Subject: Re: [PATCH 1/6] perf jevents: Process model files before sys subdirectories
Date: Mon, 19 Oct 2026 16:47:49 +0000 [thread overview]
Message-ID: <sashiko-outbox-177936@kernel.org> (raw)
In-Reply-To: <20261019164241.403644-2-bwicaksono@nvidia.com>
> jevents walks each directory in name order, mixing files and
> subdirectories. When it reaches a sys/ directory inside a model
> directory, process_one_file() flushes the model's pending tables and
> switches the pending table name to the sys table. After the walk
> returns from sys/, nothing switches it back, so model JSON files whose
> names sort after "sys" (for example tlb.json) are added to the sys
> table. Sys tables are only matched by Compat against uncore PMU
> identifiers, so these core events are lost: perf list doesn't show
> them and perf stat rejects them.
>
> Visit the files of a directory before its subdirectories, so that all
> of a model's JSON files are added to the model's table before a sys/
> subdirectory is processed. The generated pmu-events.c is unchanged for
> the existing event directories.
