Subject: Re: [RFC PATCH v2 1/9] perf pmu: Add from_env parameter to perf_pmu__init()
Date: Sat, 17 Oct 2026 19:06:36 +0000 [thread overview]
Message-ID: <sashiko-outbox-175771@kernel.org> (raw)
In-Reply-To: <20261017185442.2137623-2-irogers@google.com>
> Add a boolean from_env field to struct perf_pmu initialized via
> perf_pmu__init() to distinguish PMUs reconstructed from perf_env
> headers from live host PMUs. Guard tp_pmu, hwmon_pmu, and drm_pmu
> callbacks on !pmu->from_env so perf.data-derived PMUs do not access
> host tracepoints or cast plain struct perf_pmu allocations via
> container_of().
