Rename cpu_map__compare_aggr_cpu_id() to aggr_cpu_id__equal(), the cpu_map part of the name is misleading. Equal better describes the function than compare. Switch to const pointer rather than value as struct given the number of variables in aggr_cpu_id(). Reviewed-by:

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:John Garry <john.garry@huawei.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: James Clark <james.clark@arm.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Kajol Jain <kjain@linux.ibm.com> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Leo Yan <leo.yan@linaro.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Mathieu Poirier <mathieu.poirier@linaro.org> Cc: Mike Leach <mike.leach@linaro.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Clarke <pc@us.ibm.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Riccardo Mancini <rickyman7@gmail.com> Cc: Stephane Eranian <eranian@google.com> Cc: Suzuki Poulouse <suzuki.poulose@arm.com> Cc: Vineet Singh <vineet.singh@intel.com> Cc: coresight@lists.linaro.org Cc: linux-arm-kernel@lists.infradead.org Cc: zhengjun.xing@intel.com Link: https://lore.kernel.org/r/20220105061351.120843-4-irogers@google.comSigned-off-by:

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. Reported-by: -

Pull RISC-V SoC updates from Arnd Bergmann: "Add support for StarFive JH7100 RISC-V SoC This adds support for the StarFive JH7100, including the necessary device drivers and DT files for the BeagleV Starlight prototype board, with additional boards to be added later. This SoC promises to be the first usable low-cost platform for RISC-V.

Pull ARM SoC devicetree updates from Arnd Bergmann: "As usual, this is the bulk of the updates for the SoC tree, adding more devices to existing files, addressing issues from ever improving automated checking, and fixing minor issues. The most interesting bits as usual are the new platforms. All the newly supported SoCs belong into existing families this time: - Qualcomm gets support for two newly announced platforms, both of which can now work in production environments: the SDX65 5G modem that can run a minimal Linux on its Cortex-A7 core, and the Snapdragon 8 Gen 1, their latest high-end phone SoC. - Renesas adds support for R-Car S4-8, the most recent automotive Server/Communication SoC. - TI adds support for J721s2, a new automotive SoC in the K3 family. - Mediatek MT7986a/b is a SoC used in Wifi routers, the latest generation following their popular MT76xx series. 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. There is also a new Jetson AGX Orin developer kit. - Apple support adds the missing device trees for all the remaining M1 Macbook and iMac variants, though not yet the M1 Pro/Max versions. - Allwinner now supports another version of the Tanix TX6 set-top box based on the H6 SoC. - Broadcom gains support for the Netgear RAXE500 Wireless router based on BCM4908" * tag 'dt-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (574 commits) Revert "ARM: dts: BCM5301X: define RTL8365MB switch on Asus RT-AC88U" arm64: dts: qcom: sm6125: Avoid using missing SM6125_VDDCX arm64: dts: qcom: sm8450-qrd: Enable USB nodes arm64: dts: qcom: sm8450: Add usb nodes ARM: dts: aspeed: add LCLK setting into LPC KCS nodes dt-bindings: ipmi: bt-bmc: add 'clocks' as a required property ARM: dts: aspeed: add LCLK setting into LPC IBT node ARM: dts: aspeed: p10: Add TPM device ARM: dts: aspeed: p10: Enable USB host ports ARM: dts: aspeed: Add TYAN S8036 BMC machine ARM: dts: aspeed: tyan-s7106: Add uart_routing and fix vuart config ARM: dts: aspeed: Adding Facebook Bletchley BMC ARM: dts: aspeed: g220a: Enable secondary flash ARM: dts: Add openbmc-flash-layout-64-alt.dtsi ARM: dts: aspeed: Add secure boot controller node dt-bindings: aspeed: Add Secure Boot Controller bindings ARM: dts: Remove "spidev" nodes dt-bindings: pinctrl: samsung: Add pin drive definitions for Exynos850 dt-bindings: arm: samsung: Document E850-96 board binding dt-bindings: Add vendor prefix for WinLink ...
