I suspect the real definition should be

"After this interface runs the device and other views of
memory includes all dirty cache lines on the processor. On
processors with cache coherent bus interfaces this may well
be a no operation

Footnote: AGP tends to have its own coherency and caching setup
so the AGP drivers use their own interfaces to avoid needless
overhead"
