Subject: [PATCHv2] selftests/powerpc: Turn off timeout setting for benchmarks, dscr, signal, tm
Date:   Wed, 18 Mar 2020 14:00:04 +0800
Message-Id: <20200318060004.10685-1-po-hsu.lin@canonical.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Some specific tests in powerpc can take longer than the default 45
seconds that added in commit 852c8cbf34d3 ("selftests/kselftest/runner.sh:
Add 45 second timeout per test") to run, the following test result was
collected across 2 Power8 nodes and 1 Power9 node in our pool:
  powerpc/benchmarks/futex_bench - 52s
  powerpc/dscr/dscr_sysfs_test - 116s
  powerpc/signal/signal_fuzzer - 88s
  powerpc/tm/tm_unavailable_test - 168s
  powerpc/tm/tm-poison - 240s

Thus they will fail with TIMEOUT error. Disable the timeout setting
for these sub-tests to allow them finish properly.
