Subject: [PATCH 0/2] perf tests: Check for ARM [vectors] page
Date: Wed, 24 Oct 2018 17:09:03 -0700 [thread overview]
Message-ID: <20181025000905.6095-1-f.fainelli@gmail.com> (raw)
Hi all,
I just painfully learned that perf would segfault when
CONFIG_KUSER_HELPERS is disabled because it unconditionally makes use of
it. This patch series adds an ARM test for that by leveraging the
existing find_vdso_map() function and making it more generic and capable
of location any map within /proc/self/maps.
Florian Fainelli (2):
perf tools: Make find_vdso_map() more modular
perf tests: Add a test for the ARM 32-bit [vectors] page
