linux-headers

  • INSTALL_HDR_PATH="$CRSD"/usr only works with headers_install target (not headers)
  • find usr/include -name '.*' -delete does not remove Makefile and headers_check.pl
  • Remove usr/include/drm to use headers from libdrm
  • The headers_check target runs a few trivial sanity checks on the headers before install
    • checks if a header includes something nonexistent
    • checks if the declarations inside the headers are sane
    • checks if kernel internals are leaked into user space
    • not that useful for release tarballs but could come in handy when working with kernel git trees
