License cleanup: add SPDX GPL-2.0 license identifier to files with no license Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

perf tools: Add 'cgroup_id' sort order keyword This patch introduces a cgroup identifier entry field in perf report to identify or distinguish data of different cgroups. It uses the device number and inode number of cgroup namespace, included in perf data with the new PERF_RECORD_NAMESPACES event, as cgroup identifier. With the assumption that each container is created with it's own cgroup namespace, this allows assessment/analysis of multiple containers at once. A simple test for this would be to clone a few processes passing SIGCHILD & CLONE_NEWCROUP flags to each of them, execute shell and run different workloads on each of those contexts, while running perf record command with --namespaces option. Shown below is the output of perf report, sorted with cgroup identifier, on perf.data generated with the above test scenario, clearly indicating one context's considerable use of kernel memory in comparison with others: $ perf report -s cgroup_id,sample --stdio # # Total Lost Samples: 0 # # Samples: 5K of event 'kmem:kmalloc' # Event count (approx.): 5965 # # Overhead cgroup id (dev/inode) Samples # ........ ..................... ............ # 81.27% 3/0xeffffffb 4848 16.24% 3/0xf00000d0 969 1.16% 3/0xf00000ce 69 0.82% 3/0xf00000cf 49 0.50% 0/0x0 30 While this is a start, there is further scope of improving this. For example, instead of cgroup namespace's device and inode numbers, dev and inode numbers of some or all namespaces may be used to distinguish which processes are running in a given container context. Also, scripts to map device and inode info to containers sounds plausible for better tracing of containers.

perf report: Add 'cgroup' sort key The cgroup sort key is to show cgroup membership of each task. Currently it shows full path in the cgroupfs (not relative to the root of cgroup namespace) since it'd be more intuitive IMHO. Otherwise root cgroup in different namespaces will all show same name - "/". The cgroup sort key should come before cgroup_id otherwise sort_dimension__add() will match it to cgroup_id as it only matches with the given substring. For example it will look like following. Note that record patch adding --all-cgroups patch will come later. $ perf record -a --namespace --all-cgroups cgtest [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.208 MB perf.data (4090 samples) ] $ perf report -s cgroup_id,cgroup,pid ... # Overhead cgroup id (dev/inode) Cgroup Pid:Command # ........ ..................... .......... ............... # 93.96% 0/0x0 / 0:swapper 1.25% 3/0xeffffffb / 278:looper0 0.86% 3/0xf000015f /sub/cgrp1 280:cgtest 0.37% 3/0xf0000160 /sub/cgrp2 281:cgtest 0.34% 3/0xf0000163 /sub/cgrp3 282:cgtest 0.22% 3/0xeffffffb /sub 278:looper0 0.20% 3/0xeffffffb / 280:cgtest 0.15% 3/0xf0000163 /sub/cgrp3 285:looper3 Signed-off-by: Namhyung Kim <namhyung@kernel.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lore.kernel.org/lkml/20200325124536.2800725-6-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

perf tools: Add dcacheline sort In perf's 'mem-mode', one can get access to a whole bunch of details specific to a particular sample instruction. A bunch of those details relate to the data address. One interesting thing you can do with data addresses is to convert them into a unique cacheline they belong too. Organizing these data cachelines into similar groups and sorting them can reveal cache contention. This patch creates an alogorithm based on various sample details that can help group entries together into data cachelines and allows 'perf report' to sort on it. The algorithm relies on having proper mmap2 support in the kernel to help determine if the memory map the data address belongs to is private to a pid or globally shared. The alogortithm is as follows: o group cpumodes together o group entries with discovered maps together o sort on major, minor, inode and inode generation numbers o if userspace anon, then sort on pid o sort on cachelines based on data addresses The 'dcacheline' sort option in 'perf report' only works in 'mem-mode'. Sample output: # # Samples: 206 of event 'cpu/mem-loads/pp' # Total weight : 2534 # Sort order : dcacheline,pid # # Overhead Samples Data Cacheline Command: Pid # ........ ............ ...................................................................... .................. # 13.22% 1 [k] 0xffff88042f08ebc0 swapper: 0 9.27% 1 [k] 0xffff88082e8cea80 swapper: 0 3.59% 2 [k] 0xffffffff819ba180 swapper: 0 0.32% 1 [k] arch_trigger_all_cpu_backtrace_handler_na.23901+0xffffffffffffffe0 swapper: 0 0.32% 1 [k] timekeeper_seq+0xfffffffffffffff8 swapper: 0 Note: Added a '+1' to symlen size in hists__calc_col_len to prevent the next column from prematurely tabbing over and mis-aligning.

