2019-03-11perf ui browser: Fix ui popup argv browser for many entriesAndi Kleen
Fix the argv ui browser code to correctly display more entries than fit on the screen without crashing. The problem was some type confusion with pointer types in the ->seek function. Do the argv arithmetic correctly with char ** pointers. Also add some asserts to find overruns and limit the display function correctly. Then finally remove a workaround for this in the res sample browser. Committer testing: 1) Resize the x terminal to have just some 5 lines 2) Use 'perf report --samples 1' to activate the sample browser options in the menu 3) Press ENTER, this will cause the crash: # perf report --samples 1 perf: Segmentation fault -------- backtrace -------- perf[0x5a514a] /lib64/libc.so.6(+0x385bf)[0x7f27281b55bf] /lib64/libc.so.6(+0x161a67)[0x7f27282dea67] /lib64/libslang.so.2(SLsmg_write_wrapped_string+0x82)[0x7f272874a0b2] perf(ui_browser__argv_refresh+0x77)[0x5939a7] perf[0x5924cc] perf(ui_browser__run+0x39)[0x593449] perf(ui__popup_menu+0x83)[0x5a5263] perf[0x59f421] perf(perf_evlist__tui_browse_hists+0x3a0)[0x5a3780] perf(cmd_report+0x2746)[0x447136] perf[0x4a95fe] perf(main+0x61c)[0x42dc6c] /lib64/libc.so.6(__libc_start_main+0xf2)[0x7f27281a1412] perf(_start+0x2d)[0x42de9d] # After applying this patch no crash takes place in such situation.

2018-04-05perf ui browser: Fixup cleaning unused lines at the bottomArnaldo Carvalho de Melo
Now that we can have extra title lines we should use ui_browser->rows and not ->height when drawing lines, as well as adding ui_browser->extra_title_lines to browser->y when cleaning unused lines at the bottom, otherwise we end up clobbering with spaces the last line just shown by ui_browser->refresh() routine.

2018-04-03perf ui browser: Move the extra title lines from the hists browserArnaldo Carvalho de Melo
This will be useful for the annotate browser as well, that wants to have extra title lines, i.e. the current ui_browser unconditionally reserves the first line for a browser title and the last one for status messages. But some browsers, like the buckets one (hists browser) needs extra lines to show headers, allowing it to be shown or not, press 'H' in 'perf top' or 'perf report' to see this feature. So move that logic to the core ui_browser used by the hists_browser ('perf top' and 'perf report' main interface) so that it can be used by the annotate browser too.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman
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.

2017-07-18perf annotate: Implement visual marker for macro fusionJin Yao
For marking fused instructions clearly this patch adds a line before the first instruction of pair and joins it with the arrow of the jump to its target. For example, when "je" is selected in annotate view, the line before cmpl is displayed and joins the arrow of "je". │ ┌──cmpl $0x0,argp_program_version_hook 81.93 │ ├──je 20 │ │ lock cmpxchg %esi,0x38a9a4(%rip) │ │↓ jne 29 │ │↓ jmp 43 11.47 │20:└─→cmpxch %esi,0x38a999(%rip) That means the cmpl+je is a fused instruction pair and they should be considered together. Changelog: v3: Use Arnaldo's fix to improve the arrow origin rendering. To get the evsel->evlist->env->cpuid, save the evsel in annotate_browser. v2: new function "ins__is_fused" to check if the instructions are fused.

2015-12-09perf tui: Change default selection background color to yellowIngo Molnar
Boris reported that 'perf top' is unusable on his default 'black on white' terminal, which uses (eye friendly) light-grey as a background color. The reason is that the TUI cursor for the current selection line uses HE_COLORSET_SELECTED, and that has a default background color of 'lightgrey' - which is a common terminal background choice and thus the colors conflict. Use yellow as the background color instead: that should be an uncommon terminal background, yet it's still ergonomic on both black and white/grey terminals. [ It would be a better solution to straight out detect color collisions and resolve them reasonably by converting them to RGB and calculating color space distances, but I was unable to find proper documentation for SLtt_get_color_object() to recover the current color scheme so I gave up ...

2014-07-07perf ui browser: Add ->rows to disambiguate from ->heightArnaldo Carvalho de Melo
The ui_browser->height is about the whole browser "window", including any header, status lines or any other space needed for some "Yes", "No", etc buttons a descendent browser, like hist_browser, may have. Since the navigation is done mostly on the ui_browser methods, it needs to know how many rows are on the screen, while details about what other components are, say, if a header (that may be composed of multiple lines, etc) is present. Besides this we'll need to add a ui_browser->refresh_dimensions() hook so that browsers like hist_browser can update ->rows in response to screen resizes, this will come in a follow up patch. This patch just adds ->rows and updates it when updating ->height, keeps using ->height for the only other widget that can come with ui_browser, the scrollbar, that goes on using all the height on the rightmost column in the screen, using ->rows for the keyboard navigation needs.

Now that the map browser shares the input routine with the hists browser, there is no need for using any libnewt routine, so remove all traces except for honouring NO_NEWT=1 on the makefile command line as an indication that TUI support is not needed, in fact it just sets NO_SLANG=1.

2012-09-11perf tools: Use __maybe_used for unused variablesIrina Tirdea
perf defines both __used and __unused variables to use for marking unused variables. The variable __used is defined to __attribute__((__unused__)), which contradicts the kernel definition to __attribute__((__used__)) for new gcc versions. On Android, __used is also defined in system headers and this leads to warnings like: warning: '__used__' attribute ignored __unused is not defined in the kernel and is not a standard definition. If __unused is included everywhere instead of __used, this leads to conflicts with glibc headers, since glibc has a variables with this name in its headers. The best approach is to use __maybe_unused, the definition used in the kernel for __attribute__((unused)). In this way there is only one definition in perf sources (instead of 2 definitions that point to the same thing: __used and __unused) and it works on both Linux and Android. This patch simply replaces all instances of __used and __unused with __maybe_unused.

2012-05-03perf annotate browser: More clearly separate columnsArnaldo Carvalho de Melo
The first column (columns in the near future) are for the per line event overhead(s), that only appear when they are not zero. To clearly separate it, add back a solid vertical line, with just one colour, not influenced by the per line overheads. Then have the addr/offset column, then optionally the dynamic (static in the future) jump->target arrows, if 'j' enables it. Then the instructions.
