一 | 8 月 26 日消息，科技媒体 Linuxiac 昨日（8 月 25 日）发布博文，报道称 Linux 创始人林纳斯 · 托瓦兹（Linus Torvalds）借助 AI，通过 24 个调试补丁、18 次内核启动，成功排查 Intel Xe 图形驱动中的内存破坏漏洞。
二 | 托瓦兹描述本次排查过程为“地狱般的调试过程”，在其 Intel Battlemage G21（配备 16 GiB VRAM）上 GDM（GNOME 显示管理器）反复重启合成器，屏幕最终保持黑屏。 WASHINGTON -- Senate Majority Leader Chuck Schumer is headed to Israel this weekend to discuss what resources the United States can provide for its war against Hamas.Schumer, D-N.Y., is leading a bipartisan group of senators to the country “to show the United States' unwavering support for Israel,” his office said. Schumer is the first Jewish majority leader of the Senate and the highest-ranking Jewish elected official in the U.S.The visit comes as Congress is considering how much money and equipment to send to Israel and as two other high-ranking officials, Secretary of State Antony Blinken and Defense Secretry Lloyd Austin, have visited in recent days.Schumer’s office said he will meet with Prime Minister Benjamin Netanyahu, President Isaac Herzog and senior opposition figure Benny Gantz, who is part of a newly formed wartime cabinet in Israel. His office has not released the names of the senators who will be traveling with him. The majority leader just this week returned from a trip to China, where he pressured officials to condemn the brutal attack on Israel by Hamas. The U.S. officials are talking to Israeli officials about what kind of aid is needed to defend against attacks from Hamas and is seeking to avoid an expanded Middle East conflict. The Israeli military directed some 1 million civilians to evacuate northern Gaza “for their own safety and protection,” ahead of a feared Israeli ground offensive. Gaza’s Hamas rulers responded by calling on Palestinians to “remain steadfast in your homes and to stand firm” against Israel.Schumer's visit comes as the Senate is set to return to Washington on Tuesday and debate how much money and equipment to send to Israel and whether to tie an aid package with money for Ukraine in its war against Russia's invasion.。附上相关截图如下：该问题出现在 Xe DRM 驱动的 Flat CCS 内存处理环节，根源来自 get_flat_ccs_offset () 函数的地址计算。
三 | 该函数先计算保留 CCS 存储区的起始位置，再将地址向上对齐到 128 KiB 边界。
四 | 但随后，低于这个计算地址的全部空间都被 VRAM 分配器当作可用内存。这样一来，合成器首次提交 GPU 任务便失败，GDM 随即重启合成器，系统陷入黑屏。托瓦兹表示，最终修复只涉及把错误的 round_up () 改为 round_down ()。不过，定位过程远比修复代码复杂：他累计添加 24 个补丁，用于逐步增加调试信息，并启动内核 18 次，才锁定内存破坏的具体原因。
五 | 托瓦兹表示在本次调试过程中，AI 承担添加调试代码和分析输出结果等大量重复工作。在调用处理过程中，AI 多次得出该问题无法解决的结论，不过在托瓦兹的多次协调指导下，不断推进让 AI 生成新的调试工具并分析结果，直至定位底层内存破坏。调查结束后，托瓦兹还让 AI 撰写了详细的提交说明。
