perf: disable parallelism for 'make clean'

2018-08-15T09:22:46+00:00

Whenever perf got rebuilt, I was consistently getting errors such as | find: '[...]/perf/1.0-r9/perf-1.0/plugin_mac80211.so': No such file or directory | find: '[...]/perf/1.0-r9/perf-1.0/plugin_mac80211.so': No such file or directory | find: find: '[...]/perf/1.0-r9/perf-1.0/libtraceevent.a''[...]/perf/1.0-r9/perf-1.0/libtraceevent.a': No such file or directory: No such file or directory | [...] | find: cannot delete '/mnt/xfs/devel/pil/yocto/tmp-glibc/work/wandboard-oe-linux-gnueabi/perf/1.0-r9/perf-1.0/util/.pstack.o.cmd': No such file or directory breaking the whole build. The root cause seems to be that the implicit 'make clean' done during do_configure ends up running in parallel, and thus multiple find commands attempt to stat and/or delete the same file. A patch disabling parallelism for the clean target has been ack'ed upstream (lkml.kernel.org/r/20180705134955.GB3686@krava), but it should be harmless to pass JOBS=1 even with a fixed kernel. This can be removed if and when all relevant -stable kernels have that patch.

perf: fix build with kernel older than 4.8

2018-08-15T09:22:45+00:00

* perf is failing to build for me since this oe-core commit: commit 9b38c824961fc9dce51bda95c25dac91a69fc64f Author: Hongxu Jia Date: Tue Apr 24 11:33:47 2018 +0800 perf: make a copy of kernel source to perf workdir the problem is that perf sources in kernel older than 4.8 (in my case 4.4) are depending on the "global" include headers outside tools directory, e.g. swab.h in: kernel-source/tools$ git grep swab.h perf/MANIFEST:include/linux/swab.h perf/MANIFEST:include/uapi/linux/swab.h perf/util/include/asm/byteorder.h:#include "../../../../include/uapi/linux/swab.h" this was resolved in 4.8 with: commit 7e3f36411342a54f1981fa97b43550b8406a3d69 Author: Arnaldo Carvalho de Melo Date: Mon Jul 18 17:42:16 2016 -0300 perf tools: Remove tools/perf/util/include/asm/byteorder.h Not used anymore. This also stops include linux/swab.h directly from the kernel sources, remove that reference from the MANIFEST. and few more changes to make tools/include more complete and standalone: tools/include in 4.15: asm asm-generic linux tools trace uapi tools/include in 4.4: asm asm-generic linux tools but copying the include header even for kernels which don't really need it doesn't add big overhead, so just copy include to perf sources for all kernels.

perf: make a copy of kernel source to perf workdir

2018-08-15T09:22:45+00:00

Since perf contaminates linux shared workdir, it probably caused kernel-devsrc compile failure at world build. ... |0 blocks |cpio: ./tools/perf/arch/arm/util/sedr7ORqk: Cannot stat: No such file or directory |0 blocks ... cpio tried to find a file at ${S}/tools/perf and failed if the input list is not valid. Make a copy of kernel shared source directory into a perf workdir could fix the issue.

perf: enable support for libaudit

2018-08-15T09:22:45+00:00

perf needs audit-python to be able to show syscall names and for 'perf trace' to work. Enable dependency on audit-python if present in PACKAGECONFIG. It's disabled by default since audit as of now is in meta-selinux.

meta: Drop further remnants of uclibc support

2017-06-22T08:16:00+00:00

uclibc support was removed a while ago and musl works much better. Start to remove the various overrides and patches related to uclibc which are no longer needed. uclibc support in a layer would still be possible. I have strong reasons to believe nobody is still using uclibc since patches are missing and I doubt the metadata even parses anymore.

Recent kernel build jvmti, java profiling agent, if a host jdk is detected. The library will be packaged in -dev and throws a qa error. Disable the jvmti build per default.

perf: use PACKAGECONFIG instead of hand-rolled logic

2017-01-19T22:47:21+00:00

PERF_FEATURES_ENABLE and perf_feature_enabled() was basically a poor man's clone of PACKAGECONFIG, without the automatic handling of dependencies and configure options. As part of the port to PACKAGECONFIG the options have been changed to remove the perf- prefix, but are otherwise unchanged. Also remove BUILDPERF_libc_uclibc assignment as nothing in the metadata uses a BUILDPERF variable.