perf report: Add "addr_from" and "addr_to" sort dimensions With the existing symbol_from/symbol_to, branches captured in the same function would be collapsed into a single function if the latencies associated with the each branch (cycles) were all the same. That is the case on Intel Broadwell, for instance. Since Intel Skylake, the latency is captured by hardware and therefore is used to disambiguate branches. Add addr_from/addr_to sort dimensions to sort branches based on their addresses and not the function there are in. The output is still the function name but the offset within the function is provided to uniquely identify each branch. These new sort dimensions also help with annotate because they create different entries in the histogram which, in turn, generates proper branch annotations. Here is an example using AMD's branch sampling: $ perf record -a -b -c 1000037 -e cpu/branch-brs/ test_prg $ perf report Samples: 6M of event 'cpu/branch-brs/', Event count (approx.): 6901276 Overhead Command Source Shared Object Source Symbol Target Symbol Basic Block Cycle 99.65% test_prg test_prg [.] test_thread [.] test_thread - 0.02% test_prg [kernel.vmlinux] [k] asm_sysvec_apic_timer_interrupt [k] error_entry - $ perf report -F overhead,comm,dso,addr_from,addr_to Samples: 6M of event 'cpu/branch-brs/', Event count (approx.): 6901276 Overhead Command Shared Object Source Address Target Address 4.22% test_prg test_prg [.] test_thread+0x3c [.] test_thread+0x4 4.13% test_prg test_prg [.] test_thread+0x4 [.] test_thread+0x3a 4.09% test_prg test_prg [.] test_thread+0x3a [.] test_thread+0x6 4.08% test_prg test_prg [.] test_thread+0x2 [.] test_thread+0x3c 4.06% test_prg test_prg [.] test_thread+0x3e [.] test_thread+0x2 3.87% test_prg test_prg [.] test_thread+0x6 [.] test_thread+0x38 3.84% test_prg test_prg [.] test_thread [.] test_thread+0x3e 3.76% test_prg test_prg [.] test_thread+0x1e [.] test_thread 3.76% test_prg test_prg [.] test_thread+0x38 [.] test_thread+0x8 3.56% test_prg test_prg [.] test_thread+0x22 [.] test_thread+0x1e 3.54% test_prg test_prg [.] test_thread+0x8 [.] test_thread+0x36 3.47% test_prg test_prg [.] test_thread+0x1c [.] test_thread+0x22 3.45% test_prg test_prg [.] test_thread+0x36 [.] test_thread+0xa 3.28% test_prg test_prg [.] test_thread+0x24 [.] test_thread+0x1c 3.25% test_prg test_prg [.] test_thread+0xa [.] test_thread+0x34 3.24% test_prg test_prg [.] test_thread+0x1a [.] test_thread+0x24 3.20% test_prg test_prg [.] test_thread+0x34 [.] test_thread+0xc 3.04% test_prg test_prg [.] test_thread+0x26 [.] test_thread+0x1a 3.01% test_prg test_prg [.] test_thread+0xc [.] test_thread+0x32 2.98% test_prg test_prg [.] test_thread+0x18 [.] test_thread+0x26 2.94% test_prg test_prg [.] test_thread+0x32 [.] test_thread+0xe 2.76% test_prg test_prg [.] test_thread+0x28 [.] test_thread+0x18 2.73% test_prg test_prg [.] test_thread+0xe [.] test_thread+0x30 2.67% test_prg test_prg [.] test_thread+0x30 [.] test_thread+0x10 2.67% test_prg test_prg [.] test_thread+0x16 [.] test_thread+0x28 2.46% test_prg test_prg [.] test_thread+0x10 [.] test_thread+0x2e 2.44% test_prg test_prg [.] test_thread+0x2a [.] test_thread+0x16 2.38% test_prg test_prg [.] test_thread+0x14 [.] test_thread+0x2a 2.32% test_prg test_prg [.] test_thread+0x2e [.] test_thread+0x12 2.28% test_prg test_prg [.] test_thread+0x12 [.] test_thread+0x2c 2.16% test_prg test_prg [.] test_thread+0x2c [.] test_thread+0x14 0.02% test_prg [kernel.vmlinux] [k] asm_sysvec_apic_ti+0x5 [k] error_entry Signed-off-by: Stephane Eranian <eranian@google.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Kim Phillips <kim.phillips@amd.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Song Liu <songliubraving@fb.com> Link: http://lore.kernel.org/lkml/20220208211637.2221872-13-eranian@google.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

