The CUDA download pages on Nvidia's web site are rather confusing.<br>
<br>
There is the CUDA 6.5 Production Release [1] page for version 6.5.14
that has .run installers for Linux x86 32 and 64 bits.<br>
There is also a .run installer for Linux ARM 64, but for Linux ARM
32 it is only available as a .deb.<br>
The graphics driver bundled with version 6.5.14 is 340.29.<br>
<br>
There is also a CUDA 6.5 Production Release with Support for GeForce
GTX9xx GPUs [2] page for version 6.5.19 that has .run installers for
Linux x86 32 and 64 bits. The graphics driver bundled with version
6.5.19 is 343.19.<br>
The FAQ section of this page contains the following:<br>
Q: What's new?<br>
A: The 6.5.27 toolkit fixes the "nvlink error" when building any of
the cdp* sample.<br>
I think version 6.5.27 is available for Mac OSX only.<br>
<br>
Lastly, there is the
<meta http-equiv="content-type" content="text/html; charset=utf-8">
CUDA 7.0 Release Candidate [3] page (requires login) for version
7.0.18 that has a .run installer for Linux x86 64 bit only.<br>
There is a .deb installer for Linux POWER8 (ppc64el). The graphics
driver bundled with version 7.0.18 is 346.29.<br>
<br>
I am trying to decide whether to package 6.5.14 for x86 32 and 64
bits only, now, or hold out for the production release of 7.0.<br>
<br>
As far as Ubuntu goes, since nvidia-cuda-toolkit is in multiverse,
it is relatively easy to get a FeatureFreeze exception and that
could even be filed now if we decided to wait for 7.0.<br>
Ubuntu 15.04 will have driver version 346.35 (at least) and
hopefully some version of 340 as well (if I can convince Alberto -
346 drops support for many cards).<br>
<br>
Since dpkg 1.17.11, Debian now has versioned Provides [4]. This
could simplify the driver packaging in Ubuntu as we can get rid of
Provides: libcuda-5.0-1, libcuda-5.5-1, libcuda-6.0-1,
libcuda-6.5-1, libcuda-7.0-1, etc. We would probably only want to
change this in a LTS release, so nvidia-cuda-toolkit should continue
to Build-Depends on libcuda1 | libcuda-6.0-1 (or -6.5-1, or -7.0-1,
as applicable).<br>
