bcc: lower buildpaths from ERROR_QA to WARN_QA when ptest is enabled

bpftrace: move from dynamic-layers/openembedded-layer to dynamic-layers/meta-python

2024-09-04T07:18:50+00:00

* bpftrace itself doesn't depend on meta-python, but bpftrace from dynamic-layers/openembedded-layer depends on bcc from dynamic-layers/meta-python so better to move it there. This way both bcc and bpftrace are either both available at the same time or neither of them. * fixes https://github.com/kraj/meta-clang/issues/985 ERROR: Nothing PROVIDES 'bcc' (but /mnt/secondary/poky/meta-clang/dynamic-layers/openembedded-layer/recipes-devtools/bpftrace/bpftrace_0.20.1.bb DEPENDS on or otherwise requires it). Close matches: bc byacc NOTE: Runtime target 'bpftrace' is unbuildable, removing... Missing or unbuildable dependency chain was: ['bpftrace', 'bcc'] ERROR: Required build target 'core-image-minimal' has no buildable providers.

bcc: remove LUAJIT setting and related examples

2024-03-18T21:15:16+00:00

Current LUAJIT actually not works, below is snip of src/lua/CMakeLists.txt [snip] find_package(LuaJIT) find_program(LUAJIT luajit) if (LUAJIT_LIBRARIES AND LUAJIT) FILE(GLOB_RECURSE SRC_LUA ${CMAKE_CURRENT_SOURCE_DIR}/bcc/*.lua ${CMAKE_CURRENT_SOURCE_DIR}/bcc/vendor/*.lua ${CMAKE_CURRENT_SOURCE_DIR}/bpf/*.lua) ADD_CUSTOM_COMMAND( OUTPUT bcc.lua COMMAND ${LUAJIT} ${CMAKE_CURRENT_SOURCE_DIR}/src/squish.lua ${CMAKE_CURRENT_SOURCE_DIR} DEPENDS ${SRC_LUA} ${CMAKE_CURRENT_SOURCE_DIR}/squishy ) ADD_CUSTOM_COMMAND( OUTPUT bcc.o COMMAND ${LUAJIT} -bg bcc.lua bcc.o DEPENDS bcc.lua ) [snip] LUAJIT will be set when luajit is found. For oe, maybe we need to DEPENDS on luajit-native. But there are still 2 problems after I change DEPENDS from luajit to luajit-native and export LUA_PATH="${RECIPE_SYSROOT_NATIVE}/usr/share/luajit-2.1/?.lua" 1. luajit seems not support cross compile, if our target arch is different with build host, from above snip, luajit will compile out bcc.o with host arch, int this way, compile will failed with below error: "error adding symbols: file in wrong format". Refer [1], seems like option "-a" can used to generate other arch object. But luajit-native don't have this option: cortexa57-wrs-linux/bcc/0.29.1/recipe-sysroot-native/usr/bin/luajit [options]... [script [args]...]. Available options are: -e chunk Execute string 'chunk'. -l name Require library 'name'. -b ... Save or list bytecode. -j cmd Perform LuaJIT control command. -O[opt] Control LuaJIT optimizations. -i Enter interactive mode after executing 'script'. -v Show version information. -E Ignore environment variables. – Stop handling options. 2. if target arch is the same as build host(my test env is x86-64), bcc-lua is built out, but still have 2 problems, first, "bcc-lua /usr/share/bcc/examples/lua/bashreadline.lua" has a runtime error [2]. second, bcc-lua may try to find modules on host path: root@qemux86-64:/usr/share/bcc/examples/lua# bcc-lua ./kprobe-latency.lua bcc-lua: bcc.lua:3052: module 'syscall' not found: no field package.preload['syscall'] no file './syscall.lua' no file '/build/tmp-glibc/work/x86_64-linux/luajit-native/2.1/recipe-sysroot-native/usr/share/luaj' no file '/usr/local/share/lua/5.1/syscall.lua' no file '/usr/local/share/lua/5.1/syscall/init.lua' no file '/build/tmp-glibc/work/x86_64-linux/luajit-native/2.1/recipe-sysroot-native/usr/share/lua/' no file '/build/tmp-glibc/work/x86_64-linux/luajit-native/2.1/recipe-sysroot-native/usr/share/lua/' no file './syscall.so' no file '/usr/local/lib/lua/5.1/syscall.so' no file '/build/tmp-glibc/work/x86_64-linux/luajit-native/2.1/recipe-sysroot-native/usr/lib/lua/5.' no file '/usr/local/lib/lua/5.1/loadall.so' so remove LUAJIT setting and related examples first [1] https://luajit.org/running.html [2] https://github.com/iovisor/bcc/issues/1621 Signed-off-by: Changqing Li

distutils package no longer exists after python 3.12 upgrade. I haven't run ptest for this, but at least it will parse well now.

bcc: CMakeLists.txt: don't modify .gitconfig on build host nor try to update git submodules

2023-09-07T17:39:05+00:00

* bitbake fetcher will correctly handle safe.directory issues and blazesym or libbpf submodules are managed by gitsm:// fetcher we don't want to call git from CMake in do_configure * prevents many safe.directory entries in users .gitconfig when bcc was built in many different TMPDIRs added in https://github.com/iovisor/bcc/pull/4186 causing: [safe] directory = /OE/build/oe-core/tmp-glibc/work/cortexa57-oe-linux/bcc/0.28.0+git/git directory = /OE/build/oe-core/tmp-glibc/work/cortexa57-oe-linux/bcc/0.28.0+git/git/libbpf-tools/blazesym to be added for every TMPDIR where it was built Signed-off-by: Martin Jansa
