Perf bench epoll fails as below when attempted to run on on a powerpc system: ./perf bench epoll wait Running 'epoll/wait' benchmark: Run summary [PID 627653]: 79 threads monitoring on 64 file-descriptors for 8 secs. perf: pthread_create: No such file or directory In the setup where this perf bench was ran, difference was that partition had 640 CPU's, but not all CPUs were online. 80 CPUs were online. While creating threads and using epoll_wait , code sets the affinity using cpumask. The cpumask size used is 80 which is picked from "nrcpus = perf_cpu_map__nr(cpu)". Here the benchmark reports fail while setting affinity for cpu number which is greater than 80 or higher, because it attempts to set a bit position which is not allocated on the cpumask. Fix this by changing the size of cpumask to number of possible cpus and not the number of online cpus. Signed-off-by:

Tool events unnecessarily open a dummy perf event which is useless even with `perf record` which will still open a dummy event. Change the behavior of tool events so: - duration_time - call `rdclock` on open and then report the count as a delta since the start in evsel__read_counter. This moves code out of builtin-stat making it more general purpose. - user_time/system_time - open the fd as either `/proc/pid/stat` or `/proc/stat` for cases like system wide. evsel__read_counter will read the appropriate field out of the procfs file. These values were previously supplied by wait4, if the procfs read fails then the wait4 values are used, assuming the process/thread terminated. By reading user_time and system_time this way, interval mode, per PID and per CPU can be supported although there are restrictions given what the files provide (e.g. per PID can't be combined with per CPU). Opening any of the tool events for `perf record` is changed to return invalid. Signed-off-by:

On some s390 linux machine (mostly older models) and with debug packages installed, the test case 'perf annotate basic tests' runs for some longer time. Speed up the test and save the output of command perf annotate in a temporary file. This is used to perform pattern matching via grep command. This saves on invocation of perf annotate which runs for some time. Output before: # time bash -x tests/shell/annotate.sh >/dev/null 2>&1; echo EXIT CODE $? real 4m35.543s user 3m19.442s sys 1m14.322s EXIT CODE 0 # Output after: # time bash -x tests/shell/annotate.sh >/dev/null 2>&1; echo EXIT CODE $? real 2m2.881s user 1m30.980s sys 0m30.684s EXIT CODE 0 # Signed-off-by:

When multiple aggregation options are passed to perf stat the behavior isn't clear. Consider "perf stat -A --per-socket .." and "perf stat --per-socket -A ..", the first won't aggregate at all while the second will do per-socket aggregation, even though the same options were passed. Rather than set an enum value, gather the options in a struct and process them from most to least aggregate. This ensures the least aggregate option always applies, so no aggregation if "-A" is passed. Signed-off-by:

Reduce the scope of stat_options to cmd_stat, and pass as an argument to __cmd_record. This is done to make more localized changes to the options in later patches. A side-effect of the change is to reduce the size of a stripped PIE perf binary by 5952 bytes. The savings come mainly in the dynamic relocation section. Signed-off-by:

Data may have lots of overlapping mmaps. The regular insert adds at the end and relies on a later sort. For data with overlapping mappings the sort will happen during a subsequent maps__find or __maps__fixup_overlap_and_insert, there's never a period where the inserted maps buffer up and a single sort happens. To avoid back to back sorts, maintain the sort order when fixing up and inserting. Previously the first_ending_after search was O(log n) where n is the size of maps, and the insert was O(1) but because of the continuous sorting was becoming O(n*log(n)). With maintaining sort order, the insert now becomes O(n) for a memmove. For a perf report on a perf.data file containing overlapping mappings the time numbers are: Before: real 0m5.894s user 0m5.650s sys 0m0.231s After: real 0m0.675s user 0m0.454s sys 0m0.196s Signed-off-by:

When an 'after' map is generated the 'new' map must be before it so terminate iterating and don't resort. If the entry 'pos' is entirely overlapped by the 'new' mapping then don't remove and insert the mapping, just replace - again to remove sorting.

Allow filters to be added to perf top events. One use is to workaround issues with: ``` $ perf top --uid="$(id -u)" ``` which tries to scan /proc find processes belonging to the uid and can fail in such a pid terminates between the scan and the perf_event_open reporting: ``` Error: The sys_perf_event_open() syscall returned with 3 (No such process) for event (cycles:P). /bin/dmesg | grep -i perf may provide additional information. ``` A similar filter: ``` $ perf top -e cycles:P --filter "uid == $(id -u)" ``` doesn't fail this way.

Give the term types their own enum so that additional terms can be added that don't correspond to a PERF_SAMPLE_xx flag. The term values are numerically ascending rather than bit field positions, this means they need translating to a PERF_SAMPLE_xx bit field in certain places using a shift. Signed-off-by:

In general a read fills 4kb so filling the buffer is a 1 in 4096 operation, move it out of the io__get_char function to avoid some checking overhead and to better hint the function is good to inline.

Currently, the --no-desc option in perf list isn't functioning as intended. This issue arises from the overwriting of struct option->desc with the opposite value of struct option->long_desc. Consequently, whatever parse_options() returns at struct option->desc gets overridden later, rendering the --desc or --no-desc arguments ineffective. To resolve this, set ->desc as true by default and allow parse_options() to adjust it accordingly. This adjustment will fix the --no-desc option while preserving the functionality of the other parameters. Signed-off-by:

Test behavior of PMU names and comparisons wrt suffixes using Intel uncore_cha, marvell mrvl_ddr_pmu and S390's cpum_cf as examples. Signed-off-by:
-
Ian Rogers authored
The mrvl_ddr_pmu is uncore and has a hexadecimal address suffix while the previous PMU sorting/merging code assumes uncore PMU names start with uncore_ and have a decimal suffix. Because of the previous assumption it isn't possible to wildcard the mrvl_ddr_pmu. Modify pmu_name_len_no_suffix but also remove the suffix number out argument, this is because we don't know if a suffix number of say 100 is in hexadecimal or decimal. As the only use of the suffix number is in comparisons, it is safe there to compare the values as hexadecimal. Modify perf_pmu__match_ignoring_suffix so that hexadecimal suffixes are ignored. Only allow hexadecimal suffixes to be greater than length 2 (ie 3 or more) so that S390's cpum_cf PMU doesn't lose its suffix. Change the return type of pmu_name_len_no_suffix to size_t to workaround GCC incorrectly determining the result could be negative. Signed-off-by:
