[RFC PATCH v2 0/2] LoongArch: BPF: Add more feature for trampoline

Posted by Tiezhu Yang 1 month, 1 week ago

Please ignore the previous version, the code is a mess.
Sorry for the noise, this version fixed the mess code.

This is a RFC series, based on Hengqi's series [1]:

  LoongArch: Fix BPF trampoline related issues

The initial aim is to pass the following related testcase:

  sudo ./test_progs -a tracing_struct/struct_args
  sudo ./test_progs -a tracing_struct/struct_many_args
  sudo ./test_progs -a fentry_test/fentry_many_args
  sudo ./test_progs -a fexit_test/fexit_many_args

but there exist some other problems now, maybe it is related with
the following failed testcase:

  sudo ./test_progs -t module_attach

so just RFC for now, I will address the comments and send a formal
series once there are no problems.
