Also, by adopting gVisor, you are betting that it’s easier to audit and maintain a smaller footprint of code (the Sentry and its limited host interactions) than to secure the entire massive Linux kernel surface against untrusted execution. That bet is not free of risk, gVisor itself has had security vulnerabilities in the Sentry but the surface area you need to worry about is drastically smaller and written in a memory-safe language.

Besides the Test PLA, the 386 has another PLA called the Entry PLA that maps opcodes to microcode entry points. One of its input bits is a "protected mode" flag. Many instructions have both a real-mode and a protected-mode entry point -- for instance, MOV ES, reg maps to address 009 (a single microcode line) in real mode, but to 580 (which initiates a full descriptor load with protection tests) in protected mode. The trick that makes V86 work is to define this flag as:，详情可参考91视频
