[RFC PATCH 00/12] arm64: SVE guest support test hacks

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This series, based on kvmtool master [1], contains development hacks
to accompany the recently posted v4 SVE guest support series for the
Linux kernel [2].

This is not proposed for upstreaming in its current form, but some
things are probably close to being appropriate for upstream.

Comments and review welcome (but don't sweat the details too much).

git://git.kernel.org/pub/scm/linux/kernel/git/will/kvmtool.git master

Specifically, commit fdd26ecb4bc5 ("kvm-cpu: Pause vCPU in signal handler").
