Hi there,
I cannot build the `rtla` tool in the stable branch, version v6.6.80. The
root cause appears to be commit 41955b6c268154f81e34f9b61cf8156eec0730c0
which first appeared in v6.6.78. Here's how the build failure looks like
through Buildroot:
src/timerlat_hist.c: In function ‘timerlat_hist_apply_config’:
src/timerlat_hist.c:908:60: error: ‘struct timerlat_hist_params’ has
no member named ‘kernel_workload’
908 | retval = osnoise_set_workload(tool->context,
params->kernel_workload);
| ^~
make[3]: *** [<builtin>: src/timerlat_hist.o] Error 1
A quick grep shows that that symbol is referenced, but not defined
anywhere:
~/work/prog/linux-kernel[cesnet/2025-02-28] $ git grep kernel_workload
tools/tracing/rtla/src/timerlat_hist.c: retval =
osnoise_set_workload(tool->context, params->kernel_workload);
tools/tracing/rtla/src/timerlat_top.c: retval =
osnoise_set_workload(top->context, params->kernel_workload);
Maybe some prerequisite patch is missing?
With kind regards,
Jan
