hi Daniel,
Thanks for liking the idea.
My target is embedded devices, that's why i get started from ebpf C.bcc
and bpftrace is a good idea, but i prefer taking one thing at a time,
what's more, i'm not familiar with python, it might take longer.
Once C code is accepted, i will move myself to bcc and bpftrace. Is it
ok for you?
BR

I'm planning to implement a couple of ebpf tools for preempt rt,
including irq latency, preempt latency and so on, how does it sound
to you?
Sounds great, thanks! Please add these tools for upstream inclusion
either to bpftrace [0] or
bcc [1], then a wider range of users would be able to benefit from them
as well as they are
also shipped as distro packages and generally more widely used compared
to kernel samples.
Thanks Song!
