Status of RTL283xU support?

Status of RTL283xU support?

[Maik Zumstrull]

Hi Antti,

it seems I've found myself with an rtl2832u-based DVB-T USB stick. The
latest news on that seems to be that you were working on cleaning up
the code of the Realtek-provided GPL driver, with the goal of
eventually getting it into mainline.

Would you mind giving a short status update?

Is there a working out-of-tree version somewhere I could build? I've
tried the linuxtv.org build script against your tree, but it fails
with git errors; possibly due to the recent outage of git.kernel.org.


Thanks,

Maik

Shortly, It is error No time, -ENOTIME.

I have two LinuxTV related projects that are higher priority.
* AF9013 rewrite to optimize I2C IO
* Anysee smartcard reader

I think my rtl28xx tree should be rebased to latest code. MFE support at 
least have made such changes it will not compile top of latest tree.

And the tree I have does support only very limited set of RTL2831U 
devices. It was Maxim Levitsky working for RTL2832U but he have given up.

Antti

Isn't it always. :-) I won't be holding my breath for 3.3, then.

Thanks for the info and your efforts.

I hope development will be revived by someone eventually. When looking
around, it seemed to me that this chipset is becoming more and more
common with low-end devices.

I've ordered a different stick that is supposed to be fully supported
already, so I should be fine until then.

Ah, does the Realtek branch have support for DAB(+) and FM?  In
Windows the chip can do DAB+ and FM as well as DVB-T.  The problem I
think is that the DAB and FM demodulation has to be done in software
so the driver would only tune the chip and provide the digitised
baseband signal.  If this could be done then throwing the data stream
into something like OpenDAB's demodulator should work.

FYI, someone has contacted me off-list to point out that the newest(?)
Realtek tree for these devices is available online:

Gave it a spin, built out of tree against Debian's Linux 3.0 binaries.
Basically works, you can get a signal, but has crashed my system a few
times. Removed it again. YMMV.
