Release Notes: LTS

This document outlines changes introduced to the Intel® software for general-purpose GPU capabilities in LTS releases. As the software includes several different projects, the changes for each release are grouped by project.

To install packages for the preferred LTS release, refer to the installation guide for your distribution. For a list of packages published on repositories.intel.com/gpu for each release and operating system, see Provided Packages.

  • Ubuntu 22.04

  • SUSE Linux Enterprise (SLES): 15 SP4, 15 SP5, and 15 SP6

Improvements

Intel® Graphics Driver Backports for Linux* OS (i915) and Intel GPU Firmware

Updated the Graphics Micro Controller (GuC) to version 70.44.1.

2025-04-02

The 2350.145 release supports the following operating systems:

  • Red Hat Enterprise Linux (RHEL): 8.8, 8.10, 9.2, 9.4, and 9.5

  • Ubuntu 22.04

  • SUSE Linux Enterprise (SLES): 15 SP4, 15 SP5, and 15 SP6

Features

General

Introduced support for RHEL 9.5.

Changes

General

Updated the signing key for KMD prebuilds to enhance security and ensure continued reliability. This key ensures that only trusted kernel-level software can run during the boot process. The new key, valid for one year, will be used to sign all new KMD module releases. If you use secure boot, you need to download and install a new Distinguished Encoding Rules (DER) certificate to maintain compatibility. If you do not use secure boot, no action is required.

Improvements

Intel® Graphics Driver Backports for Linux* OS (i915)

  • Updated the Graphics Micro Controller (GuC) to version 70.40.1.

  • Fixed an issue causing a memory error.

  • Introduced page fault handling improvements.

  • Implemented a workaround to address an encoder issue causing errors. The workaround adds support for the G8 power state in ATS-M to reduce idle power consumption.

  • Skipped the HuC microcontroller authentication register check and marked HuC as available if preloaded.

Intel® Graphics Compiler

  • Enabled optimizations for the -cl-opt-disable and -ze-opt-disable API options.

  • Fixed a crash issue that occurred during copy elimination.

  • Initialized address register to prevent unaligned cross-GRF access.

  • Replaced %opt with opt in the vector compiler.

Intel GPU Firmware

Updated the Graphics Micro Controller (GuC) to version 70.41.0.

Known issues

  • When installing drivers from Intel repositories on LTS, the repositories may contain older package versions than those in public repositories. To ensure the correct versions are installed from Intel repositories, we recommended adding priority=98 to the repository configuration. This helps effectively manage package version selection.

  • For application workloads using HBM on SPR, ensure that the UMD policy chooses I915_GEM_CREATE_MPOL_PREFERRED instead of i915_GEM_CREATE_MPOL_BIND when calling ioctl. This can be achieved by replacing --membind=8 with --preferred=8 in the numactl command.

2025-01-28

The 2350.136 release supports the following operating systems:

  • Red Hat Enterprise Linux (RHEL): 8.8, 8.10, 9.2, and 9.4

  • Ubuntu 22.04

  • SUSE Linux Enterprise (SLES): 15 SP4, 15 SP5, and 15 SP6

Improvements

Intel® Graphics Driver Backports for Linux* OS (i915)

  • Resolved an issue where uninstalling the i915-dkms package on RHEL 9.4 with multiple kernels resulted in errors.

  • Resolved a DKMS compilation issue on SLES SP6.

Intel® Video Processing Library GPU Runtime

Enabled support for ARGB input format in AV1 encoding on Alchemist and Arctic Sound M GPUs.

Known issues

For the application workload using HBM on SPR, ensure that the UMD policy chooses I915_GEM_CREATE_MPOL_PREFERRED instead of i915_GEM_CREATE_MPOL_BIND when calling ioctl. You can do it by replacing “–membind=8” with “–preferred=8” in the numactl command.

2024-12-04

The 2350.125 release supports the following operating systems:

  • Red Hat Enterprise Linux (RHEL): 8.8, 8.10, 9.2, and 9.4

  • Ubuntu 22.04

  • SUSE Linux Enterprise (SLES): 15 SP4, 15 SP5, and 15 SP6

Features

Intel® Graphics Driver Backports for Linux* OS (i915)

Enabled the survivability mode that provides a software recovery option for GPU firmware updates as an alternative method when driver initialization fails to complete.

Improvements

Intel® Graphics Compute Runtime for oneAPI Level Zero and OpenCL™ Driver

Resolved a timeout issue in certain PyTorch distributed FSDP operations that occurred after the compiler upgrade.

Intel® Graphics Driver Backports for Linux* OS (i915)

  • Fixed an issue causing failures when querying GPU metrics on Intel Arc Series GPUs.

  • Corrected the ordering of Translation Lookaside Buffer (TLB) flush and invalidate operations.

  • Resolved issues with the tracking of concurrent evictions and the unintended eviction of objects that had already been migrated from the target memory region.

  • Resolved an assertion failure by updating the eviction logic to modify only the tail of the eviction list.

  • Fixed an issue causing node crashes when profiling an application with VTune.

Known issues

For the application workload using HBM on SPR, ensure that the UMD policy chooses I915_GEM_CREATE_MPOL_PREFERRED instead of i915_GEM_CREATE_MPOL_BIND when calling ioctl. You can do it by replacing “–membind=8” with “–preferred=8” in the numactl command.

2024-11-06

The 2350.105 release supports the following operating systems:

  • Red Hat Enterprise Linux (RHEL): 8.8, 8.10, 9.2, and 9.4

  • Ubuntu 22.04

  • SUSE Linux Enterprise (SLES): 15 SP4, 15 SP5, and 15 SP6

Improvements

Intel® Graphics Driver Backports for Linux* OS (i915)

Resolved a compilation issue encountered during kernel updates on RHEL 8.10.

Known issues

For the application workload using HBM on SPR, ensure that the UMD policy chooses I915_GEM_CREATE_MPOL_PREFERRED instead of i915_GEM_CREATE_MPOL_BIND when calling ioctl. You can do it by replacing “–membind=8” with “–preferred=8” in the numactl command.
