Xeon w5 does not enabled DSA SVM feature

[YongInLee]

Hello

I cannot enable SVM feature of DSA.

[ 5.863737] idxd 0000:e7:01.0: enabling device (0144 -> 0146)
[ 5.863765] idxd 0000:e7:01.0: Unable to turn on user SVA feature.
[ 5.884903] idxd 0000:e7:01.0: Intel(R) Accelerator Device (v100)

This kernel options are enabled for SVM.

# cat config-6.7.9-svm1 | grep INTEL_IOMMU
CONFIG_INTEL_IOMMU=y
CONFIG_INTEL_IOMMU_SVM=y
CONFIG_INTEL_IOMMU_DEFAULT_ON=y
CONFIG_INTEL_IOMMU_FLOPPY_WA=y
CONFIG_INTEL_IOMMU_SCALABLE_MODE_DEFAULT_ON=y
CONFIG_INTEL_IOMMU_PERF_EVENTS=y

# cat config-6.7.9-svm1 | grep IDXD
CONFIG_INTEL_IDXD_BUS=m
CONFIG_INTEL_IDXD=m
# CONFIG_INTEL_IDXD_COMPAT is not set
CONFIG_INTEL_IDXD_SVM=y
CONFIG_INTEL_IDXD_PERFMON=y

 

I used 6.7.9 mainline kernel on Ubuntu 22.04.3.

My Xeon system is assembled Xeon W5-3435X and Supermicro X13SWA-TF board.
