 Hello! How are things going? There was lots of activity, discussions, and then - silence...

Kind regards,

> Subject: [PATCH v5 0/7] KVM: arm64: Implement API for vGICv3 live migration
> 
> This patchset adds necessary userspace API in order to support vGICv3 live
> migration. GICv3 registers are accessed using device attribute ioctls,
> similar to GICv2.
> 
> Whoever wants to test it, please note that this version is not
> binary-compatible with previous one, the API has been seriously changed.
> qemu patchess will be posted in some time.
> 
> v4 => v5:
> - Adapted to new API by Peter Maydell, Marc Zyngier and Christoffer Dall.
>   Acked-by's on the documentation were dropped, just in case, because i
>   slightly adjusted it. Additionally, i merged all doc updates into one
>   patch.
> 
> v3 => v4:
> - Split pure refactoring from anything else
> - Documentation brought up to date
> - Cleaned up 'mmio' structure usage in vgic_attr_regs_access(),
>   use call_range_handler() for 64-bit access handling
> - Rebased on new linux-next
> 
> v2 => v3:
> - KVM_DEV_ARM_VGIC_CPUID_MASK enlarged to 20 bits, allowing more than 256
>   CPUs.
> - Bug fix: Correctly set mmio->private, necessary for redistributor access.
> - Added accessors for ICC_AP0R and ICC_AP1R registers
> - Rebased on new linux-next
> 
> v1 => v2:
> - Do not use generic register get/set API for CPU interface, use only
>   device attributes.
> - Introduce size specifier for distributor and redistributor register
>   accesses, do not assume size any more.
> - Lots of refactor and reusable code extraction.
> - Added forgotten documentation
