[Xen-devel] [PATCH] Add DOM0_GETDOMAININFOLIST op for bulk retrieval of domain info
The attached patch adds a new dom0_op, DOM0_GETDOMAININFOLIST. This operation allows retrieval of the domain info structures for all domains in one hypercall. Using a small test program, on a system with 97 domains with non-contiguous domain IDs, I found that with this hypercall I could retrieve the full array of info structures 12840 times per second, an improvement from 2380 times per second with the DOM0_GETDOMAININFO op. The patch also adds a libxc wrapper for this new hypercall. - Josh Triplett _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
