Hi,
I assume that you are referring to a proprietary licensed module that is
not built in to the kernel.
If this is the case, you wont be able to use any of the
EXPORT_SYMBOL_GPL functions, so that rules out /sys.
I would use /proc to export the data to userland.
Regards
Bob

Hello,
This is Benito from Brazil and I am work on a Android product.
I am facing a patent issue with one driver that is not GPL. It is out
of my control to release it GPL-like (I do not own the patent) but I
am authorized to modify it to meet a feature requirement. I need to
export a information to user space (any application can read) but
follow the common way (/sys FS) will lead to GPL violation (AFAIK use
kernel functions to export in /sys will make the driver GPL too, am I
wrong?).
Does anyone have idea on how to avoid patent and GPL violation while
still export the information?
Driver used to export this information through /dev/device_name,
however Google CTS enforced us to change /dev/device_name permission
avoiding applications to access it on behalf of normal user.
Thanks for any direction. My new feature needs this but I don't want
to fall in a legal issue with patent holder neither GPL.
Best regards,
