procfs

This document describes the procfs filesystem in the Kyronix kernel. It is the child of Filesystems.

Source

kernel/fs/procfs.c

Overview

procfs is an in-memory filesystem mounted at /proc that exposes process and kernel information. It provides a read-only view of system state.

Mount Point

/proc

Entries

EntryDescription
/proc/<pid>/Per-process information directories
/proc/self/Symlink to current process
/proc/meminfoMemory usage statistics
/proc/versionKernel version string
/proc/uptimeSystem uptime

Implementation

procfs nodes are dynamically generated on lookup. The filesystem does not persist data to disk; all information is gathered from kernel state at access time.
