Switch the perf_cpu_map in aggr_update_shadow from the evlist to the counter's cpu map, so the index is appropriate. This addresses a problem where uncore counts, with a cpumap like: $ cat /sys/devices/uncore_imc_0/cpumask 0,18 Don't aggregate counts in CPUs based on the index of those values in the cpumap (0 and 1) but on the actual CPU (0 and 18). Thereby correcting metric calculations in per-socket mode for counters without a full cpumask. On a SkylakeX with a tweaked DRAM_BW_Use metric, to remove unnecessary scaling, this gives: Before: $ /perf stat --per-socket -M DRAM_BW_Use -I 1000 1.001102293 S0 1 27.01 MiB uncore_imc/cas_count_write/ # 103.00 DRAM_BW_Use 1.001102293 S0 1 30.22 MiB uncore_imc/cas_count_read/ 1.001102293 S0 1 1,001,102,293 ns duration_time 1.001102293 S1 1 20.10 MiB uncore_imc/cas_count_write/ # 0.00 DRAM_BW_Use 1.001102293 S1 1 32.74 MiB uncore_imc/cas_count_read/ 1.001102293 S1 0 <not counted> ns duration_time 2.003517973 S0 1 83.04 MiB uncore_imc/cas_count_write/ # 920.00 DRAM_BW_Use 2.003517973 S0 1 145.95 MiB uncore_imc/cas_count_read/ 2.003517973 S0 1 1,002,415,680 ns duration_time 2.003517973 S1 1 302.45 MiB uncore_imc/cas_count_write/ # 0.00 DRAM_BW_Use 2.003517973 S1 1 290.99 MiB uncore_imc/cas_count_read/ 2.003517973 S1 0 <not counted> ns duration_time After: $ perf stat --per-socket -M DRAM_BW_Use -I 1000 1.001080840 S0 1 24.96 MiB uncore_imc/cas_count_write/ # 54.00 DRAM_BW_Use 1.001080840 S0 1 33.64 MiB uncore_imc/cas_count_read/ 1.001080840 S0 1 1,001,080,840 ns duration_time 1.001080840 S1 1 42.43 MiB uncore_imc/cas_count_write/ # 84.00 DRAM_BW_Use 1.001080840 S1 1 47.05 MiB uncore_imc/cas_count_read/ 1.001080840 S1 0 <not counted> ns duration_time Signed-off-by:Ian Rogers <irogers@google.com>

When a group has multiple events and the leader fails it can yield errors like: $ perf stat -e '{uncore_imc/cas_count_read/},instructions' /bin/true Error: The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (uncore_imc/cas_count_read/). /bin/dmesg | grep -i perf may provide additional information. However, when not the group leader <not supported> is given: $ perf stat -e '{instructions,uncore_imc/cas_count_read/}' /bin/true ... 1,619,057 instructions <not supported> MiB uncore_imc/cas_count_read/ This is necessary because get_group_fd will fail if the leader fails and is the direct result of the check on line 750 of builtin-stat.c in stat_handle_error that returns COUNTER_SKIP for the latter case. This patch improves the error message to: $ perf stat -e '{uncore_imc/cas_count_read/},instructions' /bin/true Error: Invalid event (uncore_imc/cas_count_read/) in per-thread mode, enable system wide with '-a'. v2.

In 'perf report', entering a recursive function from inside of itself (either directly of indirectly through some other function) results in calling symbol__annotate2 multiple() times, and freeing the whole disassembly when exiting from the innermost instance. The first issue causes the function's disassembly to be duplicated, and the latter a heap use-after-free (and crash) when trying to access the disassembly again. I reproduced the bug on perf 5.11.22 (Ubuntu 20.04.3 LTS) and 5.16.rc8 with the following testcase (compile with gcc recursive.c -o recursive). To reproduce: - perf record ./recursive - perf report - enter fibonacci and annotate it - move the cursor on one of the "callq fibonacci" instructions and press enter - at this point there will be two copies of the function in the disassembly - go back by pressing q, and perf will crash #include <stdio.h> int fibonacci(int n) { if(n <= 2) return 1; return fibonacci(n-1) + fibonacci(n-2); } int main() { printf("%d\n", fibonacci(40)); } This patch addresses the issue by annotating a function and freeing the associated memory on exit only if no annotation is already present, so that a recursive function is only annotated on entry.

Sort key 'p_stage_cyc' is used to present the latency cycles spent in pipeline stages. perf has local 'p_stage_cyc' sort key to display this info. There is no global variant available for this sort key. The local variant shows latency in a single sample, whereas the global value will be useful to present the total latency (sum of latencies) in the hist entry. It represents the latency number multiplied by the number of samples. Add global ('p_stage_cyc') and local variant ('local_p_stage_cyc') for this sort key. Use 'local_p_stage_cyc' as default option for "mem" sort mode. Also add this to the list of dynamic sort keys and made the "dynamic_headers" and "arch_specific_sort_keys" as static.

The most interesting bits as usual are the new platforms.

Only basic support is added for now. - NXP i.MX8 ULP8 is a new low-power variant of the widespread i.MX8 series. - TI SPEAr320s is a minor variant of the old SPEAr320 SoC that we have supported for a long time. New boards with the existing SoCs include - Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers - AT91/SAMA5 based evaluation board - NXP gains twenty new development and industrial boards for their i.MX and Layerscape SoCs - Intel IXP4xx now supports the final two machines in device tree that were previously only supported in old style board files. - Mediatek MT6589 is used in the Fairphone FP1 phone from 2013, while MT8183 is used in the Acer Chromebook 314. - Qualcomm gains support for the reference machines using the two new SoCs, plus a number of Chromebook variants and phones based on the Snapdragon 7c, 845 and 888 SoCs, including various Sony Xperia devices and the Microsoft Surface Duo 2. - ST STM32 now supports the Engicam i.Core STM32MP1 carrier board. - Tegra now boots various older Android devices based on 32-bit chips out of the box, including a number of ASUS Transformer tablets.
