I've added uftrace live demo for its basic usage. Go and play with #uftrace. https://t.co/oVTvy7RCt1

LLVM official document introduces uftrace as a performance analysis tool for LLVM developers!

The document begins with
"uftrace is a great tool to generate rich profile data that you can use to focus and drill down into the timeline of your application."

Surprise video. The uftrace team updated to make the workflow easier in trace compass. https://t.co/RyugCJkup0

[Honggyu Kim @nexus26]

@sjpark0x00 That makes sense. Thanks for the explanation!

[Tanel Poder 🇺🇦 @TanelPoder]

@dendibakh @acmel Oh, uftrace might support this out of the box too, that's a yet another thing to test in my todo list :-)

* stddev output for uftrace report
* improved python tracing

Bonus Trace Compass Video: I tried tracing the #xz #backdoor. https://t.co/gbwooiSjJj I messed up in a few places but found some interesting behaviour nonetheless. I will improve the methodology and re-do this. Soonish.

[Matthew Khouzam @DavisTurlis]

For the first time in 6 years, the UFTrace parser in #tracecompass has been updated. @namhyung_foss thanks for tagging me, there was a old bug that slipped through initial testing. In case you're looking for the parser, you need to go to Tools->add ons... and click #uftrace.

DAMO v2.2.2 is released. The important change in this release is the introduction of 'replay' command[1]. It receives 'damo record' output and replay the recorded access pattern.

@DavisTurlis Thanks. I will think about it when I can find some time. I think there is no problem using the existing parser as we keep backward compatibility of ufrace data format. We didn't add anything special for python tracing.

[Honggyu Kim @nexus26]

uftrace is now able to trace more complicated python programs such as tensorflow and keras. It's explained at https://t.co/Mn5GWw3SeV.

This comes with @namhyung_foss Data Profiling series, an exciting new feature that has lots of potential, go try it!

There are examples & a link to a great LWN article about it in there.

[Namhyung Kim @namhyung_foss]

uftrace v0.15 comes with experiemental RISC-V support (64-bit only).
