Chapter 7 Release-Specific Information for Oracle Linux 8.4 (aarch64)

The following information applies specifically to the Oracle Linux 8.4 (aarch64) release.

For general information and instructions, as well as any known issues that may apply to the 64-bit Arm (aarch64) platform, refer to the previous chapters of these release notes.

7.1 System Requirements and Limitations (aarch64)

To determine whether your hardware is supported on the current Oracle Linux 8 release, check the Hardware Certification List at https://linux.oracle.com/hardware-certifications. Note that hardware is added to the list as it becomes available and is validated on Oracle Linux.

7.2 Shipped Kernel (aarch64)

The Oracle Linux 8.4 (aarch64) release ships with Unbreakable Enterprise Kernel Release 6 (UEK R6). This kernel is currently the only kernel that is supported on the 64-bit Arm (aarch64) platform.

The default UEK kernel version that is shipped with Oracle Linux 8.4 (aarch64) is:

kernel-uek-5.4.17-2102.201.3.el8uek

Unbreakable Enterprise Kernel Release 6 (UEK R6)

The Oracle Linux release is tested as a bundle, as shipped on the installation media image. When installed from the installation media image, the minimum kernel version that is supported is the kernel that is included in the image. Note that downgrading kernel packages is not supported, unless specifically recommended by Oracle Support.

7.3 New Features (aarch64)

The following new features are specific to the 64-bit Arm (aarch64) platform. See Chapter 4, New Features and Changes for all of the new features in Oracle Linux 8.4, most of which are also supported on the 64-bit Arm (aarch64) platform.

7.4 VNC Remote Console Available as Technology Preview on Arm Platform

In this release, the Virtual Network Computing (VNC) remote console is available as a technology preview on the 64-bit Arm (aarch64) platform only. The remaining components of the graphics stack are unverified on this platform.

7.5 Known Issues (aarch64)

Currently, there are no known issues that apply to the 64-bit Arm (aarch64) platform only. For known issues that apply to the x86_64 platform, which may also apply the 64-bit Arm (aarch64) platform, see Chapter 5, Known Issues.

For information about issues you might encounter when running UEK R6 on the 64-bit Arm (aarch64) platform, see Unbreakable Enterprise Kernel: Release Notes for Unbreakable Enterprise Kernel Release 6 Update 2.

7.6 Installation and Availability (aarch64)

The following information applies to installing Oracle Linux 8.4 (aarch64). For general installation and availability information, and information that applies specifically to the x86_64 platform, see Chapter 6, Installation and Availability.

Oracle Linux 8.4 (aarch64) is made available as an ISO image (OracleLinux-R8-U4-Server-aarch64-dvd.iso), which can be used for a standard installation on generic 64-bit Armv8 hardware. This ISO has been tested on Arm hardware and is engineered for use with Ampere™ eMAG™-based EVK platform and the Marvell ThunderX2® processor. For the latest hardware that is validated for Oracle Linux 8.4 (aarch64), refer to the Hardware Certification List at https://linux.oracle.com/hardware-certifications. Note that hardware is listed as it becomes available.

You can load the ISO image from local media, such as DVD-ROM or USB flash drive; or, you can perform a network-based kickstart installation by using PXE. If you perform a network-based installation and you want to access the graphical interface for the installer, you must change the kernel boot parameters to enable VNC. For example, to enable VNC, set the inst.vnc boot option, and then set the network address to ip=eth0:dhcp at boot.

The Oracle Linux 8.4 (aarch64) ISO image is also available from the Oracle Software Delivery Cloud at https://edelivery.oracle.com/.

The latest Oracle Linux 8.4 (aarch64) packages are available from ULN and the Oracle Linux yum server. To explore the channels that are available on ULN, log in to https://linux.oracle.com/ and then view the Channels option.

You can also obtain the latest Oracle Linux 8 (aarch64) packages from the Oracle Linux yum server at https://yum.oracle.com/. Note that the Oracle Linux yum server does not provide equivalent repositories for some of the channels that are available on ULN. These channels provide non-open source packages.

The default boot kernel for fresh installations of Oracle Linux 8 (aarch64) is the Unbreakable Enterprise Kernel Release 6 (UEK R6). Note that UEK R6 is the only supported kernel for the aarch64 platform in this release. For more detailed information about UEK R6, see Unbreakable Enterprise Kernel: Release Notes for Unbreakable Enterprise Kernel Release 6 Update 2.
