I am tring to install igfxdcd to debug dpcpp file according to this link

(https://software.intel.com/content/www/us/en/develop/documentation/get-started-with-debugging-dpcpp-linux/top.html)

igfxdcd-1.8.0-Linux.deb is installed successfully, I can see compiled igfxdcd.ko under /lib/modules/5.4.0-77-generic/updates/dkms/

modinfo igfxdcd also shows something.

But modprobe igfxdcd failed with root user

modprobe: ERROR: could not insert 'igfxdcd': Operation not permitted

 

Kernel I am running is also same as kernel installed

 

root@station:/home/# uname -a
Linux 5.4.0-77-generic #86-Ubuntu SMP Thu Jun 17 02:35:03 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

 

Do you have any idea on this and can provide some help?

My environment is ubuntu 20.04 on i7-10700K with a gen9 GPU

the oneAPI version is BaseKit_p_2021.3.0.3219

Thanks

Hi,

 

Thanks for reaching out to us.

 

Could you please let us know whether the latest GPU drivers are installed on your system? If yes, please provide the version of GPU drivers.

 

If not, you can install the latest GPU drivers from the following link below.

Hi Shivani,

 

Yes, I have follow the instructions and install the latest driver on ubuntu.

I thought the reason should be my GPU is not included in official released igfxdcd 1.8.0

in the source code of igfxdcd, there is only 1 devide registered for commet lake (0x9BCA) in /usr/src/igfxdcd-1.8.0/skus.h

My device 0x9bc5 is not included.

output of lspci is:

00:02.0 VGA compatible controller: Intel Corporation Device 9bc5 (rev 05)

 

Thanks,

Yuankun
