This bug is awaiting verification that the linux-intel- iotg/5.15.0-1037.42 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy' to 'verification- done-jammy'. If the problem still exists, change the tag 'verification- needed-jammy' to 'verification-failed-jammy'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

The current 5.15 iotg kernel missing the patches to boost GPU frequency. This affects ADL platform. Attached patches fix the issue. ./matrix_multiply Running on device: Intel(R) Graphics [0x46a6] Success!
