[PATCH v3 0/8] KVM: nSVM: ondemand nested state allocation + smm fixes

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

 



This patch series does some refactoring and implements on demand nested state area
This way at least guests that don't use nesting won't waste memory
on nested state.

This patch series is based on patch series '[PATCH 0/3] Few nSVM bugfixes'
(patch #7 here should have beeing moved there as well to be honest)

The series was tested with various nested guests, and it seems to work
as long as I disable the TSC deadline timer (this is unrelated to this
patch series)

I addressed the review feedback from V2, and added few refactoring
patches to this series as suggested.

Best regards,
