RAD Telemetry 1.0j shipped!

Telemetry 1.0j is out the door! The big news, of course, is that there is alpha support for PS3 (PPU only) right now. If you're a PS3 developer please check it out and hammer on it, we need some data and use cases from the field.

Here are some of the major changes:

  • PS3 support (PPU only)

  • direct va_list support in all the vararg APIs. This was heavily requested and now it's in there!

  • race conditions/crashes in the run-time when the server went away unexpectedly should be reduced

  • added tmEndTryLockEx (just like tmEndTryLock but with explicit file/line)

  • new APIs! tmEnterThread and tmLeaveThread which allow you to specify the thread for the zone. This was crucial for 'logical thread' support (e.g. fibers, cooperative threads, etc.)

  • new APIs #2! tmBeginTimeSpanAt and tmEndTimeSpanAt allow you to specify the timestamps for timespan events, so you can time an external event and insert it retroactively

  • 360/Windows: significant performance boost in the context switch thread ("telemetry:ctxs")

  • TMOF_DEFAULT turns off context switches by default on Windows -- the overhead was just too high for users that didn't need it

The Visualizer got some love too:

  • Filter session lists by name and computer! This was requested quite a bit for customers had thousands of sessions to sift through.

  • Massive memory usage reduction for messages

  • Plot and memory events generate virtual messages in the message window (with a different color, and you can even now filter out all user messages if you want)

  • A bug with lock rendering was causing massive slow downs in certain special cases, fixed!

  • Localhost option has been removed since it was confusing and not very useful

  • Text entry fields should be normal now

  • Plots no longer render over the slider in the mini-timeline view

  • Clicking and dragging on a context switch span should still drag/scroll

  • Minimized timespan track would disappear

  • Paused frames are no rendered with a different color in the timeline view

  • Highlighting a context switch or lock event span highlights the appropriate subsection of a zone in the zone view

  • Timestamps are now inserted into the log entries when you use "Copy/Save To File"

And the server had some minor changes:

  • Bugfix: callstack processing wasn't processing last entry all the time

  • Change: -localhost option removed since it wasn't useful and confused people most of the time

  • Crash dump generator added, along with -minidump option to disable full memory crash dumps
