The two changes I wanted to make were the last two for Coresight warnings, but I ended up making some perf-wide changes along the way. For #1 (perf tools: Add WARN_ONCE equivalent for UI warnings) * Does it make sense to add warn once equivalents at all, or should the once be re-done for each usage? * Or should there be some kind of generic 'once' wrapper? For #3 (perf tools: Add disassembly warnings for annotate --stdio) * If the output is interpreted by any other tools, then adding these warnings could be an issue, so maybe this change could be dropped, but no error output at all isn't ideal. For #4 (perf tools: Add flag for tracking warnings of missing DSOs) * In theory I could re-use 'annotate_warned', but it might make sense to rename it in that case, or just leave the new auxtrace_warned and remove any confusion. This set applies to perf/core e73f0f0ee7541 Thanks James James Clark (6): perf tools: Add WARN_ONCE equivalent for UI warnings perf tools: Re-add annotate_warned functionality perf tools: Add disassembly warnings for annotate --stdio perf tools: Add flag for tracking warnings of missing DSOs perf cs-etm: Improve Coresight zero timestamp warning perf cs-etm: Add warnings for missing DSOs tools/perf/ui/browsers/annotate.c | 1 + tools/perf/ui/gtk/annotate.c | 1 + tools/perf/util/annotate.c | 20 +++++++++++++++++-- .../perf/util/cs-etm-decoder/cs-etm-decoder.c | 7 +++++-- tools/perf/util/cs-etm.c | 10 +++++++++- tools/perf/util/debug.h | 14 +++++++++++++ tools/perf/util/dso.h | 1 + 7 files changed, 49 insertions(+), 5 deletions(-) -- 2.28.0 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
