“Almost Unlimited Modern C++ in Kernel-Mode Applications”
summary
Describes running Modern C++ on RTX kernel-mode where Visual C++ lacks DLL support and standard headers yield unresolved externals; fixes include providing a rand_s shim, custom thread library and trimmed filesystem/path implementations. Thread stacks are tiny (8KB thread stacks on RTX), std::thread and condition variables often fail, and thread‑safe static init can crash. Exceptions work but allocating during throw forces Windows bookkeeping and breaks timing. Implements MSR reads to build a private MSR-based PMU and links Fortran and Lua runtimes successfully.
