What about AMDGPU_GEM_DOMAIN_CPU? I mean, that's unlikely to actually be
used here, but if it were, exporting and importing the resulting BO
should work fine?
Instead of white-listing the domains which can be shared, it might be
better to black-list those which can't, i.e. GDS/GWS/OA.
Well first of all GDS can be shared between applications.
Then adding a BO to the tracking doesn't add much overhead (only 8 bytes
and only if it was the last allocated).
So I don't really see a reason why we should do this?
Christian.
