Subject: Re: [PATCH 01/15] perf debuginfo: Fetch debuginfo keyed by build ID using debuginfod
Date: Thu, 17 Sep 2026 16:03:54 +0000 [thread overview]
Message-ID: <20260917160354.B247E1F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20260917155528.62607-2-acme@kernel.org>
> From: Arnaldo Carvalho de Melo <acme@redhat.com>
>
> Add debuginfo__find_build_id(), which uses the debuginfod client to
> locate a debuginfo file keyed by the build ID - checking its local cache
> first and then the servers in DEBUGINFOD_URLS - and
> debuginfo__new_build_id(), which opens the DWARF in the file it finds.
> dso__debuginfo() falls back to it for DSOs whose debuginfo is not
> installed locally, e.g. the vmlinux of a kernel profiled on another
> machine or upgraded since, doing the fetch outside dso__lock.
>
> Querying servers, possibly third party ones, sends the build IDs of the
> binaries being analysed off-box, and a fetch can take a while, so this
> is opt-out: --no-debuginfod, core.debuginfod=false,
> report.debuginfod/top.debuginfod, and off also when the build-id cache
> is disabled. Fetches are serialized and misses are remembered, as both
> the lookup state and the fetch interaction are process global.
