From b5a646a681f5d67ea5190a71d6e84a91efe63b7a Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 13 Aug 2020 11:34:45 +1000 Subject: [PATCH] selftests/powerpc: Run tm-tmspr test for longer This test creates some threads, which write to TM SPRs, and then makes sure the registers maintain the correct values across context switches and contention with other threads. But currently the test finishes almost instantaneously, which reduces the chance of it hitting an interesting condition. So increase the number of loops, so it runs a bit longer, though still less than 2s on a Power8.
