AMD GPU Driver (amdgpu) 30.20.0 release notes

AMD GPU Driver (amdgpu) 30.20.0 release notes#

The release notes provide release highlights and resolved issues since the previous AMD GPU Driver release (30.10.2).

Release highlights#

The following are notable new features and improvements in AMD GPU Driver 30.20.0.

Operating system and hardware support changes#

For compatibility between AMD GPU Driver, ROCm, GPUs, and operating systems, see the Compatibility matrix.

Partitioning#

AMD GPU Driver 30.20.0 adds NPS2 + CPX partitioning support for AMD Instinct MI355X and MI350X. NPS2 splits the GPU’s memory into two NUMA domains. CPX (Core Partitioned X-celerator) is a compute partitioning mode that divides the GPU’s compute complexes (XCDs) into eight isolated logical devices. Each partition operates independently, enabling multi-tenant usage, workload isolation, and fine-grained resource control. This feature requires PLDM bundle (firmware) 01.25.15.04.

Power management#

AMD GPU Driver 30.20.0 introduces support for Node Power Management (NPM) on AMD Instinct MI355X and MI350X GPUs. This driver-level feature enables centralized control of power distribution across multiple GPUs within a compute node, allowing the system to:

  • Query and set power limits for the entire node.

  • Dynamically redistribute power among GPUs based on workload demands and thermal headroom.

  • Normalize GPU performance by compensating for manufacturing variability across devices.

Resolved issues#

Resolved an issue where the GPU failed to recover after RAS (Reliability, Availability, and Serviceability) poison consumption. The fix applies to all AMD Instinct MI300 and MI350 Series GPUs.
