The instructions given in the readme file unfortunately make some assumptions. (The directions in the next release are a bit clearer I believe.)

Anyway, did you install the kernel-headers and kernel-devel packages from the Centos release? And are you using the version of gcc and glibc that came in the src directory with the MPSS?

[Hemant_A_]

Dear Frances Roth , Thank  you for your reply.

Centos version 6.4,

Kernel 3.11.5-1.el6.elrepo.x86_64

GCC version 4.4.7 20120313 ( Red Har 4.4.7-3)

bitutils 2.20.51.0.2-5.36.el6.x86_64

yes we installed the kernel headers  and kernel devel  packages.

[Frances_R_Intel]

I will check with the developers to be sure, but, after digging around some more, I think the answer is you cannot use the 3.11 kernel unless you modify the code for the mic kmod. In the meantime, there may be other users out there who have done this and perhaps they will chime in with suggestions.

[Frances_R_Intel]

After asking around, I couldn't find anyone here who has tried anything beyond 3.5. And I don't have any timeframe for when it will be supported in an MPSS release. Sorry

[GRoes]

I too would like to use kernel 3.11 (.6-1) from elrepo, on Scientific Linux, with mpss 3.1. I want to use this kernel because my Xeon E3-1225 v3 will then have proper video support. And yes, my Phi works fine using 2.6.32-358.23.2.el6.x86_64 on that little workstation :-)

My error is this:

Hopefully newer versions of the mpss stack wil have support for newer kernels. Or better, mic.ko will be assimilated into the normal kernel tree.

I was able to make the mic module compile on Linux kernel version up to Linux-3.11.

It's tested and working on Linux-3.11.6 and you can find it here:
https://github.com/xdsopl/mpss-modules

Would be nice if someone from Intel could review the patches and maybe help as i am not familiar with the code and could have missed something.

It would be also nice if you guys could test the code and give feedback. Patches are also welcome :)

Ahmet

[Frances_R_Intel]

Thank you for your effort, Ahmet. I'll let you know if I hear any feedback.

[GRoes]

I tested Ahmet's mpss kernel module and it works on 3.11.6 AND on 3.12.0. Nice! Thanks Ahmet.

Hi, I am trying to install mpss 3.1 on ubuntu 13 with kernel 3.10. when I make install mic module i get a message:

"make -C /lib/modules/3.11.0-15-generic/build M=/home/user1/temp/MIC/mpss-modules-master modules_install \

When I try to modprobe mic, i get FATAL ERROR mic not found and it succeeds with insmod. and later when i try to depmod, i get an error message

"ERROR: fstatat(3, mic.ko): Too many levels of symbolic links"

[TaylorIoTKidd]

Roshan,

MPSS doesn't support Ubuntu, though there are successful ports for earlier versions of MPSS.

Additionally, there is a newer version of MPSS coming out in late Q1, so I suggest you delaying any personal porting efforts until then.

Regards

PS I notice that you posted similar questions under other threads. I put a similar answer (well, actually identical) there.
