[2026-01-19] New Patches Provide HDMI VRR & Auto Low Latency Mode Gaming Features For AMD Linux GPU Driver

Source: Phoronix

Key takeaway relevant to AMD:

  • Bypasses long-standing HDMI Forum restrictions that prevented open-source drivers from implementing HDMI 2.1 features.
  • Significantly improves the Linux gaming experience for AMD users connecting to modern TVs/monitors via HDMI.

Summary:

  • Developer Tomasz Pakuła submitted a patch series enabling HDMI Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM) for AMDGPU.
  • The implementation relies on public knowledge and trial-and-error rather than official HDMI Forum specifications, which are closed to open-source drivers.

Details:

  • Features Enabled:
    • HDMI VRR: Enables FreeSync/VRR over HDMI (previously limited to DisplayPort).
    • Auto Low Latency Mode (ALLM): An HDMI 2.1 feature that switches displays to “Game Mode” to reduce input lag.
  • Technical Implementation:
    • Detects if AMD vendor-specific data blocks (vsdb) carry wider VRR ranges.
    • Reintroduces proper HF-VSIF and VTEM info packets.
    • DP-to-HDMI PCON changes, including a module property to override PCON ID checks.
    • Fixes VRR detection failures when monitors use GTF flags instead of Range Limits Only.
  • Implications: This is a community-led effort “outside of AMD” to resolve a legal/licensing blockage, potentially risking conflict with the HDMI Forum, but solving a major feature gap for Linux users.

[2026-01-19] RADV Vulkan Driver Now Implements HPLOC For Even Faster Ray-Tracing Performance

Source: Phoronix

Key takeaway relevant to AMD:

  • Immediate performance uplift for Ray Tracing workloads on AMD hardware running Linux (Mesa/RADV).
  • Demonstrates the value of Valve’s continued investment in the AMD Linux graphics stack.

Summary:

  • Support for HPLOC (Hierarchical Parallel Locally-Ordered Clustering) has been merged into the RADV driver for the upcoming Mesa 26.0 release.
  • The update optimizes Bounding Volume Hierarchy (BVH) construction.

Details:

  • Performance Metrics:
    • Cyberpunk 2077: ~5% performance improvement.
    • General Uplift: Other titles show 2-3% improvements.
    • Frame Time: Saves approximately ~1ms of frame time during Top-Level Acceleration Structure (TLAS) builds.
  • Technology: HPLOC is a faster algorithm for constructing BVHs compared to the existing PLOC usage, maintaining comparable BVH quality while reducing build times.
  • Timeline: Merged for Mesa 26.0 (Stable release expected in February 2026).

[2026-01-19] New Patches From Valve Bring AMDGPU Power Management Improvements For Old GCN 1.0 GPUs

Source: Phoronix

Key takeaway relevant to AMD:

  • Refines driver stability and performance for legacy “Southern Islands” (GCN 1.0) hardware, ensuring these 14-year-old cards remain viable on modern Linux kernels.

Summary:

  • Valve contractor Timur Kristóf posted patches for GCN 1.0 power management on the modern AMDGPU kernel driver.
  • The primary focus is fixing buggy power tuning that prevented specific GPUs from reaching advertised clock speeds.

Details:

  • Target Hardware: GCN 1.0 (Southern Islands) and GCN 1.1 (Sea Islands), specifically the Radeon R5 430.
  • The Bug: The R5 430 “powertune” implementation was throttling the GPU, preventing it from reaching maximum SCLK.
  • The Fix:
    • Raised TDP limits programmed to the SMC from 24W (VBIOS default) to 32W.
    • Revised maximum SCLK limit to 780 MHz.
    • Note on Radeon 520: While VBIOS claims 905 MHz support, the patch avoids this as it causes overheating (>100°C) without performance gains.
  • Code Changes: Better handling of power2_cap when power limits cannot be read, and avoidance of unnecessary power limit recalculations.
