* perf: add libtraceevent packageconfigMax Krummenacher2023-05-221-1/+2
| | | | | | | | | | | | | | | | | | | | | With kernel 6.4-rc1 commit 6898e60f709b ("perf build: If libtraceevent isn't present error the build") having libtraceevent is a required dependency unless building it with 'NO_LIBTRACEEVENT=1'. Older kernels did build libtraceevent as provided by the kernel sources. (Unless LIBTRACEEVENT_DYNAMIC=1 was defined, then it tried to pickup an external provided libtraceevent and printed a warning if not found.) Add a libtraceevent packageconfig which adds the dependency on libtraceevent if set, otherwise builds with NO_LIBTRACEEVENT=1. For older kernels the old behaviour of building libtraceevent from the kernel sources isn't changed.

With kernels < 6.4 pkg-config is only used for the gtk+-2.0 integration which is disabled in the OE config. Thus the issue wasn't exposed so far. With kernel 6.4 pkg-config is additionally used for libtraceevent and libtracefs.

* perf: fix buildpaths QA warningBruce Ashfield2023-03-111-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the 6.2+ kernel, arm64 perf has a buildpaths QA warning as a syscall table is now being dynamically generated. That generated table includes unistd.h by absolute path, which in turn triggers the buildpaths QA warning. This could easily be patched in linux-yocto, but that would leave the QA issue in perf built from other kernel trees. So we instead to the following: - Add the perf tools directory to the include path - Modify the Makefile to have a relative path to unistd.h and pass both the relative and absolute path to the generation script - Modify the generation script to take the relative location of unistd.h as a new parameter, and use that in the generated sycalls.c file At build, the added include path of the perf source allows the relative path file to be included, and no buildpaths warning is generated.

| | | | | | | | | | | | | | | | | | This was disabled in 2014[1] due to an error message which as far as I can tell, no longer occurs.

* perf: Fix 6.1 kernel reproducibility issueRichard Purdie2023-02-031-0/+4
| | | | | | | | | | | | | | | | | The pmu-events.c file is generated by a python script making os.scandir() calls. The return value is "order on disk" which can cary between machines. Add in a sed to fix the perf source to sort this data which makes the pmu-events.c file deterministic. We should try and upstream this change but we'll need to sed for varying kernel versions. We should also try and get the perf source being added to the perf-devsrc package so when failures like this occur, diffoscope is much more helpful!

* perf: sort-pmuevents: really keep array terminatorsLucas Stach2022-06-221-1/+4
| | | | | | | | | | | | | | | | | | | Commit e1382583cd50 ("perf: sort-pmuevents: don't drop elements") tried to fix a case where the array terminator elements were dropped from the sorted list breaking the build, but it only worked for the case where the terminator is the only element of the array. When the array has other elements the terminator will still be silently dropped, causing invalid memory accesses at runtime when the perf utility iterates over the array. Fix this by treating any unmatched entry as an array terminator and also add a comment to make it a little more clear how things are ending up at the right position in the sorted list.

* perf: Use python3targetconfig to ensure we use target librariesRichard Purdie2021-06-171-1/+1
| | | | | | | | | | | | | | | | | | We've seen some reproducibility issues on the autobuilder in perf where the size of the python module varies slightly between systems. After some head scratching and removing the --quiet option to the python module build, you can see it using -Lrecipe-sysroot-native in the linking commandline for the module. This means it is linking against the native library on systems where that works, skipping it and using the target one otherwise, probably with warnings in logs we've not seen. The fix is to inherit the python3targetconfig class which ensures that the target sysroot is used, then the byte differences between the builds go away and things are sane(r) again.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | perf has been failing our reproducible testing due to multiple symbols containg build paths. With this commit, we fix the issues: 1) The following line in the Makefle: override PYTHON := $(call get-executable-or-default,PYTHON,$(PYTHON_AUTO)) "PYTHON" / "PYTHON_AUTO" have the full path as part of the variable. We've ensure that the environment is setup and we do not need the full path to be captured, since the symbol gets built into the executable, making it not reproducible. 2) The following line: srcdir_SQ = $(patsubst %tools/perf,tools/perf,$(subst ','\'',$(srcdir))), Captures the full src path of perf, which of course makes it not reproducible. We really only need the relative location 'tools/perf', so we change the Makefile line to remove everything before 'tools/perf' 3) OUTPUT is the full path, we have python on the path so we remove it from the definition. This is captured in the perf binary, so breaks reproducibility PYTHONPATH="BUILD_STR(python) 4) To avoid bison generating #ifdefs that have captured paths, we make sure all the calls have YFLAGS, which contains prefix mapping information.

| | | | | | | | | | | | | | | | | | | | | | | | | | | When building perf for 5.4+, we have some new files that need to be copied (and synchronized) due to structural changes in the kernel source tree. Some of the issues these fixes are warnings, but none the less, they are worth fixing. - We copy arch/${ARCH}/Makefile, since it is source by some perf Makefiles - We copy scripts/, since the perf utilities are looking for files in that directory stucture. - We have *three* copies of ctypes.h in the tools/* hierarchy during the build. If the tools/perf/util/include/linux/ variant is used, it will trigger build errors since it is not complete. We copy the kernel's main include/linux/ctype.h to ensure they are in sync.

| | | | | | | | | | | | | | | | In the 5.3+ perf builds, there are multiple unistd.h files that need to be kept in sync. So not only do we update one, we update both to ensure that libc-headers and the perf build are in sync. perf checks some key files itself to be sure they are in sync, and bits.h can be out of sync. There's no build error that results with bits.h at the moment, but we still make sure they are in sync to avoid the configure/compile warning.

* perf: synchronize unistd.h between libc-headers and perf sourceBruce Ashfield2019-03-091-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the build for some architectures, perf generates a program which executes on the host to dump the syscall table. The generation of that program uses the cross compiler + sysroot to expand unistd.h. As such, we are getting the contents of that file from linux-libc-headers. The compilation of that generated program uses the host compiler and a restricted include path to the perf source code. In the perf source there is a captured unistd.h, as such it will be used when compiling the host executable. The perf source code is copied from the kernel version that is being built .. so we have a mismatch between the generation and the compilation of the host program. Normally this mismatch is fine, but if the libc-headers are newer than the kernel, we'll have syscalls (and their syscall numbers) that are not defined in the perf source code. This leads to a compiler error and a cascading failure of the perf build due to a missing generated file. To fix this, we can copy unistd.h from the recipe-sysroot into the perf source code and they will always be in sync.
