dmesg 4.19-rc3
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
