perf tests stat+json_output: Include sanity check for topology
Testcase stat+json_output.sh fails in powerpc:
86: perf stat JSON output linter : FAILED!
The testcase "stat+json_output.sh" verifies perf stat JSON output. The test covers aggregation modes like per-socket, per-core, per-die, -A (no_aggr mode) along with few other tests. It counts expected fields for various commands. For example say -A (i.e, AGGR_NONE mode), expects 7 fields in the output having "CPU" as first field. Same way, for per-socket, it expects the first field in result to point to socket id. The testcases compares the result with expected count.
The values for socket, die, core and cpu are fetched from topology directory:
/sys/devices/system/cpu/cpu*/topology.
For example, socket value is fetched from "physical_package_id" file of topology directory. (cpu__get_topology_int() in util/cpumap.c)
If a platform fails to fetch the topology information, values will be set to -1. For example, incase of pSeries platform of powerpc, value for "physical_package_id" is restricted and not exposed. So, -1 will be assigned.
Perf code has a checks for valid cpu id in "aggr_printout" (stat-display.c), which displays the fields. So, in cases where topology values not exposed, first field of the output displaying will be empty. This cause the testcase to fail, as it counts number of fields in the output.
Incase of -A (AGGR_NONE mode,), testcase expects 7 fields in the output, becos of -1 value obtained from topology files for some, only 6 fields are printed. Hence a testcase failure reported due to mismatch in number of fields in the output.
Patch here adds a sanity check in the testcase for topology. Check will help to skip the test if -1 value found.
