Merge main-next to main by umanwizard · Pull Request #226 · parca-dev/opentelemetry-ebpf-profiler

umanwizard · 2026-03-05T22:52:03Z

This rebases the delta in our fork of opentelemetry-ebpf-profiler on top of upstream main. It will eventually become our main once we let it bake for a while to gain confidence in its correctness.

This PR replaces #209, which had the draft branch name btv/merges.

In order to reduce bpf overhead send through up to 128 kernel launch timing activities to the usdt probe. The old single shot kernel_executed probe is still supported. Inline correlation and kernel_exec into cuda_probe, tail-call only activity_batch The unwinder is sensitive to tail calls, so minimize them: inline cuda_correlation and cuda_kernel_exec directly into cuda_probe's switch statement using bpf_usdt_arg() for USDT arg reading.

* Uncomment GPU tests Just uncomment the tests that were commented out in 42fef97. These don't compile yet due to API changes. * Update GPU tests for current APIs - Rewrite eBPF-level hash tests (computeTraceHash/makeCUDATrace) to use libpf.Trace + traceutil.HashTrace since support.Frame/Stack_len/ ZeroPerSampleFields no longer exist - Replace Frame.FileID with Frame.Mapping (FrameMapping) - Update CustomLabels access: string keys → libpf.String (libpf.Intern) - Drop TestCUDATraceHashExcludesPerSampleFields (per-sample fields now live in TraceEventMeta, not libpf.Trace, so they never affect hash) - Remove unused imports (host, xxh3, unsafe) * Move interceptor logic into gpu package, avoid allocations, add finishTrace callback Pass a finishTrace callback through TraceInterceptor so the gpu package can report completed traces directly. Move CUDA frame scanning and ID extraction from parcagpu into gpu.InterceptTrace, making the parcagpu interceptor a thin origin check + delegation. Split addTrace into addSingleTrace and addGraphTrace: - addSingleTrace returns a single (CudaTraceOutput, bool) on the stack — no slice allocation, no SymbolizedCudaTrace when timing already arrived. - addGraphTrace returns []CudaTraceOutput and always stores for future timing events. InterceptTrace dispatches based on isGraphLaunch and calls finishTrace outside the fixer lock. Move HashTrace out of prepTrace. Each reporting path hashes once at the point of reporting: finishTrace for intercepted traces, inline for the normal HandleTrace path, and processBatch for the AddTimes path. finishTrace does not call maybeNotifyAPMAgent: intercepted traces may also be completed on a different path that lacks bpfTrace context for APM notification, so we skip it for consistency. * Review fixes * one more * simplify tests

Not sure why CI isn't running here.

This reverts commit 47f0ca7.
