[PATCH RFC v3 0/4] Add cross-compilation support to eBPF samples

Show all headers | View raw

These patches fix issues seen when cross-compiling eBPF samples on arm64.
Compared to [1], I dropped the controversial inline-asm patch pending further
discussion on the right way to do it. However these patches are still a step in
the right direction and I wanted them to get in before the more controversial
bit.

Joel Fernandes (4):
  samples/bpf: Use getppid instead of getpgrp for array map stress
  samples/bpf: Enable cross compiler support
  samples/bpf: Fix pt_regs issues when cross-compiling
  samples/bpf: Add documentation on cross compilation
