Hello,

Any patch yet for above issue? It seems to have made it into 2.6.26.

I use saa7134 with everything, including the tuner modules, compiled
as a module. My card is detected as a flyvideo2000. The default tuner
for that card (#37) allows me to tune into TV but not to FM Radio. I
can access both functions (TV and FM Radio) if I override with
tuner=69, which is what I usually do. That override does not work on
2.6.26.

Any suggestions?

Thanks,

Modify saa7134_board_init2 so that the manual tuner type setting isn't
ignored. The first thing it does is to overwrite the current value
(set earlier from module parameter) with the static values... even
before trying to autodetect it.

In saa7134-core.c saa7134_initdev:
 dev->tuner_type   = saa7134_boards[dev->board].tuner_type;
+dev->tuner_addr   = saa7134_boards[dev->board].tuner_addr;

In saa7134-cards.c saa7134_board_init2:
-dev->tuner_type   = saa7134_boards[dev->board].tuner_type;
-dev->tuner_addr   = saa7134_boards[dev->board].tuner_addr;

I think that will fix it.

this restores tuner behavior on the saa7134 driver.

I can't test XCeive tuners, which load different firmware dynamically.
Mauro was on them.

Please send the patch to Mauro and/or provide your signed-off-by.

This must go to the stable team ASAP as well.

[PATCH] saa7134: Copy tuner data earlier in init to avoid overwriting manual tuner type

[Simon Arlott]

When saa7134_board_init2 runs, it immediately overwrites the current value
(set earlier from module parameter) of tuner_type with the static values,
and then does autodetection. This patch moves the tuner_addr copy to earlier
in saa7134_initdev and removes the tuner_type copy from saa7134_board_init2.

Autodetection could still potentially change to the wrong tuner type, but it
is now possible to override the default type for the card again.

My card's tuner is configured with autodetection from eeprom, so I don't 
need to manually set the tuner. I've checked that the autodetection still 
works for my card.

And, indeed, it fixed it. I hope the patch will make it into the main-line.
