perf: lift TARGET_CC_ARCH modification out of security_flags.inc

2023-12-22T15:23:26+00:00

Building perf without security_flags.inc being included in one's distro results in the buildpaths warning WARNING: perf-1.0-r9 do_package_qa: QA Issue: File /usr/bin/trace in package perf contains reference to TMPDIR because the ${DEBUG_PREFIX_MAP} does not get used. Most recipes get that from CFLAGS, but the perf recipe explicitly unsets that. Now ${SELECTED_OPTIMIZATION} of course contains more than just ${DEBUG_FLAGS}/${DEBUG_PREFIX_MAP}. For most TUs, perf's build system adds its own optimization flags (-O6 for odd reasons), so for those including the -O2 or -Og doesn't change anything. But looking at the .o.cmd files show that there are some TUs which currently get built without any -O flag. So for those adding the distro's SELECTED_OPTIMIZATION seem to be the right thing to do.

recipes: Drop remaining PR values from recipes

2023-09-22T06:45:17+00:00

We've been removing PR values from recipes at upgrade time for a while. In general anyone maintaining a binary distro would end up having to curate these themselves so the values in OE-Core aren't really that useful anymore. In many ways it makes sense to clear out the remaining ones (which are mostly for 'config' recipes that are unlikely to increase in PV) and leave a clean slate for anyone implementing a binary distro config. References are left in meta-selftest since the tests there do involve them and their removal upon upgrade. (From OE-Core rev: d4c346e8ab8f3cae25d1b01c7331ed9f6d4f96ef) Signed-off-by: Richard Purdie

perf: disable perl support

2023-08-24T15:50:24+00:00

The perf support was broken and if enabled results in non-reproducible binaries, so disable it for now. (From OE-Core rev: 55463c1898c220b79b77da95b2d0dd9bdc1628a2) Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

perf: split scripting PACKAGECONFIG into perl and python

2023-08-24T15:50:24+00:00

There's no reason for Python and Perl support to be tied together, so split the PACKAGECONFIG into two. (From OE-Core rev: af1511065120b12600e39725d8507fa2c018ae1b) Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

perf: fix perl binding support

2023-08-24T15:50:24+00:00

The build of the perl integration has been broken for some time. Update the PERL_* variables so that it can find libperl in the new location. This then fails because the Perl headers cause warnings and the feature checks run with -Werror, so disable the errors. The perf-dbg package then has target build paths, so set INSANE_SKIP for now until this is resolved.

perf: add more PACKAGECONFIGs

2023-08-24T15:50:24+00:00

libpfm4 and babeltrace are enabled if they're found, so add PACKAGECONFIGs so that our configuration is explicit. (From OE-Core rev: 8818a259495310f3054abc2918771587e6f82ae9) Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

perf: enable verbose feature detection

2023-08-24T15:50:24+00:00

Having verbose feature detection is helpful to see exactly what has been enabled or disabled. (From OE-Core rev: d08de74d09a83d3bc94cce80f886bd2c6add416b) Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

perf: fix buildpaths QA warning in 6.4+

2023-07-10T10:36:34+00:00

kernel version 6.4 introduces a new file that need to have absolute paths removed, so we can avoid the buildpaths QA warning and have relocatable packages. We add pmu-flex.h to the processing, and the issue is resolved. (From OE-Core rev: b9f1d1ec162531e0ce59ea829ae570ca907b3448) Signed-off-by: Bruce Ashfield Signed-off-by: Richard Purdie

perf: Make built-in libtraceevent plugins cohabit with external libtraceevent

2023-05-31T15:53:04+00:00

This will package the plugins built by perf into kernel specific dir under libdir, so it does not conflict with plugins from newly added libtraceevent recipe Fixes do_sdk_depends: The file /usr/lib/traceevent/plugins/plugin_cfg80211.so is installed by both perf and libtraceevent, aborting (From OE-Core rev: 28f39769c27d257a60ff0152acc0c76f0276fa6a) Signed-off-by: Khem Raj Cc: Max Krummenacher Signed-off-by: Alexandre Belloni Signed-off-by: Richard Purdie

perf: add libtraceevent packageconfig

2023-05-22T09:53:47+00:00

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.
