Subject: [PATCH v6 30/59] perf flamegraph: Port flamegraph to use python module
Date: Sat, 25 Apr 2026 10:48:28 -0700 [thread overview]
Message-ID: <20260425174858.3922152-31-irogers@google.com> (raw)
In-Reply-To: <20260425174858.3922152-1-irogers@google.com>
Add a port of the flamegraph script that uses the perf python module
directly. This approach improves performance by avoiding intermediate
dictionaries for event fields.
Assisted-by: Gemini:gemini-3.1-pro-preview
Signed-off-by: Ian Rogers <irogers@google.com>
---
v5:
1. Fix Event Filtering: Corrected event filtering check to search for a
substring match within the parsed event string, preventing all events
from being dropped due to the `evsel(...)` wrapper.
v6:
- Fixed terminal injection risk by not printing unverified content in
prompt.
