fwsgonzo / userspace

Userspace Linux platform

Installation

• Get a modern compiler
  • gcc 7.3 or later
  • clang-8 or later
• Create userspace services that includes userspace.cmake
• Build the userspace service like a normal CMake project
  • mkdir -p build && cd build
  • cmake ..
  • make -j16
• Run the resulting binary as a normal linux program
• You can avoid having to run with sudo with bridge permissions

Options

• Apply your own CMake code to the 'service' target:
  • target_link_libraries(service mylib)
• CMake options:
  • See the top of userspace.cmake
• For PGO training you will have to automate the process yourself

Testing it

Run one of the test services in /services with one of the scripts. If you get the error RTNETLINK answers: File exists, flush the interface with sudo ip addr flush dev bridge43. Where bridge43 is the interface name. You might have to do the same if the interface stops responding. If all else fails, restart your machine.
