Marc Zyngier b22498c484 Merge branch kvm-arm64/timer-vm-offsets into kvmarm-master/next ... * kvm-arm64/timer-vm-offsets: (21 commits) : . : This series aims at satisfying multiple goals: : : - allow a VMM to atomically restore a timer offset for a whole VM : instead of updating the offset each time a vcpu get its counter : written : : - allow a VMM to save/restore the physical timer context, something : that we cannot do at the moment due to the lack of offsetting : : - provide a framework that is suitable for NV support, where we get : both global and per timer, per vcpu offsetting, and manage : interrupts in a less braindead way. : : Conflict resolution involves using the new per-vcpu config lock instead : of the home-grown timer lock. : .
