Hey antti, list,
whilst trying to help some Asus U3100+ users with the recent patches I
ran into an issue. For some strange reason his chip_id was 0xff. I'd
hope this is somehow supplied by the firmware. I think I had the exact
same issue until I used Antti's latest firmware for the AF9035.
Having said that, I know antti currently hosts the latest firmware for
the af9035, but there seem to be several out in the wild and people
googling for the firmware tend to find the really old one.
I'm pretty certain that Afa-tech, IT-tech etc won't allow the firmware
to live in the kernel, or simply refuse to answer shuch a plead? They
could be persuaded by the maintainer to at least have it live in
http://git.kernel.org/?p=linux/kernel/git/firmware/linux-firmware.git or
if that fails, have it pulled by Documentation/dvb/get_dvb_firmware?
(Btw, why is it get_dvb_firmware? I didn't find a generic script or
other devices that did the same).
I'll update the af9035 wikipage to link to antti's firmware for now.
Oliver

Yes, it is the firmware. AF9035/AF9033 firmware is aware of used tuner
and there is some logic inside firmware for each tuner, like calculating
signal strength and handling of tuner I2C bus. Same applies for
AF9015/AF9013 too where this has caused some notable problems - I have
asked few times if someone could reverse and fix that fw to behave better.

Feel free to try. I tried it ages back in 2009 but failed.
Someone should make some study of these firmwares and list what are
differences, supported tuners etc. That was discussed at the time af9035
was merged to the Kernel... As rule of thumb test first newest firmware.
Currently there is no 100% automated script to dump those firmwares from
the binary. AF9035 driver seems to contain multiple firmwares. Maybe
making script that finds and dumps all firmwares found from binary could
be handy.

Good!

Ok, then I'll await said test results with latest firmware.

Maybe as an alternative, also have the firmwares linked/uploaded to
http://linuxtv.org/downloads/firmware/ ?

and done.
those older firmwares for the af9035 are only there for archive
purpouse? Or are their known cases where older firmware is needed? At
this moment, it seems that the oldest one (11.5.9) brakes things.

Mainly for archive. But there could be cases, like some annoying
behavior, people are willing to test other versions too. That happens
for example af9015 firmware where the oldest one didn't support firmware
based remote at all.
When I lastly dumped out few firmwares I found out there was actually 2
firmwares that reports same versions, but are still different:
md5sum dvb-usb-af9035-02.fw_12.5.13.0_6.8.13.0*
817887199bc15dc820b808317d06a2bd dvb-usb-af9035-02.fw_12.5.13.0_6.8.13.0
f357c0534aba8ced25a5b1a37e19a287
dvb-usb-af9035-02.fw_12.5.13.0_6.8.13.0_2nd
I didn't looked reason more carefully, but I expect there is some chunk
which contains different register initialization stuff. Maybe different
hw layout or diversity or like that.
So there is room for research, but not person to do that heh.

Antti
