2020-03-10bpftool: Introduce "prog profile" commandSong Liu1-0/+1
With fentry/fexit programs, it is possible to profile BPF program with hardware counters. Introduce bpftool "prog profile", which measures key metrics of a BPF program. bpftool prog profile command creates per-cpu perf events. Then it attaches fentry/fexit programs to the target BPF program. The fentry program saves perf event value to a map. The fexit program reads the perf event again, and calculates the difference, which is the instructions/cycles used by the target program. Example input and output: ./bpftool prog profile id 337 duration 3 cycles instructions llc_misses 4228 run_cnt 3403698 cycles (84.08%) 3525294 instructions # 1.04 insn per cycle (84.05%) 13 llc_misses # 3.69 LLC misses per million isns (83.50%) This command measures cycles and instructions for BPF program with id 337 for 3 seconds. The program has triggered 4228 times. The rest of the output is similar to perf-stat. In this example, the counters were only counting ~84% of the time because of time multiplexing of perf counters. Note that, this approach measures cycles and instructions in very small increments. So the fentry/fexit programs introduce noticeable errors to the measurement results. The fentry/fexit programs are generated with BPF skeletons. Therefore, we build bpftool twice. The first time _bpftool is built without skeletons. Then, _bpftool is used to generate the skeletons. The second time, bpftool is built with skeletons.

2020-03-06tools: Let O= makes handle a relative path with -C optionMasami Hiramatsu1-2/+2
When I tried to compile tools/perf from the top directory with the -C option, the O= option didn't work correctly if I passed a relative path: $ make O=BUILD -C tools/perf/ make: Entering directory '/home/mhiramat/ksrc/linux/tools/perf' BUILD: Doing 'make -j8' parallel build ../scripts/Makefile.include:4: *** O=/home/mhiramat/ksrc/linux/tools/perf/BUILD does not exist. Stop. make: *** [Makefile:70: all] Error 2 make: Leaving directory '/home/mhiramat/ksrc/linux/tools/perf' The O= directory existence check failed because the check script ran in the build target directory instead of the directory where I ran the make command. To fix that, once change directory to $(PWD) and check O= directory, since the PWD is set to where the make command runs.

2018-04-11Kbuild: fix # escaping in .cmd files for future MakeRasmus Villemoes1-0/+2
I tried building using a freshly built Make (4.2.1-69-g8a731d1), but already the objtool build broke with orc_dump.c: In function ‘orc_dump’: orc_dump.c:106:2: error: ‘elf_getshnum’ is deprecated [-Werror=deprecated-declarations] if (elf_getshdrnum(elf, &nr_sections)) { Turns out that with that new Make, the backslash was not removed, so cpp didn't see a #include directive, grep found nothing, and -DLIBELF_USE_DEPRECATED was wrongly put in CFLAGS. Now, that new Make behaviour is documented in their NEWS file: * WARNING: Backward-incompatibility! Number signs (#) appearing inside a macro reference or function invocation no longer introduce comments and should not be escaped with backslashes: thus a call such as: foo := $(shell echo '#') is legal. Previously the number sign needed to be escaped, for example: foo := $(shell echo '\#') Now this latter will resolve to "\#". If you want to write makefiles portable to both versions, assign the number sign to a variable: C := \# foo := $(shell echo '$C') This was claimed to be fixed in 3.81, but wasn't, for some reason. To detect this change search for 'nocomment' in the .FEATURES variable. This also fixes up the two make-cmd instances to replace # with $(pound) rather than with \#. There might very well be other places that need similar fixup in preparation for whatever future Make release contains the above change, but at least this builds an x86_64 defconfig with the new make.

2018-03-16arch: remove tile portArnd Bergmann1-10/+1
The Tile architecture port was added by Chris Metcalf in 2010, and maintained until early 2018 when he orphaned it due to his departure from Mellanox, and nobody else stepped up to maintain it. The product line is still around in the form of the BlueField SoC, but no longer uses the Tile architecture. There are also still products for sale with Tile-GX SoCs, notably the Mikrotik CCR router family. The products all use old (linux-3.3) kernels with lots of patches and won't be upgraded by their manufacturers. There have been efforts to port both OpenWRT and Debian to these, but both projects have stalled and are very unlikely to be continued in the future. Given that we are reasonably sure that nobody is still using the port with an upstream kernel any more, it seems better to remove it now while the port is in a good shape than to let it bitrot for a few years first.

