From ba16021cdbacd425a939167c0928b65abbafb948 Mon Sep 17 00:00:00 2001 From: Michael Chus Date: Sat, 11 Apr 2026 09:59:16 +0300 Subject: [PATCH] Fix GPU model propagation, export filenames, PSU/service status, and chart perf MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - nvidia.go: add Name field to nvidiaGPUInfo, include model name in nvidia-smi query, set dev.Model in enrichPCIeWithNVIDIAData - pages.go: fix duplicate GPU count in validate card summary (4 GPU: 4 x … → 4 x … GPU); fix PSU UNKNOWN fallback from hw.PowerSupplies; treat activating/deactivating/reloading service states as OK in Runtime Health - support_bundle.go: use "150405" time format (no colons) for exFAT compat - sat.go / benchmark.go / platform_stress.go / sat_fan_stress.go: remove .tar.gz archive creation from export dirs — export packs everything itself - charts_svg.go: add min-max downsampling (1400 pt cap) for SVG chart perf - benchmark_report.go / sat.go: normalize GPU fallback to "Unknown GPU" Co-Authored-By: Claude Sonnet 4.6 --- audit/internal/app/support_bundle.go | 2 +- audit/internal/platform/benchmark.go | 6 +- audit/internal/platform/benchmark_report.go | 2 +- audit/internal/platform/platform_stress.go | 8 +- audit/internal/platform/sat.go | 14 +-- audit/internal/platform/sat_fan_stress.go | 6 +- audit/internal/webui/charts_svg.go | 98 ++++++++++++++++ audit/internal/webui/pages.go | 41 ++++++- bible-local/docs/gpu-model-propagation.md | 117 ++++++++++++++++++++ 9 files changed, 263 insertions(+), 31 deletions(-) create mode 100644 bible-local/docs/gpu-model-propagation.md diff --git a/audit/internal/app/support_bundle.go b/audit/internal/app/support_bundle.go index 32a5a2d..7be6e8d 100644 --- a/audit/internal/app/support_bundle.go +++ b/audit/internal/app/support_bundle.go @@ -213,7 +213,7 @@ func BuildSupportBundle(exportDir string) (string, error) { now := time.Now().UTC() date := now.Format("2006-01-02") - tod := now.Format("15:04:05") + tod := now.Format("150405") ver := bundleVersion() model := serverModelForBundle() sn := serverSerialForBundle() diff --git a/audit/internal/platform/benchmark.go b/audit/internal/platform/benchmark.go index d25bde4..059b7c1 100644 --- a/audit/internal/platform/benchmark.go +++ b/audit/internal/platform/benchmark.go @@ -335,11 +335,7 @@ func (s *System) RunNvidiaBenchmark(ctx context.Context, baseDir string, opts Nv return "", fmt.Errorf("write summary.txt: %w", err) } - archive := filepath.Join(baseDir, "gpu-benchmark-"+ts+".tar.gz") - if err := createTarGz(archive, runDir);
