Subject: [PATCH 0/2] LoongArch: Add steal time support
Date: Tue, 26 Mar 2024 16:06:23 +0800 [thread overview]
Message-ID: <20240326080625.898051-1-maobibo@loongson.cn> (raw)
Para-virt feature steal time is added in both kvm and guest kernel side.
It is silimar with other architectures, steal time structure comes from
guest memory, also pseduo register is used to save/restore base address
of steal time structure, so that vm migration is supported also.
