Avi, Marcelo, currently userspace can access guest registers via several ioctls. Some of these registers might be useful very often. Here the system call overhead for ioctl can make an exit more expensive than necessary. In a discussion with Alex Graf we concluded that it might be beneficial to have a subset of registers available in kvm_run. (The ioctls will also be available).
This series provides a prototype implementation together with two example users for s390. Opionions? -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
