2019-09-20perf probe: Fix to clear tev->nargs in clear_probe_trace_event()Masami Hiramatsu1-0/+1
Since add_probe_trace_event() can reuse tf->tevs[i] after calling clear_probe_trace_event(), this can make perf-probe crash if the 1st attempt of probe event finding fails to find an event argument, and the 2nd attempt fails to find probe point. E.g. $ perf probe -D "task_pid_nr tsk" Failed to find 'tsk' in this function. Failed to get entry address of warn_bad_vsyscall Segmentation fault (core dumped) Committer testing: After the patch: $ perf probe -D "task_pid_nr tsk" Failed to find 'tsk' in this function.

2019-09-20perf probe: Skip same probe address for a given lineMasami Hiramatsu1-0/+19
Fix to skip making a same probe address on given line. Since a DWARF line info contains several entries for one line with different column, perf probe will make a different probe on same address if user specifies a probe point by "function:line" or "file:line". e.g. $ perf probe -D kernel_read:8 p:probe/kernel_read_L8 kernel_read+39 p:probe/kernel_read_L8_1 kernel_read+39 This skips such duplicated probe addresses.

2019-09-20perf kvm: Add arch neutral function to choose event for perf kvm recordAnju T Sudhakar3-1/+49
'perf kvm record' uses 'cycles'(if the user did not specify any event) as the default event to profile the guest. This will not provide any proper samples from the guest incase of powerpc architecture, since in powerpc the PMUs are controlled by the guest rather than the host. Patch adds a function to pick an arch specific event for 'perf kvm record', instead of selecting 'cycles' as a default event for all architectures. For powerpc this function checks for any user specified event, and if there isn't any it returns invalid instead of proceeding with 'cycles' event.

2019-09-20perf stat: Reset previous counts on repeat with intervalSrikar Dronamraju3-0/+21
When using 'perf stat' with repeat and interval option, it shows wrong values for events. The wrong values will be shown for the first interval on the second and subsequent repetitions. Without the fix: # perf stat -r 3 -I 2000 -e faults -e sched:sched_switch -a sleep 5 2.000282489 53 faults 2.000282489 513 sched:sched_switch 4.005478208 3,721 faults 4.005478208 2,666 sched:sched_switch 5.025470933 395 faults 5.025470933 1,307 sched:sched_switch 2.009602825 1,84,46,74,40,73,70,95,47,520 faults <------ 2.009602825 1,84,46,74,40,73,70,95,49,568 sched:sched_switch <------ 4.019612206 4,730 faults 4.019612206 2,746 sched:sched_switch 5.039615484 3,953 faults 5.039615484 1,496 sched:sched_switch 2.000274620 1,84,46,74,40,73,70,95,47,520 faults <------ 2.000274620 1,84,46,74,40,73,70,95,47,520 sched:sched_switch <------ 4.000480342 4,282 faults 4.000480342 2,303 sched:sched_switch 5.000916811 1,322 faults 5.000916811 1,064 sched:sched_switch # prev_raw_counts is allocated when using intervals. This is used when calculating the difference in the counts of events when using interval. The current counts are stored in prev_raw_counts to calculate the differences in the next iteration. On the first interval of the second and subsequent repetitions, prev_raw_counts would be the values stored in the last interval of the previous repetitions, while the current counts will only be for the first interval of the current repetition. Hence there is a possibility of events showing up as big number. Fix this by resetting prev_raw_counts whenever perf stat repeats the command.

Pruning a bit more the includes dependency tree. Building this thing on lots of containers takes time, we better reduce the time per build, each container is doing 6 builds when clang and clang-devel are available, and the plan is to do a 'make -C tools/perf build-test' that have many more. Also helps when doing normal development, as touching some random file will have a much reduced chance of triggering lots of rebuilds.

The xsk_socket__create() function fails and returns an error if it cannot get the XDP_OPTIONS through getsockopt(). However, support for XDP_OPTIONS was not added until kernel 5.3, so this means that creating XSK sockets always fails on older kernels. Since the option is just used to set the zero-copy flag in the xsk struct, and that flag is not really used for anything yet, just remove the getsockopt() call until a proper use for it is introduced.

commit "c016ae8f9fa04d361efc8629de49ad3af12b5262 "tools/power/x86/intel-speed-select: Output success/failed for command output" introduced a regression in perf-profile outputs. With this the result field is changed to string interpreting every non zero value as errors. But these commands display on zero (>0) result. For example before this commit the display was: package-1 die-0 cpu-14 get-config-levels:4 Here the get-config-levels is interpreted as error and displayed as error with the above commit: package-1 die-0 cpu-14 get-config-levels:failed(error 4) Fix this issue by not using isst_display_result() to display such results, but define a new function which formats this data and prints.
