Hey,
I wanted to try the newly-added support for Raven Ridge in amdkfd, but initialization fails at: "kfd: Failed to resume IOMMU for device 1002:15dd" on AMD Ryzen 5 2500U (Lenovo E485) with 4.19-rc3. IOMMU itself seems to initialize fine (As I understand, I can ignore the "AMD-Vi: Unable to write to IOMMU perf counter." msg). Full log is attached.
Best regards Marvin
