Just a short question: Am I correct in noticing that the tool
currently only supports standalone GPUs and not the APUs, e.g. I have
VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Kabini [Radeon HD 8210]
as part of an AMD E1-2100 APU and the tool tells me:
nils at teela ~ $ umr -c
ERROR: Device 0x9834 not found in UMR device table
ASIC not found (instance=0, did=ffffffff)
I also don't see any reference to kabini in the tool's code, so unless
I'm doing something wrong, this might be expected, right?
