AMD’s latest firmware updates for Linux include microcode support for Instinct MI350X/MI355X accelerators, RDNA GPUs, and legacy Vega chips. Discover how these updates enhance open-source driver compatibility and performance for high-performance computing.
Key Updates in AMD’s Latest Linux Firmware Release
AMD has upstreamed critical firmware and microcode updates to the linux-firmware.git repository, introducing support for the newly announced AMD Instinct MI350 series accelerators.
These updates ensure seamless functionality with the open-source AMDGPU/AMDKFD Linux compute driver stack.
What’s New in This Release?
MI350 Series Support: First-time inclusion of GC_9_5_0 binaries for Instinct MI350X and MI355X accelerators.
Legacy GPU Updates: Microcode refreshes for Vega 10/Vega 20, RDNA/Navi GPUs, and CDNA-based Instinct accelerators.
IP Discovery Enhancements: New binaries for Vega 10/12/20, Raven/Raven2, Picasso, Aldebaran, and Arcturus GPUs.
These updates are essential for Linux 6.14+ and ROCm 7.0 compatibility, ensuring out-of-the-box support for modern distributions.
Why These Firmware Updates Matter for High-Performance Computing
1. Improved Stability & Bug Fixes
While no detailed changelog is available, these updates typically address minor bugs from Radeon Software driver releases.
The inclusion of IP discovery binaries modernizes driver support for older GPUs, aligning them with AMD’s newer block-by-block enablement approach.
2. Open-Source Driver Support for MI350 Accelerators
The MI350 series marks AMD’s commitment to fully upstreamed open-source Linux support, as highlighted in last week’s announcement. This ensures:
Better compatibility with ROCm for AI/ML workloads.
Optimized performance for data center and HPC environments.
3. Future-Proofing AMD GPU Support on Linux
By extending IP-based discovery to older GPUs, AMD ensures long-term maintainability of its Linux drivers—a shift from monolithic driver models.
How to Access These Updates
To leverage these improvements:
Update linux-firmware packages on your Linux distribution.
Ensure Linux kernel 6.14+ and ROCm 7.0 for full MI350 support.
Monitor official repositories for stable release rollouts.
Frequently Asked Questions (FAQ)
Q: Do these updates affect gaming performance on RDNA GPUs?
