Do you envision this being used for stuff like libalsa, libusb, a v4l2 lib, etc.? I always felt that this kind of libraries are sort of "part of the kernel" in the sense that programs really do need them to interface with the kernel. (*) If we had a privelidged libv4l2 library like that then things like format conversion and video encoding / decoding could be done in user space and we could provide a more "high level" standard interface for user programs. This is the sort of thing that libalsa already does with audio software mixing (for instance) with the advantage that we need to keep the interface between libalsa and the kernel across kernel versions. Of course, the interface exported by these libraries would now be the official kernel interface. -- Paulo Marques - www.grupopie.com Pointy-Haired Boss: I don't see anything that could stand in our way. Dilbert: Sanity? Reality? The laws of physics? (*) Yeah, one can write programs that don't use the libraries, but that is just asking for trouble... - 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/
