Re: Compile error saa7134 - compro videomate S350

Hi Hermann,

When I tried this I got the message "FATAL: saa7134-alsa is in use" (or something like that).

I wasn't sure what to look for here, there was a lot of info. being displayed.

I carried on with "modprobe -v saa7134 card=169" command.  I ran dmesg to see the status of the card.  It did get the card id 169 but the board decription came up as unknown instead of the name of the videomate S350.  Is this expected?

The modification of the GPIO address "Instead of 0x8000 used in Jan's patch, use 0xC000 for GPIO setup" I'm not sure what I changed was the correct value.  Looking at the code lines I found relate to the Remote that I had changed (saa7134-cards.c):


+	case SAA7134_BOARD_VIDEOMATE_S350:
+		dev->has_remote = SAA7134_REMOTE_GPIO;
+		saa_andorl(SAA7134_GPIO_GPMODE0 >> 2,   0x00008000, 0x00008000);
+		saa_andorl(SAA7134_GPIO_GPSTATUS0 >> 2, 0x00008000, 0x00008000);
+		break;

Which leads to the question where the GPIO address of 0x8000 is currently specified?


Thanks,
Dominic

unload the driver with "modprobe -vr saa7134-alsa saa7134-dvb".

You might have to close mixers using saa7134-alsa previously.
With "modinfo saa7134" you get available options.

With "modprobe -v saa7134 card=169" you can force that card then.

If we disable the T750 auto detection in saa7134-cards.c, both have to
force the correct card number.

Cheers,
Hermann
