Subject: Re: [PATCH perf-tools-next v9 3/6] perf symbol: Introduce vmlinux_path__find() helper
Date: Wed, 21 Oct 2026 02:45:09 +0000 [thread overview]
Message-ID: <sashiko-outbox-179713@kernel.org> (raw)
In-Reply-To: <20261021023337.809936-4-atomlin@atomlin.com>
> The vmlinux_path array maintains standard paths used by perf to locate
> the kernel image (e.g. "vmlinux", "/boot/vmlinux",
> "/lib/modules/%s/build/vmlinux", "/usr/lib/debug/..."). While
> vmlinux_path__init() populates these candidates and dso__load_vmlinux_path()
> loads symbols into a DSO/map, callers (such as test suites or probing tools)
> often need to verify the existence of an accessible vmlinux on disk before
> attempting machine setup or test execution.
>
> Introduce vmlinux_path__find() to search through the configured vmlinux_path
> entries (or symbol_conf.vmlinux_name if explicitly set) and return the
> path to the first readable vmlinux file, or NULL if none is accessible.
