2024-02-05perf/pmu-events/powerpc: Update json mapfile with Power11 PVRMadhavan Srinivasan1-0/+1
Update the Power11 PVR to json mapfile to enable json events. Power11 is PowerISA v3.1 compliant and support Power10 events.

2023-12-21perf vendor events powerpc: Add PVN for HX-C2000 CPU with Power8 ArchitectureJiaLong.Yang1-2/+1
HX-C2000 is a new CPU made by HEXIN Technologies Co., Ltd. And a new PVN 0x0066 has been applied from the OpenPower Community for this CPU. Here is a patch to make perf tool run in the CPU.

2023-10-17tools/perf/arch/powerpc: Fix the CPU ID const char* value by adding 0x prefixAthira Rajeev1-3/+3
Simple expression parser test fails in powerpc as below: 4: Simple expression parser test child forked, pid 170385 Using CPUID 004e2102 division by zero syntax error syntax error FAILED tests/expr.c:65 parse test failed test child finished with -1 Simple expression parser: FAILED! This is observed after commit: 'commit 9d5da30e4ae9 ("perf jevents: Add a new expression builtin strcmp_cpuid_str()")' With this commit, a new expression builtin strcmp_cpuid_str got added. This function takes an 'ID' type value, which is a string. So expression parse for strcmp_cpuid_str expects const char * as cpuid value type. In case of powerpc, CPU IDs are numbers. Hence it doesn't get interpreted correctly by bison parser. Example in case of power9, cpuid string returns as: 004e2102 cpuid of string type is expected in two cases: 1. char *get_cpuid_str(struct perf_pmu *pmu __maybe_unused); Testcase "tests/expr.c" uses "perf_pmu__getcpuid" which calls get_cpuid_str to get the cpuid string. 2. cpuid field in :struct pmu_events_map struct pmu_events_map { const char *arch; const char *cpuid; Here cpuid field is used in "perf_pmu__find_events_table" function as "strcmp_cpuid_str(map->cpuid, cpuid)". The value for cpuid field is picked from mapfile.csv. Fix the mapfile.csv and get_cpuid_str function to prefix cpuid with 0x so that it gets correctly interpreted by the bison parser Signed-off-by: Athira Rajeev <atrajeev@linux.vnet.ibm.com> Tested-by: Disha Goel<disgoel@linux.ibm.com> Cc: kjain@linux.ibm.com Cc: maddy@linux.ibm.com Cc: disgoel@linux.vnet.ibm.com Cc: linuxppc-dev@lists.ozlabs.org Link: https://lore.kernel.org/r/20231009050052.64935-1-atrajeev@linux.vnet.ibm.com Signed-off-by: Namhyung Kim <namhyung@kernel.org>

2017-12-05perf vendor events: Use more flexible pattern matching for CPU ↵William Cohen1-10/+2
identification for mapfile.csv The powerpc cpuid information includes chip revision information. Changes between chip revisions are usually minor bug fixes and usually do not affect the operation of the performance monitoring hardware. The original mapfile.csv matching requires enumerating every possible cpuid string. When a new minor chip revision is produced a new entry has to be added to the mapfile.csv and the code recompiled to allow perf to have the implementation specific perf events for this new minor revision. For users of various distibutions of Linux having to wait for a new release of the kernel's perf tool to be built with these trivial patches is inconvenient. Using regular expressions rather than exactly string matching of the entire cpuid string allows developers to write mapfile.csv files that do not require patches and recompiles for each of these minor version changes. If special cases need to be made for some particular versions, they can be placed earlier in the mapfile.csv file before the more general matches.

2017-08-11perf vendor events powerpc: remove suffix in mapfileSukadev Bhattiprolu1-10/+10
Drop the .json suffix for events directory in the mapfile.csv. Now that we have separate JSON files for each topic in a CPU (eg: see tools/perf/pmu-events/arch/powerpc/power8/*.json) the .json suffix in the mapfile is misleading and redundant.
