Hello, I am trying to install vtune drivers on my computer. I get the follwoing error. Can you please help me.

You may need to build pax driver for your kernel.

Hello,

What is your Linux distribution version? You may try to build drivers from sources. You can find instructions in./sepdk/src/README.txt. Actually you need to run ./sepdk/src/build-driver and than run ./sepdk/src/insmod-sep3 to install it.

Regards,
Kirill

[Dharma]

I did build the driver before loading:
I am using RHEL 5.2

Try steps: (under vtune_amplifier_xe_2011/sepdk/src)
1. ./rmmod-sep3
2. rmmod pax
3. ./build_driver
4. ./insmod-sep3
5. ./boot-script -- install

Regards, Peter

[Dharma]

I did all the steps you mentioned. For ./build-driver, i used the default options.

I get the same error message that i mentioned in the first post.

[Peter_W_Intel]

Did you work on Virtual Box?

Have you seen sep and pax driver before running insmod-sep3?
lsmod | grep sep
lsmod | grep pax

[Dharma]

I do not work on a virtual box. I remote login to my server, and su - to login as root. I doub if that is an issue. I did vtune install long time back, using version 9.1, i uninstalled that version now. I was to use the software then. that was about two years ago.

i get no output when i run lsmod commands.

[Dharma]

does this information help,
I cannot seem to make much out of it but seems relavent.

[root@dirac ~]# dmesg | grep pax

[Dharma]

I could finally load the drivers. The problem was with the gcc version. For some reason, gcc4.1 was missing from my server, i installed a later version. I read in some fourom that if the gcc version used for bulding kernal doesnot match that used for bulding the driver, i get the erro i mentioned.

Thanks

[Michael_L_6]

Hi there, I have a similar problem.

I try to install vtune, and it exit with this error:

I double check the kernel, and it is using the same GCC version as well.  Is there a version of GCC that is needed?

I am using this: gcc version 4.3.4 [gcc-4_3-branch revision 152973] (SUSE Linux)

[Robert_L_Intel1]

Hello Michael - You do appear to have the correct version of gcc.  At least the 4.3.4 version is what I find in package descriptions for SUSE 11, SP1.  Have you attempted to build the driver manually as described higher up in the thread, according to the readme?  See Kirill's response.  If so, what was the result?  Can you post the build output?

[Peter_W_Intel]

Before building pax driver, you need to check if Linux* kernel source matches running operation system version, then you will get expected driver name.

My case:

# uname -r
2.6.32-71.el6.x86_64

# pwd
/opt/intel/vtune_amplifier_xe_2015/sepdk/src/pax

# ls pax-*.ko

pax-x32_64-2.6.32-71.el6.x86_64smp.ko

[David_A_Intel1]

The build-driver script will inform you if the sources don't match.  And which version of GCC is not so important, it's the kernel version, as Peter pointed out.

Based on the post from @Michael L., I would say he doesn't have a driver that matches.  E.g., The prompt says "linux-2.6.32.12-0.7", while the driver file says "./pax/pax-x32_64-2.6.32.59-0.7-default-fslsmp.ko".  (Assuming the prompt is correct.)

Of course, all of this should have been done during installation, assuming a recent version.  What version of the VTune Amplifier are you using, 2013 or 2015?  If 2013, which update?  Did you install it on this system as root, using sudo, or just as a user?  What happened during install?  Did you see any messages about failing to build or load the driver?

Anyway, at this point, cd in the pax directory, <vtuneinstall>/sepdk/src/pax, and attempt to build the driver (build-driver script).  Once successfully built, cd up to sepdk/src and execute the build-driver script in that directory.  If that builds everything successfully, execute the insmod-sep3 script.  (these instructions assume a current version, as well)

[Michael_L_6]

To Peter Wang:

this is what I get:

/opt/intel/vtune_amplifier_xe_2015/sepdk/src/pax # uname -r
2.6.32.59-0.7-default-fsl
/opt/intel/vtune_amplifier_xe_2015/sepdk/src/pax # pwd
/opt/intel/vtune_amplifier_xe_2015/sepdk/src/pax
/opt/intel/vtune_amplifier_xe_2015/sepdk/src/pax # ls pax-*.ko
pax-x32_64-2.6.32.59-0.7-default-fslsmp.ko

Look like pax is using the same version as my kernel, both at 2.6.32.59-0.7

To Bob L

I did compile it manually - but it fail as well for pax load

I didn't capture log, so I will try again and show logs.

[David_A_Intel1]

Is this a virtualized environment?  Can you execute the command 'amplxe-feedback -create-bug-report report.zip' and either send it to me via private message or open an issue at Intel® Premier Support, where you will have an account if you registered your software, purchased or eval?

Also, notice that while the pax driver did build, it did not copy it to the location that it would be loaded from:

cp: `pax-x32_64-2.6.32.59-0.7-default-fslsmp.ko' and `/opt/intel/vtune_amplifier_xe_2015/sepdk/src/pax/pax-x32_64-2.6.32.59-0.7-default-fslsmp.ko' are the same file

Try renaming the existing file, rebuilding the pax driver, and then loading it via insmod-sep3.

BTW, what does the output of 'file pax-x32_64-2.6.32.59-0.7-default-fslsmp.ko' look like?
