I noticed some time ago that placing DP module to another core than the rest of the pipeline did not work on PTL any more. With other platforms it still worked and when turning CONFIG_USERSPACE=n PTL worked again too.
After some debugging I found out that there were some cache coherency issues in vregions that caused this. With these two fixes the sof-ptl-nocodec-dp-core-test.tplg topology works on PTL again too. I think we should add this or something similar to our CI. Maybe just edit nocodec topology a bit.
