As the Linux 3.4 has x32 ABI support, we think it's the right time for us to evaluate x32 ABI for virtualization and the cloud. The x32 ABI provides a model in x86-64 psABI with 32-bit address space, with 16 64-bit integer registers (8 additional integer registers), 8 additional SSE registers, etc., compared to the conventional x86 32-bit ABI. We look at performance improvements and memory saving gained by x32 applications, and discuss how x32 can be helpful for Xen and the clouds.
