LLVM is a widely used compiler infrastructure whose scale and complexity make issue resolution labor-intensive and challenging. Although large language models (LLMs) have recently achieved remarkable success in issue resolution, their effectiveness on complex system-level LLVM compiler remains largely unexplored. To address this gap, we introduce LLVM-Bench, the first large-scale benchmark for LLVM issue resolution, containing 423 real-world, ... Read more ›

We are observing huge contention on the epmutex during an http connection/rate test: 83.17% 0.25% nginx [kernel.kallsyms] [k] entry_SYSCALL_64_after_hwframe [...] |--66.96%--__fput |--60.04%--eventpoll_release_file |--58.41%--__mutex_lock.isra.6 |--56.56%--osq_lock The application is multi-threaded, creates a new epoll entry for each incoming connection, and does not delete it before the connection shutdown - that is, before the connection's fd close(). Many different threads compete frequent... Read more ›

NetBSD is the only BSD without a Vulkan stack (Mesa and Lavapipe), but that’s about to change. The effort to bring Vulkan to NetBSD is now in beta, with prebuilt binaries coming soon. Mesa configures, compiles, links, installs, and registers the Lavapipe software Vulkan driver on NetBSD 10.1 amd64, against LLVM 19.1.7. The driver (libvulkan_lvp.so, ~17 MB) installs into /usr/pkg/lib, and its ICD manifest (advertising Vulkan API 1.4) installs into /usr/pkg/share/vulkan/icd.d/, so a Vulkan load... Read more ›

Recently, I have been successful in making A/UX boot and run stable on my vintage Macintosh emulator; Snow. A/UX was Apple’s version of UNIX that ran on the 68k-based series Macs. It required a Memory Management Unit to achieve process isolation; either the optional 68851 PMMU on the original 68020-based Macintosh II or the integrated MMU in the 68030- and 68040-based machines. It also required an FPU; making it only run on the higher end machines such as the Macintosh II series and later the... Read more ›

We prove the following results. 1. First order model checking is fixed-parameter tractable on the class of finite fields, as a corollary of results of Ax on the theory of (pseudo)finite fields. 2. Every hereditary graph class first order definable in the class of finite groups is monadically stable, and thus has fixed-parameter tractable first order model checking. 3. Monadic second order model checking is not slicewise polynomial on the cla... Read more ›
Last month I posted about . Some people on Hacker News noticed that, when I showed the fastfetch result, I said I was confused with the RAM usage compared to btop and commented that fastfetch is probably more correct. I decided to enter that rabbit hole and try to understand why reporting free or used memory in a modern operating system is more complicated than it seems. Another user shared , which provide a quick explanation for the same effect on Linux. And if you want a quick answer for Fr... Read more ›

Many software bugs in network protocol implementations arise near specification boundaries, such as inputs just within or outside allowed ranges, or messages that are valid in isolation but invalid in a given state. From the SSL Heartbleed exploit to TCP Christmas Tree packets, boundary inputs have repeatedly exposed critical weaknesses, yet remain under-tested by existing techniques such as fuzzing and model-based testing. We present CornerCase... Read more ›
OxCaml, Jane Street's superset of OCaml, allows you to assert that entire call trees do not allocate on the heap with [@zero_alloc].This turns the typical process of profiling to find hot spots backwards, allowing you to track down every single allocation you might care about in a hot loop.
