Hi, My XDP program was working fine with older version of clang/llvm (10) and when I moved to ubuntu 21.04, I ended up using version 12 and started seeing the problem during load: Validating xyz() func#1... arg#1 type is not a struct Arg#1 type PTR in xyz() is not supported yet. I can see it is coming from btf_get_prog_ctx_type, but not able to find the reason. The argument is a "void *". What am I missing ? Thanks Mohan
