Subject: Re: [PATCH 1/2] perf tests: Skip zero sample IP in object-code reading test
Date: Fri, 06 Nov 2026 07:41:43 +0000 [thread overview]
Message-ID: <sashiko-outbox-201001@kernel.org> (raw)
In-Reply-To: <20261106073018.903126-1-dapeng1.mi@linux.intel.com>
> The kernel may clear the sample IP to 0 when a user-space address is
> expected but a kernel address is sampled due to hardware skid. A zero
> sample IP causes the object-code reading test to fail incorrectly.
>
> Skip zero sample IP values in the object-code reading test to avoid
> false-positive failures.
>
> Reported-by: kernel test robot <yi1.lai@intel.com>
> Closes: https://lore.kernel.org/oe-lkp/202609151503.cb02f753-lkp@intel.com
> Fixes: 166f10836a65 ("perf/core: Fix kernel register info leak via hardware skid")
