Feat/cross-vendor GPU metrics to sysinfo plots - #3507
Conversation
Extend the sysinfo GPU collector beyond NVIDIA by keeping the nvidia-smi path and adding AMD collection through amd-smi, with rocm-smi as a fallback for older ROCm installations. Keep command execution constrained to fixed binary names and arguments, reuse the same timeout/output cap for each GPU query, and strictly validate utilization and memory values before publishing time-series metrics. Normalize discovered GPU indices before publishing so mixed vendor systems expose stable gpu:N and gpumem:N:* keys, and update the sysinfo plot menu copy to describe installed GPU tools rather than NVIDIA only. Add parser tests for AMD SMI monitor output, ROCm SMI JSON output, and GPU index normalization.

WalkthroughThe change adds cross-platform GPU telemetry for NVIDIA, AMD, ROCm, macOS, and Intel systems. It validates, normalizes, aggregates, and publishes GPU utilization and memory metrics. Sysinfo plots now support dynamic metric discovery, persisted metric selections, per-core and per-GPU metrics, and legacy plot fallback. Preview data and tests now include GPU metrics. Priority: ➖ Normal Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🔵 Low · up to Per-GPU memory telemetry is collected but users cannot add those plots through the Sysinfo menu. Address this small feature gap before merge if per-device memory selection is part of the intended release. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

On multi-GPU or mixed-vendor systems, if an earlier device is omitted for one poll because its command fails or its row is rejected, assigning indices from the current slice position renames every later device. For example, physical GPU 1 changes from gpu:1 to gpu:0 whenever GPU 0 is missing, merging unrelated utilization values into the same time series and corrupting per-device plots. Keep a stable vendor/device identity rather than compacting each individual sample set.

When an ioreg entry lacks the preferred device-utilization keys and reports only fallback fields such as Renderer Utilization % or Tiler Utilization %, a valid idle reading has a sum of zero and is treated as absent here. Consequently an idle Intel/macOS GPU disappears from the sample entirely and only reappears once it becomes busy; track whether any valid fallback field was found separately from its numeric sum.

Inline comments:
In `@frontend/app/view/sysinfo/sysinfo.tsx`:
- Around line 140-146: Update the GPU menu item's getMetrics function to inspect
the provided DataItem and return ["gpu"] only when its gpu value is available;
otherwise return an empty array. Match the availability check used by the
existing All GPUs menu contract and preserve the current behavior when GPU data
exists.
In `@pkg/wshrpc/wshremote/sysinfo.go`:
- Around line 684-691: Update getGpuData and the RunSysInfoLoop collection flow
to avoid invoking every GPU collector serially on each tick. Cache the first
working collector and reuse its samples, retrying collector detection only after
the cached collector fails; alternatively, reuse the latest GPU value between
less frequent probes. Ensure the total sysinfo collection remains bounded so GPU
probing cannot create gaps exceeding the loop’s timing expectations.
- Around line 492-499: Update normalizeGpuSamples and its collector call sites
to preserve each sample’s source collector identity when assigning indices. Use
the fixed collector order and encode each nonnegative local parser index with
its source index and total collector count, allowing sparse numeric keys and
preventing collisions when collectors return different sample counts.
- Around line 433-490: Update parseIntelGpuTopSampleUtil to derive whole-GPU
utilization from the sample’s rc6.value as 100 minus that value, rather than
summing engines.*.busy values; validate the value and preserve the existing
unavailable-sample behavior when rc6 is absent or invalid. Add the rc6 field to
intelGpuTopSample using the JSON shape emitted by intel_gpu_top, and retain an
appropriate fallback for samples without usable rc6 data.
