rmNVMe-IP with Custom DMA on PetaLinux Demo

Overview

This document demonstrates how to achieve 3000++ MB/s NVMe performance with full Linux filesystem access using rmNVMe-IP on a PetaLinux-based FPGA demo from Design Gateway - DG rmNVMe-IP PetaLinux demo.

Introduction

The rmNVMe-IP with Custom DMA on PetaLinux demo showcases a high-performance random-access NVMe host system built on a custom DMA datapath, delivering over 3000 MB/s while operating as a fully Linux-compatible block device. Users can evaluate I/O performance, verify data integrity, and execute NVMe management commands directly from the terminal.

Comparison: DG rmNVMe-IP vs DG NVMe-IP on PetaLinux

IP Name	rmNVMe-IP (this demo)	NVMe-IP
Device Type	Block	Character
Design Target	Kernel-compatible, Filesystem-supported	Performance-critical, Resource-optimized
Performance Focus	Random access	Sequential access
Operation Support	Read/Write simultaneously	Single Operation

Note: See the DG NVMe-IP on PetaLinux Repository

Key Features:

• High-Performance Random Access:
  Achieve 3000++ MB/s real-world throughput with both raw and filesystem access.

• Linux Block Device Support:
  The DG rmNVMe driver provides a true /dev/dgnvmeblk* block interface—format, mount, and use like a standard Linux drive.

• Zynq UltraScale+ Optimization:
  Fully hardware-accelerated NVMe datapath with low CPU load for embedded systems.

• Seamless Integration with PetaLinux:
  Includes driver, block device, and example applications ready to run on boot.

• Real-World Workflow Demonstration:
  Covers performance tests, data integrity, NVMe commands, and user application execution.

About This Demo

This demo showcases Design Gateway’s rmNVMe-IP running on PetaLinux, delivering high-speed NVMe storage with full Linux filesystem capability. After booting from the SD card, users can run performance tests, validate data, and execute NVMe commands directly from the terminal using the included tools.

Test Environment

The demo runs on a PetaLinux-based FPGA system equipped with an NVMe SSD. Here are the required components:

1. FPGA development board: ZCU106
2. PCIe adapter board: AB17-M2FMC
3. SD Card
4. Serial Console

Running the Demo

1. Boot the FPGA board from SD card and log in with

   Login:		root
   Password:	root

2. Verify the driver and device with lsmod and ls /dev/dgnvmeblk*.
3. Once the system is ready, simply follow the Demo Instruction document to run all tests and evaluations.
