Hi,
I recently ran the below commands on my Ubunutu 20.04 machine with an 11th Gen Intel(R) Core(TM) i9-11950H and a discrete Nvidia RTX A3000.
sudo apt update
sudo apt upgrade
The following modules were installed and upgraded.
Install: linux-oem-5.14-headers-5.14.0-1057:amd64 (5.14.0-1057.64, automatic), linux-headers-5.14.0-1057-oem:amd64 (5.14.0-1057.64, automatic), linux-image-5.14.0-1057-oem:amd64 (5.14.0-1057.64, automatic), docker-buildx-plugin:amd64 (0.10.2-1~ubuntu.20.04~focal, automatic), linux-modules-5.14.0-1057-oem:amd64 (5.14.0-1057.64, automatic)

I then rebooted the system and found out that initramfs was not installed and had to install that. Once it finally booted without errors, I was trying to run some SYCL based software and found out that "sycl-ls" command was not detecting the GPU.
$ sycl-ls
[opencl:acc:0] Intel(R) FPGA Emulation Platform for OpenCL(TM), Intel(R) FPGA Emulation Device 1.2 [2022.15.12.0.01_081451]

I then ran the "cliinfo" command and found that openCL was detecting the GPU.
$ cliinfo

...
Can I get some help to understand why SYCL is not detecting a GPU anymore after the upgrade. My inital guess is that it could be the possible kernal upgrade that occurred in the upgrade.
Cheers

Hi,
“Thank you for your inquiry. We can only offer direct support for Intel hardware platforms that the Intel® oneAPI product supports. Intel provides instructions on how to compile oneAPI code for both CPU and a wide range of GPU accelerators.

Hi,
If you need any additional information, please post a new question as this thread will no longer be monitored by Intel.
