David/Stefano, can you take a look, and ack if you are happy with this?
I could build it on ARM and a backported version on 3.10 have seen quite
a lot of testing recently.

Please use a more specific name. bounce is too generic. I know
tracepoints are grouped by systems, but its easier for tools to just

Correct. The double buffering code is being run in lib/swiotlb.c not the
xen-swiotlb.c. Hence the question of why not move the tracing in there.
I've put the trace to both locations before swiotlb_tbl_map_single is
called, so the same tracer will

device's DMA range. If swiotlb_force == 1, you should really change the kernel
parameters. Otherwise, the buffer is not contiguous in mfn space.
