After this interface runs, > the entire cpu cache is flushed. 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" - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
