Hi Jean and the list,

Attaching BPF to fentry/fexit hooks requires
arch_prepare_bpf_trampoline(), which
AFAIK has only been implemented on x86. Is there any related ongoing patch for
aarch64?

I've found a discussion [0] on this, and seems there has no further discussion.

Any thoughts?

Thanks!
Huichun

No patches have been posted since then.
If you have cycles to pick up this work it would be awesome!
