perf test: Add test case for pmu event new style format Add test case in automated tests suite. It checks not only the two types of pmu event stytle formats "pmu_event_name" and "cpu/pmu_event_name/", but also the different formats mixtures which are more likely to trigger parse issue. The patch set including this one has been tested by the perf automated test: ./perf test parse -v" On haswell, ivybridge and Romley platform. The patch set also has been tested on haswell by the following script. Note: please make sure that your test system support TSX and L1-dcache-loads events. Otherwise, you may want to change the events to other pmu events.

perf tools: Use __maybe_used for unused variables perf defines both __used and __unused variables to use for marking unused variables. The variable __used is defined to __attribute__((__unused__)), which contradicts the kernel definition to __attribute__((__used__)) for new gcc versions. On Android, __used is also defined in system headers and this leads to warnings like: warning: '__used__' attribute ignored __unused is not defined in the kernel and is not a standard definition. If __unused is included everywhere instead of __used, this leads to conflicts with glibc headers, since glibc has a variables with this name in its headers. The best approach is to use __maybe_unused, the definition used in the kernel for __attribute__((unused)). In this way there is only one definition in perf sources (instead of 2 definitions that point to the same thing: __used and __unused) and it works on both Linux and Android. This patch simply replaces all instances of __used and __unused with __maybe_unused.

perf tools: Add parse_events_error interface Adding support to return error information from parse_events function. Following struct will be populated by parse_events function on return: struct parse_events_error { int idx; char *str; char *help; }; where 'idx' is the position in the string where the parsing failed, 'str' contains dynamically allocated error string describing the error and 'help' is optional help string. The change contains reporting function, which currently does not display anything. The code changes to supply error data for specific event types are coming in next patches. However this is what the expected output is: $ sudo perf record -e 'sched:krava' ls event syntax error: 'sched:krava' \___ unknown tracepoint ... $ perf record -e 'cpu/even=0x1/' ls event syntax error: 'cpu/even=0x1/' \___ unknown term valid terms: pc,any,inv,edge,cmask,event,in_tx,ldlat,umask,in_tx_cp,offcore_rsp,config,config1,config2,name,period,branch_type ... $ perf record -e cycles,cache-mises ls event syntax error: '..es,cache-mises' \___ parser error ... The output functions cut the beginning of the event string so the error starts up to 10th character and cut the end of the string of it crosses the terminal width.

perf test: Add test case for pmu event new style format Add test case in automated tests suite. It checks not only the two types of pmu event stytle formats "pmu_event_name" and "cpu/pmu_event_name/", but also the different formats mixtures which are more likely to trigger parse issue. The patch set including this one has been tested by the perf automated test: ./perf test parse -v" On haswell, ivybridge and Romley platform. The patch set also has been tested on haswell by the following script. Note: please make sure that your test system support TSX and L1-dcache-loads events. Otherwise, you may want to change the events to other pmu events.
