Hi,
I recently got a Knights Corner Phi and have been setting it up. I set it up using the latest version of MPSS (3.8.1).
When trying to install the sampling driver, I get this message:
$ sudo ./micboot_install.sh
SEP configuration files have been successfully installed in the configuration directory.
Please run "service mpss restart" to start the SEP service.
itt successfully installed.
Please restart mpss service.
_amplxe_vtune_amplifier_xe_2017.1.0.486011 successfully installed.Enabling prebuild driver installation.
Cannot find a prebuilt driver for stack sampling collection enabling Intel MPSS 2.6.38.8+mpss3.8.1 in /opt/intel/vtune_amplifier_xe_2017.1.0.486011/mic_sepdk/prebuilt/vtsspp.
Suggestion: Make sure the MPSS version is specified correctly.
If this does not help, run <VTune_install_dir>/mic_sepdk/src/vtsspp/build_mic.sh to manually build the vtss driver and enable this type of collection on the coprocessor card.Enabling manual compilated driver installation.

unpack MPSS sources into /tmp/mic directory and then do

sudo service mpss restart
Complaining that there is no precompiled driver for that version of MPSS. I double checked the directory. Looks like the latest version that's bundled with VTune is 3.7.2:
$ ls /opt/intel/vtune_amplifier_xe_2017.1.0.486011/mic_sepdk/prebuilt/vtsspp

In the README.txt, it just says that the precompiled driver should work and gives no instructions for rebuilding them. I tried following Sebastian's comment in this posting https://software.intel.com/en-us/forums/intel-vtune-amplifier-xe/topic/499431 but wasn't successful.
Any ideas on how to get the correct driver?

Greetings!
Have you tried to rebuild the driver for your specific system?
The output message requests a rebuild of the vtss driver to enable stack sampling collection.
Try something along the lines of this:
sh /opt/intel/vtune_amplifier_xe/bin64/k1om/micboot_install.sh #unpack MPSS sources into /tmp/mic directory cp /mnt/nfs/System/mpss-src-3.8.1.tar /home/ cd /home/ tar xvf mpss-src-3.8.1.tar tar xvf mpss-3.8.1/src/linux-2.6.38+mpss3.8.1.tar.bz2 cd /opt/intel/vtune_amplifier_xe/mic_sepdk/src/vtsspp/ KDIR=/home/linux-2.6.38+mpss3.8.1 /opt/intel/vtune_amplifier_xe/mic_sepdk/src/vtsspp/build_mic.sh --build clean all sh /opt/intel/vtune_amplifier_xe/mic_sepdk/src/vtsspp/build_mic.sh --build
Thanks,
coast
