Future of the Linux-Driver

[softnhard]

Take a look to http://blog.mohammadzadeh.info/index.php/step-by-step-guide-to for a complete guide on how to install.

The "official" 2.6.38 kernel's driver has been appeared on the Downloads page,

However... it is not in-line with real 2.6.38 driver's structure; it still uses legacy "linux/drivers/media/IR" instead of "linux/drivers/media/rc", etc, etc.

I don't suppose there are any release notes with it, or available?

It looks like there are few updated files to it, but can't tell what's been done - apart from it actually compiles now without all the hacking we've had to do.

[stevellion]

I can confirm it compiles, installs and works fine though!

[smv1210]

Yes it does compile, however, if you are going to use vdr-sasc-ng with it, an additional patch is still needed:

Could someone please point me to this new driver for 2.6.38.

I can still only see the rar file for 2.6.35 on the downloads page.

Cheers.

Thanks a lot.

I'm still getting same errors as when I compiled with Andys patch.

It looks like this new rar is just a re-packaging or Andys work and not a proper solution

[stevellion]

What errors are you getting? I just compiled it straight away, with no problems.

Did you follow all the README instructions properly?

With these latest drivers, you shouldn't need any patches.
