Hi Ceco, I am applying this patch-set. Thanks a lot!However, there is more work to do. Now, when we have the low-level API for eprobes, it is time to think for adding also some high-level APIs. You can have a look in:
tracecruncher/ft_utils.py and get some ideas from the classes 'kprobe' and 'kretval_probe' cheers, Yordan On 27.01.22 г. 9:01 ч., Tzvetomir Stoyanov (VMware) wrote:
Event probe (eprobe) is a new type of ftrace dynamic events, introduced
in the Linux kernel 5.15 version. It is useful to have support for them
in trace-cruncher, as it allows more flexibility when printing event's
data.
v3 changes:
- Added eporbe example.
v2 changes:
- Rebase.
- Moved unit test in a separate patch.
- Added a check in the unit test if the kernel supports eprobes.
- Renamed the API from PyFtrace_register_eprobe() to PyFtrace_eprobe(), for
consistency with the other dynamic events APIs.
