We don't mix scanout and LLC, so we've never felt concerned to enable this flush. [It's definitely not gen12+!] I would not enable this bit without good cause and verification it doesn't cost anything for normal render paths. Still we need to record this bit. For example, I might suggest it is coupled into the flush-display path directly. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
