTINGS, or of whatever code uses that ioctl? Cheers, Marty. --- sp887x.c.old        2004-06-01 22:50:06.334919371 +0930 +++ sp887x.c    2004-06-01 22:41:05.061451829 +0930 @@ -631,18 +631,20 @@                 }                 /* enable TS output and interface pins */                 sp887x_writereg(fe, 0xc18, 0x00d);                 break; +#if 0         case FE_GET_TUNE_SETTINGS:         {                 struct dvb_frontend_tune_settings* fesettings = (struct dvb_frontend_tune_settings*) arg;                 fesettings->min_delay_ms = 50;                 fesettings->step_size = 0;                 fesettings->max_drift = 0;                 return 0;         } +#endif         default:                 return -EOPNOTSUPP;          }; Mike Harris wrote: Hi, I've just bought a new AverTV DVB-T card.
