[Minios-devel] [UNIKRAFT PATCHv5 45/46] plat/kvm: Implement time_block_until for arm64

[Wei Chen <wei.chen@xxxxxxx>]

From: Wei Chen <Wei.Chen@xxxxxxx>

As we haven't implement full functions for timer for arm64.
But this function is needed by Unikraft. So we impplement
a temporary function to make compiler happy.
