failed to load igfxdcd into kernel

syk1 — Wed, 04 Aug 2021 06:57:24 GMT

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 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
