The main rule for data access is max(CPL, RPL) ≤ DPL. For code transfers, the rules get considerably more complex -- conforming segments, call gates, and interrupt gates each have different privilege and state validation logic. If all these checks were done in microcode, each segment load would need a cascade of conditional branches: is it a code or data segment? Is the segment present? Is it conforming? Is the RPL valid? Is the DPL valid? This would greatly bloat the microcode ROM and add cycles to every protected-mode operation.
筛选这类标的的关键标准是：该公司是AI Agent的“受害者”还是“载体”？以ServiceNow为例，尽管其股价近期暴跌，但通过收购Moveworks、Armis，它正试图从“被Agent替代”转向“成为Agent平台”，这种转型若能成功，有望带来估值修复。
