Re: [Intel-gfx] [RFC v1] Data port coherency control for UMDs.

We don’t have any timeline for this at the moment. NEO driver is quite fresh in open source and adoption will be handled in near future. Can we move on with review process and handle adoption in separate thread? Thanks, Bartosz -Original Message- From: Joonas Lahtinen

I think the adoption is not a problem here. If driver can query that patch is active on the specific setup, new capabilities will be always reported to the user. -Original Message- Quoting Dunajski, Bartosz (2018-03-26 12:46:13) > Here is pull request with patch usage: >
