A | Lokesh Kanagaraj is back in prep mode. The director has slipped straight into groundwork for his seventh film, currently referred to as LK7. A team member posted a photo from an early meet, confirming that the director has restarted the cycle that usually precedes one of his big canvas projects. The curiosity around LK7 is understandable. Every move from Lokesh tends to trigger an online theory storm and this one is no exception.Fans initially assumed LK7 would simply be Kaithi 2. The sequel has finally rolled into pre-production after years of anticipation, which only strengthens the possibility. At the same time, there is steady chatter from Telugu industry trackers that Lokesh has been courted for a major Telugu language project. If that becomes official, it would mark his first direct entry into Tollywood. For now the director has maintained radio silence, leaving both conversations wide open.

Directed by Arun Matheswaran, the film casts him as Devadas with Wamiqa Gabbi as Chandra. Sun Pictures is producing the project following their collaboration on Coolie. Prep work for DC has been steady, with Lokesh attending readings and workshops as he balances the shift from behind the camera to in front of it.He was earlier attached to direct Rajinikanth in Thalaivar 173 for Raaj Kamal Films International but stepped away after reported creative differences. The move created room for him to arrange his next phase which now includes LK7, Kaithi 2 and DC.

The cast featured Nagarjuna, Soubin Shahir, Upendra, Shruti Haasan, Sathyaraj and Rachita Ram, with Aamir Khan and Pooja Hegde making short appearances. Audience reaction, however, was divided. Some fans enjoyed the scale and swagger but a sizeable section criticised the uneven screenplay and the lack of the trademark precision seen in Kaithi and Vikram. Critics echoed the same concerns. Despite this, strong festival weekend numbers and sustained turnout eventually pushed the film into commercial success territory.With multiple projects now moving in parallel and a conscious effort to recalibrate after Coolie, Lokesh Kanagaraj seems set for a more controlled and deliberate next chapter.Also Read: South Indian Legends Mourn Dharmendra。（via Phoronix）本周早些时候，AMD 发布了 GNU 编译器集合（GCC）的基础支持代码，扩展了对 Zen 4 微架构的支持。相信随着时间的推移，该公司还会带来与 Znver4 相关的更多改进。

B | 更新后的 Zenver4 基础启用补丁，与 Zenver3 基本相同、但添加了对 AVX-512 新指令集的支持 —— 即 AVX512F、AVX512DQ、AVX512IFMA、AVX512CD、AVX512BW、AVX512VL、AVX512BF16、AVX512VBMI、AVX512VBMI2、GFNI、 AVX512VNNI、AVX512BITALG 和 AVX512VPOPCNTDQ。（来自：LKML）除了 AVX-512，Zen 4 相较于 Zen 3 的架构差异并不大。不过相较于消费级市场，这项特性显然更适用于新一代 EPYC（霄龙）Genoa 服务器平台的使用场景。
