perf: backport a fix for confusing non-fatal error

perf: fix compile error when rebuilding

2020-04-02T14:24:59+00:00

Fix error like: Makefile.perf:597: recipe for target 'intel_x86_64-wrs-linux/perf/1.0-r9/perf-1.0/perf-in.o] Error 2 Makefile.perf:220: recipe for target 'sub-make' failed make[1]: *** [sub-make] Error 2 Makefile:69: recipe for target 'all' failed make: *** [all] Error 2 during rebuilding, when kernel version changed, some source files also maybe changed. It could happened that the source under ${S} messed up with some already dropped files and also new files. Fix by clean the ${S} before copy source files.

perf: Fix externalsrc support

2020-03-10T23:20:33+00:00

When the externalsrc class is used the tasks listed in SRCTREECOVEREDTASKS are deleted to prevent them being executed. If externalsrc is used for the kernel then this will include virtual/kernel:do_patch. We can depend on do_shared_workdir instead as this will survive when externalsrc is used.

perf: Correct the substitution of python shebangs

2020-02-22T23:57:27+00:00

To make the native python3 always used, - Use sed one-liner instead - Add substitution for ${S}/scripts/bpf_helpers_doc.py to fix the following warning. File "/usr/lib/python3.6/sysconfig.py", line 421, in _init_posix _temp = __import__(name, globals(), locals(), ['build_time_vars'], 0) ModuleNotFoundError: No module named '_sysconfigdata' This issue is first reported by Joel Stanley The sed one-liner is credited to Anuj Mittal (From OE-Core rev: 3f93173130a94310255389cfc62c67102a4fb21b) Signed-off-by: He Zhe Signed-off-by: Richard Purdie

perf: Pass LDSHARED and CCLD via EXTRA_OEMAKE

2020-01-27T16:48:09+00:00

python code underneath is smart and pokes at python installation in sysroot for compile environment, the overrides from EXTRA_OEMAKE are ofcourse preferred but it falls back to python3's distutils/sysconfig for rest of them, and it does use CCLD and LDSHARED for linking, when we use clang to compile python3 then it encodes these variables to be clang however, when building perf we inherit kernel which forces gcc to be used for compiling perf, which then mixes both compilers due to CCLD and LDSHARED demands. Therefore override CCLD and LDSHARED in make environment helps python/distutils to use right linker (From OE-Core rev: f9259da409c2aa92deb71aef0da2405c8d836615) Signed-off-by: Khem Raj Signed-off-by: Richard Purdie

perf: fix build for v5.5+

2020-01-16T22:33:09+00:00

In kernel 5.5+ there are python3 scripts that explicitly use /usr/bin/python3 as the interpreter. That will find the host python and produce undefined results. We add that interpreter path to our substitutions to ensure that our sysroot variant is used.

perf: drop 'include' copy

2019-11-04T13:39:04+00:00

The copy of the kernel's top level include directory is not required to build perf. We have both the linux-libc-headers and perf's captured/copied headers for what it requires. The copy of the kernel's headers is leading us to multiple smaller fixes to ensure that the various .h files are in sync. We can remove the copy and all of the sync checks, and perf still builds and executes correctly.

perf: add 'cap' PACKAGECONFIG

2019-11-04T13:39:04+00:00

perf can use libcap when available, so we add a packageconfig for those that want the support. (From OE-Core rev: 9a35c61d2218e139aa4420ef25f8cf4a0c4c2cfc) Signed-off-by: Bruce Ashfield Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

perf: create directories before copying single files

2019-11-04T13:39:04+00:00

If we need to copy a single file from the linux source tree into the perf source tree, we need to ensure that the directory structure it requires has been created first.

perf: fix v5.4+ builds

2019-11-04T13:39:04+00:00

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.
