Cleaning Up A Mess: Linux 6.9 Likely To Land Rework Of x86 CPU Topology Code

Phoronix - Sat, 02/17/2024 - 01:38
Longtime Linux kernel developer Thomas Gleixner with Intel-owned Linutronix has been spending much time over the past several months reworking the Linux kernel's x86 CPU topology evaluation code. This is to clean-up a mess of aging kernel code as well as some areas of the code being incorrect in today's era of hybrid Intel Core processors with a mix of P / E cores with the E cores lacking SMT/HT and thus throwing off prior kernel assumptions. With the code now queued up in a TIP branch today, it looks like that CPU topology rework could be good to go with Linux 6.9...

Meta Continues Working On BOLT'ing The Linux Kernel For Greater Performance

Phoronix - Fri, 02/16/2024 - 23:16
Merged to the LLVM compiler stack two years ago was the BOLT tool for optimizing the layout of generated binaries for offering even greater performance than the likes of Profile Guided Optimizations (PGO) alone. BOLT had been in development for years by Facebook/Meta engineers and has continued to be improved upon for enhancing the code layout of binaries to yield enhanced performance. Recently there's been renewed work on using BOLT to optimize Linux kernel images...

Intel Making It Easier To Reproduce Linux GPU Hangs On Real Hardware

Phoronix - Fri, 02/16/2024 - 21:45
Intel engineers working on their open-source Mesa OpenGL/Vulkan driver code currently replay captured error state / GPU hangs using a simulator, but a new patch proposal allows for replaying GPU hangs on the actual hardware. In turn this will hopefully help Intel driver developers better address some real-world issues...
