NawderOS Minimal Kernel Patch (MVP) 🧠

(RTT‑Aware Instrumentation Baseline)

This patch does one thing well:

It proves that RTT‑aligned observation can live inside the kernel without changing kernel behavior.

No enforcement.
No policy.
No cleverness.

Just signals.

MVP Goals#

This patch must:

• Compile cleanly on Linux 6.x
• Emit at least one RTT badge at boot
• Touch as few kernel files as possible
• Be removable without side effects
• Be understandable in one sitting 🙂

What This MVP Implements#

✔️ One RTT concept#

Substrate baseline observation

✔️ One module#

substrateAudit

✔️ One badge#

SUBSTRATE_BASELINE

That’s it.

Everything else comes later.

Patch Overview#

Files Touched#

• init/main.c — boot‑time hook
• include/linux/nawderos.h — RTT definitions
• kernel/nawderos.c — badge emission logic
• kernel/Makefile — build integration

1️⃣ Header: RTT Definitions#

include/linux/nawderos.h

#ifndef _LINUX_NAWDEROS_H
#define _LINUX_NAWDEROS_H
 
#define NAWDEROS_VERSION "0.1.0"
#define RTT_BADGE_SUBSTRATE_BASELINE "SUBSTRATE_BASELINE"
 
void nawderos_emit_badge(const char *badge_type,
                         const char *module,
                         const char *context);
 
#endif

This keeps RTT visible but lightweight.

2️⃣ Badge Emission (Minimal)#

kernel/nawderos.c

#include <linux/kernel.h>
#include <linux/nawderos.h>
 
void nawderos_emit_badge(const char *badge_type,
                         const char *module,
                         const char *context)
{
    printk(KERN_INFO
        "[NAWDEROS][BADGE] type=%s module=%s context=%s\n",
        badge_type,
        module,
        context ? context : "none");
}

Yes — this uses printk.

That’s intentional.

Tracepoints come later.
First, we prove the concept.

3️⃣ Boot‑Time Hook#

init/main.c

Add near the end of start_kernel():

#include <linux/nawderos.h>
 
...
 
nawderos_emit_badge(
    RTT_BADGE_SUBSTRATE_BASELINE,
    "substrateAudit",
    "kernel_boot"
);

This emits exactly one badge per boot.

No loops.
No conditions.
No risk.

4️⃣ Build Integration#

kernel/Makefile

Add:

obj-y += nawderos.o

That’s it.

What You’ll See at Runtime 👀#

On boot:

[NAWDEROS][BADGE] type=SUBSTRATE_BASELINE module=substrateAudit context=kernel_boot

That single line proves:

• RTT concepts are present
• The kernel is instrumented
• Badges are real
• Nothing broke 🙂

Why This MVP Is Correct#

This patch:

• Demonstrates RTT without overreach
• Matches the documentation exactly
• Gives students something concrete to see
• Creates a stable anchor for future work
• Avoids premature abstraction

Most importantly:

It makes RTT observable, not theoretical.

What Comes Next (Not in This Patch)#

Deliberately excluded:

• Tracepoints
• /proc/nawderian
• Scheduler hooks
• Memory corridors
• Userspace collectors

Those belong in v0.1.x, not the baseline.

How This Aligns with v0.1.0#

This patch is the physical manifestation of the v0.1.0 tag:

• RTT is present
• Coherence is observable
• Lineage is preserved
• Scope is controlled

Nothing more is required for the baseline.
