UROAM - Unified RAM Optimization and Management Framework

Overview

UROAM is a production-grade, low-level system framework for Linux that optimizes RAM utilization across heterogeneous workloads including AI/ML, gaming (Steam/Proton), rendering, and general applications.

Features

Cross-Architecture Support: x86_64, ARM64, ARM32, RISC-V64, PPC64LE, S390X, LoongArch64
Architecture Abstraction Layer (AAL): Runtime detection of page size, hugepages, cache line, SIMD, NUMA, endianness
Intelligent Classification: Real-time workload detection (AI, Gaming, Compilation, Interactive, Background, Idle)
Adaptive Optimization: Compression (ZRAM/Zswap), deduplication (KSM), cache management
Gaming Mode: Steam/Proton/Wine detection, mlock critical pages, preserve shader cache
Idle Optimization: Automatic cold page compression, cache dropping, THP hints
Transparent Operation: No application modifications required
Performance Focused: <2% CPU overhead, <1ms latency impact
PolicyKit Integration: Fine-grained permission control for desktop environments

Components

1. Architecture Abstraction Layer (AAL)

Runtime detection of CPU features (SIMD: SSE→AVX-512, NEON, RVV)
Page size detection (4KB, 16KB, 64KB, 2MB, 1GB)
Cache line size detection
NUMA topology detection
Portable atomics and memory barriers
Cross-architecture byte-swap primitives

2. Kernel Module (`uroam.ko`)

MGLRU support hooks
Memory pressure monitoring via procfs
Transparent Hugepage management
KSM integration
Workqueue-based periodic scanning

3. eBPF Module

Memory allocation tracking (__alloc_pages_nodemask, kmem_cache_alloc)
mmap/brk system call interception
Perf event output for userspace analysis

4. Daemon (`uroamd`) - Written in Rust

Initializes: Config → AAL → Kernel → ZRAM → Profile → Classification
Polls /proc every 500ms
Manages OOM scores and cgroups v2
Unix socket IPC for CLI communication (/run/uroam/uroamd.sock)
JSON-RPC 2.0 API for programmatic control

5. CLI (`ramctl`) - Written in Rust

status - Show current memory status (with --json output)
optimize - Trigger immediate optimization
profile set/get/list - Manage workload profiles
clean - Aggressive memory cleanup (with confirmation)
monitor - Real-time monitoring mode (with --interval)
zram status/reset - ZRAM control
game detect/force - Gaming mode management
idle force/cancel - Idle mode control
config show/validate/reload - Configuration management

6. PolicyKit Integration

Read-only commands (status, monitor, profile get): No special permissions needed
Modifying commands (profile set, optimize, clean): Require authentication
Authentication methods: sudo (traditional) or PolicyKit (desktop integration)
Policy actions: org.uroam.* (profile-set, optimize, clean, config-reload, zram-control)

Profiles

Profile	Swappiness	ZRAM Algo	ZRAM %	KSM	THP	Cache Pressure
AI	5	zstd	50%	Yes	always	100
Gaming	1	lz4	30%	No	always	50
Balanced	60	lz4	25%	Yes	madvise	100
Powersaver	90	zstd	60%	Yes	always	25

Reloading Configuration

After editing /etc/uroam/uroam.toml:

# Validate configuration first
ramctl config validate

# Reload configuration
ramctl config reload

PolicyKit Integration

UROAM uses PolicyKit (polkit) for fine-grained permission control on desktop environments.

How It Works

Read-only commands (status, monitor, profile get): No special permissions needed
Modifying commands (profile set, optimize, clean): Require authentication

Using PolicyKit

Desktop Environment (GNOME, KDE, etc.)

When running ramctl from a terminal in a desktop environment:

# This will trigger a polkit authentication dialog
ramctl profile set gaming

A system dialog will appear asking for your password.

Command Line (SSH, TTY)

# Use sudo for command-line environments
ramctl profile set gaming

PolicyKit Actions

Action	Description	Default Permission
org.uroam.profile-set	Change optimization profile	Administrator
org.uroam.optimize	Trigger optimization	Administrator
org.uroam.clean	Clean memory	Administrator
org.uroam.config-reload	Reload configuration	Administrator
org.uroam.zram-control	Control ZRAM devices	Administrator

API Reference

UROAM daemon (uroamd) exposes a JSON-RPC 2.0 API over a Unix domain socket.

Connection Details

Protocol: JSON-RPC 2.0
Transport: Unix domain socket
Socket Location: /run/uroam/uroamd.sock

Example API Call

# Using socat
echo '{"jsonrpc":"2.0","method":"status","params":{},"id":1}' | socat - UNIX-CONNECT:/run/uroam/uroamd.sock

# Using Python
python3 -c "
import socket, json
s = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
s.connect('/run/uroam/uroamd.sock')
s.sendall(json.dumps({'jsonrpc':'2.0','method':'status','params':{},'id':1}).encode())
print(s.recv(4096).decode())
"

For complete API documentation, see docs/api.md.

Testing
