Hi,

At least, this needs a comment explaining what the function does, and maybe wrap it in a helper like virtio_input_bitmap_copy or virtio_bitmap_or.Can do that, sure.
Well, the function where this is in already cares about the bitmap copy only. Can add a comment though.

You are doing leXXX everywhere, that's VERSION_1 dependency. virtio_cread will do byteswaps differently without VERSION_1. Just don't go there.Changed that for v2, for the config space structs. They have normal u32 in there now. virtio_cread() wants it this way.
I liked the __le32 in the config space structs more though, so I've waded through the virtio_config.h header file. To me it looks like we need separate virtio_cread() versions for non-transitional drivers, which do __le32 -> u32 translation instead of __virtio32 -> u32 translation, so I can have __le32 types in the config space structs. Or I could use vdev->config->get() directly instead of virtio_cread, but I'll loose sparse checking that way. Hmm. Recommendations? Better ideas? cheers, Gerd
