This extra level makes an asymmetry with front ends (device/type/id) and are too long to make nice bus-ids under Linux, but the code isn't too horrible, and an OS which only wants to be a guest doesn't need to implement it. It allows backends to calculate the front-end path directly, which is a nice benefit. Also: subtype matching is tightened: they must match exactly. That way a future variant which requires a specific driver will not match current drivers.

The AIO support introduced in patch 9f0eff879d8913a824280cf67658a530c80e8424 still works -- The tap code maps a granted page twice, once in kernel and once in user. The kernel page is patched into the p2m table and pages added to the user vm_area are mapped to the appropriate underlying struct pages using the VM_FOREIGN hooks in get_user_pages(). Comparing block IO from dom0 to the existing block backend, and to the tap managing the same partition as the BE from user space with AIO, I get the following performance: Version 1.03 ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP xen0 2G 31198 95 56818 8 20967 2 28415 77 59595 4 264.9 0 xenU-blkbe2cpuGT 2G 31157 96 54026 10 25585 4 30664 90 64919 7 292.7 0 xenU-blktp2cpuGT 2G 32313 97 54217 8 20950 3 28117 87 65924 4 191.8 0 Signed-off-by: andrew.warfield@cl.cam.ac.uk
