The session topology test fails in powerpc pSeries platform.Test logs:<<>>Session topology : FAILED!<<>> This test uses cpu topology information and in powerpc,some of the topology info is restricted in environmentlike virtualized platform. Hence this test needs to beskipped in pSeries platform for powerpc. The informationabout platform is available in /proc/cpuinfo. Patch 1 adds generic utility function in "util/header.c"to read /proc/cpuinfo for any entry. Though the testcasefix needs value from "platform" entry, making this as ageneric function to return value for any entry from the/proc/cpuinfo file which can be used commonly in futureusecases. Patch 2 uses the newly added utility function to look forplatform and skip the test in pSeries platform for powerpc. Athira Rajeev (2): tools/perf: Add utility function to read /proc/cpuinfo for any field tools/perf/tests: Fix session topology test to skip the test in guest environment Changelog: V1 -> v2: Addressed review comments from Kajol. Use "strim" to remove space from string. Also use "feof" to check for EOF instead of using new variable "ret". Tested the patches on powervm and powernv, verified perf test session topology test with the patch set.Tested-by: Disha Goel < disg...@linux.vnet.ibm.com> tools/perf/tests/topology.c | 17 ++++++++++++ tools/perf/util/header.c | 53 +++++++++++++++++++++++++++++++++++++ tools/perf/util/header.h | 1 + 3 files changed, 71 insertions(+)
