The updated site covers syscalls from Linux 3.3 to 7.3 across 27 architectures and offers kernel selectors plus JSON downloads of syscall history.

A Show HN post announces an update to a site that compiles Linux system call tables for 27 architectures. The tables include syscall numbers, arguments, registers, and full addition/removal history from the kernel source. An API and direct JSON files are provided for querying any kernel release.

Key facts
  • 27 architectures supported from 3.3 to 7.3
  • JSON exports record when each syscall was added or removed
  • Calling conventions and instructions listed per architecture
  • Data sourced directly from Linux kernel source and man pages
  • Kernel selector for each architecture page
