GPU device of i9-9900k can't be identified by clinfo on a ubuntu 16.04

[juliusshufan]

Hi,

I am using i9-9900k on a ubuntu 16.04.

After install the latest release of opencl runtime, and add the corresponding user to video group, the GEN9 GPU device still can't be detected, only CPU device can be detected.
May I know the 9900k is supported by the latest opencl runtime?

Thanks.

Yes, this GPU is supported. Which kernel version are you using? For CFL platform i915.alpha_support=1 kernel parameter is required under Ubuntu 16.04.4 with default kernel 4.13.

If this doesn't help, please run
strace -s 255 -f -o log.txt clinfo
and attach the log here.

To check support for any device, you can follow these steps:

1. Go to Ark and find your Device ID. In this case it’s 0x3E98.
2. Find the corresponding device ID label in GMM. In this case it’s ICFL_GT2_S8_S2_DT_DEVICE_F0_ID.
3. Check if this device ID label is enumerated in the supported device list

@AdamCetnerowski Thanks, I am working with @airMeng on your steps.

Here is the log. Unfortunately I still got non-gou device

@AdamCetnerowski Following the step, but GPU device still not enabled.
Could you kindly check the log from myside, and you may ignore the one from @airMeng as that one is not valid. Thanks.

Looks like there are missing entries in /dev/dri.

Please check this:

lspci | grep VGA

if iGPU is missing ("VGA compatible controller: Intel Corporation ...") then probably it was disabled by BIOS (you need to change BIOS settings and enable Integrated GPU).

If it still doesn't work, please provide this information:

dmesg | grep -E 'drm|i915'

@alalek Thanks for the prompt response.

Thank you for update!

dmesg output seems very short.

Looks like, i915 driver is not bound to the PCI device.
Usually this means that used version of Linux kernel doesn't know anything about the device (or binding is blocked via configuration/kernel boot parameters - boot parameters is fine, blacklisting is not enabled).

Expected lines:

    Capabilities: [300 v1] #13
    Kernel driver in use: i915
    Kernel modules: i915

4.15.0-29-generic

This kernel version is not fresh: https://ubuntu.pkgs.org/16.04/ubuntu-updates-main-amd64/linux-image-4.15.0-29-generic_4.15.0-29.31~16.04.1_amd64.deb.html
Changelog date is about 2018-07-17.

Compare these sources (search for '0x3e98' - your pci device id)

• Ubuntu's 4.15.0-29 (missing 3e98)
• fresh Ubuntu's 4.15.0-54 (available 3e98)

So, try to upgrade kernel (it is useful to have backup if something goes wrong)

apt-get update
apt-get upgrade      # upgrades all packages on system (it is useful to have backup of root fs)
# or apt-get install --upgrade \
#        linux-image-generic-hwe-16.04-edge  \
#        ...other_kernel_packages_like_headers_extra_modules_etc...
# ... reboot
# ... check again starting from 'lspci -s 00:02.0 -nnn -vvv'

@alalek Your solution work indeed, appreciate for your prompt help. I close this issue accordingly.

[laygond]

@juliusshufan hello, I see you are running ubuntu16.04 with that CPU. What motherboard are you using for that configuration? Thanks in advance :)
