[BUG] "Day Zero" Gemma 4 support missing for Linux (Strix Halo/XDNA 2) on lemond 10.2.0

[barneysspeedshop]

Hardware / Environment:

• CPU: AMD Ryzen AI MAX+ 395 (Strix Halo)
  

• NPU: XDNA 2 (50 TOPS)
  

• OS: Linux (Mint/Ubuntu-based)
  

• Kernel: [7.0.0]
  

• Driver: amdxdna (DKMS/In-tree)
  

• Lemonade Version: 10.2.0
  

Despite official marketing claiming "Day Zero" support for Google's Gemma 4 family on Ryzen AI processors, the current public-facing stack for Linux is non-functional for Strix Halo (STX-H) users.

Observed Behavior:

• Catalog Mismatch: The lemonade catalog does not list the official Gemma 4 E2B/E4B NPU recipes. The only available entry is Gemma4-it-e2b-FLM, which appears to be a legacy FastFlowLM container.
  

• Hang on Load: Attempting to run Gemma4-it-e2b-FLM results in an indefinite hang or a silent fallback to CPU.
  

• SDK Version Gap: The "Official AMD Portal" is currently serving Ryzen AI Software v1.7.1, which predates the Gemma 4 release. The required firmware and AIE tiling metadata for Gemma 4 (likely v1.7.2+) are missing from the public distribution.
  

• Incompatible Firmware/Driver: Verification via flm validate or checking /sys/class/accel/ shows that while the hardware is present, the protocol versioning in the 1.7.1 stack does not support the MoE or hybrid-attention layers in the Gemma 4 architecture.
  

Steps to Reproduce:

• Run lemond catalog on a Strix Halo Linux machine.
  

• Observe the absence of amd/Gemma-4-E2B-Instruct-GGUF.
  

• Attempt to pull/run the existing FLM variant.
  

• Server hangs during model initialization.
  

Suggested Fix / Ask:

• Synchronize the public Hugging Face / Lemonade recipes with the internal "Day Zero" builds.
  

• Provide a clear path for Linux users to update to the 1.7.2 firmware/driver matching the Gemma 4 release.
  

• Fix the unsupported-sku check for Strix Halo in the amdxdna user-space tools.