perf top: Reuse the 'report' hist_entry/hists classes This actually fixes several problems we had in the old 'perf top': 1. Unresolved symbols not show, limitation that came from the old "KernelTop" codebase, to solve it we would need to do changes that would make sym_entry have most of the hist_entry fields. 2. It was using the number of samples, not the sum of sample->period. And brings the --sort code that allows us to have all the views in 'perf report', for instance: [root@emilia ~]# perf top --sort dso PerfTop: 5903 irqs/sec kernel:77.5% exact: 0.0% [1000Hz cycles], (all, 8 CPUs) ------------------------------------------------------------------------------ 31.59% libcrypto.so.1.0.0 21.55% [kernel] 18.57% libpython2.6.so.1.0 7.04% libc-2.12.so 6.99% _backend_agg.so 4.72% sshd 1.48% multiarray.so 1.39% libfreetype.so.6.3.22 1.37% perf 0.71% libgobject-2.0.so.0.2200.5 0.53% [tg3] 0.48% libglib-2.0.so.0.2200.5 0.44% libstdc++.so.6.0.13 0.40% libcairo.so.2.10800.8 0.38% libm-2.12.so 0.34% umath.so 0.30% libgdk-x11-2.0.so.0.1800.9 0.22% libpthread-2.12.so 0.20% libgtk-x11-2.0.so.0.1800.9 0.20% librt-2.12.so 0.15% _path.so 0.13% libpango-1.0.so.0.2800.1 0.11% libatlas.so.3.0 0.09% ft2font.so 0.09% libpangoft2-1.0.so.0.2800.1 0.08% libX11.so.6.3.0 0.07% [vdso] 0.06% cyclictest ^C All the filter lists can be used as well: --dsos, --comms, --symbols, etc. The 'perf report' TUI is also reused, being possible to apply all the zoom operations, do annotation, etc. This change will allow multiple simplifications in the symbol system as well, that will be detailed in upcoming changesets.

perf hists: Check if a hist_entry has callchains before using them So far if we use 'perf record -g' this will make symbol_conf.use_callchain 'true' and logic will assume that all events have callchains enabled, but ever since we added the possibility of setting up callchains for some events (e.g.: -e cycles/call-graph=dwarf/) while not for others, we limit usage scenarios by looking at that symbol_conf.use_callchain global boolean, we better look at each event attributes. On the road to that we need to look if a hist_entry has callchains, that is, to go from hist_entry->hists to the evsel that contains it, to then look at evsel->sample_type for PERF_SAMPLE_CALLCHAIN. The next step is to add a symbol_conf.ignore_callchains global, to use in the places where what we really want to know is if callchains should be ignored, even if present. Then -g will mean just to select a callchain mode to be applied to all events not explicitely setting some other callchain mode, i.e. a default callchain mode, and --no-call-graph will set symbol_conf.ignore_callchains with that clear intention. That too will at some point become a per evsel thing, that tools can set for all or just a few of its evsels.

perf tools: Move elide bool into perf_hpp_fmt struct After output/sort fields refactoring, it's expensive to check the elide bool in its current location inside the 'struct sort_entry'.
