Bug#807579: [CUDA 7.5] patch version 7, driver is a potential blocker

[lumin]

Hi everyone,

This is the v7 patch. Current status:
there's nearly no difference between v6 and v7 patch.

[amd64] several weeks ago it builds. list-missing is checked.
        but don't know if ppc64el stuff breaks anything.

[ppc64el] if libcuda.so.1 from nvidia-driver* can be provided for 
          ppc64el, it should be able to pass the build.
          list-missing not checked.


For ppc64el dpkg-shlibdeps requires a `libcuda.so.1` for ppc64el, which means
the nvidia driver for ppc64el should be uploaded before CUDA, in a normal way.

dpkg-shlibdeps: error: couldn't find library libcuda.so.1 needed by debian/libcuinj64-7.5/usr/lib/powerpc64le-linux-gnu/libcuinj64.so.7.5.18 (ELF format: 'elf64-powerpcle'; RPATH: '')

So should CUDA 7.5 be blocked by nvidia driver for ppc64el ?

NVIDIA provided ppc64el drivers in the CUDA7.5 deb ball,
but NVIDIA doesn't provide it directly on its driver web page.
Besides, the driver version from CUDA7.5 ball is detached with
others...

  nvidia-driver/unstable 352.79-2 amd64

but nvidia-driver for ppc64el in the CUDA ball is 352.39.

How should we continue ?
Or is there a way telling {dh_,dpkg-}shlibdeps to ignore libcuda.so.1 ?

Thanks in advance.
