Motivation

This PR applies per-agent scoping from PR #9868 to the thread-trace callback-removal branch.

Technical Details

• Per-agent serialization ref-counting in queue_controller
• DispatchThreadTracer configured_agents/collects_on/intersects helpers
• Scoped enable/disable serialization in start_context/stop_context
• Agent filtering in thread_trace::write_hook
• Disjoint dispatch ATT context conflict rules

Automated stacked-PR status check (Cursor)

This PR's base branch (users/vkale/remove-callbacks-thread-trace-cursor-fixes) has no open tracking PR — it looks like it was pushed directly rather than opened as a PR (unlike the counters/SPM "cursor-fixes" pattern used elsewhere in this stack family). Under the "base PR must also be yours" merge policy, there's currently no base PR to evaluate readiness against, so this can't be considered for stacked auto-merge as-is.

Other blockers:

• Still marked draft.
• CI is failing: Code Coverage, Core (sles-15.6, ubuntu-22.04), the rocprofiler-sdk test job, and TheRock CI Summary.
• The root of this stack (refactor(rocprofiler-sdk): migrate thread trace off the per-queue callback registry #8790) is ~1506 commits behind current develop, and its head branch lives in your fork (amd-vkale/rocm-systems) rather than upstream, unlike the other two stacks — worth reconciling for consistency.
• Static analysis (CodeQL) fails on refactor(rocprofiler-sdk): migrate thread trace off the per-queue callback registry #8790 with what looks like the same repo-wide workflow-template parse error seen elsewhere in this stack family.

Remaining steps:

1. Open a tracking PR for users/vkale/remove-callbacks-thread-trace-cursor-fixes (or fold it into refactor(rocprofiler-sdk): migrate thread trace off the per-queue callback registry #8790) so there's an actual base PR to gate on.
2. Take this PR out of draft once ready.
3. Fix the failing CI jobs.
4. Rebase the whole thread-trace stack onto current develop (1506 commits behind).

Mergeability (local review + GPU unit tests, 2026-08-18)

This draft is not ready to fold into #8790.

• Still a draft, zero reviews.
• Per-agent ATT scoping is a feature, not a review-fix.

Separately: this PR is based on users/vkale/remove-callbacks-thread-trace-cursor-fixes, which has no pull request. That one commit (cc09f3c053 — reject a second concurrent ATT context, drop the dead client global) is ready to land in #8790. It is exactly the fast-follow @bwelton asked for when approving #8790. Local thread-trace-queue-hooks-test (1/1) and thread-trace-packet-test (8/8) passed on that tip.

Plan: fast-forward that unpublished commit into #8790, then retarget this draft onto #8790. Do not merge this draft with #8790.

[amd-vkale]

Update: the unpublished thread-trace cursor-fixes commit is now in #8790 (cc09f3c053). This PR’s base was retargeted onto users/vkale/remove-callbacks-thread-trace. Still draft / not for fold.

[amd-vkale]

Folded into #8790. Dispatch ATT per-agent scoping is now on users/vkale/remove-callbacks-thread-trace (d39785f333), plus new unit tests for disjoint vs overlapping contexts, scoped serialization, and write_hook skipping other agents. GitHub marked this PR merged once the base fast-forwarded through the feature commits.
