perf: enable zstd in default PACKAGECONFIG

2025-02-27T10:55:17+00:00

The following upstream commit: commit 44b44ffd5dcef03d273ad070d0b02a65a323f5f6 Author: Leo Yan Date: Sun Dec 15 22:12:22 2024 +0000 perf build: Minor improvement for linking libzstd The zstd library will be automatically linked by detecting the feature libzstd. It is no need to explicitly link it for static builds, so remove the redundant linkage. It is contradictory to detect the feature libelf-zstd while the build configuration NO_LIBZSTD is set. Report an error for reminding users not to set NO_LIBZSTD.

Our build of perf and the other default features lead to libelf-zstd being detected, and hence the build aborts when the features are checked. We can't condionally enable this for 6.14+ kernels due to the way that the perf recipe works. The feature is minor and probably should have already been in the defaults. To keep things simple, we just enable it and will watch for any fallout.

meta/meta-selftest: Fix variable assignment whitespace

2025-02-01T13:42:34+00:00

Recipes are much more readable with whitespace around the assignment operators. Fix various assignments in OE-Core to show this is definitely the preferred formatting. (From OE-Core rev: 30ea609d3357fb3de911f2f6a5e6856c151b976a) Signed-off-by: Richard Purdie

Fix a minor typo in a comment by replacing "nsures" with ensures. (From OE-Core rev: c1f2df5616e9a14d1d6f2c993de8cc6204aea41f) Signed-off-by: Leon Anavi Signed-off-by: Richard Purdie

perf: add PACKAGECONFIG for zstd

2024-11-01T12:58:19+00:00

perf record can use zstd when available to provide on the fly compression. (From OE-Core rev: 1db5bc41e6c672a0c2ac104ee52dfdfe66ac67cd) Signed-off-by: Alexander Hirsch Signed-off-by: Richard Purdie

perf: Drop perl buildpaths skip

2024-08-08T07:26:14+00:00

According to my tests, enabling perl in PACKAGECONFIG and building doesn't show any buildpaths QA issue. Therefore drop this INSANE_SKIP as obsolete. (From OE-Core rev: f5f48a53507d73051c77159f423e555f3634b5fa) Signed-off-by: Richard Purdie

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.

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.
