Any updates? :-) I have gotten side-tracked by the automatic NUMA balancing work, but Michael Tsirkin has been doing some work on reducing idle latencies. - -- All rights reversed -BEGIN PGP SIGNATURE- Version: GnuPG v1 Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJTpYFnAAoJEM553pKExN6DcDcH/1UlBofa3KmGaercqfBk19Sj 78T8JgiAog4WBanFn3znVqbvdu1icMztVdUw/CoqVwgyeRmgyfXt5uf1lHtCe7zx HS/BDIAYJSXt0uXPd7bBUThFdTLusL/VSf7WBV6ex3Qcw8qywBooS2VdA4wYP8t4 oMclOSR6imjhwSPYLP+723duzYowu35wXC1Fojhrm1AidAbLSIiClVGrDtkFjp5p iuM+J6hHDPH3E/hwSWYE8EBeOC5CrvhmMdguv+7R4Z5qI9Qz+K6Ol8U1P33BcDfL IXMoW/76UUEwmK3BOjTvYFUYJTUb94znY/e3q3zK1UZCoIpMqUyUjLUNiEZKjXc= =rmno -END PGP SIGNATURE- -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I thought you were interested in bringing ivshmem up to a level where distros feel comfortable enabling and supporting it. Getting there will require effort from you to audit, clean up, and achieve test coverage. That's what a maintainer needs to do in a case like this.

status of reducing context switching overhead in KVM
Hi, Rik I saw your presentation at last year 2013 kvm submit. (http://www.linux-kvm.org/wiki/images/2/27/Kvm-forum-2013-idle-latency.pdf). You said there will have some patches later, but I didn't find them. Are you continuing to do the optimization work? Any updates? :-) Many thanks.
