System Requirements
===================

Xilinx Accelerator Card
-----------------------

1. VCU1525
2. U200
3. Versal CPM4 XCVC1902
4. Versal CPM5 XCVP1202

Host System
-----------

x86_64 host system with at least one Gen 3x16 PCIe slot and minimum 64GB RAM
on same CPU node for 2K queues. For accomodating 4K queues in Versal CPM5 ~256GB RAM would be required.
For VM testing, host system must support virtualization and it must be enabled in the BIOS.


Host System Configuration
-------------------------

QDMA DPDK driver latest release is verified on following host system configuration for PF and VF functionality

**Notes**: 

- When assigning the 2048 queues to PFs users shall make sure the host system configuration meets the requirement given above. If users want to enable iommu(iommu=on), make sure suffiecient Huge pages are available to support the 2048 queues.

- Versal CPM5 design supports 4096 queues. Users shall make sure the host system configuration meets the memory requirements to accomodate 4096 queues.

- QEMU is a hosted virtual machine monitor which emulates the machine's processor through dynamic binary translation and provides a set of different hardware and device models for the machine, enabling it to run a variety of guest operating systems.This is used to emulate the virtual machines and enables the users to attach virtual functions to virtual machines.
