yes.
But I really think the problem is application-layer:
I do not see any errors in dmesg when running clinfo,
but when I run the application I'm developing, I see the following errors in
dmesg:
[31637.263268] amdgpu 0000:41:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT
domain=0x0014 address=0x00000000ff9f4000 flags=0x0000]
[31637.263379] amdgpu 0000:41:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT
domain=0x0014 address=0x00000000ff9e4000 flags=0x0000]
... and the application hangs
the interesting part here is: to make sure the driver does not "accidentally
work", I added a polaris device to the system.  The amdgpu recognised the
polaris, fiji and SI, but only the SI gives these faults.

do you know how I can figure out whether this is a kernel / midline /
application layer problem?
