This directory implements syscall dispatch and handler entry points that bridge userspace ABI requests to kernel subsystems.

Summary

  • Defines syscall numbers and dispatch tables.

  • Implements handlers for process, memory, and file-descriptor operations.

  • Connects architecture syscall traps to generic kernel services.

Typical Work in This Area

  • Add new syscall handlers.

  • Improve ABI compatibility and argument validation.

  • Harden return/error behavior and scheduler interactions.
