I don't think the prefer dm_ is right here. The dm above stands for
DeviceMatch. I would call this variable just rkisp1.

Could you wrap this line ? We try to keep lines under the 80 columns
limit when possible, with a hard limit at 120 when wrapping isn't
possible at all.
cerr << "Failed to populate media device "
<< dm_rkisp1->deviceNode() << endl;
Other than that the patch looks good to me. It duplicates code from the
IPU3 test, and it would be nice to share the code instead, but we plan
to work on pipeline-specific tests in the near future, so we'll handle
that refactoring.
Could you please send a v2 with those small issues fixed ?
