Re: [Xen-devel] Multiple-page mem_event ring buffer?

Could I safely use more than one page for the ring buffer (passing
'2' as the last parameter of xc_map_foreign_batch(), and so on), or
am I limited to 1 page by design?

You should be able to as many as you want. Are you hitting any
particular issues?

Haven't tried it yet, I've just noticed that all the example code using it hardcoded '1' as the number of pages it asks for, xenaccess.c has a comment to the effect of "/* Map the ring _page_ */", and so on.