2018-02-21tools: fix cross-compile var clobberingMartin Kelly1-0/+18
Currently a number of Makefiles break when used with toolchains that pass extra flags in CC and other cross-compile related variables (such as --sysroot). Thus we get this error when we use a toolchain that puts --sysroot in the CC var: ~/src/linux/tools$ make iio [snip] iio_event_monitor.c:18:10: fatal error: unistd.h: No such file or directory #include <unistd.h> ^~~~~~~~~~ This occurs because we clobber several env vars related to cross-compiling with lines like this: CC = $(CROSS_COMPILE)gcc Although this will point to a valid cross-compiler, we lose any extra flags that might exist in the CC variable, which can break toolchains that rely on them (for example, those that use --sysroot). This easily shows up using a Yocto SDK: $ . [snip]/sdk/environment-setup-cortexa8hf-neon-poky-linux-gnueabi $ echo $CC arm-poky-linux-gnueabi-gcc -march=armv7-a -mfpu=neon -mfloat-abi=hard -mcpu=cortex-a8 --sysroot=[snip]/sdk/sysroots/cortexa8hf-neon-poky-linux-gnueabi $ echo $CROSS_COMPILE arm-poky-linux-gnueabi- $ echo ${CROSS_COMPILE}gcc krm-poky-linux-gnueabi-gcc Although arm-poky-linux-gnueabi-gcc is a cross-compiler, we've lost the --sysroot and other flags that enable us to find the right libraries to link against, so we can't find unistd.h and other libraries and headers. Normally with the --sysroot flag we would find unistd.h in the sdk directory in the sysroot: $ find [snip]/sdk/sysroots -path '*/usr/include/unistd.h' [snip]/sdk/sysroots/cortexa8hf-neon-poky-linux-gnueabi/usr/include/unistd.h The perf Makefile adds CC = $(CROSS_COMPILE)gcc if and only if CC is not already set, and it compiles correctly with the above toolchain. So, generalize the logic that perf uses in the common Makefile and remove the manual CC = $(CROSS_COMPILE)gcc lines from each Makefile. Note that this patch does not fix cross-compile for all the tools (some have other bugs), but it does fix it for all except usb and acpi, which still have other unrelated issues. I tested both with and without the patch on native and cross-build and there appear to be no regressions.

Create two targets to remove executable and documentation that would have been previously installed with `make install` and `make doc-install`. Also create a "QUIET_UNINST" helper in tools/scripts/Makefile.include. Do not attempt to remove directories /usr/local/sbin and /usr/share/bash-completions/completions, even if they are empty, as those specific directories probably already existed on the system before we installed the program, and we do not wish to break other makefiles that might assume their existence.

2017-11-18kbuild: /bin/pwd -> pwdBjørn Forsman1-1/+1
Most places use pwd and rely on $PATH lookup. Moving the remaining absolute path /bin/pwd users over for consistency. Also, a reason for doing /bin/pwd -> pwd instead of the other way around is because I believe build systems should make little assumptions on host filesystem layout. Case in point, we do this kind of patching already in NixOS. Ref. commit 028568d84da3cfca49f5f846eeeef01441d70451 ("kbuild: revert $(realpath ...) to $(shell cd ... && /bin/pwd)").

By default all files without license information are under the default license of the kernel, which is GPL version 2.

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.

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.

I thought commit 8e9b46679923 ("kbuild: use $(abspath ...) instead of $(shell cd ... && /bin/pwd)") was a safe conversion, but it changed the behavior. $(abspath ...) / $(realpath ...) does not expand shell special characters, such as '~'.

2017-09-01kbuild: use $(abspath ...) instead of $(shell cd ... && /bin/pwd)Masahiro Yamada1-3/+3
Kbuild conventionally uses $(shell cd ... && /bin/pwd) idiom to get the absolute path of the directory because GNU Make 3.80, the minimal supported version at that time, did not support $(abspath ...) or $(realpath ...). Commit 37d69ee30808 ("docs: bump minimal GNU Make version to 3.81") dropped the GNU Make 3.80 support, so we are now allowed to use those make-builtin helpers. This conversion will provide better portability without relying on the pwd command or its location /bin/pwd. I am intentionally using $(realpath ...) instead $(abspath ...) in some places. The difference between the two is $(realpath ...) returns an empty string if the given path does not exist. It is convenient in places where we need to error-out if the makefile fails to create an output directory.

