perf probe: Support probing on offline cross-arch binary Support probing on offline cross-architecture binary by adding getting the target machine arch from ELF and choose correct register string for the machine. Here is an example: ----- $ perf probe --vmlinux=./vmlinux-arm --definition 'do_sys_open $params' p:probe/do_sys_open do_sys_open+0 dfd=%r5:s32 filename=%r1:u32 flags=%r6:s32 mode=%r3:u16 ----- Here, we can get probe/do_sys_open from above and append it to to the target machine's tracing/kprobe_events file in the tracefs mountput, usually /sys/kernel/debug/tracing/kprobe_events (or /sys/kernel/tracing/kprobe_events).
