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! [0] https://github.com/iovisor/bpftrace/tree/master/tools [1] https://github.com/iovisor/bcc/tree/master/libbpf-tools
