Hello quanxian,

Thank you for the tests and the feedback!

The Ubuntu 6.2 kernel builds and ships the 'idxd' and 'idxd_bus' kernel modules as well. However, they are shipped by the 'linux-modules-extra*' package.

Could you please make sure you have this package installed (e.g. linux-modules-extra-6.2.0-26-generic for your kernel version, or a more recent one) and let us know what are the test results with the 6.2 kernel? It would be great if the tests could be performed on both 22.04 and 23.04.

Can you also please elaborate on the config changes you had to do to perform the test? Were they only related to intel IOMMU did you also need other changes? For the intel IOMMU ones (CONFIG_INTEL_IOMMU_DEFAULT_ON and CONFIG_INTEL_IOMMU_SCALABLE_MODE_DEFAULT_ON), we have disabled them because they were causing boot issues in some platforms. Are they really necessary to be turned on in the kernel config or could they be kept as a boot parameter?