2017-06-06kbuild: simplify silent build (-s) detectionMasahiro Yamada1-7/+1
This allows to detect -s (--silent) option without checking GNU Make version. As commit e36aaea28972 ("kbuild: Fix silent builds with make-4") pointed out, GNU Make 4.x changed the way/order it presents the command line options into MAKEFLAGS. In Make 3.8x, 's' is always the first in a group of short options. The group may be prefixed with '-' in some cases. In Make 4.x, 's' is always the last in a group of short options. As commit e6ac89fabd03 ("kbuild: Correctly deal with make options which contain an 's'") addressed, we also need to deal with long options that contain 's', like --warn-undefined-variables. Test cases: [1] command line input: make --silent -> MAKEFLAGS for Make 3.8x: s -> MAKEFLAGS for Make 4.x : s [2] command line input: make -srR -> MAKEFLAGS for Make 3.8x: sRr -> MAKEFLAGS for Make 4.x : rRs [3] command line input: make -s -rR --warn-undefined-variables -> MAKEFLAGS for Make 3.8x: --warn-undefined-variables -sRr -> MAKEFLAGS for Make 4.x : rRs --warn-undefined-variables My idea to cater to all the cases more easily is to filter out long options (--%), then search 's' with $(findstring ...). This way will be more future-proof even if future versions of Make put 's' in the middle of the group. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2017-01-26tools build: Add tools tree support for 'make -s'Josh Poimboeuf1-1/+11
When doing a kernel build with 'make -s', everything is silenced except the objtool build. That's because the tools tree support for silent builds is some combination of missing and broken. Three changes are needed to fix it: - Makefile: propagate '-s' to the sub-make's MAKEFLAGS variable so the tools Makefiles can see it. - tools/scripts/Makefile.include: fix the tools Makefiles' ability to recognize '-s'. The MAKE_VERSION and MAKEFLAGS checks are copied from the top-level Makefile. This silences the "DESCEND objtool" message. - tools/build/Makefile.build: add support to the tools Build files for recognizing '-s'. Again the MAKE_VERSION and MAKEFLAGS checks are copied from the top-level Makefile. This silences all the object compile/link messages.

2016-07-22tools build: Fix objtool build with ARCH=x86_64Josh Poimboeuf1-0/+32
The objtool build fails in a cross-compiled environment on a non-x86 host with "ARCH=x86_64": tools/objtool/objtool-in.o: In function `decode_instructions': tools/objtool/builtin-check.c:276: undefined reference to `arch_decode_instruction' We could override the ARCH environment variable and change it back to x86, similar to what the objtool Makefile was doing before; but it's tricky to override environment variables consistently. Instead, take a similar approach used by the Linux top-level Makefile and introduce a SRCARCH Makefile variable which evaluates to "x86" when ARCH is either "x86_64" or "x86".

2012-11-19tools: Honour the O= flag when tool build called from a higher MakefileDavid Howells1-4/+13
Honour the O= flag that was passed to a higher level Makefile and then passed down as part of a tool build. To make this work, the top-level Makefile passes the original O= flag and subdir=tools to the tools/Makefile, and that in turn passes subdir=$(O)/$(subdir)/foodir when building tool foo in directory $(O)/$(subdir)/foodir (where the intervening slashes aren't added if an element is missing). For example, take perf. This is found in tools/perf/. Assume we're building into directory ~/zebra/, so we pass O=~/zebra to make. Dependening on where we run the build from, we see: make run in dir $(OUTPUT) dir ======================= ================== linux ~/zebra/tools/perf/ linux/tools ~/zebra/perf/ linux/tools/perf ~/zebra/ and if O= is not set, we get: make run in dir $(OUTPUT) dir ======================= ================== linux linux/tools/perf/ linux/tools linux/tools/perf/ linux/tools/perf linux/tools/perf/ The output directories are created by the descend function if they don't already exist.
