[2026-03-27] AMDGPU Driver For Linux 7.1 Preps Debug Improvements, New Hardware IP

Source: Phoronix (AMD Linux)

Key takeaway relevant to AMD:

  • Proactive enablement of upcoming hardware blocks ensures Day-1 compatibility for next-generation AMD products on Linux, while fixes to non-x86_64 architectures ensure AMD hardware operates flawlessly on ARM or RISC-V workstation host systems.

Summary:

  • The final pull requests for AMDGPU and AMDKFD kernel graphics drivers are queuing up ahead of the Linux 7.1 merge window.
  • The update brings support for new System Management Unit (SMU) and Display Core Next (DCN) IP, alongside various memory and queue priority fixes.

Details:

  • New Hardware IP: Introduces support for SMU 15.0.8 and DCN (Display Core Next) 4.2.
  • New Features: Adds a new DebugFS interface specifically for monitoring 64-bit PCIe registers.
  • Key Fixes: Resolves GPU page faults for non-4K page size kernel builds (critical for environments outside of standard x86_64 architecture). Fixes graphics queue priorities, user queue (“UserQ”), DSC, PASID reuse, and minor SMU 13.x/14.x/15.x bugs.
  • Implications for Developers/Users: Users building custom enterprise Linux environments (especially on alternative ISAs with non-4K memory pages) will experience better AMDGPU stability. Developers get enhanced debugging tools via the new PCIe64 DebugFS interface.

🤼‍♂️ Market & Competitors

[2026-03-27] Testing DirectStorage with GPU decompression — do Blackwell GPUs have the upper hand?

Source: Tom’s Hardware (GPUs)

Key takeaway relevant to AMD:

  • AMD Radeon GPUs have historically processed DirectStorage GPU decompression without performance penalties. NVIDIA has finally resolved their specific architectural bottleneck in this area with the Blackwell generation, removing an isolated competitive advantage for AMD in high-end asset streaming.

Summary:

  • Tom’s Hardware benchmarked Microsoft DirectStorage 1.1 GPU decompression (using GDeflate) on NVIDIA’s new RTX 50-series (Blackwell) against the previous RTX 40-series.
  • Unlike Ada Lovelace cards, Blackwell GPUs handle simultaneous rendering and decompression flawlessly, catching up to the baseline stability established by AMD Radeon GPUs.

Details:

  • Historical Context: Previous tests on RTX 4090/4060 GPUs showed up to an 18-25% drop in 1% low frame rates in titles like Spider-Man 2 when GPU decompression was active. AMD Radeon GPUs never exhibited this flaw.
  • Blackwell Benchmarks: RTX 5090, 5070, and 5060 GPUs showed zero performance degradation. The 5060 maintained steady 1% lows even at 98% GPU utilization at 1080p.
  • Architectural Changes (Speculative): Blackwell features a new AI Management Processor (AMP) utilizing a dedicated RISC-V core designed specifically to optimize Windows Hardware-Accelerated GPU Scheduling (HAGS). This allows superior asynchronous workload scheduling compared to the 40-series.
  • Implications for Developers/Users: Game developers utilizing DirectStorage can now confidently target GPU decompression on modern hardware from both major vendors without needing fallback paths for NVIDIA users, standardizing fast asset streaming requirements.

[2026-03-27] Linux Patches Posted To Fix ~2x Performance Drop For CPU Workloads On NVIDIA Vera Rubin

Source: Phoronix (AMD Linux)

Key takeaway relevant to AMD:

  • NVIDIA’s foray into custom data center CPUs is experiencing growing pains with Linux standard task schedulers. AMD’s long-standing EPYC maturity provides a massive reliability edge for enterprise clients deploying complex SMT workloads.

Summary:

  • NVIDIA engineers have posted Linux v7.1 scheduler patches to resolve massive performance regressions on their upcoming Vera Rubin platform.
  • The patches improve the Linux kernel’s Simultaneous Multi-Threading (SMT)-aware asymmetric CPU capacity scheduling.

Details:

  • The Issue: Vera firmware exposes minor frequency variations (+/- 5%) as CPU capacity differences (SD_ASYM_CPUCAPACITY). The standard Linux idle selection policy failed to account for busy SMT siblings, leading to a ~50% (~2x) performance drop in CPU-intensive tasks.
  • The Fix: Patches instruct the scheduler to prioritize fully-idle cores over partially-idle SMT siblings when SMT is active.
  • Implications for Developers/Users: System administrators and enterprise developers evaluating NVIDIA Vera CPUs will need to ensure they are operating on Linux 7.1+ kernels or backported environments to avoid severe compute bottlenecks that do not exist on mature AMD EPYC deployments.

[2026-03-27] KDE Plasma 6.6 Showing Frequent Performance Advantage Over GNOME 50 With NVIDIA R595 Driver

Source: Phoronix (AMD Linux)

Key takeaway relevant to AMD:

  • While KDE Plasma continues to showcase performance optimizations beneficial to all GPUs, AMD’s open-source driver stack remains vastly superior in stability on Linux desktop environments compared to NVIDIA’s proprietary R595 stack.

Summary:

  • Phoronix benchmarked KDE Plasma 6.6.3 versus GNOME 50.0 on Ubuntu 26.04 beta using an NVIDIA RTX 5080.
  • Results validated previous AMD Radeon tests, showing KDE Plasma generally provides superior performance over GNOME.

Details:

  • Software Stack: Tested on Ubuntu 26.04 beta with NVIDIA 595.58.03 proprietary Linux graphics drivers.
  • Stability Discrepancy: The benchmark was restricted to the Wayland session only. Attempting to log into an X11 session using the NVIDIA 595.58.03 driver resulted in an immediate crash upon startup. In previous testing, AMD Radeon hardware successfully completed benchmarks across both X11 and Wayland sessions flawlessly.
  • Implications for Developers/Users: Linux users utilizing legacy applications reliant on X11 will find a heavily degraded/broken experience on NVIDIA Blackwell hardware, making AMD Radeon the fundamentally safer choice for flexible Linux desktop setups.
