Hi all,

Is any one knew,whether mainline kernel and psci plan to support hibernation on arm64 architecture now?

Suspend-to-disk relies on PSCI SYSTEM_OFF to be implemented and does not require any additional calls in ATF.

Suspend to disk ARM64 kernel patches are under review (series below on LAKML), I hope you can help us review and test them.

Thanks a lot,
