不可忽视的是,These instructions are quite handy - one instruction is smaller and faster than two - however, there's an issue. When code is running on the AArch64 architecture on top of a hypervisor, and the memory region is set to trap into the hypervisor (say, because it's a virtual UART that the hypervisor is emulating on behalf of the guest OS), the hypervisor gets told about the load or store, and the address, but doesn't get told about the writeback. This then leads to misexecution of the program, because the register isn't updated as it should be. The workaround safe-mmio uses is to have their own functions for volatile reads and writes, which are implemented with inline assembly using instructions that do not perform register writeback.

总的来看,OpenBSD正在经历一个关键的转型期。在这个过程中,保持对行业动态的敏感度和前瞻性思维尤为重要。我们将持续关注并带来更多深度分析。
