Added NVIDIA RTX Spark N1X and native Windows ARM64 support with DLA metrics on the GPU row, read the N1X DLA engine clock, and fixed false 100% Intel Xe utilization from frozen GT idle counters.

all-smi v0.28.0

4 commits since v0.27.1. (3381 lines added, 261 lines deleted)

New Features

  • Added NVIDIA RTX Spark N1X support: the integrated NPU folds into the SoC GPU row as a DLA gauge and sparkline instead of a separate device, and the GPU reports unified memory over NVLink-C2C without PCIe gauges (#460).
  • Added native Windows ARM64 (aarch64-pc-windows-msvc) builds and the all-smi-windows-aarch64 release asset (#460).
  • Added all_smi_dla_power_watts, all_smi_dla_frequency_mhz, all_smi_dla_clock_memory_mhz, all_smi_dla_temperature_celsius, and all_smi_dla_max_frequency_mhz Prometheus gauges, read back by remote view (#460, #462).
  • Added the N1X DLA engine clock, read from D3DKMT node performance data because NVML reports it as unsupported (#462).

Improvements

  • Added Windows ARM CPU detection with P/E core mapping (Cortex-X925/A725) and a registry processor-name fallback (#460).
  • Added Windows thermal-zone performance counters as a last-resort CPU temperature source after the vendor sensors (#460).
  • Filled WDDM per-process GPU memory from PDH samples when NVML reports it unavailable (#460).
  • Stopped polling NVML DLA clock types that answer NotSupported after the first probe (#462).

Bug Fixes

  • Fixed constant false 100% Intel Xe GPU utilization when a GT idle-residency counter never advances; such GTs now read as stalled (#458).
  • Fixed the nvidia-smi CSV fallback dividing power draw by 1000 (#460).
  • Stopped retrying the root\WMI temperature query every poll after an access-denied error (#460).

CI/CD Improvements

  • Added a windows-11-arm CI job running clippy, library tests, and a release build (#460).
  • Added all-smi-windows-aarch64 to the release matrix, with a composite action that puts LLVM/clang on PATH (#460).
  • Signed the Windows ARM64 binary on the x86_64 signing runner; the all-smi-windows-aarch64 asset was rebuilt and replaced with an Authenticode-signed binary after publication (#464).

Technical Details

  • The DLA engine clock is read before the poll's NVML queries reach the NPU, because those queries briefly raise it to about 1105 MHz (#462).
  • D3DKMTEnumAdapters3 is resolved from gdi32.dll at run time so the binary still starts on older Windows 10 (#462).
  • Enabled the Wdk_Graphics_Direct3D, Win32_System_Registry, and Win32_System_SystemInformation features of the windows crate (#460, #462).

Dependencies

None

Breaking Changes

  • Building from source on Windows ARM64 requires LLVM with clang on PATH, because ring and aws-lc-sys cannot build there with MSVC alone (#460).

Known Issues

  • Tags created before v0.28.0 cannot rebuild the Windows ARM64 target through the release self-healing path.

What's Changed

  • fix: ignore frozen Xe GT idle counters in utilization fallback by @inureyes in #458
  • feat: add NVIDIA RTX Spark N1X and Windows ARM64 support by @inureyes in #460
  • feat: read N1X DLA engine clock from D3DKMT node perf data by @inureyes in #462
