Linux kernel syscall tables

Live at syscalls.mebeim.net.

High-quality browsable tables of system calls implemented by the Linux kernel on various architectures and ABIs. Powered by Systrack, a Linux kernel syscall implementation tracker.

Features:

• Sortable tables for multiple architectures, ABIs, and kernel versions.
• URL parameters to share/link a specific table.
• Direct links to syscall definitions within the kernel source code via Bootlin Elixir Cross Referencer.
• Parameter types, names and corresponding ABI calling convention registers.
• Listed Kconfig options for optional syscalls.
• Downloadable kernel configurations to build kernels with the same syscalls listed in the tables.

Building

To build this static website, you will need Python 3, and optionally the fonttools and brotli modules. Run the following commands the root of this repository:

# Required: copy over db files and build db index
./scripts/build_web_db.py
# Opional: build emoji font (needs fonttools + brotli)
./scripts/build_web_fonts.sh

The static website is now available in the www/ folder. You may quickly test it locally using one of these commands:

$ python3 -m http.server -d www -b 127.0.0.1 8080
$ ruby -run -ehttpd -- -p 8080 www
