[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] Buffered IO for IO?
Has anyone experimented with adding Buffered IO support for "out" instructions? Currently, the buffered io pages is only used for mmio writes (and then only to vga space). It seems quite straight-forward to add. Two questions: (1) Does buffering actually have a measurable performance impact in it's current use? (2) Has anyone experimented with adding COM port ioreq buffering? If not I'll give it a rip and shout out what I find.
