Title:
Add Real-time Linux Analysis tool (rtla) to linux-tools
Status in linux package in Ubuntu:
Fix Committed
Status in linux source package in Noble:
Fix Committed
Bug description:
[Impact]
The **rtla** is a meta-tool that includes a set of commands that aims
to analyze the real-time properties of Linux.
Considering the latest "low-latency" capabilities acquired by the
generic kernel and also considering the recent trend in Ubuntu to
focus on performance and observability (see for example
https://ubuntu.com/blog/ubuntu-performance-engineering-with-frame-
pointers-by-default), it makes sense to provide more tools that can
help to analyze timing/responsive performance, such as rtla.
[Test case]
Simple rtla usage to measure the timer irq / timer thread latency:
$ sudo rtla timerlat
[Fix]
Enable the build of the rtla binary during the kernel build and ship
it with linux-tools.
[Regression potential]
The only potential regression is an increased amount of size in the
linux-tools package, due to the extra binary.
However, the binary itself is really small, the kernel already has all
the required capabilities enabled and we don't need to introduce any
additional user-space dependency, therefore such extra space is
expected to be minimal.
