    * **Intel**
+     * Intel Arc B580 Graphics is compatible with the Xe2 driver architecture.
+     * Upgrading the kernel to version 6.11 or its minor variations enables Xe2 driver support.
+     * The DEB package will be installed during node onboarding.

+        https://dgpu-docs.intel.com/devices/hardware-table.html
+     * Refer to the official documentation for driver installation. DEB package install GPU drivers as part of rolling updates.
+
+       https://dgpu-docs.intel.com/driver/installation-rolling.html
+
+     * **Ubuntu-22.04** 
+         * Ubuntu 22.04 officially supports the 6.8 Linux kernel, whereas the B580 requires the 6.11 Linux kernel. To install the driver for the B580, a custom 6.11 kernel is required.
+         * The driver installation instructions for Ubuntu 22.04 were ineffective for B580, resulting in a failed card enumeration.
+
+     * **Ubuntu-24.04 Desktop**
+         * Ubuntu Desktop 24.04.2 includes the xe driver by default.
+         * For Any additional compute and media package intel provide PPA, can be installed from the official Intel site.

+            ```
+         * List the group assigned ownership of the render nodes and the groups you are a member of.There are specific groups that users must be a part of to access certain functionalities of the GPU. The render group specifically allows access to GPU resources for rendering tasks without giving full access to display management or other potentially more sensitive operations.
+            ```
+            stat -c "%G" /dev/dri/render*
+            groups ${USER}

+         * If you are not a member of the same group used by the DRM render nodes, add your user to the render node group.
+            ```
+            sudo gpasswd -a ${USER} render
+            ```
+         * Change the group ID of the current shell.
+           ```
+           newgrp render
+           ```

      * Existing extensions, such as the device-operator and gpu-plugin, will be updated. The Intel GPU device plugin for Kubernetes facilitates access to Intel discrete and integrated GPUs, registering resources like gpu.intel.com/i915 and gpu.intel.com/xe within a Kubernetes cluster
+     * **For EMT** : EMT should be build with 6.11* linux kernel.
+     * **For Ubuntu** : Ubuntu Server 24.04.2, equipped with the 6.11 kernel, has been validated with BMG GPU drivers. DEB packages are available as rolling updates in the official documentation.
+
    * **NVIDIA**
      * A new extension will be created to configure and install the NVIDIA GPU Operator using its Helm chart. The NVIDIA GPU Operator automates the management of all NVIDIA software components required to provision GPUs in Kubernetes, including drivers, the Kubernetes device plugin, the NVIDIA Container Runtime, and monitoring tools.
