icu/perf: Drop SPDX_S variable

2024-07-14T12:03:35+00:00

These were used by external layers and were needed before we had better unpack instrumenation and the recent unpack directory changes. Drop them as obsolete. (From OE-Core rev: 8dae8778ee14caebea92acd0bebf28c5681e39f3) Signed-off-by: Richard Purdie

bitbake.conf: Further cleanup compiler optimization flags

2024-07-13T22:28:30+00:00

Move the -pipe option out of the optimization flags and directly into the flags variables since we always use it now. Also move the debug prefix mapping there to match the nativesdk case which already does this. Fix the documentation and two recipe usages to match the change.

perf: drop newt from tui build requirements

2024-06-24T11:43:40+00:00

As the comment says this was used by very old kernels (pre 3.10), and slang has been the only option for a long time. Also, correct the option to disable slang TUI.

perf: make bpf asm include arch conditional

2024-04-08T22:33:32+00:00

To keep the perf source copying as small as possible, we can further refine the arch/uapi copy to the single file that we currently need. To avoid a warning from the general perf source copy routine, we make the .h conditional based on the architecture. The supported architectures will not change often, so updating this arch list is very minimal effort. Alternatively, we could add a PERF_OPTIONAL_SRC variable and not warn if a file isn't available for a given architecture.

perf: add asm include required for v6.9+

Kernel commit 9eea8fafe33e ("libbpf: fix __arg_ctx type enforcement for perf_event programs") added with 6.9-rc1 tools/include/uapi/asm/bpf_perf_event.h which for arc, arm64, loongarch, riscv and s390 includes headers from the arch/${ARCH}/... directories.

perf: fix TMPDIR contamination for recent mainline kernels

2024-04-04T20:50:24+00:00

The sed command sed -i -e "s,prefix='\$(DESTDIR_SQ)/usr'$,prefix='\$(DESTDIR_SQ)/usr' --install-lib='\$(PYTHON_SITEPACKAGES_DIR)' --root='\$(DESTDIR)',g" \ ${S}/tools/perf/Makefile.perf that was introduced by oe-core commit 43f96506 ("perf: fix the install-python_ext") [1] and adapted with oe-core commit 138673f8 ("perf: Fix reproducibility issues with 5.19 onwards") [2], patches the 'setup.py install' arguments for the 'install-python_ext' Make target similar to what the setuptools3_legacy.bbclass provides as ${SETUPTOOLS_INSTALL_ARGS}. However, this only applies to the linux-yocto kernel patched with linux-yocto commit 3fd60d4d ("perf: change --root to --prefix for python install") [3] that was introduced in 2012 and never went upstream in any way. For a recent mainline kernel instead, we will run into host path contamination QA warnings like: | WARNING: perf-1.0-r0 do_package_qa: QA Issue: File /usr/lib/python3.11/site-packages/perf-0.1-py3.11-linux-x86_64.egg/EGG-INFO/SOURCES.txt in package perf-python contains reference to TMPDIR | File /usr/lib/python3.11/site-packages/perf-0.1-py3.11-linux-x86_64.egg/__pycache__/perf.cpython-311.pyc in package perf-python contains reference to TMPDIR [buildpaths] To fix this, this commit introduces a replacement for Makefile.perf that results in the exact same setup.py install args as for the linux-yocto kernel. In oe-core commit c849ed0c ("perf: fix the install-python_ext on upstream kernel") [4], the sed that was originally meant for 'Makefile' only, was extended to 'Makefile*' (and thus including) Makefile.perf to fix similar issues. Since this would the affect the just-introduced Makefile.perf-specific sed, the scope of this extra sed was limited back to 'Makefile' only. The line could also be entirely removed maybe, since it seems to be for very old kernels only. In general, I would tend to argue that the above-mentioned linux-yocto patch for should be dropped if it requires additional sed-based patching anyway.

classes/recipes: Switch to use inherit_defer

2024-01-18T10:15:58+00:00

Now that bitbake supports the use of inherit_defer, switch all conditional (variable based) inherits to use this instead. This leads to more a more deterministic user experience since there is no longer an immediate expansion and later changes to the variables in question (e.g. a bbappend) are accounted for. This patch tries to ensure the behaviour before/after remains as unchanged as it reasonably can, e.g. by always inherting populate_sdk_base. native and nativesdk continue to need to be inherited last, hence being used with inherit_defer in a handful of very specific cases.

perf: fix build with latest kernel

2023-11-09T16:57:26+00:00

Kernel 6.7-rc1 commit 02e85f74668e ("tools: arm64: Add a Makefile for generating sysreg-defs.h") uses files from arch/arm64/tools/, gen-sysreg.awk and sysreg. Without the files the build of perf fails independent of the used architecture (confirmed with armv7 and qemux86_64). As arch/arm64/tools/ has been added with 5.13 allow perf to build even it that directory does not exist. Add arch/arm64/tools/ to PERF_SRC.
